    [0019] In the following description, various aspects of the present invention will be described. For purposes of explanation, specific configurations and details are set out in order to provide a concise understanding of the present invention. However, it will also be apparent to a person skilled in the art that the present invention can be practiced without the specific details presented here. In addition, well-known features can be omitted or simplified in order not to obscure the present invention.
    [0020] Reference is made to figures 1 and 2, representing the cutting tool 150, according to an embodiment of the present invention, in an assembled position and in an exploded view, respectively. The cutting tool 150 includes a cutting tool holder 100 and a cutting insert 152, attached to it. A cutting tool holder 100 has an internal continuous coolant passage 130 to provide tool refrigerant fluid C towards the cutting edge of cutting insert 152, attached to a cutting tool holder 100.
    [0021] The cutting tool holder 100 comprises a support body 102, an upper jaw 104 and a base jaw 106. The upper and lower jaws 104, 106 define an insert receiving cavity 108 between them, positioned at the front of the support body 102 and having a longitudinal cavity axis B. The upper jaw 104 and the base jaw 106 are coupled with the support body 102. In the present embodiment, the upper jaw 104 and the base jaw 106 are formed in a one-piece construction with support body 102. The upper jaw 104 has a front end 116 and a rear end 118. The upper jaw 104 and the base jaw 106 are spaced by an interstice 125, ending in a recess of resilience 110, positioned adjacent the rear end 118 of the upper jaw 104. The resilience recess 110 is bounded by a resilience recess wall 112 extending along a resilience recess axis A, transversely to the cavity axis B. The resilience recess axis A can be perpendicular to the cavity axis B and can even intercept the latter. The resilience recess wall 112 can be substantially cylindrical. Alternatively, the resilience recess wall 112 can be of any other shape. The interstice 125 and the resilience recess 110 allow the upper jaw 104 to resiliently deflect in the direction towards the base jaw 106, when a vertical force is applied thereon. The support body 102 is coupled with a longitudinal tool shank 158, extending backwards from the basic body 102. The support body 102 can be formed in a single construction in one piece with the tool shank 158. The shank tool number 158 can in turn be retained on a machine axis.
    [0022] Reference is also made to figures 3 and 4, representing a side view and a partially transparent side view of the cutting tool 150 of figure 1, respectively. In side views, the cutting tool 150 is displayed along the resilience recess axis A. A support body refrigerant channel 114 passes through the support body 102, and has a support body inlet 111 and an outlet support body 113. The support body outlet 113 is positioned in front of the support body inlet 111. The support body outlet 113 opens outwardly into the resilience recess wall 112 (i.e., the outlet support body 113 is in fluid communication with the resilience recess 110). The support body inlet 111 opens outwardly to a refrigerant source 156, providing refrigerant fluid C in the support body refrigerant channel 114. The tool refrigerant source 156 can be, for example, a refrigerant channel. shank 160, formed longitudinally through tool shank 158, and opening outwardly in the rear technique of tool shank 158. The orientation and coupling of the support body coolant channel 114 with the tool coolant source 156 , shown in the drawings, are to be considered as an example only, and do not in any way limit the present invention.
    [0023] An upper jaw refrigerant channel 120 passes through the upper jaw 104 and has an upper jaw entry 121 and an upper jaw outlet 123. The upper jaw entry 121 opens outward to the resilience recess wall 112, spaced from the support body outlet 113 (i.e., the upper jaw entry 121 is in fluid communication with the resilience recess 110). The upper jaw entry 121 can be positioned diametrically opposite the support body outlet 113. The upper jaw outlet 123 opens outwardly to the front end 116 of the upper jaw 104.
    [0024] A screw hole 124 extends vertically along a screw axis S, through the upper jaw 104, crossing the interstice 125 within the base jaw 106. In the side view of a cutting tool holder 100 (shown along the resilience recess axis A, figures 3-4), the screw axis S can be perpendicular to the cavity axis B. In other embodiments, the screw axis S can be angled at an acute angle or an angle obtuse with respect to cavity shaft B. The screw hole 124 portion extending into the base jaw 106 is a threaded hole portion 127. The screw hole 124 may intercept with the upper jaw coolant channel 120, as shown in figure 4. A cutting tool holder 100 can also include a set screw 122, inserted into screw hole 124. Set screw 122 has a head portion 144, a threaded portion 148, and a portion of neck 146 extending between and they. The neck portion 146 is narrower than the head portion 144 and the threaded portion 148. The neck portion 146 is also narrower than the screw hole 124, in particular in the upper claw coolant channel 120. When the screw fastener 122 is fixed to the screw hole 124, the threaded portion 148 cooperates with the threaded hole portion 127. Then, the head portion 144 applies a vertical force on the upper jaw 104, forcing it to deflect in the direction towards the base claw 106, and thus fix the cutting insert 152 in the insert receiving cavity 108. In addition, when the fixing screw 122 is fixed in the screw hole 124, the neck portion 146 of the same is positioned in the groove channel upper claw refrigerant 120.
    [0025] The cutting tool holder 100 also includes a compressible tool coolant plug 126, having a peripheral surface of plug 142. The peripheral surface of plug 142 conforms to the shape of the resilience recess wall 112, so that the refrigerant plug 126 fits into the resilience recess 110. The peripheral buffer surface 142 can be substantially cylindrical, having two opposing buffer end surfaces 140, between which the peripheral buffer surface 142 extends. Alternatively, the peripheral plug surface 142 can have any other shape that conforms to the shape of the resilience recess wall 112. For example, the peripheral surface of plug 142 can have a conical shape, in which case only a single end surface. buffer 140 can be connected to peripheral surface 142.
    [0026] A buffer refrigerant channel 128 passes through the refrigerant buffer 126, opening outwardly to the peripheral surface of buffer 142, into a buffer inlet 131 and a buffer outlet 133. The tool coolant plug 126 is inserted into the resilience recess 110, so that the plug inlet 131 faces the support body outlet 113, and the inlet plug 133 faces the upper jaw inlet 121. The buffer coolant channel 128 thus it provides a fluid path from the support body refrigerant channel 114 to the upper claw refrigerant channel 120, and makes the technique of the continuous refrigerant passage 130, from the refrigerant source 156 to the upper claw outlet 123.
    [0027] The tool coolant cap 126 is formed of a compressible material, such as a polymer (eg, polyurethane, elastomer and the like), allowing the tool coolant cap 126 to compress elastically under forces acting on the peripheral surface. of buffer 142. When the upper jaw 104 deflects resiliently towards the base jaw 106, for example, when the fixing screw 122 is attached, the resilience recess wall 112 secures the peripheral surface of the buffer 142, and compresses the tool coolant cap 126, thus keeping it in place.
    [0028] The diameter of the plug inlet 131 can be slightly larger than the diameter of the outlet of the support body 113, so that the outlet of the support body 113 is covered by the plug inlet 131. Similarly, the diameter of the outlet of the support buffer 133 is slightly larger than the diameter of the upper jaw entry 121. When the peripheral surface of buffer 142 is pressed tightly against the resilience recess wall 112, it covers and seals the support body outlet 113 and the jaw entry higher 121, and prevents refrigerant fluid C from leaking into the resilience recess 110. Refrigerant fluid C is thus only allowed to flow through buffer inlet 131, and advance through buffer refrigerant channel 128. Since the tool coolant cap 126 is formed of a compressible material, it does not resist the resilient deflection of the upper jaw 104 towards the base jaw 106. It is understood, however, that the compression extent of the tool coolant cap 126 will be limited by tightening the cutting insert 152 with the lower side of the upper jaw front end 116. Therefore, the length of travel of the front end 116 in tightening the cutting insert should be taken into account when determining the dimensions of the tool coolant plug 126 in relation to the dimensions of the resilience recess 110, together with the compressibility of the tool coolant plug 126 itself.
    [0029] The tool coolant plug 126 may further include two end plates, each affixed to one of the buffer end surfaces 140. The end plates are made of a harder material than the coolant plug material of tool 126, for example, they are made of metal (for example, aluminum or steel). The end plates cover at least a portion of the end surfaces of buffer 140, inter alia, in order to protect the tool coolant plug 126, for example, against perforation by metal chips removed from the machined workpiece.
    [0030] The compressible material forming the tool coolant plug 126, such as a polymer (e.g., polyurethane, elastomer and the like), is durable under typical metal machining temperatures in the 110 resilience recess, and aggressive chemical environment . For example, polyurethane can withstand temperatures typically up to 125 ° C without changing its properties. In addition, the compressible material is durable under contact with cutting tool refrigerant fluid C (for example, tool cooling emulsion, usually comprising oils, solvents and the like), which can be chemically abrasive. Accordingly, the refrigerant plug 126 is formed to withstand such metal machining conditions, i.e., typical temperatures and possibly chemically abrasive environment. Typical machining conditions can also include considerable friction, vibrations, and the like, and the tool coolant cap 126 is suitable for use also in such conditions.
    [0031] In addition, the compressible material forming the tool coolant plug 126 has a rebound resilience level. When the upper claw 104 is not deflected towards the base claw 106 (for example, when the clamping screw 122 is released), the tool coolant cap 126 resiliently resumes to assume its neutral position within the resilience recess 110 .
    [0032] As noted above, the neck portion 146 of the clamping screw 122 is positioned in the upper claw refrigerant channel 120, and the neck portion 146 is narrower than the screw hole 124 in the upper claw refrigerant channel. 120. Two sealing rings 138 (for example, rubber sealing rings) are positioned on both sides of the neck portion 146, having an outside diameter that corresponds to the diameter of screw hole 124 in the upper claw coolant channel 120 Thus, when the refrigerant fluid C advances through the upper claw refrigerant channel 120, it can flow around the narrower neck portion 146 of the set screw 122. However, the sealing rings 138 seal the screw hole 124 on both sides of the upper claw refrigerant channel 120, preventing refrigerant fluid C from leaking out of the upper claw refrigerant channel 120. Sealing rings 138 can be positioned in grooves d and sealing ring, wherein a first sealing ring groove is formed between the neck portion 146 and the head portion 144, and a second groove is formed between the neck portion 146 and the threaded portion 148.
    [0033] Still, reference is made to figures 6-9, representing the tool coolant plug 126 according to different modalities of the present invention. The tool coolant plug 126 may further include a positioning element 132 to determine the orientation of the tool coolant plug 126, i.e., to ensure that the plug inlet 121 is aligned with the outlet of the support body 113, and the plug outlet 133 is aligned with the upper jaw entry 121. The resilience recess wall 112 has a positioning groove 134 formed therein, corresponding to the shape of the positioning element 132.
    [0034] Figures 6 and 7 represent a modality of the tool coolant plug 126, in a perspective view and a transparent perspective view, respectively. In this embodiment, the positioning element 132 is in the form of a positioning pin 136, which protrudes out of the peripheral surface of the plug 142, for adjustment in the positioning slot 134. The positioning pin 136 is positioned in a bore. positioning pin 137, formed in the tool coolant plug 126 and opening outwardly to the peripheral surface of buffer 142. The positioning pin hole 137 extends substantially parallel to the buffer coolant channel 128.
    [0035] Figures 8 and 9 represent an alternative embodiment of the tool coolant plug 126, in a perspective view and a transparent perspective view, respectively. In this alternative embodiment, the tool coolant plug 126 has a positioning protrusion 162, extending outwardly from the peripheral surface of plug 142. The positioning protrusion 162 can extend, for example, from one of the end surfaces of buffer 140, in the direction of the buffer inlet 131 or the buffer outlet 133. In the embodiment shown in figures 8-9, the positioning protrusion 162 extends from the buffer end surface 140 in the direction to the buffer inlet 131, along the peripheral surface of buffer 142, generally perpendicular to the direction of the refrigerant channel of buffer 128. The positioning protuberance 162 can be formed in a unitary construction in one piece with the peripheral surface of buffer 142.
    [0036] When the tool coolant plug 126 is inserted in the resilience recess 110 along the resilience recess axis A, the positioning element 132 (e.g., the positioning pin 136 or the positioning protrusion 162) , slides into positioning slot 134. Tool coolant cap 126 can be inserted into resilience recess 110, only when positioning element 132 slides into positioning slot 134, thereby determining the orientation of the coolant plug tool 126 with respect to resilience recess 110. In this way, the orientation of the tool coolant plug 126 is maintained so that the plug inlet 131 faces the support body outlet 113, and the plug outlet 133 is facing the upper jaw inlet 121. This ensures the formation of the fluid path from the support body 114 coolant channel to the gas coolant channel. upper rra 120.
    [0037] In addition, the positioning element 132 is confined within the positioning groove 134, thereby preventing the tool coolant cap 126 from rotating about the resilience recess axis A, in relation to the resilience recess wall 112 The positioning element 132 is also stopped against the internal surface of the positioning slot 134, thereby preventing the tool coolant cap 126 from moving further into the resilience recess 110, and determining the location of the coolant cap of tool 126 along the resilience recess axis A.
    [0038] The cutting insert 152 has at least one cutting edge 154, to be used for cutting metal and other metal machining procedures. The cutting insert 152 shown in the drawings is an indexable cutting insert with two cutting edges 154. The upper jaw outlet 123 opens out towards the cutting edge 154. When the cutting tool refrigerant fluid C advances through the coolant passage 130, it is sprayed out of the upper jaw outlet 123, towards the cutting insert 152, and in particular towards the cutting edge 154. During machining operations, the refrigerant fluid C is required to cool the cutting edge 154 and the cutting area of the machined workpiece. In addition, the tool coolant C sprayed out towards the cutting edge 154 can be used to break or deflect metal chips removed from the workpiece.
    [0039] It should be noted that the cutting insert 152 can be any cutting insert suitable for attachment to a tool holder, such as in the insert receiving cavity 108 of the cutting tool holder 100. The cutting insert 152 shown in the accompanying drawings is a non-limiting example for the cutting insert, and the particulars of the insert receiving cavity 108 are also a non-limiting example for the insert receiving cavity. It will be understood that the insert receiving cavity 108 must be formed to be suitable for receiving any particular form of cutting insert.
    [0040] It is noted that, for certain machining operations, it is particularly desirable to provide cold refrigerant from above the cutting edge, that is, emerging from the upper clamping jaw. The coolant passage 130 of the cutting tool holder 100 according to the present invention is particularly suitable for cutting tools with limited space, sometimes insufficient for placing accessories or additional refrigerant supply elements.
    [0041] Reference to now made to figure 5, representing a top view of the cutting tool 150 of figure 1, viewed along the axis of screw S. A cutting tool holder 100 is tapered, more specifically narrowing from the direction of the tool shank 158, towards the insert receiving cavity 108 (i.e., towards the front end 116 of the upper jaw 104). The tool holder 100 has two lateral support surfaces 164, extending along the sides of the support body 102 and the upper and lower jaws 104, 106. When viewed along the screw axis S (that is, in the top view ), the lateral support surfaces 164 form a taper angle between them. In a particular embodiment of the cutting tool holder 100, the tapering angle oc can be an angle of 15 ° (i.e., c = 15 °), as shown in the drawings as a non-limiting example.
    [0042] The taper of the cutting tool holder 100 means that the front end 116 is narrower than the holder body 102, which leaves limited space to provide a passage for cutting tool coolant C, so that it would reach the cutting edge 154 from upper jaw 104 (i.e., from above cutting edge 154). Consequently, there is typically insufficient space to form a refrigerant channel within the support body 102, positioned above the resilience recess 110. Similarly, there is a limited possibility of installing external refrigerant supply elements, for example, on top of the upper jaw 104, or along the side support surfaces 164, so that it could spray coolant fluid from above the cutting edge 154. The addition of such external coolant supply elements may limit or obstruct the operation of the cutting tool 150, and is therefore undesirable.
    [0043] The cutting tool holder 100 according to the present invention has the advantage of the resilience recess 110, using it in the refrigerant passage 130, for the refrigerant fluid C to advance from the support body 102 in the direction for the upper jaw 104. This is achieved by the compressible tool coolant cap 126, installed in the resilience recess 110, and forming the coolant passage technique 130, without resisting the deflection of the upper jaw 104. Also, due to the limited space available, the upper claw refrigerant channel 120 can intercept with screw hole 124 (i.e., since there is insufficient space for the passage of refrigerant 130 to be spaced from screw hole 124). In addition, the refrigerant fluid C is allowed to flow through the upper claw refrigerant channel 120, around the fixing screw 122 and through the screw hole 124, towards the upper claw outlet 123, thus overcoming also the limited space restriction.
    [0044] Although the present invention has been described with reference to one or more specific embodiments, the description is intended to be illustrative as a whole and is not to be construed as limiting the invention to the embodiments shown. It is appreciated that various modifications may occur for those skilled in the art which, while not specifically shown here, are nevertheless within the scope of the invention.
