    Apparatus for machining, polishing and/or smoothing workpieces having curved surfaces such as optical or ophthalmic lenses. A bearing head maintains a tool against a workpiece. Pressure is applied by a pneumatic piston and cylinder unit for establishing contact pressure between the workpiece and the tool. An eccentric drive mechanism including a compound table generates relative displacement between the workpiece and the tool. The pneumatic piston and cylinder unit actually forms part of the tool holder spindle. The cylinder or piston rod of the unit is provided with a tool holder block mounting the tool and the other of the piston rod or cylinder is attached to the drive mechanism. The bearing head has a freely rotating position and a locked position preventing rotation.

H two bushings 17 and 18, sliding along the uprights 19 and 20, the ends of which are provided with sleeves 21 and 22, sliding along the uprights 23 and 2, located perpendicular to the previous 19 and 20, and fixed to the frame 25 connected to the side walls of the casing 3. Such a design allows the movable table 16 to move in two mutually perpendicular directions. The table 16 is connected to the eccentric mechanism (Fig. 2), containing an eccentric 26 fixedly mounted on the end of the shaft 27 rotating around the axis 28 carrying the pulley 29. The eccentric mechanism also contains an additional eccentric 30 which idles the shaft 27 to form support, and connected with the pulley 31 for rotation around the axis 32. The eccentric trick 30 is supported by the support 33 fixed on the frame 25. The pulleys 29 and 31 have different diameters, driven by the same driving element - the shaft of the electric motor 3, fixed in the upper part of the skin and 3, and are connected to the engine by two belts 35 and 36 with a tensioning device 37 located on the length of the belt 35I to compensate for the impact of the eccentric 30. The shaft of the engine 3 provided for rotating in two directions causes the heads It transmits with the aid of a belt 36, pulleys 31 and 38 of the gearbox 39, on the output shaft of which the eccentric 0 (Fig. 3 and 5) is fixedly attached, connected with the end of the rectangular lever 41, the other end of which is attached to the lever 2 having other end of the head of the product. The connection of the rectangular lever tl - the lever k2 is carried out through a roller rotating in a sleeve fixed to the partition. Above the sleeve kk, the rectangular lever has an angular lever kb connected by a roller and a sleeve to another lever 42, the carrier of the second head 4 of the product. The head 4 is mounted freely on the lever 42 by means of the supporting axis 47 and being locked in the desired position. For this purpose, the head k has in the upper part a ts tane designed to form a continuation of the frontal end face of the lever H2, which has a device that secures the head in a stationary state in the required position corresponding to the A8 piece. This device consists of a handle 49, screwed into the lever 2, with a rim 50. The half-ring-shaped element is idle on the above-mentioned handle 49, and can occupy a free position, as shown in the drawing, at which rotation of the head 4 around its axis is possible, or the working position, as shown in the same figure by dashed lines, which secures the rotation of the head k by fastening the end of the lever 42 and the flat head 4 together. Screwing the handle 49 secures the element 44. the lower part of the head 4 has two diametrically opposite flats 51 and 52, one of which is located like the flat face 48 and has one radial bearing pin 53, and on the other there is a pair of radial parallel bearing fingers 5 and 55. The supporting axis 47 of the head 4 is generally transversal is located opposite to the corresponding holder 5. containing FIG. 2) the support block 5b for the cutting tool opposite the support fingers of the said head. Support pad 56 is provided with a device that allows for quick installation and removal of the cutting tool. It contains diametrically opposed side jaws 57, of which at least one is movably mounted by means of a spring 53. The pad 56 is on the part, which has the shape of a truncated cone 59 and serves as a protective shield that prevents the treatment products from penetrating to the holder 5 and the drive mechanism. The pump 60 is designed to provide a flow of working medium under pressure through the tube 61, and a filter 62 to clean the medium before entering the pump to repeat the cycle. When machining an annular or cylindrical surface, the processed lens 63 is brought into contact with a cutting tool 6 with a corresponding head k. Such a construction leads to the acquisition of an orbital complex motion on the tool holder, and on the head - a tamper motion. The proposed machine allows improving the quality of processing by creating a trace uniqueness on the product. that, in order to improve the quality of processing, the kinematic connection of the drive with the tool holder is made in the form of a table connected to a pressing mechanism by means of an elastic coupling and mounted in two mutually perpendicular directions from an eccentric mounted on a shaft, carrying a pulley connected to the drive, and the machine is additionally provided freely supported on the said shaft, which is mounted on a pulley connected to the drive, wherein the pulleys are made with different diameters.
