Machines designed for two- and four-axis machining are produced with two turrets. The simultaneous operation of two turrets is ensured by their location: one 4 on the upper support 3, and the other 6 on the lower support 7. This arrangement makes it possible to use a large number of cutting tools for manufacturing complex parts .

Rotary carousel - with two racks and two calipers is designed for roughing and finishing of parts from ferrous and non-ferrous metals in a single and serial production. The turning and rotary machine is controlled by the pendant control panel, on which the control buttons and the display system are located .

Lathe - for cutting metal blanks in the form of bodies of revolution. Turning and boring of cylindrical, conical and shaped surfaces, threading, trimming and machining of the ends, drilling, countersinking and reaming of holes, etc. are performed on lathes.

Screw-cutting lathe

Screw-cutting lathe:

  1,2 - handles for switching the amount of feed; 3 - shift knob of the guitar mechanism; 4, 5 - handles for switching the spindle speed; 6 - handle transverse caliper; 7 - handle for securing the tool holder; 8 - handle for moving the upper slide; 9 - handle mounting pintles; 10 - a handle for fastening the tailstock: 11 - a flywheel for feeding the pintles; 12, 13 — mechanical feed control knobs: 14 — rack and pinion gear button; 15 - a flywheel of movement of a support; 16 - buttons to turn on and off the electric motor; 17 - reverse handle

Screw-cutting lathe 16K20 -

      relates to universal technological metal-cutting equipment used mainly in repair or other metal-working enterprises. Screw-cutting lathes are used for turning the external and internal surfaces of parts such as bodies of revolution of various axial profiles, as well as for cutting left and right threads: metric, inch, modular and pitch.

• The bed serves for mounting on it all the nodes of the machine .
• The headstock serves to transmit the rotation of the workpiece. In the case of the headstock mounted gearbox .
• The tailstock is used when machining the part in the centers to maintain its end, as well as to install drills, reamers when machining holes .
• The feed box is designed to transmit rotation to the drive shaft and lead screw, as well as to change the number of revolutions in order to obtain the necessary feeds .
• The apron is used to convert the rotational movement of the main shaft into the main rotor into the linear movement of the caliper .
• The caliper is designed to move the cutter mounted in the cutting head .

Turning tools: a - straight line through; b - bent through passage;

in - thrust checkpoint; g - cutting; d - cutting; e - shaped; g - threaded; h - boring boring .

Modern CNC lathes are used for processing external and internal workpieces and parts such as bodies of revolution. They perform all the same functions as conventional manually controlled lathes, however, the movements of the executive bodies of these machines are controlled by electronics - numerical program control and a system of drives and motors .

Designed for semi-automatic turning of the external and internal surfaces of parts such as bodies of revolution with a stepped and curved profile of varying complexity .

Allows you to sharpen bodies of revolution without the use of a mechanical copying unit or templates. High speed of reconfiguration and precision of processing allow to obtain a wide range of products, adapting to market demands .

Designed for cartridge and center machining with high precision in one or more passes of the outer and inner surfaces of parts such as bodies of revolution with a stepped and curved profile, of varying complexity, including threading. Processing can be done in one or more passes in a closed semi-automatic cycle simultaneously in two coordinates .
