The most popular CNC machine in large shops and workshops is the 16A20F3 lathe

Manufacturer information

Near the workshop in Zamoskvorechye, the Bromley brothers began construction of a mechanical plant in 1857. His first products were axes, sickles and other tools for peasants. In 1864, the brothers purchased a new plot and began to obtain permission to build new workshop buildings.

In 1870 and 1872, planing and drilling machines from Zamoskvorechye received gold medals at the Moscow Industrial Exhibition. The triple expansion steam engine was awarded the Grand Gold Medal at the International Exhibition in Paris.

In 1918, the plant was nationalized and modernized. Since 1922, the plant has completely switched to the production of metal-cutting machines. In 1971, the first machines of the 16K20 series were produced. After the reconstruction of the plant, in 1973 they began to produce 16A20F3 with CNC.

Important!

Since 2016, the Moscow Machine Tool Plant has been located in New Cheryomushki. The production of CNC lathes has resumed.

Purpose and scope

The 16A20F3 CNC chuck-centering lathe is designed for external and internal processing of medium-sized workpieces with a diameter of up to 400 mm and a length of 1000 mm. The equipment produces a stepped and curved profile with an offset relative to the axis of rotation. The entire processing cycle takes place automatically.

Model 16A20F3 performs external and internal processing:

• turning of cylindrical surfaces in one axis and with offset;
• elements having conical, spherical and other complex profiles;
• drilling along the end and radius;
• boring;
• thread cutting.

The chuck-centering CNC machine 16A20F3 is designed for finishing processing of complex-profile parts. It produces crankshafts, connecting rods, earrings and other products, individually and in large quantities.

This machine uses an electric drive for the main movement KEMROS and an electric drive for feeds KEMTOR , so here are links to the documentation on these electric drives.

Location of components

Ball screw pairs of the X and Z axes have an increased service life due to reliable protection of the units. The spindle is high-precision, with a hole of 55 mm and 64 mm.

The frame has a chip removal conveyor. The support group consists of an apron and the base of a removable automatic turret. They are driven by a drive and a transverse movement VGK. The longitudinal movement of the tool is carried out through angular gears and a coupling from the VGK screws.

On the left above the frame in the housing there is a gearbox and spindle head. The chuck is installed mechanized and has its own electric drive. The tailstock is located on the bed guides. The quill is driven by an electromechanical drive. Push-button machine control panel. It is located on a bracket and easily changes its position.

Location of controls

The machine control panel is located at the top of the headstock. Below is a handle for setting the spindle speed. The handle for manual movement of the transverse caliper is located on its body, above the apron.

The longitudinal movement of the carriage in manual mode is activated by the handle at the point where the shafts are attached, on the left. It turns on in the direction of movement of the unit. Below on the control pedal frame:

• clamping and releasing the cartridge;
• supply and removal of quills.

The quill is clamped manually using a handle on its body.

Important!

Control of all nodes is duplicated on a remote unit.

On the rear guard of the unit, at the top, a symbolic information display unit is mounted. BOSI is an element of visualization of the machining process and adjusts machining taking into account tool wear. Control of the drives is displayed on the panel in the upper right corner of the fence. The equipment control panel is placed forward on a bracket.

Machine design, passport

The design of the 16A20F3 model has its own characteristics. The machine kit includes replaceable tool heads with a rotating axis and a number of tool holders of 6, 8, 12. On a high bed cast from SCh20 cast iron there are heat-treated guides of increased wear resistance. The caliper and tailstock move along them.

The spindle receives torque from the main drive through the gearbox and gearing. A chuck is installed on it to secure the workpiece. When working with rolled products, after cutting the finished part, the workpiece moves to the working area automatically.

The tool disc has slots for several cutters, depending on the model. In the longitudinal direction it moves together with the caliper. The lateral movement is provided by a drive located under the turret body. The feed box is located in the apron. It has its own electric drive. No more than 2 movements are activated at the same time.

Important!

For safety reasons, all rotating and moving components have guards with limit switches. The machine will not start working until all the shields are in place.
