SPLINE GRINDING MACHINE WITH CNC OSH-628.1.F3 VERSION 01

All the basic parts of the machine (bed, column, wheel head, table) are made of castings of gray cast iron, which ensures the preservation of accuracy parameters throughout the entire service life.

The bed has a T-shape. Relative to the bed, the table moves along the longitudinal sliding guides. The column is fixed in the back of the bed. The vertical guides of the column move the support of the wheel head. Closed roller linear guides are used as guides for vertical and transverse movement of the wheel head.

A wheel head with a spindle installed in it moves along the cross guides of the caliper. Protection of the work area is of cabinet type. The front wall has a sliding door with glass. An aerosol suction unit is connected to the back wall.

Movement of the table and the wheel head is carried out by means of high-precision, backlash-free ball-screw pairs. On the top surface of the table there are the headstock and tailstock, lunettes and the mechanism for dressing.

The grinding wheel dressing mechanism is fixed on the upper plane of the headstock. The radial diamond roller is mounted on a spindle with rotation from an asynchronous motor.

The headstock is designed for basing and turning (dividing) at a given angle of the workpiece.

The headstock consists of a cast iron body mounted on the top surface of the table, inside the body on high-precision angular contact ball bearings the spindle is mounted, in a conical hole (Morse 5) which the center for basing the part is installed. The spindle is rotated by an electric motor through a high-precision gearbox.

At the right end of the spindle, a leash is installed on the neck to transmit the torque of the workpiece. At the left end, a circular sensor for controlling the angle of rotation of the spindle is mounted.

The tailstock is designed for basing and clamping the workpiece. The base center is mounted on the upper surface of the mobile housing in a special socket. The rear center is moved manually along the rolling roller guides. The tailstock design allows you to adjust the position of the rear center in the vertical and horizontal plane.

The cooling system tank is a separate unit and is located at the back of the machine. Cleaning of the coolant is carried out by a magnetic separator.

To move along the programmable coordinates, the electric motors of the model 1FK7 and the drives Sinamics S120 of the company "Siemens"are used.

Linear and circular converters are used to provide feedback on Y, Z, and A coordinates.

The main drive is a high-speed spindle with a belt drive from an asynchronous motor with frequency control.

The angular orientation of the processed part is made according to the pre-processed cavity of the teeth using the “Renishaw” touch sensor. The touch sensor mechanism is located on the wheel head.
