UNIVERSAL CIRCULAR GRINDING MACHINE WITH MASTER CONTROLLER OSH-518F2

DESCRIPTION

Designed for external and internal grinding of cylindrical, conical and end surfaces in the chuck and centers.

 The kinematics of the machine provides the following movements:
 - rotation of the circular grinding spindle (Sp axis);
- cross movement of the wheel head (X coordinate);
 - longitudinal movement of the table (Z coordinate); 
 - rotation of the workpiece (axis Sp1); 
 -rotation of the internal grinding spindle (SP2 axis);

The machine has manual and automatic control from the command controller. The machine has a layout with a moving table on which the workpiece is installed and the movement of the wheel head perpendicular to the axis of the centers relative to the workpiece. Basing of the processed parts is made in the centers of the headstock and tailstock or in the chuck.

  The working area of grinding is protected by an open type of protection, the front wall of the protection has a movable opening door with plexiglass.

  The work head and the tailstock are attached to the upper working surface of the movable table. The wheel head is moved along the linear rolling guides by means of a ball-screw transmission. The work head has the option of manual rotation to 90 degrees, wheel head has two spindles for external and internal grinding, it also has the ability to manually rotate an angle of ±30. The internal grinding spindle is rotary. The upper table can be rotated at an angle (3 ° clockwise and -3 ° counterclockwise) and is based on the lower table, which in turn moves along the slide rails of the frame.

The internal grinding spindle is rotary. The upper table can be rotated at an angle (3 ° clockwise and -3 ° counterclockwise) and is based on the lower table, which in turn moves along the slide rails of the bed. The periphery and end of the grinding wheel are dressed using dresser diamonds of the dressing mechanism installed on the upper table due to the longitudinal movement of the table and the transverse movement of the grinding wheel (linear interpolation by two coordinates).

  Hydraulic equipment is made by a separate unit and installed at the back of the machine, and the cooling system is on the left. There is an electric cabinet on the right side of the machine. In front of the machine, a combined control panel with a Siemens operator panel and a machine control panel with electronic flywheels, a joystick and control buttons are installed on the electric cabinet.
    When grinding, water-based coolant is used, and the coolant is cleaned using a magnetic separator and a filter conveyor. The treatment zone is supplied with coolant at a pressure of P = 2 ATM, the pump capacity is Q = 30 l/min. Proximity sensors of the company "Balluff". .
Low-voltage equipment of the company "Siemens". .
As a feedback, “Fagor” linear displacement converters are used.
