OD grinding machine 3L175

od grinding machine 3l175

OD grinding machines of the innovative model 3L175 are used in serial (as well as in large-scale) production for external processing of flat and cylindrical surfaces by the method of longitudinal and plunge-cut grinding. The latter allows you to grind shaped and stepped surfaces. Items are installed in centers.

A number of elements and processes are automated on the 3L175 model For example, longitudinal and plunge-cut grinding methods, as well as the necessary changes of the feeds of the circular, longitudinal, transverse types and the item revolutions in the process of grinding The top of the rotary table allows the grinding of tapered surfaces.


CAPABILITIES PROVIDED BY THE DESIGN OF THE MACHINE:

- the speed of the setting motion of the grinding wheelhead along the screw;

- purification precision of the used oil and used coolant;

- grinding using an active control device;

- retraction of the deadhead spindle when the grinding wheelhead is brought in;

- reliability of the blocking system, which prevents the likelihood of turning on the drives that rotate the grinding wheel spindle, as well as moving the table in the absence of lubrication;

- availability of a mechanism for manual movement of the table.

The motion of the table in the longitudinal direction is carried out by means of a hydraulic drive, due to which the required smoothness of regulation of the motion speeds is provided, as well as a change in the magnitude of delays at the extreme positions of the table.

The spindle of the grinding wheelhead is mounted on self-aligning hydrodynamic bearings, which ensure the stability of the spindle in case of heavy loads.

The motion of the grinding headwheel is carried out on roller guides. High feed accuracy is ensured due to the use of a rolling screw pair in the grinding wheel feed mechanism.

The motion of the deadhead spindle is performed in manual mode by means of a handwheel.

The supply of semi-automatic machines 3Л175 includes a mechanism for balancing the used grinding wheel on the move.
