Cylindrical grinding machine 3Л131
The list of the main motions of 3Л131:
– table movement in the longitudinal direction (automatic and manual);
– movement of the grinding slide in the transverse direction (fast, automatic, manual, as well as approach-retraction);
– movement in a circle of the spindle of the headstock allows yu to rotate the workpiece as necessary;
– movement in the circular direction of the grinding wheel is intended for external and, accordingly, internal grinding.
The spindle of the machine is equipped with specialized hydraulic stops. They provide stable placement of the rotating axis of the spindle throughout the entire operational period (bypassing repair costs), and also make it possible to achieve the following indicators:
– roughness of the ground surfaces of 0.64 microns;
– tolerances of deviations from the required roundness in the cross section fit into 2.5 microns;
– constancy of the diameter of the longitudinal section (the degree of deviation from cylindricity) is within 10 microns.
