3Д4230 cylindrical grinding machine
Grinding on 3Д4230 cylindrical grinding machine is carried out with plunge feed manually of grinding wheel. 3Д4230 is suitable for machining smooth cylindrical and tapered surfaces with a taper angle of 3 ° 30 ‘. Re-grinding the crankshaft main journals is possible not only in the centers, but also in chucks.
The machine has accuracy class B according to GOST 8-82. For individual orders and for a separate surcharge, accuracy class A is also available.
A number of kinematic chains, as well as a hydraulic drive, makes it possible to produce movements of the following nature:
– rotate the product and grinding wheel;
– promptly (using hydraulics) bring and remove the grinding headstock;
– carry out the transverse feed of the grinding wheel manually;
– move the table manually, as well as using hydraulic drive;
– produce axial movement of the tailstock quill;
– vertically move clamping chucks.
