Product details
MGA1432A high-precision universal cylindrical grinder
MGA1432A high-precision universal cylindrical grinder is mainly used for:
This machine tool is used to process shafts, sleeves, foil rollers, ring gauges, plug gauges, and other workpieces that require high precision and roughness. It is suitable for single or small batch processing of the above-mentioned precision parts. Machine tools are available in two specifications based on grinding length: 1000 and 1500, for users to choose from.
Structural features:
a、 The bearings of the machine tool grinding wheel frame adopt dynamic and static pressure bearings, which have high precision and good rigidity.
b、 The headstock spindle is driven by a DC motor and can be infinitely adjusted within the speed range.
c、 The tailstock adopts a dense ball bearing form, which has good rigidity.
d、 The machine tool is equipped with a grinding indicator, which facilitates high-precision grinding of the workpiece.
