MK1320-550A (semi-protected) CNC cylindrical grinder

Main functional features:

1. Adopt special control system for grinding machine, imported high-precision ball screw for two shafts, and imported bearing support; Head rest structure: type A fixed, type B fixed and active; The Z axis guide rail surface of the machine tool is pasted with imported plastic soft belt, the X axis adopts imported precision roller guide rail, and the electrical control is Schneider Electric. The machine tool has the function of automatic correction and compensation of grinding wheel, and is externally connected with 1 μ M-band compensation switch, safety emergency exit protection and other functions.

2. The machine tool has high repeated positioning accuracy, strong grinding stability and low surface roughness value; It is easy to operate, easy to learn and use, and easy to realize automatic processing; It is widely used for grinding cylindrical surface, conical surface, arc shaped surface and multi-step shaft cylindrical parts.
