M250 Grinding Machine
M250 grinder is a high-precision and high-efficiency surface grinder widely used in the mechanical processing industry. This machine tool is mainly used for grinding the outer circles and end faces of cylindrical and conical shapes, and is particularly suitable for small and medium-sized production workshops as well as tool repair workshops.
Main features
High precision machining:
The machine tool has a flexible structure, stable accuracy, and high grinding efficiency.
The design of the grinding wheel holder spindle system can fully ensure the precision of grinding processing and has sufficient strength and stiffness.
High degree of automation:
The longitudinal movement of the workbench can be achieved through hydraulic continuously variable transmission or handwheel transmission.
The horizontal movement of the grinding wheel holder has a hydraulic quick advance and retreat function.
Multifunctionality:
Suitable for grinding cylindrical and conical outer circles and end faces.
Especially suitable for small and medium-sized production workshops as well as tool and machine repair workshops.
Easy to operate:
The hydraulic drive of the machine tool adopts a screw pump, which runs smoothly and has low noise.
The feed guide uses plastic coated guide rails to improve the stability and service life of the machine tool.
Structural design:
The grinding wheel rack adopts a monolithic structure to increase rigidity.
The workbench consists of an upper workbench and a lower workbench, used for adjusting the taper of the workpiece.
