Surface Grinder Features:
● The surface grinder's worktable guide surfaces and the lower guide rails are coated with PTFE plastic sheets, ensuring easy and flexible carriage movement and a long service life.
● The surface grinder's grinding head spindle is directly driven by a built-in motor, and the spindle bearings utilize ultra-precision rolling bearings. The motor rotor is dynamically balanced
to ensure low surface roughness during grinding. The main machine utilizes high-strength castings for excellent rigidity, and the guide rails have wide spacing for high grinding efficiency.
● Each moving part (kinematic pair) of the machine tool utilizes a solenoid valve oil pump for automatic, centralized oil supply, ensuring continuous lubrication of all parts of the machine tool.
