CNC PROFILE GRINDING MACHINE OF THE LINEAR ROLLING GUIDEWAYS

This series of machine tools is a new upgraded version, adopts a gantry fixed beam structure, is equipped with a double vertical grinding head and an auxiliary grinding head, suitable for grinding the precision curved surface and other forming surfaces of the linear guide rail raceway, and can also assist in the small surface grinding. cut.

Features:

●Optimize the structure design of large parts such as the bed, worktable and grinding head. The machine has good rigidity, bending and torsion resistance, good working accuracy retention, significantly reduced surface roughness and waviness of the workpiece, high grinding efficiency, and easy operation of the machine , Reliable operation.

●The bed and worktable adopt flat-V plastic sliding guide rail pair, with small damping coefficient, stable operation of worktable and long service life. The reciprocating motion of the worktable is driven by a large pitch ball screw, which eliminates the influence of the temperature rise of the hydraulic oil on the accuracy of the machine tool.

●The horizontal movement of the grinding head adopts AC servo motor to drive the precision ball screw pair to move along the precision linear guide, with high positioning accuracy and repeat positioning accuracy.

●The dual vertical grinding head adopts a fixed structure in the vertical direction to ensure the accuracy of the grinding of the linear guide rail forming surface. The imported precision rolling bearing spindle is adopted, which has the advantages of high removal rate, low maintenance and use costs; the auxiliary grinding head can be vertically lifted And rotating at any angle, it can clamp and grind the tooling surface, the suction cup surface, the top surface of the workpiece, etc. at one time.

●The vertical grinding head grinding wheel dresser adopts diamond rollers for shaping and dressing, with high dressing accuracy.

●It is equipped with an automatic correction mechanism for the workpiece to reduce the clamping time of the workpiece and improve the grinding efficiency.

●The numerical control system has functions such as linear interpolation and circular interpolation, which can control the dual vertical grinding heads individually or in linkage control to realize automatic grinding and automatic dressing of the grinding wheel.

●The machine tool guide rail adopts automatic centralized lubrication, which effectively prevents the guide rail from straining.
