Equipment Highlights
● The machine tool adopts IN-FEED feed grinding theory, the servo motor drives the grinding wheel to move vertically, and the lower disk is driven by servo and synchronous belt, which can rotate in the same direction or opposite direction with the grinding wheel according to the needs of the process.
● This machine tool adopts precision cross roller bearing + deep groove ball bearing to support the workpiece spindle, which has high rigidity and precision; Vacuum adsorption method is used for clamping
Tooling or workpiece.
● The grinding head adopts an electric spindle to drive the grinding wheel to rotate, and adopts the classic screw + line rail + servo motor mode to drive vertical feed; The Z-axis adopts high-precision grating closed-loop feedback to control the Z-axis feed accuracy.
● The use of dual probe measuring instrument Marposs D-Model+2Unimar can achieve precise control of the grinding thickness dimensional error of the workpiece.
● Adopt interactive man-machine interface (touch screen), precise control and simple to use.
