①The rotation of the main shaft of the headstock is controlled by the C axis, which is driven by 2Kw servo motor; the feeding of the left and right grinding heads is controlled by the X1 and X2 axes, and the lifting of the left grinding head is controlled by the Y1 axis, both are driven by servo; the reciprocating motion of the workbench is controlled by the Z axis, which is driven by servo motor + ball screw and flat V guide rail, with high precision and rigidity.
②This equipment is mainly for crystal spheroidal grinding, OF reference surface grinding and V NOTCH grinding, and is designed for crystal spheronization and OF reference surface grinding or V NOTCH grinding accuracy with one clamping process.
③The equipment has a high degree of automation and is easy to operate. This equipment clamps the workpiece with hydraulic cylinder, which is convenient, stable and reliable. The center height of the crystal can be manually calibrated by the dial indicator to ensure the reliability of the grinding outer circle size for higher machining accuracy.
④The machine tool is controlled by PLC + touch screen, with easy-to-learn programming for parts processing. The machine tool is also equipped with orientation instrument to ensure that the parts can be processed at one time to meet the requirements.
⑤This equipment is capable of processing silicon carbide 2''-8'', and the processing length of silicon carbide is 20-25mm; the orientation instrument is installed in front of the machine tool, and the X-ray tube is vapor proof; the combination of coarse and fine grinding wheels has high efficiency and precision in grinding the outer circle; the machine tool body and slide plate are all made of cast iron material and subject to aging treatment, which is reliable.
①The processing plan is customizable according to the size of the silicon carbide ingot
