Product Description

Typical machined parts

Main features of the machine tool

■ Closed-loop automatic grinding work cycle
■ Zhongyuan Precision’s Automatic Measuring Instrument
■ Configure the electrical cabinet
■ Automatic quantitative lubrication
■ Fully enclosed protective cover

Machine tool configuration

■ This machine is suitable for mass production of shaft-type parts and can simultaneously grind both the end faces and outer circles in a single pass. Provided the grinding wheel width is sufficient, it can grind multiple steps and end faces in one go, enabling form grinding. The more complex the part’s geometry, the greater the advantage of this machine. Under favorable conditions, a single operator can handle multiple machines simultaneously.
■ Equipped with the Shiji Xing HNC-808DG two-axis linkage system from Wuhan Huazhong Numerical Control Co., Ltd. (other CNC systems can also be configured according to user requirements;)
■ The automated measuring instrument configured in the central area performs online measurements, enabling a closed-loop automatic grinding cycle to ensure machining dimensional accuracy. It can be combined according to specific user requirements (and other measuring instruments can also be configured based on user needs).
■ Equipped with a separate electrical cabinet (with air conditioning for the electrical cabinet) and a separate oil tank;
■ The tailstock features ball-bearing linear motion and is equipped with pneumatic extension and retraction functionality.
■ The headstock spindle and tailstock spindle both use a No. 4 Morse taper.
■ Equipped with an automatic quantitative lubrication pump to ensure sufficient lubrication of the lead screw;
■ The configured guard is fully enclosed to ensure safe operation;
■ Equip with an enlarged water tank and a magnetic separator or a paper filter.

Grinding wheel head

■ Wheelhead feed
The wheelhead feed and the worktable feed both utilize AC servo motors driven by ball screws. The ball screws are from a Taiwanese brand (other brands of ball screws can also be configured according to user requirements).

■ Guide rail
The grinding wheel headstock and worktable guideways are equipped with plastic-coated guideways to enhance their seismic resistance and sensitivity.

■ Grinding wheel spindle
The spindle of the grinding wheel headstock can adopt a hydrostatic, hydrodynamic, or static-pressure spindle, or a direct-drive electric spindle, ensuring high machining accuracy.
