Product Description

Typical machined parts

Main features of the machine tool

■ High-speed grinding with CBN wheels
■ Fully enclosed protective cover
■ Automatic measuring instruments from Zhongyuan Precision or Marposs
■ Integrated electrical cabinet
■ Independent centralized lubrication system

Machine tool configuration

■ High-speed grinding using CBN grinding wheels, suitable for batch production of outer cylindrical grinding of shaft-type parts with high precision and high hardness;
■ Equipped with Huazhong 808DG or Xinyi 21TA CNC system (other brands of CNC systems can also be configured upon user request).
■ Equipped with automatic measuring instruments from Zhongyuan Precision or Marposs (for end-face measurement and radial measurement), enabling a closed-loop automated grinding cycle to ensure dimensional machining accuracy.
■ By adopting synchronous rotation technology for the headstock and tailstock, we further enhance the roundness requirements for workpiece grinding, achieving a roundness of ≤0.001 mm. For workpieces that meet the synchronization drive requirements, it is possible to complete the grinding of the entire part’s outer diameter and end faces in a single clamping operation.
■ The workpiece clamping utilizes a large-stroke, slide-table structure driven by a servo motor coupled with a ball screw. This setup is suitable for switching between parts of various types and lengths, ensuring constant torque during the grinding process of the workpieces.
■ Install an integrated electrical cabinet (with air conditioning for the electrical cabinet).
■ Equipped with a separate centralized lubrication system to ensure timed and quantitative lubrication of the lead screw and guide rails.
■ Equipped with a fully enclosed protective cover, featuring an aesthetically pleasing design and ensuring safe and reliable operation.

Grinding wheel head

■ Lateral feed
It employs a linear motor drive, and the feed rails are equipped with Rexroth or THK linear guides. The ball screws are made in Taiwan.
Wan brand (other brands of ball screws can also be configured according to user requirements).

■ Vertical movement
The system employs a Yaskawa AC servo motor driven by a ball screw. The moving guide rails feature V-shaped plastic-coated flat guides and ball bearings.
The leadscrew uses a Taiwan-brand product (other brand ball screws can also be configured upon user request).

■ Grinding wheel spindle
The grinding wheel spindles all employ high-speed, rolling-bearing-type, hydrostatic and hydrodynamic spindle units or direct-drive electric spindles.

■ Adjust the spindle
Adopts a high-speed rolling bearing spindle unit.
