Product Description
Typical machined parts
Main features of the machine tool
■ Huazhong CNC 808XPG/DG Two-Axis Interconnected System
■ Primarily used for machining cylindrical parts or multi-step cylindrical parts.
■ Cost-effective
Machine tool configuration
■ This machine tool is a CNC cylindrical grinder, suitable for both batch and small-to-medium volume production. It is primarily used to process cylindrical or multi-step cylindrical parts and offers excellent cost performance.
■ The machine tool’s electrical control system is standardly equipped with the 808XPG/DG two-axis linkage system provided by Wuhan Huazhong Numerical Control Co., Ltd.; the execution system uses CNC servo drives and servo motors.
■ The machine tool is simple and practical to operate—just a brief training session is all that’s needed to get started. Operators set the parameters for longitudinal grinding and plunge grinding via the CNC control panel, enabling automatic machining of workpieces with varying dimensions. This machine tool features an automatic table indexing function, allowing it to automatically grind multiple steps on a single workpiece. Moreover, the sequence of longitudinal grinding and plunge grinding, as well as the grinding process parameters, can be freely programmed for each step.
■ All moving parts are automatically lubricated; the tailstock offers both hydraulic and manual operation modes.
■ The workpiece, oil pump, and cooling pump are each driven by separate motors.
Grinding wheel head
It features automatic wheel dressing and automatic compensation functions.
■ Grinding wheel spindle
The spindle bearing of the grinding wheel headstock uses a three-lobe hydrodynamic bearing or an integral hydrodynamic sliding bearing. Alternatively, a high-precision hydrostatic-hydrodynamic spindle or a direct-drive electric spindle can be optionally selected according to user requirements.
■ Lateral feed
The longitudinal movement of the machine tool table and the lateral feed motion of the grinding wheel head are both driven by servo motors via ball screws, ensuring high feed accuracy. The machine is equipped with an operator panel featuring a user-friendly human-machine interface for convenient operation. Other systems can also be adopted according to customer requirements, and an online automatic measuring device can be optionally configured.
