- We adopt special type plan bearing at the spindle nose.(The extra is conical, the internal is cylindrical) this kind of structure is long serves life.
- We adopt a motor built-in type motor structure. This structure is compact and excellent rigidity.
- Worktable longitudinal movement and grinding head cross movement is supported by hydraulic system. They are stepless and variable speed.

This type of grinding machine is widely used across multiple manufacturing sectors for processing flat, planar components:
- Tool and die making: Fabricating precision dies, molds, cutting tools, and jig fixtures that demand ultra-smooth surfaces and accurate dimensions.
- Automotive industry: Machining engine parts (e.g., valve seats, cylinder head gaskets), transmission components, and brake discs to meet strict performance standards.
- Aerospace sector: Finishing lightweight alloy parts (aluminum, titanium) for aircraft frames, landing gear components, and sensor housings.
- General machinery manufacturing: Producing flat metal plates, bearing seats, and gear blanks for industrial equipment.
- Precision instrument production: Grinding components for measuring tools, medical devices, and electronic sensors where surface flatness is critical.
The rectangular worktable allows clamping multiple small workpieces simultaneously, while its reciprocating motion enables continuous grinding without frequent repositioning. This significantly boosts machining efficiency compared to manual grinding or smaller bench-top grinders, especially for batch processing of flat parts.Equipped with magnetic chucks for ferrous metals and vacuum/mechanical clamps for non-ferrous materials, the machine accommodates a wide range of workpiece materials (steel, aluminum, brass, ceramics) and sizes. Adjustable grinding parameters (wheel speed, feed rate, depth of cut) further expand its applicability to diverse machining tasks.
