Machine tool usage and performance characteristics
Adopting Siemens system or well-known domestic brand system, the 8.4 inch LCD display for external grinding wheel feed and worktable movement are both driven by AC servo motors through ball screws. The grinding wheel feed adopts a linear rolling guide to ensure sensitive feed and good rigidity.
The machine tool is equipped with automatic timed and quantitative lubrication to ensure the lubrication of the guide rail and screw.
The bed body is an integral structure with internal ribs arranged in a box shape, and is cast with high-strength low-alloy impregnated cast iron, which has been effectively treated. It has high overall stiffness and strength, meeting the requirements of efficient and high-precision equipment for basic components.
The spindle system of the grinding wheel rack adopts dynamic pressure bearings, and the grinding wheel spindle always maintains high rotational accuracy, rigidity, and working stability. And the grinding wheel frame is driven to feed through a ball screw. The grinding wheel rack guide rail adopts a straight rolling steel guide rail.
The worktable adopts a double-layer structure, which facilitates the adjustment of machine tool accuracy. The rotating worktable can grind conical surface parts.
The worktable moving mechanism adopts an AC servo motor to directly drive the ball screw pair and control the worktable movement. The workbench guide rail is a plastic coated sliding guide rail.
The cooling system is equipped with an independent cooling water tank to further ensure the quality of grinding.
According to the characteristics of continuous production, semi enclosed protection is configured to prevent coolant splashing and ensure a clean environment and the health of operators.
The machine tool electrical cabinet and machine tool protection device are integrated, with good sealing performance.
