Precision Surface Grinding Machine with HT300 High-Grade Material 0.008mm Grinding Accuracy and C3 Grade Ball Screws
CNC Grinding Machine
ShangJie PM's CNC grinding machines are engineered for high-precision surface finishing and contour grinding of metal components. Featuring rigid structures, high-accuracy servo systems, and advanced control interfaces, these machines deliver exceptional repeatability and ultra-smooth finishes on steel, cast iron, and hardened alloys.
Suitable for molds, tools, shafts, and complex mechanical parts, CNC grinders are widely applied in aerospace, automotive, die-making, and precision manufacturing. Their automation capabilities, programmable parameters, and fine-feed control make them ideal for tasks requiring micron-level accuracy.
- High-rigidity design ensures consistent surface precision
- Suitable for flat, angular, and complex contour grinding
- Ideal for high-precision applications in mold and tooling industries
PSG/GM series machine tool adopts a gantry structure, with enlarged column and crossbeam box structure support, ensuring excellent rigidity of the entire machine. The castings of the machine tool are made of HT300 high-grade material, which has high strength, strong resistance to deformation, and excellent shock absorption capacity. The grinding accuracy within a 3-meter travel can reach within 0.008mm. The minimum feed rate of the Z-axis is 0.001mm.
Machine castings are made of HT300 high-grade material and undergo vibration stress relief and secondary tempering processes to eliminate internal stress. They feature high strength, strong resistance to deformation, and excellent shock absorption capacity, ensuring that the machine tool maintains stable precision over long-term use.

Machine Tool Configuration
The hydrostatic spindle has the advantages of high rotational accuracy, good rigidity, long service life and low noise. It can grind workpieces with high precision and high efficiency, and is an essential configuration for precision grinding machines.
The entire Adopting Japanese THK, German INA, Rexroth and Taiwan PMI SP grade ultra-precision linear guides.
The entire series of grinding machines adopt C3 grade high-precision ground ball screws, which operate smoothly without shock, have low wear and a long service life, effectively enhancing the working accuracy and stability of the machine tools.
The base of the electromagnetic chuck adopts steel plate milling cavity technology and all-copper coils. Compared with cast steel bases, it features a smaller volume and stronger magnetic force. The magnetic force is evenly distributed and adjustable, making it suitable for various heavy-duty and precision machining.
