1. This surface grinder's base, table and column are made of high quality Meehanite cast iron for high rigidity and stability for maintaining long-time accuracy;
2. Reinforcement ribbed base and H-frame column guarantee the premium anti-vibration and high rigidity for this surface grinder;
3. Table travels left/right longitudinally on rolling ball steel guide ways. The high-density and wearing-resistant rolling balls ensure the table to move smoothly and lightly with high efficiency. Furthermore, the table's left/right travels are driven through the synchronous belts, ensuring the high stability for the movements;
4. Double "V" type guide ways for table's back/front travels on the saddle ensure the high rigidity. They are precision hand scrapped to obtain high precision. The back/front movements are operated with the precision ball screw, ensuring high precision movements;
5. Totally closed spindle motor runs free of vibration with low noise. It is directly mounted onto the spindle;
6. Precision cartridge type spindle are supported with 4 preloaded class 7 (P4) super precision angular-contact ball bearings, with the runout on the spindle nose being less than 0.0006 T.I.R.; ensuring quiet and vibration free operations for achieving better workpiece grinding accuracy;
7. Labyrinth seal on the spindle provides totally water-proof to protect the spindle's bearings, enlongating their services life;
8. Manual lubrications system provides lubrication to all moving mechanisms inclusive of the saddle guide ways, the column guide ways and the lead screws etc. for better grinding performance and less maintenance;
9. Convenient control panel includes all buttons and switches;
10. Digital readout system (two axis, Z-axis and Y-axis) are optional;
11. The minimum digital readout accuracy resolution 0.001-0.005mm;
12. Can be made to automatic-feeding type on all X,Y,Z axes on request.
