The main performance characteristics: 1. The machine has reasonable structure, good rigidity, beautiful appearance, convenient operation. 2. Worktable ball track using steel materials for high precision steel balls, abrasion resistance, easily moved and labor saving, and can be greatly improve work efficiency. 3. Former after skidway through careful scraping flower, not only slide smoothly, and wear-resisting, maintain good accuracy, flexible and convenient operation. Manual worktable driven by synchronous belt transmission, wear well. 4. The spindle adopts super precision ball bearing P4, after strict selection after the pre pressure measurement, assembled in the greenhouse, and with the labyrinth design completely waterproof, In order to ensure the service life of the bearing and the grinding surface roughness. 5. No vibration, low noise motor spindle. 6. According to the needs of users with a permanent magnet sucker or electromagnetic sucker.
