1.The spindle is driven by a built-in motor. In order to reduce vibration, the spindle must be dynamically balanced after being loaded into the rotor. The center of gravity offset must not exceed 3.5μ, and the grinding wheel must be statically balanced. 2.The distance between the oil recovery point and the oil entry point in the oil pool is the longest, and the hydraulic oil is circulated to balance the oil temperature distribution and reduce the thermal deformation of the machine. 3.Adopt famous brand hydraulic parts, make sure stability of movement and reliable reversing action. 4.This machine tool has beautiful shape, good rigidity, stable and reliable performance and easy to maintenance. 5.According to customer's need, can choose inverter driven on wheelhead cross movement, realize stepless speed adjustment. 6.Integrated central operation panel and clear logo, simple and easy to operate. 7.Optional magnetic separator and paper tape filter to reduce the dust of the cutting liquid and ensure the grinding process. 8.Optional external hydraulic station eliminates the influence of oil temperature rise on the machine tool and improves machining accuracy.
