● The main shaft gearbox achieves a larger speed range and torque through two-speed mechanical shifting. The internal gears of the gearbox adopt Taiwan's 5th grade precision cylindrical gear transmission, which has smooth transmission, low noise, impact load resistance and very high transmission stiffness. ability. The reduction ratios of the low-speed gear and high-speed gear of the gearbox are: 1:3.11 and 1:1.02 respectively.
● The machine tool is equipped with a constant-temperature oil cooler as standard: 1. To prevent the temperature of the bearings and gears from rising too high during operation. The constant-temperature oil cooler can be adjusted according to the climate in different areas to ensure the working accuracy of the machine tool and normal operation at each room temperature; 2. Fully lubricate the bearings and gears, reduce wear and noise, and extend service life.
● Double spiral
● Spindle box balance: nitrogen balancing cylinder
