CK6140 high-precision CNC horizontal lathe

Main Parts Introduction

1、Bed.
Adopting flat bed structure, resin sand molding, high quality cast iron casting, guide rail adopts medium frequency quenching and grinding and pasting molding process, which has good abrasion resistance and precision keeping.
2、Spindle box.
The spindle structure adopts the typical structure of two-point support at the front and rear ends, and the spindle has high rigidity; the bearing adopts the special bearing for a high-precision spindle of Harbin Bearing Factory, which makes the spindle have high rotary accuracy. The main drive speed range is 100~2000r/min; the main drive gears are hardened and ground, the drive, and rolling bearings are lubricated by strong oil, with good high-speed and low-temperature rise performance; the design of the spindle box case takes into full consideration of the heat dissipation measures and vibration-damping mechanism, which makes the spindle box have the features of low noise and high transmission accuracy, and the noise of the machine tool does not exceed the value stipulated by the national standard. The noise of the machine does not exceed the value stipulated by the national standard. The machine has an electrical overload protection device, a mechanical overload protection device, and an emergency stop device to control spindle rotation. The automatic speed change machine type is equipped with an external automatic speed change control box.
3. Feeding motion
The transverse (X-axis) and longitudinal (Z-axis) feeding movements are driven by servo motors to realize the rapid traverse and feeding movements with precision ball screws.
The slide guideway is affixed with an anti-creeping plastic soft belt, which can well guarantee the positioning accuracy and repeatability of the machine tool.
4. Tailstock.
The design of the tailstock of the machine gives full consideration to the rigidity, loading capacity, and user-friendliness. The tightening method is manual.
6. Chuck
The machine is equipped with an 8-inch three-jaw chuck (optional hydraulic).
7. Centralised lubrication
Adopting Japanese technology centralized lubrication system to realize the lubrication of each guide rail, ball screw, and bearing. The lubrication pump has the functions of working status display and hydraulic monitoring. And can be adjusted at any time oil injection cycle.
3、Numerical control tool holder
Vertical four-station CNC tool holder has the features of high positioning accuracy, stability and reliability, a wide range of applications, simple structure, easy maintenance, and so on.
4、Working environment of machine tool
Ambient temperature:5℃~40°℃ range and the average temperature of 24h does not exceed 35℃.
Relative humidity: 30%~95% and the principle of humidity change is that it should not cause condensation.
Altitude: below 1000m.
Atmosphere: no excessive dust, acid gas, corrosive gas and salt.
Avoid direct sunlight on the machine or heat radiation on the machine that may cause changes in the ambient temperature.
Installation position away from sources of vibration.
Installation position away from flammable and explosive materials.
