| JG850H Series |
|
JG850H Series Vertical Machining Center |
|
|
|
FEATURES: |
| ◆ The pre-tension precision angular contact ball bearings imported from abroad, offer maximum rigidity and precision of spindle. Main spindle adopt AC servo or inverter unit, so spindle with high rigid and little vibration. |
| ◆ Ballscrew adopt super long high precious C3 grade double nuts preloaded, this ensures high positioning accuracy and reliability |
| ◆ With special guideway seat design, narrow guide distance, wide guide face, supporting on whole travel range, sliding guideways series machining center have the advantages of no overhang, strong load and larger torque cutting, also coated with wearable TURCITE-B fluorin resin plastics, and presious scratch and grind by hand, make axes smoothly motion and machine have unvarying precision. |
| ◆ RENISHAW double frequency laser interferometer is used to test the positioning accuracy and repeatability of machine and ensures high precious pitch compensation and backlash compensation. |
| ◆ Important elements and test pieces cut on the machine are tested by BROWN & SHARPE 3D coordinate measuring machine. |
| ◆ Sliding guideway series machining center have wide guideway and good loading capacity, they are suitable for high rigidity, high precision and high efficiency machining occasions. | |
|
◆ Positive-displacement timing and rationing centralization lubrication system is used. This ensures every oil site is lubricated with sufficient oil. Bothe oil low level buzzer and PLC give warning signal reminding the operator of adding lubricant. |
| ◆ Large power, large capacity and high lift coolant pump ensure sufficient cooling and effective chip flushing (optional) | |
