- High-efficiency oil cooler：The high-efficiency oil cooler for the spindle effectively utilizes the recycling oil to take away the heat energy generated by the spindle running from the spindle through the refrigerating unit, so the spindle keeps operating at the normal temperature, thereby improving the machining precision, and ensuring the service life of the spindle.
- Tricolour light:The tricolour light is arranged at the conspicuous position of the machine. When the machine is out of order, the tricolour light gives warning to the operator.
- Automatic Lubricating System:The positive displacement point-to-point lubrication is used to ensure that the lubricating oil is filled into each oil inlet and uniformly distributed on the machine.
- Work light: One explosion-proof light is reasonably arranged on the two sides of the machine to fully ensure adequate lighting and protect the eyes from strong light.
- il-water separator: The oil-water separator separates the oil from the mixture in the event of oil-water mixing, and ensures the quality of cutting fluid. The recovered oil can be reused to save the cost.
- Laser tool setting gauge:The laser tool setting gauge can measure and detect the tool with the diameter as small as 0.003 mm at any point of the laser beam; the repeated accuracy can be ±0.1 μm in the specific environment; the level of protection is IP*8 in the rapid tool setting and breakage detection. (Continuous dive test)
- Manual tool setting gauge： High precision The manual tool setting gauge has the repeated positioning precision of 1μm, the direct driving contact mode and high parallelism, and can measure the small diameter tool.High leakproofness The manual tool setting gauge has the level of protection of IP67, is waterproof, oilproof and cutting fluid resistant, has good leakproofness and keeps high precision for a long time.
360-degree infrared transmission
Level of protection: IP*8
One-way repeated accuracy: 1.0μm
In the machine detection process, 90% non-cutting time is saved, and the process control is improved, so that the non-benefit tool setting and workpiece aligning time is shortened. The workpiece scrapping caused by the aligning error is eliminated. The workpiece is accurately detected to reduce the offline detection non-cutting time after machining.
- Energy-saving and environmentally friendly oil mist collector:It has high filter efficiency and statically filters; it is stable and reliable, and has high maintenance cost and low noise; it has high safety, no spark, no high voltage risk and vulnerable components; it can rapidly collect and capture the oil mist and dust and greatly improve the working quality of the machine.
