(1) The electrical design fully complies with CE standards. The use of imported cables effectively reduces the impact of electrical interference, while also adopting
Using European circuit design and manufacturing standards, the electrical appliances are stable and easy to maintain.
6. Tool cooling system
(1) The tool cooling system adopts an external circulation method, and the coolant flows into the chain plate elevator at one end of the bed through the spiral chip removal groove on both sides of the bed. After filtration and separation, the coolant flows into the coolant box on the elevator, and then is transported to the cooling nozzle at the spindle position by the coolant electric pump.
7. Smooth chip removal system
(1) The machine tool bed is equipped with spiral chip conveyors on both sides, which can transport the processed iron chips to the chain plate lifting device at the front end of the machine tool bed. The lifting device is equipped with a cutting fluid water tank, which is equipped with a high head coolant pump. The high head water pump transports the purified cutting fluid to the end of the spindle, which has multiple cooling nozzles. The cooling nozzles spray the cutting fluid onto the tool to cool it. The debris is collected by the elevator and transported to the recycling truck.
8. Lubrication of machine tool guide rails
(1) The lubrication of each axis guide rail adopts a central integrated self timed quantitative lubrication system, which is automatic lubrication and may experience pressure loss
And oil shortage safety protection.
9. Protection form
(1) The X-axis guide rail of the machine tool is protected by a stainless steel telescopic protective cover.
(2) The Y-axis guide rail of the machine tool is protected by a telescopic organ protective cover.
(3) Install maintenance ladders and protective railings on the gantry frame.
(4) The X, Y, and Z axes are equipped with drag chain protection devices.
