Details and advantages

1. The precision linear rolling guide and high precision inclined rack on the machine bed are arranged horizontally. The rack is installed between the two guide rails, and the mobile column is installed on the machine bed.

2. There are 8 CNC axes and 2 servo spindles in the machine tool. Each CNC axis is guided by precision linear rolling guide. The x-axis is driven by AC servo motor through precision ball screw. Double nut pre-tightening structure is used in the ball screw, which can eliminate the axial back clearance and reduce the elastic displacement caused by the axial force. There is no clearance in the movement, and the host machine has a separate magnetic grid ruler detection system in the X and Y axis movement of the bed, which can ensure the positioning accuracy of coordinate movement;

3. The machine has the function of laser end Searching and locating the origin, which is convenient for tool processing and improving the processing efficiency. The repeatability of laser alignment device is less than 0.2mm. It also has the function of rail length detection, which can detect both ends of the rail through the laser switch, so as to detect the length of the rail. It can recheck the incoming materials and reduce errors.

4. The drilling tool is a molding tool. The drilling and front chamfering are completed at one time. The tool is made of Transposition carbide blade, and the spindle is cooled by air mist. There is a chamfering head on the reverse side for chamfering, and the chamfering tool is also of carbide blade type structure. This chamfering tool has a large chamfering range and does not need to change the tool during processing.
5. Siemens 828d CNC system is used in the CNC system, which can monitor the drilling process in real time. It can recognize the two-dimensional code and call the machining program.
