Features:1.Replace skilled technicians: lead column in sets industry completely replace the skilled senior operating technician drilling, just ordinary workers, the machine is turned into the workpiece, the machine will operate automatically.2. Can be processed products of many varieties: users can set by the machine interface, a flexible set of machined parts and drilling path.3. Product quality is stable, reliable device uses advanced CNC technology to ensure the accuracy of product processing and the unity of the same product, especially in the guide pins and bushings processing sectors, not like the artificial drilling, due to the different personnel and other factors affect product uniformity and precision. 4. To reduce manpower costs.
