Changzhou Jier Precision Machinery Manufacturing Co., Ltd. uses CNC machining centers to achieve high-speed precision drilling and processing, which can be customized according to customer needs. The maximum processing range is 2000 * 2200mm, and the minimum hole diameter can be drilled and processed to 0.06mm ± 0.002mm. The verticality of the processed hole is within 0.02. There will be no phenomena such as elliptical or conical holes (large on top and small on the bottom), ablation hardened layers on the surface of the holes, and poor surface finish of the holes processed by electric discharge or laser.
