Piston irregular pinhole boring machine
- Commodity name： Piston irregular pinhole boring machine
- Product Description
-
Features of the Piston Irregular Bush Boring Machine:The NP brand high-precision CNC irregular bush boring machine adopts an integral flat bed design with a rear-mounted chip removal system. The control system uses imported or well-known domestic brands (the system can be selected according to user requirements), with a variable frequency motor drive. The X and Z-axis drives use high-performance imported or domestically renowned brand original AC servo motors. The X and Z-axis movement of the machine tool uses Taiwan or domestic high-precision linear guide rails and high-precision ball screw pairs, resulting in good dynamic characteristics and high positioning and repeat positioning accuracy.The spindle assembly uses the NP series high-speed precision hydrostatic spindle unit independently researched and developed by our company. With an advanced sleeve-type design and a constant temperature setting, it boasts high precision, high speed, and strong rigidity. This machine is equipped with a precision fine-tuning servo boring device, suitable for the bush processing of various internal combustion engine aluminum and steel pistons, including rough machining and the fine machining of irregular bushes (oval, conical, curved holes). The size of the bush can be finely adjusted through program control. While processing the bush, fine-tuning compensation and spindle operation can occur simultaneously, enabling the creation of various specifications of irregular bushes according to customer drawings and maintaining product precision.
