Piston irregular pinhole double-head boring machine
- Commodity name： Piston irregular pinhole double-head boring machine
- Product Description
-
Features of Piston Irregular Bush Boring Machine:The NP brand high-precision CNC irregular bush boring machine adopts an integral flat bed design and rear-positioned chip removal. The control system uses imported or domestic well-known brands (the system can be optionally configured according to user requirements), with variable frequency motor drive. The X and Z-axis drives use high-performance imported or domestically well-known brand system-original AC servo motors. The X and Z-axis movements of the machine tool use Taiwan 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 static and dynamic pressure spindle unit independently developed by our company. The advanced sleeve-type design sets a constant temperature state, achieving high precision, high speed, and high rigidity. This machine is equipped with a precision fine-tuning servo boring device, suitable for processing the bush holes of various internal combustion engine aluminum and steel pistons. It handles both rough machining and precision machining of irregular bush holes (oval, tapered, curved holes). The bush hole size can be finely adjusted through program control; while processing bush holes, fine adjustment compensation and spindle rotation can occur simultaneously. Various specifications of irregular bush holes can be produced according to customer drawings, ensuring product accuracy.
