Function Description
When processing. the workpiece is fixed and the cutting tool is rotated. Adopting the combined technology of skiving and roller burnishing, the machine gives a good solution for the severe deviation in rough processing of hot roller steel pipe, and the inferior straightness in fine processing of cold drawn steel tube. It is mainly used for the compound process of boring and roller burnishing for hydraulic cylinder parts. The hole tolerance is up to IT7-8, the surface roughness is up to Ra0.2-0.4μm. its processing efficiency is 10 times of the traditional boring technology and 20 times of ordinary honing machines. The traditional technology usually includes four independent steps in order: rough boring-semi finish boring-floating boring-roller burnishing, which is inefficient and needs a long time.
This machine is assembled with automated flexible tools control module, using the specialized Korean pneumatic and Germany hydraulic tools system, the processing allowance 0.2-8mm in radial direction is available.
TGK series machines adopt Siemens 808 CNC system (optional), the headstock spindle is driven by AC variable frequency motor, with stepless speed regulating. The bed body adopts high quality cast iron, the double flat guide way ensures the good rigidity and excellent guiding. And protection guard structure is equipped around. The machine has the automatic chip conveyer, magnetic separator and paper filter. Filtering precision is up to 20μm. The coolant can be cleanly recycled and reutilized.
Note：If the customer’s workpiece is hot-rolled pipe, we can also install a headstock according to the customer’s needs, so that the workpiece and the tool can rotate at the same time.
