CNC Deep Hole Skiving And Rolling And Burnishing Machine

TGK40S CNC deep hole skiving rolling and burnishing machine 

 

an ideal machine for machining deep hole parts. The machine combines boring,skiving and rolling machining in one, and it is a machine designed for compound machining. The machine tool is suitable for machining various hydraulic cylinders, spindle holes, cylinder holes and cooling holes. The dimensional accuracy of the hole diameter of the machined parts can reach IT7~ IT9, and the surface roughness of the inner hole after rolling: Ra0.1~0.4 μ m.

All castings of machine tools adopt the design concept of box structure, and are optimized by finite element analysis, so that they have the characteristics of reasonable quality, high rigidity and high precision.

All castings of the machine tool are made of high-strength cast iron and resin sand molding casting. All castings are normalized after casting to eliminate the internal stresses generated by the castings during casting. After roughing, normalization is carried out again to further eliminate the internal stress generated in the casting process, and at the same time, the machining stress generated during roughing is removed, so that it has good accuracy and stability.

 

CNC deep hole skiving rolling and burnishing machine tool processing and chip removal methods:

The machine has three working modes: ①Workpiece and cutting tool rotate in opposite directions, cutting tool feed ; ②Workpiece rotate, cutting tool fixed and feed ; ③Workpiece fixed, cutting tool rotate and feed . The rough boring head is used for push boring during rough machining, and the SRB head (hydraulic or pneumatic) is used for finishing machining, which effectively solves the problem of serious deviation in rough machining of deep holes of hot-rolled steel pipes and poor straightness after finishing of deep holes of cold drawn steel pipes.

Pneumatic skiving and roller burnishing tool: skiving and roller composite tool, which adopts push boring, pull rolling, oil supply by oil pressure head , and chips are discharged forward through the inner hole of parts.

Hydraulic skiving and roller burnishing tool: skiving and roller composite tool, which adopts push boring and rolling, oil supply by oil pressure head , and chips are discharged forward through the inner hole of parts.

Boring and rolling: Push boring and rolling, oil is supplied by oil pressure head, and chips are discharged forward through the inner hole of the parts that have been processed. Push boring and rolling are machined separately, which is suitable for machining small holes without compound tools.
