CNC Control Deep Hole Skiving Roller Burnishing Machine

TGK25S CNC Deep Hole Skiving Roller Burnishing Machine – Main Functions

The TGK25S CNC deep hole skiving roller burnishing machine is built for deep hole part production. This CNC deep hole skiving roller burnishing machine handles boring, skiving, and roller burnishing in one setup. It is a compound design for hydraulic cylinders, spindle bores, cylinder bores, and cooling channels. Workpiece bore accuracy reaches IT7–IT9. Surface finish after roller burnishing falls between Ra0.05 and 0.4 μm.

All castings use a box-type structure. Finite element analysis guides the design to balance mass, stiffness, and precision. High-strength cast iron and resin sand molding are standard. Every casting receives normalization after pouring to release internal stress. After rough cutting, a second normalization cycle removes both residual cast stress and machining-induced stress. This two-step treatment ensures long-term dimensional stability.

Machining Modes and Chip Evacuation

This CNC deep hole skiving roller burnishing machine offers three cutting modes:

Workpiece and tool rotate in opposite directions, with tool feed.

Workpiece rotates, tool stays fixed, and feed is applied.

Workpiece remains stationary, tool rotates and feeds.

For rough passes, a push-boring head does the heavy cutting. For finishing, a combined skiving and roller burnishing tool (hydraulic or pneumatic) does the final work. This setup corrects the deflection often seen in hot-rolled steel pipe rough boring. It also improves straightness after cold-drawn pipe finishing, which typically suffers from poor alignment.

Process Selection

When the hot-rolled pipe bore ranges from Φ80 mm to Φ250 mm, the CNC deep hole skiving roller burnishing machine uses a hydraulic boring-skiving-roller tool to complete rough boring, skiving, and burnishing in one pass. For cold-drawn pipe bores from Φ38 mm to Φ250 mm, a pneumatic or hydraulic skiving-roller tool handles the entire operation in a single pass. This flexibility makes the CNC deep hole skiving roller burnishing machine suitable for a wide diameter range with consistent results.
