CNC Deep Hole Skiving Roller Burnishing Machine

Machine overview

      TGK20S CNC deep hole skiving and roller burnishing machine is an ideal machine for processing deep hole parts. It integrates boring, skiving and burnishing, and is a machine specially designed for compound processing. This machine is suitable for processing various hydraulic cylinders, spindle holes, cylinder holes, and cooling holes.

The accuracy of the hole size of the processed parts can reach IT7~IT9, and the surface roughness of the inner hole: Ra0.05~0.4μm.

      All casting parts of the machine are made of high-strength cast iron and resin sand casting. All castings are normalized after casting to eliminate the internal stress generated during the casting process. After rough machining, normalizing treatment is performed again to further eliminate the internal stress generated during the casting process, and at the same time remove the processing stress generated during the rough machining, so that it has good accuracy stability.

 

Main parameters (Customization available):
Processing hole diameter range: Φ38~Φ200mm
Max. processing depth: 3000mm
Workpiece OD range: Φ50~Φ350mm
Workpiece length range: 500~3000mm

 

Machine processing method

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.

Rough machining: use the rough boring head to do push boring processing.

Fine machining: use skiving and burnishing (hydraulic or pneumatic) combined cutting tool to process, effectively reducing deviation after rough machining of hot-rolled steel pipes and poor straightness after fine processing of cold-drawn steel pipes .

 

Main parts of the machine

Machine overall layout: Machine bed, Headstock , workpiece roller carrier, workpiece carrier, oil pressure head, boring box, boring bar support rest, feeding system, cooling system, CNC control system and so on.

Machine bed

Machine is equipped with rectangular guide rails, which have been quenched and have high wear resistance; the bed adopts a split structure, which is assembled with high-strength bolts and is positioned with tapered pins.

Headstock :

The headstock is located at the left end of the bed, used for driving the workpiece to rotate. The headstock is driven by the main motor through the belt to rotate the spindle to realize speed stepless adjustment and meet the processing requirements of each diameter of hole.

Oil pressure head:

The oil pressure head is the core component of the deep hole machine, which is used for guiding the cutting tool , supply cutting oil , supporting boring bars, and workpiece positioning.

Boring box:

The boring box is fixed on the feeding carriage for driving the tool to rotate and feed. The motor of boring box drives the spindle to rotate through the belt and gear.

Coolant system:

The main function of the cooling system is to use the circulating liquid medium to lubricate and cool the cutting area and remove the cutting chips. The cooling system adopts an above-ground oil tank structure. The cooling oil take away cutting chips by the chips conveyor and then filtered through a three-stage filter as filer mesh (rough filtering)-magnetic filter-Fine filtering. The filtering accuracy can be 50μm.
