Dezhou Guanlu Precision Machinery Co.,Ltd
TGK series CNC deep hole skiving roller burnishing machine is suitable for boring, scraping, rolling and combination processing of various hydraulic cylinders,cylinders and other precision pipe fittings. if customer has the requirement of drilling function ,it is also possible. The processing aperture accuracy can reach IT8~IT10, and the surface roughness can reach Ra0.05-0.4μm after rolling.


This machine is the substitution for deep hole drilling and boring machine,it is combined the rough boring、 precise boring and burnishing process together,by using the special SRB tools(forward is for skiving process and backward is for rolling and burnishing process),one time could work out hole roughness to Ra0.05um-Ra0.4um.

CNC controller: Siemens/Fanuc/GSK
SRB machine application industry:hydraulic cylinders,industry cylinders,piston and so on.

S

Mainly structure of Guanlu SRB machine:
Machine bed:
Machine is 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.
A high-precision ball screw pair is installed at the right end of the bed for the movement of the boring box (Z1 axis). The ball screw pair is used for the feeding of machine, which has the advantages of smooth transmission, high transmission efficiency, and high precision.


Headstock frame
The head frame is located at the left end of the bed, the hydraulic system drive the spindle inside of head frame to move for tightening the workpiece.
A cone disc and a guide sleeve are installed at the right end of the headstock . The cone disc is used for workpiece positioning and tightening, and the guide sleeve is used to support the cutting tool after machining finished.
A chips removal bucket is installed at the left end of the head frame to transfer the cutting chips and cooling oil into the chips conveyor .

Workpiece carrier and hydraulic clamping device
The workpice carrier is used for auxiliary support of the workpiece, which is convenient for workpiece clamping, and its working position is slightly lower than the workpiece clamping position. The carrier can be raised and lowered manually to meet the support of workpieces with different OD.
The hydraulic clamping device is used for clamping the workpiece .The clamping frame uses the hydraulic motor to clamp the workpiece through the trapezoidal screw, which has the function of self-centering. Workpiece clamping is completed after workpiece tightening, and the clamping sequence can be adjusted manually.

Oil pressure head
The oil pressure head is the core component of the deep hole machines, which is used for guiding the cutting tool , supply cutting oil , supporting boring bars, and workpiece positioning.There is a cone disc mounting in front of the oil pressure head, which is used for positioning and tightening the workpiece. It is combined with the workpiece at a cone angle of 60°. The taper is customized according to the needs of the workpiece. The oil pressure head can be moved to adapt to the processing of workpieces with different length.

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 synchronous belt. The front end of the spindle is equipped with a boring bar clamping sleeve for clamping the boring bar.
The bearing of boring box is lubricated by an independent lubrication system to circulate the lubricating oil.
Boring bar support rest:
It is used to support the boring bar, and a support sleeve is mounted on it, which can absorb the impact and jitter generated during the processing.

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 (rough filter)-magnetic filter-cloth bag fine filter.
