This machine is the substitution for deep hole boring machine,it is combined the rough boring and precise boring 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.

Working range: 38mm-500mm(variously models in between),please advise your hole diameter and we will recommend you the right model.

Dezhou Guanlu SRB machine had two types,one is TGG series,whoes cut value is 6mm,we called it heavy duty SRB machine. The other type is TGK series,whoes cut value is 0.5mm. It is standard type SRB machine.

Function of the SRB machine:Solid drilling,skiving roller and burnishing.

Dezhou Guanlu skiving roller burnishing machine advantages: 

Absorbing advanced structure of Japanese and Korean famous brand,exported to several European countries such as France,Germany,Italy.

Applicable for processing the hot-rolled pipes and cold drawn pipes, specially used for hydraulic cylinders industry.

Auto loading and unloading system is optional.

Hole ID range: 38-800mm(many models are optional)  

Max. Processing depth :20000mm 

2-5times higher efficiecy than traditional deep hole drilling and boring machine

Saving labour cost.

Get harder inner hole surface

Low noise,no pollution.

SRB tools is produced by our own factory,it is long life span and with attrative price.

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.

Details about Guanlu and Guanlu Brand deep hole honing machine.

Dezhou Guanlu Precision Machinery Co.,Ltd,is founded in year 2011,we are the most famous factory in my local to manufacture deep hole drilling machines,deep hole skiving roller burnishing machines.. My city Dezhou is the production base of deep hole machines in China. 

We have our own strongly machining facilite, Germany brand Heckert guide grinder,Japanese SNK five face milling center ,chinese most famous planner,VMC,Lathes,box boring machine,milling machine and so on. With these good machning facility,we could be able to manufacture the best quality and best accuracy deep hole machines,under proper management system,we could orgnize production properly,our delivery of machines are stable and in time,we also have some regular models stocks.

Our deep hole drilling machine has been exported to more than 50 countries and gained good reputation and fame. We improved our quality and structure day by day. 

DZ Guanlu FACTORY advantages compared with other competitors:

Our city is the production base of deep hole drilling and boring machines. Among these local competitors,our company is the first choice once clients has visited us and saw our deep hole machines. we have the absulately advantages than others.

Big workshops and Big factory: we have four workshops,one commercial office building and totally 70000square meters working area.
