Deep hole drilling and boring machine

Product Overviews

According to length of workpiece, This machine has two choice in production: one is feed by grant oiler and hydraulic pressing for short workpiece, the other is feed by end of boring bar ,and fixed by four chuck jaw for long workpiece. The grant oiler is new spindle structure which has better load-bearing and rotate precision. The bed is double square rails,and it is better load ability and good precision. The rail passed quench process which makes it more abrasive. It can be used in boring and rolling production of machine,vessels,hydraulic,power machine,and air machine.The surface roughness can reach Ra 0.4µm. Cutter feeding is servo driving system and stepless speed regulation. 

You can choose the following style for different workpiece:

1,workpiece rotating,cutter rotating and repeat feeding

2,workpiece rotating ,cutter no rotating but only repeat feeding 

3,workpieces don't rotate,but cutter rotates and repeat feeding

Basic technology and performance

1,it can drill,boring,expand and roll

2,when producing,the workpiece is rotating,cutter feeding,then the cutting fluid goes into cutting area to cool and lubricate the cutting area ,and take out clastics 

3,it uses BTA to take out all clastics.When boring,cutter fluid is supplied inside boring bar and it is discharged forwardly.

4,you can install drilling and boring box if need to rotate cutters.This can decrease speed  of  workpiece,increase efficiency and get better quality.

5,  precision

Rough boring:hole dia precision is IT9-10.surface roughness is Ra6.3um

Refined boring:hole dia precision is IT8-9.surface roughness is Ra3.2um

Rolling :hole dia precision is IT8-9.surface roughness is Ra0.4um

Straightness of the hole:less than 0.15/1000mm

Outlet angle of the hole:less than 0.5/1000mm

6,production efficiency 

Cutting speed:according to cutter's structure and material and workpiece material,it is 50-100m/min usually

Feeding speed:according to real situation,it is 20-100mm/min usually

Max boring production margin:according to cutter's structure and material and workpiece material,it is no more than 30mm usually
