T2150Deep hole boring machine

hot sale of T2150x3m deep hole drilling and boring machine




I) basic process performance of machine tool:


1) drilling, boring, trepanning and burnishing of inner hole can be completed in this machine tool. During machining, workpiece rotation, tool feeding, cutting liquid  enter into the cutting area, lubrication, cooling chip area through the pressure head(or boring bar), and the  chip is discharged forward.


2) the BTA internal chip removal process is adopted during drilling. When boring, the cutting fluid and chips are discharged forward 
 
 
3) machining accuracy of machine tool:


Drilling: hole diameter accuracy IT9-11. Surface roughness: Ra6.3.


Counter boring: aperture precision IT 9-10. Surface roughness: Ra6.3.


Precision boring: aperture precision IT 8-9. Surface roughness: Ra3.2.
 
 
Burnishing: aperture precision IT8-9. Surface roughness: Ra0.4.


Straightness of machining hole: less than 0.15/1000.


Outlet deviation of machining hole: less than 0.2/1000


Machining efficiency of machine tool:


Cutting speed: determined according to the tool structure, material and workpiece material, generally 50-100m / min.


Feed speed: determined according to the processing conditions, generally 40-100mm / min.


Maximum stock removal during boring: it is determined according to the structure, material and workpiece of the tool, generally not more than 30mm.
