T2150 deep hole boring machine

I) basic process performance of machine tool:

1) drilling, boring, nesting and rolling of inner hole can be completed in this machine tool. During machining, workpiece rotation, tool feeding, cutting liquid cooling enter into the cutting area, lubrication, cooling chip area through the oil feeder (or boring bar), and the wrapping 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 (head end).

3) machining accuracy of machine tool:

Drilling: hole diameter accuracy it9-11. Surface roughness: ra6.3.

Coarse boring: aperture precision it9-10. Surface roughness: ra6.3.

Precision boring: aperture precision it8-9. Surface roughness: ra3.2.

Rolling: aperture precision it8-9. Surface roughness: Ra0.4.

Straightness of machining hole: less than 0.15/1000.

Outlet deflection 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 machining allowance during boring: it is determined according to the structure, material and workpiece of the tool, generally not more than 30mm.
