T2125 deep hole boring machine
I. basic process performance of machine tool:
1) drilling, boring, expanding and rolling of inner hole can be completed in this machine tool.
2) when machining, the workpiece rotates or the tool workpiece rotates at the same time, and the tool feeds to complete the cutting movement.
3) with cutting fluid filtration system.
4) machining accuracy of machine tool:
Drilling: hole diameter accuracy it10. Surface roughness: ≤ ra6.3 μ M
Coarse boring: aperture accuracy it10. Surface roughness: ≤ ra6.3 μ M.
When finishing boring: aperture precision it8. Surface roughness: ≤ ra3.2 μ M. Roundness: ≤ 0.03mm.
When rolling: aperture precision it8. Surface roughness: ≤ Ra0.4 μ M. Roundness: ≤ 0.03mm.
Straightness of machining hole: ≤ 0.15/1000mm.
5) 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 workpiece processing diameter, workpiece material, heat treatment status and process conditions, generally 40-100mm / min.
Maximum machining allowance during boring: it is determined according to the structure, material and workpiece of the tool, generally no more than 20 mm.
