T2150 deep hole drilling machine
A), the basic process performance of the machine tool:
1 The machine can complete the drilling, boring, nesting and rolling of inner holes. During processing, the process of workpiece rotation, tool feeding, cutting fluid cooling through the oil dispenser (or boring bar) into the cutting area, lubrication, cooling the chip area, and wrapped chips to discharge chips forward.
2) When drilling, the chip removal process in BTA is adopted. When boring, the process of discharging cutting fluid and cutting chips forward (head end) is adopted.
3) Machining accuracy of the machine tool:
When drilling: hole diameter accuracy IT9-11. Surface roughness: Ra6.3.
During rough boring: hole diameter accuracy IT9-10. Surface roughness: Ra6.3. Zh
When fine boring: hole diameter accuracy IT8-9. Surface roughness: Ra3.2.
During rolling: Aperture accuracy IT8-9. Surface roughness: Ra0.4.
Straightness of processed hole: less than 0.15 / 1000.
The deviation of the outlet of the processing hole: less than 0.2 / 1000Processing efficiency of machine tools:
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 when boring: Determined according to the tool structure, material and workpiece conditions, generally not more than 30mm.
