Technical Parameter
 

Basic process performance of machine tool:




1) drilling, boring, expanding and rolling of inner hole can be completed in this machine tool.




2) during machining, the workpiece rotates and the cutter feeds, the cutting fluid enters the cutting area through the oil feeder, cools and lubricates the cutting area and takes away the chips.




3) the BTA internal chip removal process is adopted during drilling. When boring, adopt the technology of cutting fluid supply in the boring bar to discharge cutting fluid and chips forward (head end).




4) according to the needs of processing technology, the drill and boring bar box can be installed, and the cutter can rotate. Reduce the rotating speed of the workpiece, improve the processing efficiency and ensure the processing quality.




5) machining accuracy of machine tool:




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: Ra0.2.




Straightness of machining hole: less than 0.15/1000mm.




Outlet deflection of machining hole: less than 0.5/1000mm.




6) 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 20-100mm / min.




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