        Technical Parameter

        I. basic process performance of machine tool:

        The machine tool is a deep hole equipment which is specially used for heavy-duty workpiece inner hole processing. The machine tool can complete the drilling, boring, expanding, rolling and nesting processing of the inner hole; the boring rod is used to supply the cutting fluid to discharge the cutting fluid and iron chips to (the head end of the bed). According to the user's requirements, the machine tool can be equipped with a drilling (boring) rod box to increase its drilling and cutting functions. The BTA internal chip removal process is adopted when drilling; the workpiece can rotate at a low speed, and the cutter can rotate at a high speed and feed back and forth to improve the processing efficiency.

        The diameter of the inner hole of the workpiece processed by the heavy-duty deep hole boring machine can reach φ 800mm, and the length of the workpiec can reach 16m.

        Machining accuracy of machine tool:

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

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

        Straightness of machining hole: ≤ 0.15/1000mm.

        Outlet deviation of machining hole: ≤ 0.5/1000mm.

        Machining efficiency of machine tool:

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

        Feed speed: it is determined according to the processing conditions and process conditions, generally 10-100mm / min

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