The workpiece material is Q345D, is the whole hard alloy reamer diameter 18 6 blade laevorotatory right edge reamer, now found out the hole hinge inside there is always a circle cut, when processing the machining allowance for unilateral 0.2mm, reamer speed 120r/s, feed rate is 45mm/min, the cooling liquid is emulsion, which can master under the guidance, the argument is correct. It's better to give a machining parameter, s and F, thank you. The tool is added to several beds, beating about 1 wires.
Speed can be fed too fast, suggest speed 120, feed 6 to 10, if you can margin, as far as possible less unilateral 0.1 on the line. I have also been out of this problem, that is how to solve it, as well as the quality of the tool is also critical, ah, you tried to adopt Oh.
For you the double-edged cutter, S and F on the line four pin gear extrusion
Do you use G81 or G85 or G01 feed?
