Stainless steel parts processing reaming process
Stainless steel parts Machining reaming process is as follows:
(1) tool geometry design stainless steel reaming most use of carbide reamer. Structural and geometrical parameters of ordinary reamer reamer different. To enhance the strength of the teeth and prevents clogging of chips when reaming, reamer number of teeth is generally relatively small. Stainless steel parts processing manufacturers tell you, before reamer angle is generally 8 ° ~ 12 °, but in certain cases, in order to achieve high speed reaming may also be used 0 ° ~ 5 ° rake angle; posterior horn is generally 8 ° ~ 12 °; the choice of different main angle varies depending on the hole, the through-hole is generally 15 ° ~ 30 °, blind hole is 45 °; when reaming forward in order to make the chip discharge, may be appropriate to increase the blade pitch angle , the blade pitch angle is generally 10 ° ~ 20 °; blade width of 0.1 ~ 0.15mm; the inverted cone reamer should be large compared with ordinary reamer, carbide reamer is generally 0.25 ~ 0.5mm / 100mm, high-speed steel hinge knife is 0.1 ~ 0.25mm / 100mm; reamer correcting section length is generally 65% to 80% of the ordinary reamer, wherein the cylindrical portion of the length of 40% to 50% of the ordinary reamer.
(2) Selection of Cutting reaming feed rate of 0.08 ~ 0.4mm / r, cutting speed is 10 ~ 20m / min, crude hinge margin is generally 0.2 ~ 0.3mm, fine hinge the balance 0.1 ~ 0.2mm. The crude hinge should use carbide tools, high speed steel cutting tools can be fine when the hinge.
(3) stainless steel parts processing manufacturers tell you, when the cutting fluid selection of stainless steel reaming, can be used system-wide loss oil or molybdenum disulfide as a cooling medium.
