我厂制造的校直模,需要加工长度在300～700mm,直径在φ27～φ33之间的半圆孔。过去,一般采用镗孔或用两面刃成型立铣刀加工。由于半圆孔的孔径小,又比较长。所以,采用上述两种加工方法都达不到埋想效果。针对以上情况,我们设计了一把刀头可绕轴转动的硬质合金机夹盘铣刀(图1).改在卧式铣床上加工。该盘铣刀由盘刀1、定位芯轴2、刀头3、螺钉4和楔块5组成,刀片材料选用适合加工淬硬钢的 YW 类硬质合金。使用时,可根据待加工孔径的大小选用外径 D
Straightening mold I plant, need to process the length of 300 ~ 700mm, the diameter of φ27 ~ φ33 between the semi-circular hole. In the past, the general use of boring or milling cutter with two edges. As a semi-circular hole aperture, but also longer. Therefore, the use of these two processing methods are not buried effect. In view of the above situation, we have designed a cutter head can rotate around the carbide machine chuck cutter (Figure 1) Change in the horizontal milling machine processing. The disc cutter consists of a disc cutter 1, a positioning mandrel 2, a cutter head 3, a screw 4 and a wedge 5. The blade material is made of YW carbide suitable for processing hardened steel. Use, according to the size of the aperture to be processed use diameter D
