In metallic cutting treatment, can come up against library of CNC machine tool sometimes insufficient, a cutting tool perhaps can be installed only above private plane, finish a variety of cutting jobs, at this moment functional compound cutting tool can be sent on use, ovation. Antimonial Ma tool is quite intentional to this, in the function compound or one knife is multi-purpose go up to go out to be tasted newly repeatedly, for example is gotten + mill (contain whorl) , auger + bore with a reamer, auger + attack, mill + bore with a reamer, mill + mill whorl, attack + attack wait a form a moment, emerge in endlessly, solved a lot of difficult problem for the client. The function is compound cutting tool, although the advantage is clear, but be designed to cutting tool and be being made is a challenge. General function is compound cutting tool, or blade grows to want to grow than common cutting tool, or increases the function of cervical structure or retrorse cutting. Such word, bring about cutting tool tigidity to drop on one hand, on the other hand, the production difficulty of cutting tool and cost also can rise. So functional compound cutting tool, be compared to be in by the long way of the spare parts of treatment less than of 2 times diameter is advisable. Lie add private plane to machine spare parts [case is shared] we have a client, following plan institute show the part, there are 6 apertures to need to machine on flank, among them round hole of D13mm of 4 Kong Wei, 1 is D35 large hole, still have a breadth for 21. The waist of 5 aperture, hole depth is 8mm, via, besides D35 Kong Youyu aperture, all sincere machines the others. The machine tool is horizontal private plane, without knife library, odd main shaft, can install a cutting tool only. The client machines efficiency to rise, entrust us to design compound cutting tool for its, finish the cutting of 6 aperture namely with a knife. Very apparent, the aperture of D13 can use broach to finish, but the large hole of D35 needs milling treatment, ability of the mill after waist aperture need is gotten first is finished, cutting tool needs the form of the mill after before the design is become, be being gotten, in the meantime, place of a flight of stairs needs to have cutting function. The spare parts machines content (6 aperture) get mill graph of effect of compound knife design processes data: 45# steel HB217-235 machines equipment: Form of refrigeration of horizontal private plane: Leng Ga maintains pattern outside: Rotate speed of BT40 puissant knife handle: 1550rpm feed: Get 0.
