The target that the grand chamfer form of the cutting blade that graph 1 CoroDrill 870 can change head bit and small chamfer form improve process capability and performance a new standard to develop new generation to be able to change head bit is to be so far still not antiquated can change all sorts of a broach, twist drill, shovel auger. The use that can change head bit is representing the newest progress of cutting tool. It can be the aperture inside very big range auger cut offer a lot of advantage, also be accordingly in cutting tool treatment establish favorable position. Generally speaking, can change head broach to be able to enclothe what be combined by aperture diameter limits and tolerancepublic errand limits and become the area intermediate. Although can change head broach to already had a lot of advantages, but face current world cutting to machine increasingly intense competition, to can changing the requirement of head broach must further, with satisfying treatment requirement better. Broach has different capacity the broach of different type, for example broach of integral hard alloy, but broach of dislocation razor blade or it is to be able to change head bit, they have different process capability. According to the ceaseless development of the requirement to aperture, actual limitation to cutting tool and cutting tool, different broach has respective and applicable application range. Current, the broach dominant of these types aperture machines a domain, this treatment domain is comprised by all sorts of element domains again, the molecular domain development as broach and applicable ability and change somewhat. The type of aperture has a lot of, it is 12~30mm to aperture diameter limits, hole depth is 3~5 the aperture treatment of times diameter still is had very big improve latent capacity, mix in life of function, security, cutting tool especially the respect such as aperture quality consistency. Typical opening is to attack whorl aperture, cut for bore with a reamer beforehand the craft aperture of the tube plate aperture on aperture, heat exchanger, tall nicety and deeper aperture. These aperture have to nod jointly: Normally tolerancepublic errand limits is IT9~10, this needs outstanding broach precision. Extensive to limits of this kind of application but the treatment with tolerancepublic errand very strict requirement, very tall to the requirement of cutting tool. And the restriction that the model that can change head bit and structure have practice and ability side, for example function of card of outfit of the largest model of acceptability knife head and the smallest model, cutting tool and realizable treatment. To intermediate area, in respect of aperture diameter, public errand, hole depth, quality and applied circumstance, it is a kind of crackajack solution. Above all, inside the tolerancepublic errand range that can change head broach to need to assure aperture to ask in place, exterior quality is Ra2.

In 5 μ M, specific requirement wants to use an occasion according to what differ and be decided. Some application circumstance may ask bigger hole depth, shorter accessibility and medium length, in addition, need taller stability and better cutting chance to extricateoneself from an awkward position and the capability that pour wine cup likely still. More important is the penetrable rate with knife head higher need, longer with more consistent service life. From the point of efficiency respect, knife head need can be more relaxed on the machine tool undertake conveniently changing. Graph 2 get in what can change head bit what there is security between body and knife head is brand-new interface. This enhanced the simple sex when knife head changes and security, make accurately fixed position obtains knife head to be propped up very well can change head broach to be able to change head broach to already applied old, according to the differred to already obtained different level success of broach structure. Can change head broach to also be put in a few potential weaknesses, to score greater success, new generation can change head broach to must overcome these weaknesses, among them the mainest is to ask interface has higher intensity and stability, can undertake smoother cutting and use taller cutting parameter. When broach application and the more maneuverable, efficiency that discharge bits is taller when undertaking knife head changes, the treatment dependability of the consistency of aperture quality and broach already was become must the point of first consideration. Why to already have in the market other and good bit and when can changing head broach to still be put in a few potential weaknesses, do we still need to you can change head bit? Because new generation can change head broach to have the following advantage,this is: Through fewer handling time, faster yield, longer cutting tool life and better machine tool utilization rate, can obtain lower weak opening cost; Through shrinking snickersnee head changes time can achieve taller manufacturing efficiency, change through improving knife head the treatment security with methodological better getatable, new interface design is crucial factor; The treatment dependability of broach is produced to rising is very main potential factor for efficiency, the influence that is asked by card of all sorts of different aperture character, outfit and material; Security is decided by the structure of cutting tool greatly, the generation that cutting tool writtens guarantee compose can bring about reject likely, needless machine tool machine down time and cutting tool damaged; Need not grind again, the meeting when be being ground again involves the issue such as card of grinding, coating, outfit, management and inventory, although knife head is one-time,use, but still reduced cutting tool cost; The sort that can change head bit is extensive, because this can pass appropriative or global solution, offer mix patulously the method that has specific aim more, with satisfy or optimizing aperture auger cut; Can prepare for follow-up working procedure, make final process OK be satisfied better or improve quality. The treatment economy of the intermediate range that the new generation that new generation can change head broach to be rolled out now can change head broach to be able to raise Kong Jia to be versed in greatly. This are new-style broach can be mixed as broach of contemporary whole hard alloy but of broach of dislocation razor blade admirable replace an option. New generation broach is mixed in ability of quality of penetrable rate, surface, dependability cutting tool outfit blocked a respect to make a lot of improvement, still include to use material of head of knife of hard alloy of coating of new tall tenacity, microcrystalline bead, PVD to pledge. A when new generation can change head bit significant advantage depends on it can be being ordered not only make, and already undertook optimizing for all sorts of application circumstances. This can use new safe technology, get the high accuracy interface between body and knife head, distinctive platoon the development of blade of bits chamfer structure, cutting and applicable wider diametical range and all sorts of step, length and receive a handle to wait. New generation can change head broach to be able to apply to wide applied range. The rotate speed when the machine tool is inferior, but when broach of dislocation razor blade cannot produce effect adequately, use can change head broach to be able to serve as a kind of solution. In the meantime, it also can dig the good solution of latent capacity of high-power machine tool adequately as. The development standard of broach should ensure namely can move smoothly at the beginning, have smooth cutting effect. To knife head, need to be able to be relaxed in any applied circumstances on the machine tool undertake changing. Now, new can change head broach to must have versatility, can drill simple hole not just, still should have the caboodle getting, bore a hole that get follow in a continuous line, undertake sunken / convex auger enter and get, and enter contain tilt exterior workpiece. Anyhow, broach must can apply bigger cutting parameter, make its apply to very wide application range. CNC Milling
