In aircraft spare parts and structural member, involve auger cut composite material and the application of the material that fold a layer to basically be many bolt aperture and rivet the treatment of aperture. By operator direct hand moves an operation to mean these working procedure to facing particular challenge. Use a hand to move pneumatic drill to undertake machining apt not steady working condition, craft stability assures very hard. The working experience of the property that uses equipment and cutting tool so and operator will affect aperture quality and manufacturing efficiency directly. If use ordinary hand to move cutting tool to undertake aperture machines the worry that suffers broach capture effect easily, still need very tall thrust to penetrate at the same time aperture, the quality that machines the aperture that come out so, efficiency and operator exhaustion degree will get negative effect. If do not solve this kind of problem, aperture exit may appear not acceptability burr, Kong Chuduan is statified and the blemish such as the fiber that cuts off hard. Common broach is when cutting composite material, cutting action difference and feed change are big, this asks operator balances the adverse effect that brings by common broach through proper operation, the outcome produces a waste product more possibly. In aviation industry, the commonnest composite material is carbon fiber increases plastic (CFRP) , its aperture quality is defined according to a few limits normally, often involve the following aspect: Surface roughness of dimension and ovality public errand, surface and burr are formed, form of linearity and central line verticality, bucket and horn mouth. Should fold when having aluminium alloy or titanium alloy, through cutting cutting tool effective platoon bits appears particularly important, because the metal cuts bits,can damage surface of answer material aperture. Its are challenged is the quality consistency that should gain satisfaction already, want to ensure the member that operate is safe again, but most important is to make cost want to have competition ability. The ply that carbon fiber enhances plastic material is relatively lesser, no matter woven or one-way belt often is shallow aperture treatment in the structure. Typical craft asks to include exterior surface roughness to be in Ra 4.

In 8 μ M, treatment aperture periphery is statified do not exceed 1mm, and crack-free. Expect to folding plank for, it is to the requirement of exterior surface roughness answer material layer is less than Ra 3 normally.

2 μ M, metallic layer Ra 1.

6 μ M. Limits of aperture public errand is in ± (0.

02~0.

04) Mm, and carbon fiber increases plastic (CFRP) the part does not allow a metal to cut trace of bits frit corrode. Be less than ± when bore diameter public errand 0.

When 025mm, normally need undertakes bore with a reamer is cut. When the extensive influence of cutting cutting tool should not use CNC machine tool or calm feed device, the property that operator needs to rely on their ability a dab hand to use a tool will make sure aperture quality is in limit range, finish be asked to get cut Kong Shu everyday. In these application, the application that the hand uses a tool depended on successfully the rate that efficiency of cutting cutting tool produces. Volume of power of cutting action, cutting and direction, likely cutting parameter and life of getatable cutting tool are the element that cutting cutting tool wants to think, they are having decision effect to aperture quality and the economy of production process. In the production economy respect of these working procedure, the factor that affects production competition ability has a lot of, include among them: Consistency of the time that bore place spends, quality, whether need 1 or 2 working procedure, auger cut cut with bore with a reamer and cutting tool cost and grind option again. The development with cutting the closest cutting tool Shanteweikekeleman and Precorp give full cooperation, development goes a series of new standard broach, reamer and Huo to get, the in an attempt to is the commonnest snail keyhole inside efficient treatment aviation industry and rivet aperture. Take the accumulates for a long time experience inside course of study, these cutting tool are developed for composite material solution only. Draw lessons from order make experience of cutting tool success, and the existing aperture treatment, treatment that decorate a border and the development that the surface machines range of products of standard cutting tool, facilitated jointly new CoroDrill 452 series. Any leftover fiber that the fiber that the cutting action of new broach decided how to keep clear of to already was cut off directly and Kong Zhong appear subsequently. Cut action to also can undertake optimizing occurrence in order to avoid broken. The thrust when broach getting penetrates hole decided statified the happening of blemish odds. New broach place arises get cut force to reduce, thereby will statified blemish falls the smallest. The broach that the immanent instability of Nextpage working procedure decided to the hand uses pneumatic drill needs taller tenacity. For this, hard alloy broach is optimal solution. To prolong cutting tool life, use at carbon fiber to strengthen plastic bit normally plating has coat, or complementary with agglomeration diamond (PCD) . But, pneumatic drill getting is moved to cut a field in the hand, the balance between tenacity and wearability is mixed unlike cutting tool life worry the concern between again. In mix relative to briefer cutting tool life what handle without coating is heavy after grinding, high strenth broach is incidental change. This is the one part of the production economics formula that uses in the light of this kind, among them clip of parameter of cutting tool cost, cutting, cutting tool is held and cutting tool life is variable. Move aperture to process application to the hand, the different value that applies to this domain considers the base that is series of cutting tool of new-style standard cutting with respect to its itself. Broach of standard of CoroDrill 452 of range of products increases for carbon fiber only plastic the hand that strengthens plastic metal to fold a Kong Jia to be versed in with carbon fiber uses pneumatic drill application and design. To product of CoroDrill 452-C series (use at CFRP) , it is the has a lot of advantage union system that has proved. The design that wins patent is combined -- chamfer of left helix coming back and right hand-type broach promoted smooth cutting action, and the smallest change or removed capture effect completely. Long and sharp cutting blade poured awl to be offerred for the cutting with all clean and orderly fiber opposite bigger cut corner. The distinctive chamfer that discharge bits can offer admirable aperture circularity not only with the structure that get a tip, will get at the same time cut axial force the smallest change. Very low feed power needs only when cutting, to the Kong Chuduan of answer material injury is accomplished the smallest. Fold layer CoroDrill 452-CM to the metal, except the advantage of low cutting force, still can think whether choice broach is compositive get a share beforehand. This action is to reduce the difference that different place produces the fabricating characteristics between material, offer taller aperture precision and surface roughness. Fold in different material the difference of its hole size is dinky between the layer, eliminated aperture to export burr. The metal is folded board broach has Shuang Ren to take a design to be able to ensure the stability that machines a process, from this the function of cutting tool and product quality have farther promotion. From centering the design that get a tip makes get whittle answer material metal folds plank makings is more smooth, ensure aperture precision very easily. Bore with a reamer is cut and reamer cuts precision work the likelihood when a few aperture needs to undertake 2 times taking a knife with reamer. When the requirement extremely close together public errand is mixed when fast face quality, coroDrill 452.

R reamer (C or CM, use at carbon fiber to increase respectively plastic or fold plank to expect) application is oriented set can win noncombatant duty 0.

The aperture in 02mm. The reamer of blame coating hard alloy of these tall tenacity has guide pillar of an a flight of stairs (guide pillar dimension and CoroDrill452 series broach get cut oriented aperture photograph to match) , can reduce axial cutting force effectively, in order to ensure fast face surface roughness, end goes out in burr of exit of metallic layer aperture and aperture of answer material layer statified the smallest change. Use hand moves cutting tool to undertake Huo Kong Shi, huo getting does not need to bear again long broach and stress of susceptive of the place when reamer works and flexural strength. This is meant can surely compositive more fragile PCD enhances plastic cutting blade as treatment carbon fiber, bring very long cutting tool life and the possibility that can grind again from this. Wear well of hard alloy guide pillar, cooperate Huo nest spacing again implement the precision that can ensure 100 ° pour wine cup with 130 ° and correct deepness. the operator that the last word uses cutting tool to using a hand, build composite material aperture to machine series of standard cutting cutting tool to need proper eclectic. The challenge of aerospace domain and demand mix surely namely most the cutting tool material of wear-resisting. Contrary, the intensity of hard alloy is used at offerring security and advantageous cutting tool cost. Want to optimize this domain, the development of form of cutting tool chamfer is mixed in function of the quality level that achieves satisfaction, cutting tool production reachs crucial action since efficiency respect.
