The requirement of 1 pair of cutting tool
Numerical control lathe can hold turning of thick, essence concurrently. For coarsen car can big penetration of a cutting tool, big take a knife, intensity of cutting tool of requirement thick car tall, durability is good; Fine vehicle is to assure to machine precision above all, the precision of requirement cutting tool is so tall, durability is good. To decrease the time that change a knife is mixed convenient to the knife, answer to use machine clip knife more as far as possible. Use machine places a knife to be able to feel automatic plan a requirement to the knife. If say to go up to traditional lathe,using machine clip knife is a kind of proposal only, so machine clip knife is being used on numerical control lathe is a kind of requirement. The cutter hub of machine clip cutting tool, ask production precision is taller, the means of clamp razor blade should choose more reasonably. As a result of machine clip when lathe of knife mount numerical control, do not add spacer to adjust commonly, the precision with so tall point of a knife should get assuring when make. To growing the internal diameter arbor with diameter larger proportion, had better have fight brace up structure. The cooling fluid of internal diameter knife had better introduce cutter hub first, again from knife head around ejective. To bit, bit of coating hard alloy should be used below most circumstance. Coating is in taller cutting speed (> the advantage that body of the ability when 100m/min) reveals it. The cutting rate of common lathe is average go up not to go, the hard alloy bit that uses so need not coating. Bit coating increases cost to be less than one times, and double above can increase in the durability when be being used on numerical control lathe. Numerical control lathe used coating razor blade to be able to raise cutting rate, can improve treatment efficiency thereby. Coating material has carbonization titanium, nitrogen to change titanium and alumina to wait commonly, in the material that also can besmear a few differ on same razor blade, make compound coating. Numerical control lathe has higher demand to the chamfer breaking bits of bit. The reason is very simple: Rate of automation of numerical control lathe is high, cutting often undertakes in sealing closed circuit border, undertake very hard in turning process dealing with artificially to cutting bits in great quantities so. If cut bits to be broken badly, it can be twined go up in knife head, press bad bit possibly already, also can press cutting face. The hard alloy bit that common lathe uses is two dimension break bits chamfer commonly, and razor blade of numerical control turning often is used three-dimensional the chamfer that break bits. Three-dimensional the form of the chamfer that break bits is very much, be to finalize the design commonly inside bit manufactory standard. Its common characteristic is the function that break bits the good, range that break bits is wide. To the spare parts with particular simple material, after cutting parameter is placed, the chamfer that should notice to pick good bit. A few theory can be made discuss in choosing a course, but mainer is to undertake solid cut an experiment. In a few circumstances, OK also the chamfer according to already having bit will revise cutting parameter. Requirement razor blade has tall durability, this is need not of doubt.
Numerical control lathe still asks the consistency of bit durability is good, so that govern a function at using cutting tool life. When life of use cutting tool manages, the set principle of bit durability regards a basis as the razor blade of lowest of this durability in approving bit. Below this kind of circumstance, the consistency of bit durability is more important than its mean life even. As to precision, ask precision consistency is good between each razor blade likewise.
2 pairs of blade holder (clip) requirement
Knife (blade) provide very few and direct outfit to be on the tool carrier of numerical control lathe, blade holder is used commonly between them (also call a knife clip) make transfer. The structure of blade holder basically depends on the configuration of the exterior of the appearance of cutter hub, tool carrier and tool carrier to main shaft means these 3 elements. The sort of nowadays blade holder is various, the manufacturer goes each its thing, standardization rate is very low. The standardization rate of machine clip cutter hub is higher, sort and norms are not so too much; Tool carrier is gross to the configuration means of machine tool main shaft have a few kinds only; Only the exterior of tool carrier (basically be to point to the part with blade holder connection) type is too much. The user is when type selecting, answer to reduce phyletic, type as far as possible, with interest government.
