High-pressured refrigeration processes the application of cutting tool

High-pressured refrigeration machines means (HPC) , in current metallic treatment, acting more and more important role. Yi Sika is the earliest should market demand, the design creates one of companies of high-pressured refrigeration cutting tool. Developing the intent with high-pressured refrigeration original cutting tool is to answer the treatment of difficult treatment material, for example: The treatment of titanium alloy, chromic ferronickel alloy and other heat-resisting alloy. In practice, people discovery, when high-pressured refrigeration cutting tool is processing stainless steel and alloy steel, cutting tool life, productivity, and very big to cutting the control of bits to get improvement. Since 2000, yi Sika is all sorts of application of different user, the design made elevation of hundreds kinds of blame press cooling cutting tool, accumulated rich experience. Development of more than 10 years, yi Sika was developed already a series of cutting tool of refrigeration of standard high pressure, covered ISO lathe tool in the round, grooving knife, cut off knife set; Machine titanium alloy, high temperature alloy, cutting speed can promote 200% ; In the application that processes difficult treatment data, the control that cut bits is much better; Machine titanium alloy, heat-resisting alloy, alloy steel, cutting tool life rises 100% . And the development of cutting tool of series of refrigeration of JHP high pressure, cooling to high pressure cutting tool reachs the application in industry of medical apparatus and instruments in aviation industry, meaning especially far-reaching. The working principle of high-pressured refrigeration cutting tool: From outside the cooling fluid that pump of put maximum pressure comes out, the via of cool spray head with narrower and narrower by, its pressure is able to increase. The cooling fluid rate that comes out from nozzle is very high, direct eject arrives the cutting area between face of the knife before cutting bits and razor blade, dropped cutting temperature, protective cutting blade is absolved get thermal shock. When machining high temperature alloy, can produce very tall heat in metal cutting, after using high-pressured refrigeration to machine means, besides the heat in metal cutting that reduces cutting extent effectively, still make the brittleness that cut bits increases, break off easily. And get smallish cut bits, make cut bits to be twined no longer it is all round workpiece, treatment process need not worry bit because of what artificial purify grows again and stop often machine. Convention is cooling, cut area of the knife before bits meets those who prevent cooling fluid to reach cutting area; High pressure is cooling, cooling fluid can face of the knife before collimation of essence of life amounts to bit and cut the cutting area between bits, this prolonged cutting tool life effectively, make treatment process more responsible. And client of metallic treatment domain to shortening cutting machines cycle, raise treatment process dependability and the pursuit that acquire life of taller cutting tool, those who promoted application of high-pressured refrigeration cutting tool is increasingly extensive. Cutting tool of series of refrigeration of high pressure of Yi Sika JHP, have both not only afore-mentioned advantages, and cooling fluid spout and distance of bit cutting blade are closer, this brings the following and a lot of profit: -- treatment cycle is shorter: When machining titanium alloy and heat-resisting alloy, cutting speed can promote 200% . -- cutting tool life is longer: No matter be treatment titanium alloy, heat-resisting alloy, still be stainless steel, alloy steel, cutting tool life all can promote 100% . -- the control cutting bits with much better implementation: Even if processes the material that extends sexual beautiful or difficult treatment data, can obtain easily as before cut bits shortly. -- the effective refrigeration to cutting blade: Reduced the sensitivity with cutting fluctuant to heat blade. The treatment process of on the safe side. (1) limits of cooling fluid pressure: Low pressure is cooling (LPC) 30bar of ≤ of cooling fluid pressure. Have proper promotion to cutting tool life, do not have too big improvement to cutting the control of bits; Middling pressure is cooling (MPC) cooling fluid pressure 30 ～ 70bar. Can promote the control to cutting bits, drop the temperature of cutting area. Machine tool manufacturer can satisfy the client special requirement to cooling pressure basically. High pressure is cooling (HPC) cooling fluid pressure 70 ～ 120bar, it is the limits of cooling fluid pressure with JHP series the most commonly used cutting tool. Cutting tool life, cutting speed all gets rising, the control to cutting bits is much better also at the same time. Extrahigh voltage is cooling (UHPC) cooling fluid pressure 120 ～ 400bar. Because cooling fluid pressure is exorbitant, need to undertake unique design to cutting tool. When life photograph compares cutting tool to cool at high pressure, have small promotion. When machining titanium alloy and heat-resisting alloy, when the user in order to go after smallish cut bits, when taller productivity is a target, can recommend use extrahigh voltage to cool (UHPC) treatment means. (2) cooling fluid pressure and cooling current measure every JHP maximum pressure cooling arbor, devise the cooling fluid flow with have constant. Through adjusting cooling fluid is pressed force, controallable cooling fluid discharge. In Yi Sika example, explain with clear cooling fluid discharge to every arbor. The user needs to make clear pump of the buy outside its whether the cooling fluid flow that provides cutting tool place to need, and cooling fluid discharge decided what whether can realize an user to expect treatment result. Outside on buy pump, can indicate normally the greatest cooling pressure and the largest flow. (3) cut bits and cooling fluid pressure through adjusting cooling fluid pressure comes specific value, controallable cooling fluid discharge, final implementation breaks bits. Specific value reachs by treatment material change because of cutting tool. In applying actually, if observe, cut bits to fail to break off, can come true to be opposite finally through increasing cooling fluid pressure appropriately the control that cuts bits. And the specific value that exceeds cooling fluid pressure, as the promotion of cooling fluid pressure, obtain cut bits will smaller and smaller. Also be namely, through amending cooling fluid pressure, can realize the control of pair of appearance that cut bits and size. Cutting tool of series of Yi Sika JHP, already covered ISO lathe tool in the round now, turning / grooving knife, cut off a knife. Cent narrates at falling: -- ISO lathe tool: To ISO lathe tool, yisikadi lays 4 kinds of cool spray head, apply at the ISO car razor blade of different figure. Yi Sika still undertook improvement to ISO lathe tool, besides the high pressure that withholds convention cooling cutting tool is located in bit upper part on carry cooling fluid spout, still pay lower part in the knife, added spout of front cooling fluid. Cooling fluid spout is carried on, make cutting fluid can nonstop area of area of the knife before bit; Spout of front cooling fluid, make cooling fluid can nonstop area of area of the knife after bit. Both union, the to cutting area refrigeration in enhancing treatment process is controlled. Be aimed at spout of front cooling fluid, yi Sika returns a design to one adjust bolt, adjust its in order to go to the lavatory to close. -- turning / grooving knife and cut off a knife: High-pressured refrigeration is being machined all sorts of be machined in the application of material, the control that cut bits all much better. Process difficult treatment data, for example, machine chromic ferronickel alloy and titanium alloy, use groovy and cooling means, it is very difficult that implementation breaks bits; And use high-pressured refrigeration means, can realize the control to cutting bits outstandingly. High-pressured refrigeration can decrease to eliminate appearance of the tumour that accumulate bits even; When should machining stainless steel and high temperature alloy especially, the effect is more apparent. Cooling cutting tool lists the standard maximum pressure that provides Yisika at present now as follows: (1) ISO lathe tool, arbor of in the right way and CAMFIX CAPTO receive knife handle of type of degree of lip-rounding; (2) turning / grooving knife and cut off a knife, have knife of CUT-GRIP Xiang Yu the Conqueror, knife of PENTA5 horn Xiang Yu the Conqueror, TANG-GRIP stands outfit wait from knife of the chamfer that place type. When using cutting tool of series of refrigeration of JHP high pressure to undertake ISO turning and grooving are machined, need to notice, cooling fluid pressure does not exceed cutting tool but susceptive is the biggest pressure of safe cooling fluid. Series of ISO lathe tool, pressure of the biggest safe cooling fluid is 300bar; Turning / grooving series, pressure of the biggest safe cooling fluid is 340bar; Cut off series, pressure of the biggest safe cooling fluid is 300bar. Use cutting tool of refrigeration of standard high pressure, introduce forward position technology, improvement machines operating mode, effective promotion machines the ability of difficult treatment material.
