Well-known, lathe of nicety of Ha Ting QUEST CNC and exceed nicety (Super Precision) lathe, already was the lathe product of industry tip, the configuration on accurate lathe exceeds in Hating static press slideway more can the function of the freeboard precision of aggrandizement machine and further hard cutting. The trend of machine tool development of prospective whole world will be high speed change, exceed nicety, accept rice is changed and informatization, at the same time the concept of zoology environmental protection also can spread to be designed in new generation machine tool gradually. Ha Ting company is in exceed precision innovation technology to go up, of will new research and development static press slideway technology configuration to be in lathe of its QUEST CNC. Static pressing slideway is one of Ha Ting company's numerous technology patent, its fundamental resembles train of magnetism in suspension. Static pressing slideway is to use hydraulic pressure to support slide block shift, magnetism float is to use magnetic field force to let train in suspension. Static the layer of high-pressured oily film that presses the slide block of slideway to be gotten on by slideway is propped up, touching the smoothly sudden shift below touched state with slideway, won't produce any wear and tear. Static the hard path that the function that controls slideway shows to surmount a tradition far or ball (roller) , these traditional mobile parts are the osculatory generation friction that relies on metal and metal, also bring about wear away. What place of QUEST CNC lathe configures is static pressed slideway to provide following and advantageous function: The suction that · exceeds actor brace up the effect. · enhances hard cutting (HardTurning) function. · bumps by accident to the machine of machine defend. · increases cutting tool longevity. · prolongs machine life. · promotes each axis floating rate. Circularity of · further cutting. · improves cutting surface surface roughness. Static press oil of hydraulic pressure of slideway job principle by external system of hydraulic pressure power is transmitted to slide block of every hydraulic pressure inside, every slide block configures 6 oil bear, prop up slide block by right of high-pressured oil even ground in suspension go up at slippery course. When cutting force increases, oily bear the oil pressure force inside also becomes direct proportion increase, came true to compensate a function automatically, make cutting force and oil pressure prop up force to achieve corresponding balance. The hydraulic pressure oil after the loop is carried by slide block with often pressing condition circumfluence to gasoline tank, can repeat use. Hydraulic pressure compensates a function automatically to be in usually, the oil inside slide block bear oil pressure holds the position in stability, the clearance of slide block and slippery course also maintains certain span. Increase when cutting force, oily to what prop up bear the pressure with larger generation, slide block and slippery course clearance because of cutting force narrow, oily bear the oil pressure inside can become pressure boost of direct proportion ground. The automatic compensation pressure boost that this phenomenon place produces can avoid slide block, the clearance of slippery course disappears, prevent the contact between slide block and slippery course to wear away then. Automatic compensation function also offerred oil pressure to with a ha hold out hard cutting (Hard Turning) vibration isolation function and bump into the protection of machine. Static the contribution that presses slideway to go up in Ha Ting machine tool with a ha holds out accurate lathe the lathe compared with course of other and traditional line, can behave the promotion of its remarkable accurate turning ability and multinomial function more, if cutting tool loss is reduced, machine life is lengthened, the axis moves to rate increases and bump into the protection of machine. From below list, the result of exterior surface roughness of comparable various lathe. Static press what the main good point of slideway actors or actress especially to avoid brace up effect vibration is the main reason that causes cutting tool to damage prematurely. If the machine tool has relatively of beautiful decrease brace up (suck brace up) structural design, with respect to the exterior surface roughness that can improve cutting tool life and work apparently. With a ha hold out a machine tool to be on the design, the mixture data that used tall damp coefficient (Harcrete) lathe bed, add static the function that controls slideway. The character of cement lathe bed is the suction that exceeds actor brace up the effect and absolutely low hot deflection. Undertake is not successive cutting on Ha Ting machine tool, can depend on static lathe bed achieves the Harcrete of the hydraulic pressure that controls slideway and tall damp coefficient to be decreased significantly brace up the effect. Increase an axis QUEST 8/51 of floating rate Ha Ting and 10/65 lathe configuration are static the ball silk lever that controls slideway and double lead, can make Z axis rate rises by 38m/min to 58m/min, higher floating rate can shorten cutting cycle time. Further work true circularity deserves to have in product of Ha Ting machine tool static press slideway exceed accurate lathe, its cutting true circularity can be achieved 0. 00012mm, without configuration static the Hating that presses slideway exceeds accurate lathe, its cutting true circularity can be amounted to 0.
00038 ～ 0.
00050mm. Advantageous exterior surface roughness with a ha holds out exceed accurate lathe, its turning surface surface roughness is made an appointment with 0.
00020mm (Ra) , configuration is static those who press slideway exceed accurate lathe, surface roughness of its turning surface can be achieved 0.
00010mm (Ra) . Defend the test that strikes the effect to be passed for many times, show fall in extremely tall wallop, static press slideway to do not have any injury. Because hydraulic pressure force compensates a function automatically to be able to prevent the contact of slide block and slippery course to collide,this is, at the same time bring down bump into the attaint of machine accidentally. Lengthening cutting tool life and the cutting that exterior surface roughness with a ha holds out to check significantly is to use the workpiece after sclerosis to undertake is not successional cutting, as a result life of indication cutting tool is lengthened amount to 36% , the cutting tool of full year can save about 29000 dollars, at the same time workpiece surface surface roughness is improved 43% , from 0.
The surface roughness promotion of 00013mm (Ra) comes 0.
000076mm (Ra) . The function of further hard cutting (Hard Turning) comes for years, ha Ting already was the hard cutting expert with established industry. Hard cutting can undertake cutting in the light of the workpiece of hardness 45 ~65 Rc. Static pressed slideway to promote Ha Ting hard cutting technology to higher administrative levels. The oscillatory meeting that hard cutting produces in be not successional cutting especially is reduced by big earth, because static press slideway to have taller static tigidity and dynamic tigidity. Static tigidity is to point to fall in rated load, the deflection between slide block and slideway. The dynamic tigidity that in cutting the place in undertaking produces is to show the natural frequency in machine structure itself falls, measures oscillatory amplitude volume. Because static press slideway to have admirable vibration isolation effect, conduce to a machine producing admirable dynamic tigidity. Hard turning (Hard Turning) but local the CNC lathe that replaces grinding Ha Ting is added static press slideway, can offer low brace up hard cutting effect, make make much work reach the mass like grinding. This makes hard cutting is made in seed profit in act more important role. The proof in the test, ha Ting's CNC is static press slideway lathe, can undertake is not successional hard cutting to gear and keyway, and the precision that achieves gear place easily to need and exterior surface roughness. The benefit of hard cutting and grinding compare an advantage to be as follows: Reduce significantly beforehand device man-hour, restrict the benefit making Cheng of Cheng and faster treatment cycle hard cutting fewerly: Control the amount that cut bits more easily, more purify that cut bits are measured, can undertake at the same time inside round hole, outside round cutting. Have whorl cutting function, lathe deserves to go up in mark, the treatment of workpiece of achievable complex external form. Ha Ting makes a test with standard workpiece, will compare hard cutting and grinding beforehand device man-hour and treatment cycle time. The test hints workpiece and cutting tool time save 340 ％ as a result, treatment cycle time is economic amount to 575 ％ . Bouncier run-of-mill cutting and hard cutting can be together on a lathe make Cheng Jin go. Compare the efficiency of hard turning and grinding, you can achieve easily 4: 1 with 6: Purify of 1 tall cutting is measured. If workpiece happening designs alteration, change on lathe it is easy to make Cheng make Cheng than be being changed on grinder a lot of. Grinding is the treatment of a high cost, the treatment because of it periodic and treatment preparation time is very time-consuming. The QUEST lathe price that lowers machine fixed assets to invest Ha Ting is far under " coequal class " grinder. Although advanced grinding machine can undertake multinomial grind cut a function, but the price however outclass lathe. Additional, of grinder additional deploy, if balancer is mixed,repair emery wheel implement, also raised the cost of grinder. If abrade workpiece can be finished by cutting, lathe of use Ha Ting will process work, can create more profit. Reducing cutting tool of hard cutting of cutting tool inventory is cheaper than emery wheel a lot of, and do not occupy a space. Hard cutting uses CBN razor blade to undertake cutting, can very easily control cutting and quantity of fast the purify that cut bits. Place of hard turning of zoology environmental protection arises cut bits to compare grinding powder more accord with environmental protection condition. Hard turning does not need to use cooling water sometimes, the cooling water that can reduce pollution to pass reclaims, can reduce cost at the same time. CNC Milling
