The high speed milling of hard steel of temper by dipping in water is machined

4 control software is wrapped. In addition, of structure of modern bus line and connection speed rise make controller can more effective, more reliable the ground and main shaft communication. All sorts of function components (be like servo electric machinery and shafting) must the requirement that can contented high speed machines. The design of servo electric machinery must can offer the biggest torque and won't make electric machinery overload, in order to raise the acceleration of each movement rod, maintain smooth stability of motion at the same time, in order to protect mechanical component. A lot of new-style number servo can be offerred 1, 6 million pulse / ball guide screw the resolution that every turn, conduce to implementation thereby this one task. Current, shafting of treatment of function first-rate high speed is the mixture that uses steeliness raceway and ball of pottery and porcelain shafting, this kind of shafting has smaller torque below higher rotate speed, it is better to be had bright and clean spend and insulating property. In addition, the processing system that cut bits also nots allow to ignore. In high speed treatment, because metallic purify rate rises greatly, accordingly, cut bits effectively from treatment area eduction crucial. When hardness of high speed milling is more than the workpiece material of HRC45, produce vibration and high temperature very easily, may bring about machining error, flutter, cutting tool thereby invalidation and a few otherer problem. To answer vibration and high temperature, the measure that needs to adopt above all is the machine tool with introduce stability good and cutting tool collet. Generally speaking, use the cast that has better tigidity and greater weight, can increase the stability of the machine tool. It is particularly important to cast-iron component is out of shape to reducing bending and provide thermal stability. The structure of the machine tool jumps over massiness to bear fruit, be helpful for the cutting force that when antagonism processes oil hard data, brings to bear on more. Although this does not mean you to should buy a machine tool merely according to weight, but if you need to undertake hard milling is machined, criterion the weight of the machine tool is a consideration element that nots allow to ignore. The temperature that another when need a consideration main character is a machine tool controls capacity. When the time that when treatment a spare parts continues is very long, the machine tool can produce the heat that causes by surroundings temperature change to be out of shape. The machine tool with good stability does not allow this kind of temperature to change to cause negative effect to the cutting treatment of the spare parts. A lot of moulds (especially large mould) often need treatment of the ability between a few climate to finish, what be not abrade surface to maintain is bright and clean spend and transfer between knife mark glossily, become very important to the control of temperature. The repeatability that the main shaft of good refrigeration offers, heat that can forecast expands conduce to retain these character. Refrigeration of main shaft center is a patent technology that Makino company develops, it can reduce the heat of high speed main shaft effectively to expand. The heat that central refrigeration can restrict main shaft expands quantity, make main shaft is stabilized quickly. Enter the cooling oil pump that controls temperature accurately main shaft center, can lubricate already main shaft, can undertake cooling to it again. As to cutting tool collet, you need to decide which kinds of collet suits his treatment most. For example, mill collet is had decrease outstandingly brace up function, good way jumps precision and tigidity, suit the rough machining of hard steel of temper by dipping in water very much. But, the precision of mill collet is not quite tall, accordingly, pinchcock head may be a kind of better choice. The biggest question that the consideration needs when choosing cutting tool collet is right its are decreased brace up function asks to have many tall. System of cutting tool collet should not allow energy to pass into main shaft interface (the main contact between cutting tool and main shaft is nodded) . Use cutting tool collet to decrease brace up the system draws energy, the harm that can cause rough machining is decreased to the smallest, prolong cutting tool life thereby, raise a shafting life and reduce diameter to jump error. Normally, the diameter of rough machining cutting tool jumps the error is about 0.

127 - 0.

003mm, and the way that clip runs the finish machining cutting tool in shrinkage fitting collet jumps the error can be achieved about 0.

05 - 0.

001mm. Make excellent bedspring collet suck brace up the gender is good, diameter jumps the error is small, can pack the cutting tool that places a variety of dimension, apply to treatment of most essence mill. If the precision demand to cutting tool collet is higher, criterion shrinkage fitting collet may be a kind of optimal choice. Nevertheless, in major rough machining, shrinkage fitting collet cannot absorb the vibration that high speed produces when hard data of thick mill oil. Generally speaking, shrinkage fitting collet should be used at semifinishing machining and finish machining. Why to no matter use,plant cutting tool collet, when hard steel of temper by dipping in water of high speed milling, the balance of collet can become particularly important. When cutting system is in the biggest rotate speed, all cutting tool collet should be achieved 2.

The balance of 5g asks. When high speed processes hard steel of temper by dipping in water, need uses the cutting cutting tool that designs technically. Do not want a tentative idea to use groovy cutting tool also can put up with is dealt with. The cutting tool that manufacturer of a few tool provides is OK cutting hardness achieves HRC50 (even HRC60) workpiece material. All element that process a system to ensure (collet of machine tool and cutting tool, cutting tool) can satisfy treatment requirement, must undertake to the system cutting experiments. Ensure uses process designing software allows to use all sorts of likelihoods to provide the cutting technology of value extremely to hard steel of temper by dipping in water of high speed milling. Cycloid thick mill, effective guide and derive control, arc paragraph plan to combine course of knife of corner, big common difference, cut the technology such as the examination to be opposite possibly too hard milling ability produces an effect. If CNC program does not allow to control these element or use these technologies, should change new software. Normally, the software that can use these technologies machines special design for hard milling. Another main process designing point is to want understanding how to choose cutting width and cutting deepness according to the hardness of workpiece material. The effect that this issue that often is ignored easily may make hard milling is machined is widely divergent. The watch shows the basic guideline that is Makino company 1 times. This company suggests, the bear that cut bits should maintain in cutting tool diameter 1% the left and right sides. When hard steel of temper by dipping in water of high speed milling, recommend diameter of cutting tool of put apart semifinishing machining 5% as surplus (the material purify that stays after rough machining is measured) . When expressing hard steel of temper by dipping in water of milling of 1 high speed cut wide with cut deep work hardness - under HRC45 - HRC45 ～ 58 - HRC60 above radial is cut wide - of cutting tool diameter 50% - of cutting tool diameter 45% - the 45% axial of cutting tool diameter are cut deep - of cutting tool diameter 10% - cutting tool, need decides the effective diameter of cutting tool, with the computational formula with proper basis, use rate of the biggest feed to undertake machining, shorten treatment cycle time. Must ensure your machine program and process designing ability can satisfy the requirement of hard steel of temper by dipping in water of high speed milling. If you did not use appropriate treatment means, may damage cutting tool, make workpiece discards as useless. If high speed never is before you cutting and (or) work out of treatment of hard steel of temper by dipping in water passes machine program, falling through the circumstance that grooms certainly, you may finish this one job very hard. Soft milling of hard milling of high speed hard milling and low speed and high speed is disparate. Same treatment rule is not certain again applicable, permission error range is greatly narrow also. In view of these facts, the workshop that uses high speed hard milling must undertake to its employee necessary technology grooms, in order to get used to this kind of change of treatment task. For example, the different point between hard milling of high speed soft milling and high speed is, people apt thinks, can accept blemish of a few treatment wait for the working procedure from the back to undertake treatment, nap or light are rectified again. If your purpose is,machine cycle time through omiting working procedure of thick mill mild steel will shorten, so, after hard to temper by dipping in water work undertakes milling, undertake benchwork nap impossibly to its again. In treatment of high speed hard milling, each measure must excelsior, must enter next step to the ability after workpiece has tightened inspection. Must be opposite each measure (get work from the check of semifinished product eventually check) make this plant " free of error " procedure. If one is put in the workpiece of blemish to was not given by check, or flowed into below one working procedure, whole technological process is met " break down " , bring about treatment cycle time to lengthen thereby, and you are forced possibly also to restore the tradition previously to machine means. When using new machine tool and cutting tool system to undertake high speed hard milling, the circumstance that if produce machine tool, main shaft and system of special cutting tool,damages, will create high pecuniary loss and wasteful and many time. Accordingly, must undertake to personnel of technology division and machine tool operation the technology grooms, ensure they have the capacity that uses high speed hard milling correctly to process equipment and tool system. Groom not only important to protection equipment and it is very important to reduce percent defective, and the metabolic precautions averts perils that can help the other employee of the enterprise shed likelihood happening to workpiece. The business that a lot of executive high speed process realizes, a few link can form bottleneck very quickly. When the rhythm that is used to deciding with some kind when people has an operation, if among them a specific part is quickened suddenly, cause a disorder very easily. When you begin to carry out high speed hard milling, this become particularly important, because machine cycle time,can shorten considerably than in the past (can shorten normally 50% above) .
