Overcome the difficulty that oil hard data machines

005 μ M is not difficult. Current, tool supplier already was developed can bear this kind of cutting tool that machines a condition, machine tool maker already also produced a CNC lathe that can satisfy place of these new-style cutting tool to need stiffness. Accordingly, horniness material turning is OK from the following Zhu Fang the face accelerates production: Spare time undertakes to oil hard data turning compares grinding to need man-hour to want to final measure place little, because the metal of turning excises grinding of fast classics prep above,this is, and, the treatment of much talk working procedure can have in holding clip. Handlers needs to assemble and unassemble only, can complete full treatment, came true thereby seasonable (Just In Time) production. Reduce cost spare time is managing money. Besides, use lathe will replace grinding machine, the investment cost that means a machine tool has bigger fall. The turning of better oil hard data is in quality assure dimension precision and respect of exterior surface roughness, be close friends more than grinding. You can expect most horniness material to the total public errand when turning takes control to be in 0.

005mm less than, control of exterior surface roughness is in Ra0.

Less than of 4 μ M. Of course, so accurate surface surface roughness needs special measure, but should obtain Ra0.

4 μ M~0.

8 μ M is easy to do. Working procedure quenchs hard data turning can discharge the grinding working procedure of a lot of forms lesser, and polishing and working procedure of other precision work. Be opposite especially complex model the treatment of the face, turning can walk along orbit continuously, save next treatment cost not only, more significant is, can a lot of outside assist the work of treatment takes him to do. The reject of turning of hard data of wasteful and lesser oil is few. Because of use cooling fluid and normal turning identical, need not choose cooling fluid additionally and create needless waste. Have more very person, can choose next undertaking doing turning to imposing cooling fluid condition. Make you avoided the waste of cooling fluid and reject workpiece. Turning of oil hard data still can be absolved take a lot of work the waste residue of costly reclaims with processing problem. To make temper by dipping in water hard to the requirement 　 of power and stiffness material turning can achieve the biggest result, the correct union of machine tool and cutting tool is very important. For example, we are in in thick car operation, should use knife of pottery and porcelain, use 0.

The feed of 28mm/r, with 1.

When the penetration of a cutting tool of 9mm is measured, make with respect to need 15kW electric machinery outputs the load of 65% . This lathe will quench steel of 50mm of hardness 62HRC, diameter car of one aspect of the matter is controlled to 25mm, return turning to give radius of cone, circular arc and other and complex appearance at the same time. Although need to have high power to undertake engorge knife measures cutting, but discovery of a lot of users, be not below most circumstance such. Because most temper by dipping in water is hard,the treatment of material is finish machining. General and OK on bed of preexistence general be open to traffic thick car, put apart 0.

25mm~0.

The surplus of 38mm, complete precision work at technology of turning of material of horniness of the recycle after heat treatment next. The another requirement of turning of hard to temper by dipping in water data is stiffness: Include machine tool, cutting tool and work. If any link in machine tool installation lack stiffness, can cause quiver. To can win the precision that can compare with grinding photograph and dimension noncombatant duty, the machine tool must have particularly tall stiffness since lathe bed. Traditional cast-iron lathe bed and granite polymer are compared, do not suit to undertake hard data turning. Of polymer lathe bed fight oscillatory ability to compare cast-iron 20 times taller, make the vibration on main shaft is installed only in the main shaft on cast-iron lathe bed 1/3 the following. Reduce as far as possible dangerous extending a capacity is the another weapon that reduces vibration. From theoretic tell, workpiece clip holds device to should make what place the bearing before workpiece stands by main shaft as far as possible, cutting tool should stand by knife tower noumenon as far as possible, and do not appear cantilever condition. For this, main shaft internal energy installs the lathe that places pinchcock head directly quite. Collet the bearing before making workpiece is far from main shaft, not only clip holds power small, can increase oscillatory chance especially. 　 of new breed cutting tool changes boron with knife of pottery and porcelain and cubic nitrogen (CBN) hard data of temper by dipping in water of cutting tool treatment is very good. These cutting tool got flying development in short time, some tool manufacturer claims: Want a machine tool to use only correct, their cutting tool can shorten than grinding time 300% , can raise cutting precision. The cutting tool of pottery and porcelain that these suppliers recommend has the horn before losing and bigger T- to pour arris, should pour arris to be in only cutting tool - workpiece increases pressure on mind extent. As contrary as this, CBN the particular case according to workpiece, it is OK also to can have adverse without this kind T- pours arris. For example, when undertaking interrupted cutting with CBN, with respect to need bigger T- pours arris to bear oscillatory. The use meeting of cutting tool of pottery and porcelain is more and more general than CBN, this cost as a result of it is inferior, also the reason with the cutting more blade because of them. However, they are extremely easy be heated bilges crack, in addition, if edge is repaired,grind undeserved when, unfavorable undertake interrupted cutting. Although CBN is more expensive than pottery and porcelain much, but its cutting performance is good much, treatment is bright and clean degree tall, service life is some longer also. In some undertake choosing between material of two kinds of cutting tool, be how to make appearance of qualitative, geometry and cutting speed mix workpiece material feed and the job that its get used to. Some users normally not constrained at be being compared one by one, the cost that makes to same work place with all sorts of cutting tool however, and can arise how old benefit is choice principle. These users use the rubiginous skin that the heat treatment of thick car of knife of pottery and porcelain with inferior value often remains and iron scale to wait, next, have precision work with betterer CBN cutting tool. Generally speaking, if sclerotic deepness is more than desire the material deepness that the car goes, had better choose CBN. Choose correct exercise method 　 to consider from economic position, turning of oil hard data is with the process closely related workpiece character. It suits cutting to have complex circular arc, point of view particularly, and the workpiece with the geometrical very complex form such as radius. You can use the method of turning of process designing of odd point of a knife, fast economic ground completes work, and need not buy figuration emery wheel for grinder. According to experience, turning of most horniness material is the cutting speed with 91-150m/min is mixed 0.

05-0.

The feed speed of 13mm/r undertakes. Essence of life cuts deepness of penetration of a cutting tool to be commonly 0.

08-0.

5mm. Accordingly, how to control the purity with nice simple capable person, and the heat treatment before turning, thick car and figuration working procedure, the payoff that makes the precision bulk that this exercise can achieve. If workpiece hardness is fluctuant,only 3 Rockwell hardness are worth (citing says) , the cutting pressure of cutting tool makes to enough with respect to meeting change your guarantee against 0.

The dimension precision of 005mm. Not stable hardness and deepness of inhomogenous penetration of a cutting tool, metropolis attaint is machined this kind. Accordingly, should use eligible data, retain constant cutting power, make sure heat treatment hardness is in ± 1HRC~2HRC less than. The long way of workpiece retains the ability of tolerancepublic errand precision than also can affecting a machine tool. Lathe of typical type of fixed the head of a bed is general need not tailstock, it is to growing diameter to compare 5: 1 to 6: When the flexible simple work of 1 is machined, can achieve quite strict precision. The T- with the before losing horn of the hardness as a result of workpiece, cutting tool and indispensible place of cutting horniness stuff pours arris, make cutting tool pressure quite great, consequently, when workpiece does not have tailstock bearing, must be in the long way of workpiece than limitation 3: 1 to 4: 1. Of course, is what this limitation wants to follow work different and change? ? That is to say, the capable person that lets workpiece qualitative, hardness and right bright and clean spend and precision asks and advocate. Tailstock can have certain effect, but it is not the panacea that solves all problems. For example, the tip does not stop in case the quiver of the workpiece of diametical 25mm, long 300mm. To this kind of workpiece, you can use the method of grinding only. Should assure to compare 0.

The tolerancepublic errand precision with stricter 005mm, use grinding craft to also had been compared. Although say turning of oil hard data cannot replace grinding completely, but it can be replaced quite big one part, especially when the long way of workpiece is more complex than lesser, appearance, hard turning is worthy of be is good with a kind when car generation grinds technology.
