High accuracy and manufacturing process dependability are the demand that produces to product of medical apparatus and instruments, also be the requirement that the supplier that supplies equipment and machine tool equipment to producing manufacturer to medical apparatus and instruments raises at the same time. The guide that muller of embedded content polish uses the human body of Otec company newest production can bear very tall active force, thereby more compensate the parallelism alignment error between slideway conveniently. 70% right-and-left workers of Otec company are engaged in the research and development of accurate polish equipment and production, agree with to get the research and development of the accurate polish device that uses inside the country and production in technology of medical apparatus and instruments especially. The user of this company nots from the benefit in the union of special machine tool device and abrade polish engineering technology shallow. Leader Mr Helmut Gegenheimer of Otec company says: "For example, muller of the SF that company newest research and development produces polish (graph 1) it is special in the light of human body embedded substance appearance is machined and research and development is designed and production makes. " graph 1 accurate polisher can make can use the spare parts with manual abrade polish to finish in very short time only up to now from go burr, grinding, abrade to the full treatment of polishing Mr Gegenheimer is when the worry that speaks of company user say: "The surface of manual operation machines the price that promoted medical apparatus and instruments the product substantially, because of this company research and development technology of accurate and abrade polish. " such, the part that uses manual and abrade polish all the time up to now is OK also now finish in very short time from go burr, grinding, abrade the full treatment to polishing. Accurate polish equipment most agree with with outline appearance to what machine hard complex part undertakes abrade with polishing, at the same time it also can machine the spare parts of plastic perhaps like titanium, pottery and porcelain material. The new-style SF nicety that control Mr Gegenheimer of micron class precision is about to leave factory in the introduction says when polisher: "The accurate polisher that the user uses a firm will if the cobalt such as joint of hip joint, shoulder is chromic,be machined alloy human body is embedded content. Can make after the exterior quality that improved these embedded thing patient activity more freely, and the attrition force of the generation in the activity is smaller. " this nicety polisher can finish length of the biggest treatment to amount to 400mm, the greatest weight amounts to the grinding of the spare parts of 10kg and polish. Contain cave structural spare parts, for example the shoulder is articulatory, also be another kind of typical spare parts that this accurate polish function machines quite. Mr Gegenheimer is introducing the when producing a course say of new-style and accurate polisher: "Machining what use when this kind of spare parts is the special type clamping apparatus that has high speed main shaft, be in grinding fluid perhaps completes accurate treatment in polishing fluid. " be spent by the rotate speed coming back of treatment spare parts can be as high as 8000r/min. The athletic process that abrade polish machines is controlled by orbit, because this can be machined well and truly,go out cave of place each are nodded. The structural design of the machine tool assures to be able to adjust grinding fluid well and truly or the treatment angle of polishing fluid, the cutting that achieves micron level machines control. "Full treatment uses a few hours only at most! " when the manufacturing efficiency that speaks of this one equipment, this industry leader is proud ground say. Technology of SF accurate polish is based on grinding fluid or over the foundation of velocity of flow with polishing very tall fluid, accordingly a few the smallest, special hard the area of bring into contact with and groove also can be machined well and truly come out. The surface roughness of spare parts of treatment of facilities of this one treatment (Ra) can achieve be less than 0. The level of 01 μ M. The very high rotate speed when slideway made sure steady treatment work rotates can produce very large active force. For example, the slideway of the machine tool is in the load that type can be pounded every time when fluid of grinding of spare parts immerge and polishing fluid. Dr.
The stability that the slideway of Translide series NSK that Tretter company research and development produces assured to new-style and accurate polisher produces a course and dependability (graph 2) . Graph have the aid of of slideway of 2 ball drive at special inside seal unit and the sealed layer with bottom slip, make its OK the guide that uses this kind of high strength in the environment that has dust is having clear advantage, mr Gegenheimer says: "Its structure can compensate parallelism alignment error and the high error with planar machine tool well. " its parallelism has 60 μ M only greatly most on 100mm length. Such, the high error that allows on the slideway of whole length 500mm can amount to 500 μ M only. Additional, this kind of slideway is contained special inside seal unit, and slideway slip bottom also has seal unit, because this this nicety polisher is OK,the installation in the environment is produced in what have dirt and use.
