Can repeating fixed position of workpiece is the crucial place of implementation is small expensive precision work. On standard system, can repeat precision (identical tray and unified clamping apparatus) it is 2 μ M about. And one kind is replaced now model the system can ensure the precision of transhipment of through cargo that is 1 μ M on average. Identical tray is on all sorts of different clamping apparatus, precision of its transhipment of through cargo is 8~15 μ M normally. Although this kind of precision is already enough to flow of a lot of treatment, but in the treatment in high spirit little work, this kind of precision cannot have satisfied a requirement. The machining error that asks here is less than 5 μ M. In producing segment (from production equipment arrives measure equipment) , when using system of standard type clamping apparatus to have transhipment of through cargo, with respect to the biggest machining error that had been achieved or exceeded place to allow, and the treatment that has no real significance to go up right now is wrong. Be aimed at the demand that can repeat little work of treatment high spirit, hirschmann company offers a kind of μ - Prisfix outfit blocks a system. The technical equipment of this company can ensure precision of average transhipment of through cargo achieves 1 μ M to be below in small treatment, the blueprint public errand that is less than 10 μ M is not minority, accordingly, treatment is completed in wanting workpiece to be able to hold card in only and if equipment can satisfy accuracy class to ask, also won't face big challenge. If workpiece must be in,a whole production finishs the sentence of treatment in link, criterion because arrive from equipment equipment or the transhipment of through cargo that measure equipment to the standard from equipment, allows error is exceeded very quickly. By the accurate μ of research and development of Hirschmann company place - Prisfix outfit blocks a system, can come true to arrive from clamping apparatus the precision of is less than 1 μ M average transhipment of through cargo of clamping apparatus. The example below can clarify again its are using medium sense actually. μ - use range and measure technical domain what Prisfix installs calorie of system not only, cover the field such as turning, grinding, milling and laser beam machining however. Because this construction of system is compact, the diameter has 50mm only, have 42mm only to the height of the brim on tray, because this is OK and safe, reasonable,process little work with high accuracy ground. Hold card in the light of workpiece, also can offer 50mm diameter and contain Kong Yigu of 4 M4 whorl to decide the standard type tray of workpiece and device. The precision of transhipment of through cargo that is system of 10 μ M and outfit card in public errand of general assembly blueprint is the circumstance of 8 μ M to fall, 80% what install calorie of system to be able to use up blueprint public errand only. Reach plus a few inevitable machine tools, cutting tool and transhipment of through cargo measure the error that waits for a respect, allows common difference is met be exceeded very quickly. Through using μ - Prisfix outfit blocks a system, the tolerancepublic errand surplus that has 9 μ M can leave treatment exercise itself. Tolerancepublic errand loss is only 10% (next graphs) . System of card of standard type outfit and μ - the public errand that asks in the light of blueprint public errand between system of Prisfix outfit card alleviates comparative: Use this kind to replace model program of the technology that hold card, tolerancepublic errand loss blocks a system to still can pass the H1 that newest research and development comes out for 10% this outfit only.
1005CC μ - Prisfix-Center-Clamp tray has complement. Vice of a miniature is set inside this tray, can place the circular work that holds 8mm diameter and 22mm quadrate workpiece. Be in to the diameter under 15mm, be the same as the work with circularity extremely high demand, can use the calibration clip that has won patent to maintain component. This kind of new-style clip holds what component can ensure place needs already to be the same as circularity, OK still workpiece swing limits control is in be less than 1 μ M. All components all are used anticorrosive stainless steel is made, pneumatic clamping apparatus accomplishs whole sealed (IP68) support function of control component and cleanness of air current of Hirschmann Center Clean through a clip, can undertake cleanness to centering protruding ear and Z scaleboard. A kind of clip that realizes monitoring through enquiring push rod position comes holds monitoring function to also can offer an alternative. In the meantime, tray all sets to be able to be used at the interface catching claw that carries automatically. Can repeat what what narrate here and precision of transhipment of through cargo all already by the inspection agency of confederative physics technology that is located in Braunschweig (PTB) in carry an item undertook examining mixing inside frame approve.
