Human body knee joint is false body application case and treatment requirement are opposite as people the unripe material resources of knee joint learns to study ceaseless development, knee joint false body designs a concept to be updated ceaselessly, operation of displacement of artificial knee joint is mature with each passing day also, operation effect obtained clinical affirmation gradually. Current, art of displacement of artificial complete knee joint is considered as cure eventually one of operations with evening or serious the the most effective, most successful gonitis. While this operation has higher demand to applying the operation standard of art doctor, the quality stand or fall of artificial knee joint and installation position, the effect of adversary art is having very big effect, matter to the patient's health directly. In art of artificial and articulatory displacement, the application of false body is an indispensable link. However, in art of displacement of nearly 10 thousand when finish in our country artificial knee joint, major false put oneself in another's position comes from foreign manufacturer, homebred holiday system is basic it is mimic, the technology contains Troy low, and the price however still on the high side, the variety that can offer an alternative is not much also, product quality and foreign manufacturer presence are larger difference, so, partial product can count foreign import only. It is the development that what restricted our country artificial joint so, is those who make homebred holiday body and difference of foreign developed country such big? Well-known, a little artificial and joint appearance is very complex, outline precision and surface are bright and clean degree of demand is extremely high, the ability of 5 axes all-purpose grinder that has high accuracy only achieves his to ask, so the key of the problem depends on artificial joint is the treatment on center of 5 axes grinding, the precision of center of 5 axes grinding and efficiency affected the quality of the product and cost directly, the ability of 5 axes grinder that only accurate treatment method adds high accuracy makes high quality product, and the health that high quality product decided a patient. Nicety of accurate grinder implementation machines the accurate grinding machine that accurate machine tool has Dirk more than 50 years to produce classics produce the expected result, its unique vertical structure is the innovation with tool grinding revolutionary domain. Well-known, when vertical principle undertakes machining, the machine tool can bear most load, workpiece is cantilever condition no longer, avoided the generation of integrated error below gravitational action, eliminated hang the machining error that extends length to bring, make workpiece gets power mediumly in treatment more reasonable. S22P of grinder of heart gram nicety takes 8 work oneself emery wheel library, can use the emery wheel with all sorts of different figure, dimension, granuality and qualitative material at the same time, can satisfy the treatment requirement with different and phyletic norms, appearance and qualitative material, hold clip requirement of achievable thick finish machining, raise manufacturing efficiency and product precision greatly. Main shaft electric machinery is the main shaft of tall accurate report that deserves to have independent water-cooling system, undertake to main shaft electric machinery constant temperature cools directly, protect main shaft, assure the tall life of main shaft, the machine tool can fall in higher rotate speed judge torque output, ensure of grinding task finish smoothly. System of feedback of complete closed circuit of feet of 5 axes grating, make sure every dimension does not have the product accurately by accident. Dirk's engineers are having very rich treatment in domain of medical apparatus and instruments classics check, with artificial knee joint treatment is below exemple, dirk the company machines the check of precious classics of the respect and everybody to share in medical apparatus and instruments. The treatment of knee joint of work of artisan of industry of treatment of human body knee joint can divide roughly for the following measure: (1) CAD 3D builds a model (STEP, IGES, etc. ) : Can build the three-dimensional model of artificial knee joint through the 3D software such as UG, Solidworks, Pro_E. (2) CAD-CAM: Know place of machine tool of translate into of data of CAD 3D model other sport contrail, corresponding G code is generated inside the machine tool. (3) measure: Will shape beforehand semifinished product and clamping apparatus load a machine tool, what allow through essence of life is online and automatic survey a system, measure the seat that gives workpiece and clamping apparatus automatically. (4) outline of thick mill profile modeling: The 3D model that builds before the basis, cross thick mill via above all, eliminate major surplus for kibble; Heart gram machine tool provided system of feedback of feet of grating of 5 axes complete closed circuit, resolution of highest and linear axis can be achieved 0.
0001mm, resolution of runner shaft coming back can be amounted to 0 breathtaking.
00005 ° , through essence of life accurate 5 axes linkage is controlled, when assuring milling accurately size of each place surplus, ensure whole outline surplus is even. Cutting tool norms: φ 10mm-R2, milling cutter of 4 blade R. Cycle time: Make an appointment with 5min. (5) thick / essence of life grinds outline to amount to dimension requirement: Those who pass emery wheel library cooperate, those who finish emery wheel of thick, essence is online change, outfit clip can finish thick, essence to grind treatment at the same time, avoided to repeat the error that hold clip, more accurate control essence grinds surplus. System of wheelhead independence refrigeration makes sure the machine tool is in work for long continuously next temperature are constant, the machine that because temperature changes,avoided to cause expands. Marble base expands the vibration of the machine tool in grinding process and heat fall to lowest, the assurance of utmost product precision and the consistency that batch produces. Norms of kibble emery wheel: D181 of φ 125mm R5 granuality, Ñ annulus time: Make an appointment with 5min; Essence of life wears emery wheel specification: D64 of φ 125mm R4 granuality, cycle time: Make an appointment with 20min. Classics crossed a few simple measure to turn wool preform into a delicate artificial knee joint, it will help a life stand afresh rise, probably the new life of double leg recovery that she won't know to artificial knee joint is how to help her forever, but before the life in health, these already appeared no longer important.
