Karakteristika for CNC Hard track

IMG_20200903_120017

Most factories understand hard rails and linear rails: if they are used to make products, they buy linear rails; if they are processing molds, they buy hard rails. The accuracy of the linear rails is higher than that of the hard rails, but the hard rails are more durable. cnc machining part

Hårde sporegenskaber
1. Fordele ved CNC-bearbejdning af hårde skinner:
1. Den kan modstå større belastninger og er velegnet til skrubbearbejdning af værktøjsmaskiner med stort værktøjsvolumen og stort tilspænding.
2. På grund af styreskinnens store kontaktflade kører værktøjsmaskinen mere jævnt, hvilket er velegnet til værktøjsmaskiner med højere krav til maskinvibrationer, såsom slibemaskiner.
2. Ulemper ved hard track:
1. Materialet er ikke ensartet. Fordi det generelt er støbt, er det nemt at frembringe støbefejl såsom sandindbygning, porøsitet og løshed i materialet. Hvis disse defekter findes på styreskinnens overflade, vil det have en negativ indvirkning på styreskinnens levetid og værktøjsmaskinens nøjagtighed.
2. Bearbejdning er vanskeligere, fordi denne type styreskinne generelt er forbundet med hoveddele af værktøjsmaskinen, såsom basen, søjlen, arbejdsbænken og sadlen. Derfor, i processen med forarbejdning, er dets form og positionstolerancer, ruhedskrav og aktualitet Bearbejdning, bratkøling og andre processer vanskelige at kontrollere, hvilket resulterer i, at forarbejdningskvaliteten af ​​delene ikke kan opfylde kravene til montering.
3. It is difficult to assemble. The word "assembly" means to assemble as well as to assemble, and the matching process is a process of combining technology and physical strength. It cannot be done by ordinary workers. It requires a relative quantity of skills. CNC machining & Milling machine tools can only be completed by assembly workers who are quite sure of the overall accuracy. At the same time, it also needs to be equipped with a blade, flat ruler, square ruler, square ruler, dial indicator, dial indicator and other corresponding tools to complete it.
4. The service life is not long. This can only be done in relative terms. Under the same maintenance and use conditions, the service life of common hard rails is less than the service life of linear rails, which is very much related to their movement methods. In terms of friction, the hard rail runs under sliding friction, while the linear rail runs under rolling friction. In terms of friction, the friction on the hard rail is much greater than the friction on the linear rail, especially in lubrication. In the case of insufficient, the friction of the hard rail is even worse. machined part
5. Vedligeholdelsesomkostningerne er for høje. Vedligeholdelsen af ​​den hårde skinne er langt større end vedligeholdelsen af ​​den lineære skinne med hensyn til sværhedsgrad og vedligeholdelsesomkostninger. Hvis skrabemarginen er utilstrækkelig, kan det involvere demontering af alle de store dele af værktøjsmaskinen. Genhærdning og bearbejdning, eller endda genstøbning af den store del, og trådmåleren skal kun udskiftes med den tilsvarende trådskinne, hvilket ikke vil have stor indflydelse på brugen af ​​relaterede store dele.
6. The running speed of the machine tool is low. Because of the way of movement and the friction that the hard rail bears is too large, it usually cannot bear the running speed too fast. This is contrary to the current processing concept. In particular, many factory workers do not have the corresponding maintenance knowledge of machine tools. Many times they only know the use of machine tools, but to a large extent ignore the maintenance of machine tools. The maintenance of machine tool tracks is the most important thing. Once the track is not sufficiently lubricated, It will cause the track to burn or wear out, which is fatal to the accuracy of the Precision CNC machined. aluminum part
