Automatic Tracer Lathes and Milling

Automatic Tracer Lathes and Milling

 Cnc machining Since surface roughness depends greatly upon material turned, tooling, and fees and speeds employed, minimum tolerances that can be held on automatic tracer lathes are not necessarily the most economical tolerances. 

    Is some case, tolerances of ±0.05mm are held in continuous production using but one cut. Cnc machining   Groove width can be held to ±0.125mm on some parts. Bores and single-point finishes can be held to ±0.0125mm. On high-production runs where maximum output is desirable, a minimum tolerance of ±0.125mm is economical on both diameter and length of turn.

  Milling  

  With the exceptions of turning and drilling, milling is undoubtedly the most widely used method of removing metal. Well suited and readily adapted to the economical production of any quantity of parts, the almost unlimited versatility of the milling process merits the attention and consideration of designers seriously concerned with the manufacture of their product.  

 As in any other process, parts that have to be milled should be designed with economical tolerances that can be achieved in production milling. Cnc machining   If the part is designed with tolerances finer than necessary, additional operations will have to be added to achieve these tolerances——and this will increase the cost of the part.
