CNC machining shops typically stock bars with diameters ranging from 6mm to 150mm. Before machining, PEEK must be stress relieved by an annealing process. This is to prevent the formation of surface cracks and internal stress due to heat generated during cutting. In long-time PEEK machining, additional annealing procedures are required, such as an annealing procedure before roughing, and a second annealing before finishing to eliminate the possibility of crack formation. The cost factor for PEEK CNC machining is 0.9 compared to steel 12L14.

CNC machining is the ideal manufacturing option for medical devices. Manufacturers who specialize in CNC machining can provide economical solutions and optimize production costs for even the most complex medical components and assemblies. The process can machining very accurate medical prototypes in a short time, compatible with a variety of plastics, metals and other special materials. While most metal or plastic components must meet the requirements of ISO 9001 quality management, medical prototypes and components must also meet more demanding standards.
CNC machining can manufacture the part with tight tolerance requirements and fine parts of various metals or plastics, and is one of the best machining methods for custom parts and prototype production. During CNC machining, raw material is selectively and precisely removed to produce the part that approximate the final shape. This machining process is also commonly referred to as subtractive manufacturing. As the CNC cutting tool continuously removes raw material during machining, visible cutting tool marks will be created on the surface of the part. For the definition of finish of these cutting tool marks, we call it the surface roughness of CNC machined parts and divide it into various roughness grades.
In addition, for CNC machining precision metal parts, in order to meet the purpose of wear resistance, corrosion resistance, insulation, decoration, improving service life or adding other special functions, we generally adopt specific finishing services to meet the requirements. For the surface treatment of customized metal parts, the common techniques we see are anodizing, electroplating, electrolytic polishing, passivation, brushing, sandblasting, painting and powder coating, etc.
A CNC machining shop is usually a small but professional manufacturing facility dedicated to delivering custom parts and prototypes in a short time.

General speaking about the injection mold is a steel mold. But its machining cost is expensive and the lead time is long. If only small volume or medium volume parts are required for manufacturing, aluminum molds have become the first choice.As technology advanced continuously, aluminum has also become a popular choice for mass production. What is the difference between aluminum mold and steel mold? This article will introduce the difference between the two in details.
Tolerance is an acceptable range of deviations from expected values for dimensions determined by the designer based on the shape, fit and function of the part. CNC machining is very precise, but not perfect, it is impossible for two parts made using the same manufacturing process to make the same part with the same exact dimensions even on the same CNC machine. If tighter tolerances for CNC machining are required (eg +/- .002”), the more precise information of the critical dimensions must be marked on the drawings.
