Benefits of CNC Prototype Machines

Dec 7th 2015 at 12:46 AM

CNC machining enables the production of high quality, highly accurate parts with a very fine finish. With strict quality control clients can expect durable and reliable parts.

CNC machines automate the functions normally carried out by machine tools such as lathes and mills. These CNC machines are programmed using sophisticated CAM and computer software to substitute manually operated levers and hand wheels. CNC machining centres can effectively process a wide variety of non-ferrous and ferrous metals as well as plastic materials.

First, the raw material is placed into the machine where it is held by a vice, fixture or chuck. After the material is loaded and secure, the cutting tools cut off excess material giving the final part its required shape. These machines are highly effective manufacturing solutions. This can be attributed to their programmability which gives them the accuracy, repeatability and high speed needed in a demanding market. These machines can produce quality functional prototypes as well as production parts.

CNC Machined Parts

CNC machining can be used both for one offs and also the production of hundreds of parts. It can be used on a wide range of different materials ranging from stainless steel, mild steel, aluminium, plastics, brass to magnesium and zinc. CNC machining handles services such as turning, precision surface grinding, milling, EDM, and wire spark erosion to produce highly effective precision-machined parts. Clients’ projects are first discussed with the engineering department to come up with the most appropriate material and CNC process before production begins. QA/QC protocols thoroughly inspect parts before, during and after production. Original certificates for the materials used in the project can be provided at a customer’s request.

Milled Parts

CNC milling enables the accurate creation of 3D and 2D shapes with a high standard finish. The CNC milling operations are first programmed offline with the help of Delcam Powermill software. This job of tooling pre-set enhances accuracy as well as ensures speedy production. Most CNC machines and milled parts enable you to machine parts accurately using a variety of stock material.

Turned Parts and Tolerances

The CNC lathes ensure fast and quality turning of metals and plastics. During the turning process, complex external geometries, as well as internal bores, are generated. Turning capability of the machines can handle one offs and also batch production. The CNC machines have a metal tolerance of DIN-2768-1-fine while the plastics plastic tolerance is DIN-2768-1-medium. Tolerances depend on both geometry and also the type of material used. Project managers consult with each clients on every project to determine the most appropriate material to use.

Finishing Process

Usually, a wide range of finishing services for the machined parts is provided. These services in CNC prototype machinesinclude surface grinding, honing, knurling, printing, and painting. If you are looking for CNC prototypes or vacuum cast parts, the author of this article recommends HLH Prototypes.
