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.

Benefits of CNC Prototype Machines

Prototype Machining as the name indicate is the process where prototypes or models are fabricated using automated cutting machines to cut away from solid pieces of metal and plastic to create a prototype or production part.

With computerized solutions being used in almost every sphere of life, it has its impact of the machining arena too. And accordingly, CNC machining is fast replacing conventional machine prototyping. So, what does CNC stand for? It means 'computer numerical control' machining and it allows for computer controlled machining. With CNC prototype machining, you can expect greater levels of efficiency through higher levels of automation processes. 

These machines consist of a high-speed machine head that takes care of the three-dimensional movements during the process. Moreover, the head is equipped with a chuck where the series of cutting tool bits are systematically inserted. The head plays a vital role in the entire mechanism. It moves over a block of model material that slowly removes the layers from the machine until the finished prototype is revealed. This is how a basic prototype is designed.

While detractors of this process accuse it of being too expensive for developing models, and replicas, its advocates feel that faster and accurate results negate all that. It also reduces sufficient workload and prevents errors related to conventional methods of prototype machining. Moreover, due to automated controls, expenses on employing extra manpower reduced significantly. 

Indeed, some CNC machines are so efficient that you can in fact leave it unattended and put your focus and effort on some other tasks. Hence, you can do multitasking with these machines. Ultimately, this also reduces unwarranted accidents, as now you don't have to worry about worker safety with automated controls that work on their own, once you switch the 'on' button. 

The best thing however is that this with CNC prototype machining, you can get prototypes just anytime. As these machines work 24X7, you do not have to worry about worker fatigue and yet gets faster results with zero errors. Moreover, unlike manual machining every product in this type of computerized machining are exact replicas of each other. There would not be any variations, which usually happen with traditional and manual production methods. 

Now, you would ask, 'what about customized products, if all the products are replicas of each other?' CNC prototype machining has answers for this as well. CNC machines are flexible; you can program these as per your requirements and specifications to get the prototypes that suit your ideas. 

You should choose a CNC prototypes machine service that is suitable for your project.
