What is Precision CNC Machining and What Are Its Advantages?

Create Time: 20-12-2017

Precision CNC machining involves cutting raw materials into products by cutting the redundant parts specified by computer-aided design (CAD) or computer-aided manufacturing (CAM) blueprints. Machinists use this process in different manufacturing processes and different materials.

Because precision CNC machining involves different processes, different equipment is needed to make it work. In some cases, these tools are placed on a machine. And the operator only needs to start and stop the process. While sometimes, the tools must be placed on different machines, and the machinist must move the workpiece/raw material from one machine to another.

Ⅰ. What is precision CNC machining?

Before using precision CNC machining to manufacture any products, a CAD or CAM program must be used to make a blueprint for the product. These programs produce very detailed 3D contours, and precise machining processes must be followed to successfully replicate products. From toys to medical equipment, automobiles, or space shuttles, any product with parts requires precision CNC machining. This process uses computer numerical control (CNC) equipment, using cutting, milling, turning, and electrical discharge machining to achieve the final product.

Although the process requires the supervision of a skilled mechanic, the machine can do most of the work automatically. Computer-aided design (CAD) software creates the design, and then computer-aided manufacturing (CAM) software converts it into machine manufacturing instructions. The final post-processor software encodes instructions into information that the machine can understand. The operator then loads the instructions into the CNC equipment to start the manufacturing.

Ⅱ. What are the advantages of precision CNC machining?

Reduce production costs: In terms of price, precision CNC machining is a viable method, especially if you want to manufacture a few to a hundred parts. Compared with injection molding, precision CNC machining requires less upfront cost due to the cost of manufacturing molds.

Speed improvement: Compared with injection molding, CNC machines provide higher speeds. Unlike injection molding, the machine can take months to make molds and ensure that the parts meet tolerances so that precision CNC machining can produce parts in a few weeks.

It allows for fast and cost-effective prototyping: With precision CNC machining services, your prototype production is more efficient. This is because CNC can use lots of cost-effective materials, so you don't have to spend a lot on prototypes. Of course, when prototyping is faster, the entire production process will be faster.
