What Is CNC Machining?
CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.
CNC machining is a subtractive manufacturing process where raw material is removed with a variety of precision cutting tools to make a part or product. Advanced software is used to control the equipment according to the specification of your 3D design. Jasonmould’s engineers and machinists program the equipment to optimize cutting time, surface finish and final tolerance to meet your specifications. We use CNC machining not only to manufacture parts and prototypes but also to make mold tools, which can be used for our plastic injection molding or pressure die casting services.
Advantages Of CNC Machining
CNC machining is great to meet a range of your product development needs. Here are some of the benefits of precision machining:
Quick removal of large amounts of metal material
Highly accurate and repeatable
Suitable for many different kinds of substrates
Scalable volumes from 1 to 100,000
Low investment in tooling and preparation costs

CNC Turned Parts
Our CNC lathes enable high speed and quality turning of both plastics and metals. The turning process allows for complex external geometries and internal bores to be generated. Our turning capacity is available for prototypes through to low-volume production.
CNC Milled Parts
CNC milling is used to apply a machined surface finish on plastic or metal, or for creating complex 3D shapes. We use domestic and imported 3, 4 and 5-axis CNC machining centers with quick-change tooling, programmed using advanced Delcam software.
EDM / Wire EDM And Surface Grinding
EDM (electrical discharge machining) is a method for cutting holes, pockets and other shapes into hardened steel, as well as imparting a surface texture to the internal cavities of mold tools. A sacrificial electrode in an electrolyte bath discharges a high-powered electric spark to erode very hard materials that would be difficult or impossible to do with any other method. Square pocket holes are often created with this method. With wire EDM, a wire is continuously fed between two spools. When electrically charged, it’s able to cut through hardened tool steels quickly and accurately.
At Djmolding, we also offer surface grinding services. When surface grinding, the workpiece is held stationary on a horizontal plate. The surface grinding wheel is computer controlled to abrade the workpiece to a precise depth.
CNC Machining Tolerances
Our general tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics, DIN-2768-1-medium. Tolerances are greatly affected by part geometry and type of material. Our project managers will consult with you on every part of your project and will seek to provide the highest degree of precision possible.
CNC Machining Materials
We work with a wide range of plastic and metal materials including magnesium, steel, aluminum, brass and titanium to make tooling for plastic injection molding and pressure die casting or to make parts for rapid prototypes and low-volume production. In addition to our stock list, we can provide you with customized raw material as required.
