Rapid CNC Machining Services
At Holy Precision, we use advanced equipment to offer you a variety of CNC machining services including milling, turning, EDM, wire EDM, surface grinding and much more. Using our imported 3, 4 and 5-axis CNC machining centers, our skilled machinists can make turned and milled parts using a wide range of plastic and metal materials. Our CNC machining abilities also complement our 3D metal printing service making us a great one-stop-shop for your advanced designs.
What Is CNC Machining?
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. Our team of 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 one to 100,000
·Low investment in tooling and preparation costs
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 Holy Precision, we also offer surface grinding services. When surface grinding, the work- piece is held stationary on a horizontal plate. The surface grinding wheel is computer controlled to abrade the work-piece 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 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.
CNC Machining Quickfacts
Why choose CNC machining?CNC machining is a fast, accurate and versatile solution for making production-quality parts in any quantity, without the need for investing in hard tooling or expensive set-ups.
What raw materials can I use with CNC machining?Finished parts can be made from many types of easily available stock metals including mild and stainless steel, aluminum, brass, copper, magnesium and titanium. We can also machine rigid plastics.
What tolerances can I achieve with CNC machining?We routinely produce parts to .05 microns, which is suitable for the majority of commercial and industrial applications. Closer tolerances are only advised for critical applications – they will take longer to produce and will increase processing costs.
