What is Custom Machining?

Custom machining often refers to custom CNC machining services provided to meet the specific requirements of customers for piece-parts, or component parts. Most of the custom machined parts are made with CNC machines. With the development of manufacturing techniques, design software, transportation, and shipment, custom parts for specific uses are becoming more and more common among CNC machining parts orders. Custom CNC machining uses CAD files and converts them to the programmed languages for instructing the actions of machines. Generally, the customer’s requirements are specified by a detailed 2D/3D drawing with additional notes or markings. Custom machining involves various forms of technologies and machinery, from traditional lathes to 5-axis CNC machining centers to Swiss-type machines, and from rapid prototype to plastic machining to metal machining. Normally, CNC milling and CNC turning can implement a lot of features. But some custom machining jobs do not require CNC equipment at all.

When and Why Custom Machining is Needed?

In some cases, when designers create a new production project, and a single component of the product cannot be purchased from the supplier or not sold at a reasonable price, custom machining is required. Completely ordinary parts that happen to have special requirements may also need custom machining. These components may be simple or just new inventions, such as gears of non-standard sizes or materials, custom adapters, text engraving, etc. When the part is not sold as an off-the-shelf item or catalog, custom machining is needed to customize it. Depending on the shape, size, and other requirements of the custom machined parts, the production might be done using a lathe, a milling machine, a drill bit, a stamping press or other equipment. Quality CNC custom parts can be made in high efficiency from their digital files because there is rarely a minimum order quantity and the setup time is short.
