DSI Machines PartsCNC metal machining is an automated manufacturing process whereby the factory metal machining tool is operated by pre-programmed software. The acronym CNC comes from the term "computer numerical control." DSI offers both metal and plastic CNC machining services. With DSI's CNC machining, you get exact control over complex machining and factory tool movement such as speed, rate of feed and coordination. CNC allows software to carry out repetitive, predictable tasks rather than rely on human operators. The results - consistent, precise, and accurate CNC metal machining parts production.


Milling Machining ServicesDSI employs 3 axis, 4 axis, and 5 axis CNC milling machines with both vertical and horizontal milling capabilities. DSI gives customers a full range of plastic or metal CNC milling options necessary to achieve their precision and tolerance objectives. With a staff of highly-trained CAM programmers utilizing Mastercam, GibbsCam and Autodesk Inventor, DSI has the resources to rapidly produce complex milled parts. See more information about our CNC Milling Services.


Turning Machining Services

What is CNC Turning?
CNC Turning is a computerized machining process in which a plastic or metal working piece is held firmly in place while being rotated. A turret that holds the cutting tools and controlled by the computer is then fed into the piece to remove material and shape the finished part. The turret can hold multiple tools allowing many options of complexity when machining parts. DSI turning centers employ swiss CNC turning machines with up to 13 axes. DSI has swiss lathes, twin spindle, twin turret, multi-plex, single turret/single spindle, single turret/twin spindle, and four lathe machines equipped with bar feeders. DSI is equipped to handle any of your lathe or machine turning needs. Our staff of highly-trained turning machinists and Swiss machinists can work with you to ensure your part exceeds all expectations. Contact DSI today to learn more about our CNC turning service and how we can help you make your turning project a success.


Surface GrindingSurface Grinding is a metal machining process that uses a rotating abrasive metal-cutting grinder wheel on material to give it a more refined flat-finish look. It is used to remove a layer of oxide or impurities or to give the material a certain type of functional surface. DSI offers customers various machining grinding options including straight line and random-arc capabilities as well as multiple hand grinding capabilities. Contact DSI for more specific information about your metal-machining grinding needs.
