Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material removal process. Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites. A person who specializes in machining is called a machinist. A room, building, or company where machining is done is called a machine shop. Machining can be a business, a hobby, or both. Much of modern day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes,
and other cutting machines.The three principal machining processes are classified as turning, drilling and milling. Other operations falling into miscellaneous categories include grinding, shaping, planing, boring, broaching and sawing.

- Turning operations are operations that rotate the workpiece as the primary method of moving metal against the cutting tool. Lathes are
  the principal machine tool used in turning.

- Drilling operations are operations in which holes are produced or refined by bringing a rotating cutter with cutting edges at the lower
  extremity into contact with the workpiece. Drilling operations are done primarily in drill presses but sometimes on lathes or mills.

- Milling operations are operations in which the cutting tool rotates to bring cutting edges to bear against the workpiece. Milling machines
  are the principal machine tool used in milling.

- Grinding is the final category of machining techniques. This relatively simple process involves using a stone-grinding wheel to shape or
  polish metal. This technique may be used to sharpen a metal hand tool or to give metal building materials a satin finish.

- An unfinished workpiece requiring machining will need to have some material cut away to create a finished product. A finished product
  would be a workpiece that meets the specifications set out for that workpiece by engineering drawings or blueprints. For example, a
  workpiece may be required to have a specific outside diameter.

- Miscellaneous operations are operations that strictly speaking may not be machining operations in that they may not be swarf producing
  operations but these operations are performed at a typical machine tool. Burnishing is an example of a miscellaneous operation.
  Burnishing produces no swarf but can be performed at a lathe, mill, or drill press.

- More recent, advanced machining techniques include electrical discharge machining (EDM), electro-chemical erosion, laser cutting, or
  water jet cutting to shape metal workpieces.

Machining is just a single part of a larger manufacturing process. Metal manufacturing begins with design, then proceeds through manufacturing and production. Machining may be used to shape the metal and create the object, or may serve only as a method of finishing the metal to give it the desired appearance. After machining is complete, the object must be finished and assembled before it is ready for sale.

We will manufacture any machined component part to our customer's drawings and specifications.
