Precision Turned Parts Precision turned parts are parts that have been machined with extremely tight tolerances. The majority of precision turned parts are formed through a simple yet important process known as CNC turning. CNC stands for computer numerical controlled, meaning that a software program is controlling the machine as opposed to the control of a human.

With such wide-ranging applications, turned parts are able to serve industries such as electronics, automotive, appliance, HVAC, marine, medical, telecommunications, petroleum and optical. Precision medical parts are intricate components that are formed with tight tolerances. They are composed from sanitary-grade materials such as titanium and stainless steel to ensure adherence to medical standards.

With new turning processes that allow for design capabilities and structural benefits, which cannot be cost-effectively reproduced with any other manufacturing method, turned parts offer exceptional precision depth and dimension.

Precision turned parts are created through CNC turning which can be accomplished using CNC screw machines or CNC lathes. CNC screw machines are multi-spindled, enabling the machining of several parts simultaneously, while achieving high production rates. CNC machine turning begins when a round, square or hexagonal blank is attached to the spindles' spring collets.

Next, this blank begins to spin as multiple automated cutting, drilling, notching and knurling tools attached to the machine work the blank into precision turned parts by shaving away excess material, smoothing and drilling. The main drive shaft of a Swiss screw machine provides power to the machine bed's lead work shaft and controls the two front cam shafts.

The machine motor, located at the base of the machine, is the central power source for all operations and will vary in horsepower, depending on the size of the machine, speed and stock to be machined. A CNC lathe is a computer-controlled machine tool with the ability to shape precision turned parts by holding and rotating a blank, also called a workpiece, on a single spindle while a drill bit performs the cutting action.

A more recent development, CNC lathes are rapidly replacing older-style lathes since they are generally considered to be easier to set as well as operate since a less intimate knowledge of the lathe is required. Typically, precision turned part manufacturers have the operator and the setter as the same person.
