There are literally hundreds of types of CNC turned parts created daily for dozens of uses. The five main categories that these parts are created for include plumbing, automotive, hardware, construction and home improvement needs. All of these applications require absolute precision for the parts used in a project. Discussed below are some of the most important uses and factors that go into the creation of these items.
In the plumbing industry, pipes are created with threaded ends to create a tight fit. The CNC turned parts for this industry include materials such as plastic, PVC, copper piping and other cast alloy materials. Threaded ends must be precise to prevent water leaks, bust pipes and damage to a home or business’ structure.
Fittings used for connecting joining pipes or for the creation of a curve must also be threaded in a precise manner. The purpose for this is to create a tight seal from pipe to pipe.
The automotive industry uses nuts, bolts, fittings, housings and a variety of other pieces that require a precise construction. CNC turned parts for these applications must follow absolute specifications to ensure vehicle safety. There are no shortcuts for this application given that one simple mistake or improper measurement can cause a vehicle malfunction or accident.
Home Improvement Pieces
CNC turned parts are used for home improvement pieces and parts as well. Furniture that has plastic or metal framework has to have threaded ends to make a tight and sturdy frame. Nuts and bolts have to be properly threaded and secure to the wall, other wood or metal pieces without breaking.
In the construction industry, pulleys, pins and bushings have to be made according to exact specifications. Industrial buildings, home construction and even road construction all have a need for CNC turned parts. A structure cannot be built safely if the hardware is made in a shoddy fashion.
General Hardware Needs
General hardware such as spacers, nuts, bolts and washers are all pieces that are made from programmed CNC machines. The variety of lengths, widths and threading sizes used for dozens of products means that the CNC machinist has to pay attention to the dimensions programmed into the machine. A single millimetre off throws off the entire batch and makes them unusable for the application the items are required for.
As you can see, the major industries that use CNC turned parts require that each piece is created in a precise and exact manner. There are no almosts or close enoughs in this industry. Remoulding plastics costs companies more money in labour costs, as does any other material. In most cases, machinists have one chance to get the pieces created properly. Double checking measurements, depths, thread gaps and other vital information before starting the machine to run the batch is of the utmost importance. Successful CNC machinists know the machines inside and out. They area also aware of how to troubleshoot issues during production if a piece seems to be off even just slightly.
