CNC machinists spend a great deal of time learning how important it is to get parts made to exact specifications without making a mistake. Learning how the machines work and where to input the information to create CNC turned items also takes time. It is a precision career that requires patience, attention to detail and a meticulous personality.
CNC turned means that pieces of metal, plastic, PVC and types of alloys are put through a machine for threading, boring or sizing. The machines are programmed specifically to create specific grooves, holes, notches, lengths and widths of parts used for literally millions of applications from plumbing and automotive needs to construction needs.
Individual Hardware Pieces
Hundreds of individual hardware pieces are created with a CNC turned process per hours in factories. Each piece has to be looked over to ensure that it meets quality control standards. Nails, screws, nuts, bolts, spacers and washers are just a few of the individual hardware pieces that are created from this process.
A finishing process smooths edges by removing remnants of plastic or metal from the outer sections of items. This process also helps to shine the pieces and clean the grooves needed to secure the piece of hardware into the connecting item.
The variety of threaded and bored parts that are created from a CNC turned process require that the machines are well-maintained, properly cleaned and that diagnostics are run on them frequently. Most machines are designed to alert the machinist if any part of the process is off. The machinist is also notified if a vital part of the machine is malfunctioning and the manufacturing process needs to stop in order to repair the issue.
Threading and boring parts also require precision. Bored holes have to be a specific width and depth. With pieces popping into place, the bored piece has to fit snuggly without too much force. Grease and adhesives are also often added to bored holes to secure parts into place. Where threading is concerned, drill bits, screws and bolts require a specific pattern. In some applications, the thread patterns are wider apart than others and the grooves have to be a little deeper. Being able to run quality control checks by sight and not individual measurements is a difficult task and takes years of training.
As you can see, there are a lot of steps to make CNC turned items. With literally thousands of types of pieces being made from these machines, some companies opt to specialise in specific pieces or parts rather than running a general CNC turning factory. This causes confusion and often overwhelms the manufacturing process. It leads to projects having to be rushed and mistakes being made. Busy companies do not have time to put an order back through for mistakes to be corrected as it throws off general production completely. These manufacturing facilities work as a well-oiled machine with specific processes, specific procedures for employee safety and an absolute project schedule with no room for mistakes or machinery breakdowns.
