CNC Accesories : An Inside Look at CNC

If you talk to the common man on the street, they may know very little about CNC, CNC accesories, and how we need them for every day life. Little do they know that the CNC process will have already touched their life in one way or another. If you work in manufacturing then you will have heard of the term CNC and you’ll most likely have dealt with CNC machines and CNC accesoires at some point. Everything that an operator can do with conventional machine tools is programmable with a modern CNC machine. Next we take a closer look at CNC machines and their operations. Comuter Numerical Control is the future for all businesses, and traditonal manual machines are being seen less and less.

CNC AccesoriesCNC Accesories : Accuracy and Efficiency

CNC is the best way to make precision parts. It can do so effectively, and efficiently, and with the greatest levels of accuract. A CNC machine is  easy to keep up and running upon initial setup and requires only some preventative maintenance that you can often carry out yourself . Even the work piece loading process is automated in the most modern CNC shops with CNC accesories allowing for virtually no human presence on the factory floor.CNC operators are required to complete other tasks related to the operations of the CNC and these can include the maintenance of machines. Other tasks will include measuring work pieces and making necessary adjustments to keep the machine running always at maximum efficiency.

If a CNC could only move a work piece in two axes  functionality would be severely limited. This is why almost all modern CNC machines are programmed to operate in several other ways. The days of 2 axis machining are virtually obsolete, and modern machines now commonly work on 5 or more axes. The actual machine type also has to do with its programmable accessories as well. Some of these accessories would include the following. An automatic tool changer that allows the tool to be automatically placed in the spindle when machining and therefore making production time quicker as a machinist is not required for the changing of tools. The speed of the spindle can easily be specified from a remote computer and the spindle can be turned in two directions. In addition many machining operations must have coolant for lubrication and the levels of such should be checked frequently.

Large Operations

With CNC touching so many aspects of manufacturing and larger factory fabrication, almost all machining processes now incorporate the use of CNC. If we take a look at how CNC machining affects the world of metal removal and metal fabrication, we will see just how important CNC is. All the processes of facing, boring, turning, grooving, knurling, and threading that are involved in metal production are done with CNC turning centres. There are many variaties of these machines which include, CNC milling machines, CNC drilling and tapping centers, and CNC lathes. 

When using CNC in association to metal fabrication, let’s take an example think of a metal filing cabinet. All of the initial components are made of steel sheets of metal. These sheets are sheared to a certain size, and after this holes are placed in specific locations. The sheets are then formed to their final shapes by CNC machines.CNC machines are allso used for laser cutting, friction and ultrasonic welding, plasma cutting,  fabric cutting, routing and even sawing.
