CNC refers to computer numerical controlled machining. This allows complete automated part grinding to be performed almost entirely automatically. Even with the toughest of part shapes, like crankshaft assemblies, camshafts, bearings, valves or transmission shaft assemblies, it’s now common today to accomplish fast, reliable and even automatic full-scale machining using CNC machines. The advancement of computer numerical controlled (CNC) technology has opened new doors in the realm of metal fabrication. CNC can cut out anything from metal, plastic or other solid objects, leaving behind a much smoother and more evenly finished product than what could have been accomplished manually.
The first step is to determine the workpiece. If you’re working on an acrylic piece, then you can use a CNC grinding machine to grind down the rough top layer to produce a smooth and uniform piece. CNC may also be used to grind away all the way through a thin brass or copper wire, to produce a smooth edge. The same effect can be achieved by passing a drill press head through a workpiece and into the metal at the other end.
The next step is to set up the CNC grinding machines. You need a workpiece to be mounted on a spindle and the Maser type CNC grinding machines provide this, along with a range of tools that are all at the touch of a button. You can also program your machines to work on a particular material or geometry. These types of CNC grinding machines are referred to as “GMC” machines and can run on either Minicom or MMC cartridges.
Some types of CNC grinding machines have a fixed function, in which case they will come with the appropriate tools and all the necessary parts. These types of machines may also come equipped with a coolant lubricant supply, which allows them to operate even when their engine is not running. If you want your CNC grinding machines to function whilst your engine is running, then you will need to supply your equipment with a continuous coolant lubricant supply. Some of the machines that come with a coolant lubricant supply will also require that you regularly replace their coolant, to ensure that they function correctly.
Some CNC grinding machines also come equipped with a robotic arm. These are known as “arm swing” CNC grinding machines, and are particularly suitable for producing a variety of intricate, decorative facets. When these CNC grinding machines are used, it’s important to use fine grit stones in order to prevent any “micro-cracks” in the surface of the workpiece. As well as providing a high level of precision, a robotic arm can also make engraving more intricate and can make a much larger and broader workpiece. Because of this, CNC grinding machines with an arm are very useful for producing a range of complex facets.
Some people worry that they can’t use their CNC grinding machine for things such as engraving if they don’t have any human help. Although this isn’t necessarily true – the fully automatic and fully digital control systems that come with most machines can in fact provide the level of precision that humans can achieve, simply because they rely on the human brain to provide them with the relevant information. These human brain based systems have been developed by specialists in industries such as medicine and finance. Because they rely on the human brain for input, they are extremely accurate and, as we’ve found with CNC machinery, completely safe. However, it’s still worth remembering that fully automatic and fully digital CNC machinery do still need human intervention to operate, so even though you might have a fully automated machine, there may still be parts of the job that requires a bit of help.
