3 Tips to Choose the Right CNC Machine Tool


CNC (Computer Numerical Control) Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Some of the tools that can be controlled with CNC are lathes, mills, routers, and grinders. This technique is typically used in industries that are involved in the manufacturing of metal and plastic parts. It is used for producing complex shapes, especially 3-D shapes that require a high level of precision which cannot be achieved otherwise through manual machining. In addition, this process is great for repetitive tasks where a specific task has to be done in exactly the same manner over and over again.

So, whether you are undertaking a one-time project or planning for repetitive mass production, using a CNC machine tool can help you in getting tremendous output results by cutting down on the percentage of waste material. But with a wide range of types and manufacturers in the market, how to shop the right type of tool that suits your needs the best? Have a look at some of the important factors to help you choose the perfect option –

Material Type

CNC machines are capable of working on a variety of materials aluminum, copper, steel, titanium, etc. Every CNC machine is uniquely designed and the type of machine that is required to be bought has a lot to with the type of material it has to deal with. Plastic, Acrylic, and Aluminum are few materials that a CNC router can handle whereas cutting parts for automotive, defense, aerospace or medical industries may call for advanced CNC machines. Choosing the wrong machine tool can damage the material you want to process and at worst, the machine tool itself.

Scope of Work

After considering the material that needs to be cut, comes the job size. A larger cutting area would require a comparatively larger machine and would be more expensive. So, it is highly crucial to decide on the job size you are looking forward to manufacturing, not just at the present moment but also try to plan ahead and decide on the level of operation you will be undertaking in future. You obviously don’t want to have repeated costs breaking your bank whilst planning to expand your operations at a later stage. It is a one-time investment, so invest wisely.

Quantity VS Quality

Generally, every CNC machine is designed to give excellent precision and high-level outputs. But few projects need to be completed within tight deadlines and the smoothness of cuts are not really required for them; in such a case you can buy a machine that offers you straight and speedy cuts and helps you in mass production. However, if you are involved in a project that demands intricate designs, then the goal shifts from quantity to quality and you need to invest in a machine with more flutes on a CNC bit.

Last, but not the least, it is important to consider the storage capacity in your manufacturing area to make space for the newly bought machine tool. The area obviously varies from industry to industry, but before you bring in the machine, you have to make sure it has ample space for an efficient working.
