CNC stands for Computer Numerical Control and a CNC machine is a controller or a computer in which all the standard program of instructions is fed. CNC machining is used primarily in the manufacturing sector where computer systems are used to control various tools. The work is critical and delicate; therefore it is very important to choose the right CNC machine for the job.
Here are a few things which need to be ticked off the list while you are choosing the right CNC machine for your production unit.
The weight of the CNC machine is definitely to be considered when you are looking forward to buy one. These machines are available is iron cast, aluminum, and polymer composite. If you are looking for a powerful machine with promising stringency, you can go for the iron cast construction. That’s for units where the machine is not required to be moved about frequently. Aluminum and polyester are lighter options to consider.
When you are employing a CNC machine in your firm, you should choose the one that can cut the largest required area. For example, if you need to laser cut metals for your industry, the largest piece of metal that needs to be cut, should be equivalent or smaller to the range of the CNC machine.
The speed of a CNC machine is also referred as the feed rate or the axis feed rate. To choose the right CNC machine, you need to inquire how fast the machine can work while cutting supply.
Your workspace and the part of it you can allocate to your CNC machine is also one of the factors you need to keep in mind while you choose a CNC machine for your firm. If you have a large workshop, you can go for iron cast machines which are bulky but as effective and powerful.
While choosing a machine you should also see how easy (or difficult) it is to procure the spare parts for your machine. After some time, due to wear and tear, you would definitely need to replace parts of your machine. If you are purchasing popular machines like Amada or Trumpf, getting spare parts for your Trumpf machine, for example Trumpf laser parts is relatively easy. But it may not be so for machines of lesser known brands.
Not all work spaces has capacity in the terms of electrical power. Since these machines can be pretty powerful, you need to be sure about the power requirements of the machine.
Stepper or Servos?
The motor drive types of the CNC machines are known as stepper and servos. Servos are costlier than steppers but definitely are more promising and accurate. The strength of the servo system lies in its function that it checks the position of the measuring device at each move. If your final product doesn’t need to be pinpoint accurate, you can go for stepper as well.
Other Things To Consider
The above mentioned points are most vital factors you need to consider while choosing the right CNC machine. Apart from it, you should look into the following things:
- Spindle speed of the machine.
- Whether it uses industry standard codes.
- Whether it provides unlimited program lengths.
- The number of axis.
- Mechanical movement range.
