Computer Numerical Control (CNC) machining is a common technique that is contemporarily utilized in the metalworking industry. As opposed to conventional machines, CNC machining makes use of computerized systems which facilitate superior output in complicated shapes for a range of materials. A renowned example is the CNC milling machine.
Why CNC machining stands out:
Previous machines which were known as numerical control machines (NC) located their positions via G-codes. These G-codes were manipulated manually by the user unlike in CNC machining whereby this task is computerized.
In the most recent versions known as the parametric program, logical commands have been fixed in a manner that they can work together with these G-codes. This modified version allows users to regulate and manipulate system parameters effortlessly.
Benefits of using CNC machines:
The improvement in technology used in the manufacturing of these machines brought about a number of benefits. These include the following:
- There is improved speed, accuracy, productivity and efficiency of tasks
- They significantly reduce the incidents of accidents since computerized systems minimize the contact between the tools and the user. This makes the metalworking process a more comfortable undertaking.
CNC Milling Machines:
CNC milling machines function by using a computerized system to transmit signals to a stepper motor controller. This system instructs the stepper motor on the direction to follow and the number of steps it is supposed to take. The motor is linked to the drive mechanism of the mill in the X, Y and Z axes. Some CNC milling machines are known to utilize a servo motor as a replacement for the stepper motor, this has the below advantages:
- Metals can be cut at higher rates
- Servo motors have a feedback loop which enables the machine to accurately resume to its initial position.
How to find the best CNC milling machines:
These machines have become essential in very many facets of life especially in the running of our businesses. The purchasing of this machines entail that you have to find the right kind of supplier or dealer. The following are tips to assist you in identifying the most ideal place where the machines can be obtained from:
- Check the quality of the milling machine. Visit online forums to get information on the available brands in the market and the most reliable brands according to customer reviews.
- Choose a supplier or dealer with professional staff and highly skilled personnel to repair your milling machine if it breaks down
- If you are looking for a cost cutting option, some suppliers deal with second hand milling machines so, pursue such options.
Maintaining your CNC milling machine:
Once you have your milling machine purchased, some important tips can be followed to keep it in top condition. These machines are usually maintained by a set up process.
This includes the below procedures:
- Wipe the table to the T-holder to keep it free it from fragments and rust.
- Place its vise down and tighten it with bolts. Straighten the vices using an indicator
- Place every tool into collects and ensure they are safely locked.
- Set the collets into the changer of the tool as per to the manual of the machine.
- Confirm if the machine "knows" where it ought to stop. This is to guarantee that the machine makes an accurate cut.
- Set the spindle on the zero point then ignite the machine again on the X and Y axes
- Next, locate the Z point by lowering the spindle to the top of material. This point will be used as a reference in cutting other materials.
