If someone has recently purchased their first machine, they are likely excited about starting their first project. From making parts of a clock or bicycle wheels to building a guitar, the options are vast. With the right CNC machine, it is possible to create almost anything.

 

All a person needs to do is put in time and effort and to purchase the right CNC machine. However, for those who are just starting out they may need a bit more help and guidance. If that is the case, keep reading. Here CNC machine users can learn more about the right way to use these machines and how to ensure the project is a success.

 

Purchase Quality Cutters

 

When it comes to CNC machining, a user is going to get what they pay for. This means they should avoid low-quality, cheap cutters. There is no need to spend too much on the top brand cutters, but it is a good idea to get quality cutters that come from a known brand that offers affordable prices. This is going to make a massive difference in the quality of the products that are created. It will also help to eliminate unnecessary issues that may occur if cheaper tools are purchased.

 

For example, buying carbide cutters is a smart move because they are going to last longer. It is also wise to choose a few various sizes, like a half of an inch and a fourth of an inch to name a few. Also, be sure always to wear safety goggles. Cutters used with CNC machines tend to break. It is also smart to purchase an assortment of drills.

 

Invest in a Quality Pair of Parallels, Clamping Kit, and Vise

 

Holding the parts being worked on steady and still is a must. It is imperative to invest in a quality vise that is going to last for several years. After all, serious issues may arise if the part shifts out of the proper position.

 

A quality clamping kit is going to mount the vise to the T-slots of the table. The last step is to get a good set of parallels that will keep the piece being worked on raised evenly for when the cutting spindle or tool passes over.

 

Prevent Chip Buildup with a Misting Set Up

 

CNC machine users can choose from two options for coolant systems, which include a micro drop or a siphon-based system. The siphon set up atomizes the coolant material into a type of aerosol. This is often messy. With a micro-drop system, the coolant is pressurized, which keeps the air and coolant in different chambers until they reach the tool's tip.

 

If the micro-drop system is selected, the coolant will vaporize when it hits the workplace. This process is more efficient and is not as messy. A quality misting system is also going to help prevent issues related to chip buildup, too.

 

Learn the Right Way to Use MDI

 

A person can save quite a bit of time, while increasing productivity by using MDI -; Manual Data Input. This is accessed using a MDI keypad that is found on the control panel on the CNC machine. It does not require much learning is going to help users save quite a bit of time.

 

It is possible to set a few basic g-codes and adjust the X, Y, and Z coordinates, move the axes, and the machine is going to move quickly after the information is inputted. This quick movement of the machine is called "rapids." The cutter must go where it is directed.

 

Use a Feeds and Speeds Calculator to Improve Accuracy

 

When making cuts with a CNC machine, accuracy is a top priority. To make sure this is done, it is important to use feeds and speeds calculator to ensure the spindle speeds and feed rate are precise from the first cut that is made.

 

CNC machining is entirely different from the manual machining process. It is necessary to make sure the feeds and the speeds are correct, right from the beginning. This is why using a feed and speeds calculator is so important.

 

Avoid Using Stainless Steel

 

When someone is ready to make cuts, they should make sure to avoid stainless steel at first. It is better to feel confident with the softer materials first and then master the cuts with these materials while reducing the possibility of causing premature wear to the cutters or even breaking them. The goal is to achieve nice finishes. There are quite a few options to choose from in the "mild steel" category.

 

Create a Few Sets of Step Jaws

 

Using the saw, cut a few pieces of material that are a little oversized. These will be vise jaws. Be sure to cut the stock slightly larger. The next step in the process is to square the blocks. When something is squared, it means a series of milling cuts are made until all the sides are perpendicular or parallel to one another, which makes the workpiece "square."

 

Once the material is squared, it will be cut to the proper size by continuing to mill it until it fits the vice jaws. It is necessary to have two square pieces, which is one for each of the jaws. The next step is to drill and to countersink the mounting holes. The last step is to mill a step on each jaw.

 

Learning the CNC Machining Process

 

When it comes to CNC machining, there are more than a few steps that need to be considered. Take the time to use the steps and tips here to ensure that the desired results are achieved. Being informed, knowing what to do and what to expect is the best way to get the desired results.

 

Take some time to learn the proper way to use the machine to achieve the best results with it. With time, practice, and effort, it is possible to ensure that the proper pieces are created and that the desired results are achieved.
