What You Need To Know About A CNC Machine Before You Buy

CNC Machine

Manufacturing has never been more efficient than with a compact CNC milling machine. The mills allow you to have a smooth process and standardized output. However, you must settle on the best mills for the best results and the machine’s longevity. This article will examine the five essential questions before getting a CNC machine.

How Big Is The Controller Touchscreen?

Computer Numerical Control (CNC) is a manufacturing process where a programmed computer directs the movement of machinery. A controller provides capabilities that range from straightforward linear controls to compound algorithms with multiple control axes. Getting a controller with a touchscreen that is big enough would be advisable. Small touchscreens will have significant limitations once you start functioning with numerous sentences. Therefore, aim to get a touchscreen that is not tiny, cheap, or below 8 inches. A fully configurable touchscreen allows the user to select the parameters to display on the data logger and the MultiCon controller. It also allows graphical formatting, including bar graphs, charts, numeric values, and dials. The operator will, therefore, need a large touchscreen to avoid errors. You will also easily select cuts and cabinets and make edits on the fly with a compact CNC milling machine above 20 inches. And there are many options to choose from in the market. Therefore, do not settle on a cheap CNC machine with a small screen controller.

Are The Setups And Changeovers Fast and Easy?

A long setup duration is a reality many manufacturers have to face. Worse, setting up as an activity does not add any value to the manufacturing. Therefore, every business should aspire to have a setup that is short as possible. A setup changeover is a time taken for a setup from the last excellent piece of a job to the first perfect piece of the next job. Activities at play include preparations, teardowns, loading tools, parts, fixtures, and machine programs. You will have to count all these factors as part of the setup to develop a consistent starting point where you can improve. There are many reasons you should go for a CNC machine with little setup time or try to reduce your setup time. The main reason is that you will ultimately increase productivity and profitability. A business with a quick changeover time will quickly achieve its goals and have higher customer satisfaction. A machine that allows you to quickly set up a new job will enable you to run different products on the same machine. The setup time can be internal or external. You can perform external setup times while the machine is running and the internal setup while the machine is stopped. Therefore, ensure the selected machine has both easy and fast internal and external changeover time.

Are Workpieces Properly Supported?

You need to understand CNC machine basics before trying to operate one. Knowing the different parts and their functionality is very crucial. By understanding the basics, you will know whether a workpiece is supported and how to load and hold it. One of the essential aspects of the CNC milling machine is loading and work holding. The workpiece will be as good as how steadily and well it stays on the machine’s work surface. Engineers have created different ways to ensure the workpiece is stable. The first step of milling is to insert a workpiece into your CNC machine’s holding device or work surface. You will follow this by placing the milling tools on the spindle. The directionality taken by the machine during the milling process can be vertical or horizontal, depending on CAD requirements. After securing the workplace, downloading the programming, and attaching the tool, you will activate the program for milling to start. Depending on the instructions, the workpiece is shifted, rotated, manipulated, and positioned for cutting. The cuts can be of different forms: tool movement across a stationary workpiece, slow feed into a stationery tool, or a combination of both. Typically, most CNC machines have a climb milling operation meaning the cutter and the workpiece move in the same direction.CNC machines have milling operations suitable for different products and industries with some milling processes, including face, plain, form, and angular milling. There is also specialized milling for different workpieces. Therefore, you should understand the milling process of a machine and whether it is in line with what you want to perform on your workpieces.

Is There An Installation Cost?

Many factors go into determining the final cost of your CNC machine. Unfortunately, the total cost will not be cheap regardless of what you do. But you can try to save some bucks by going for a machine that will not have high installation costs. Setup for simple parts is typically not complicated, and the shop minimums usually apply. Complex components may require multiple setups and several fixtures. The time and cost of installation might increase exponentially. Typically you will work with the manufacturer to complete the installation process until the machine works properly. Go through the options and try to settle on a manufacturer with low or no installation costs. 

How Long Does The Warranty Last? 

Different manufacturers have different warranties on their CNC machines. Additionally, manufacturers may offer a limited warranty and an option for an extended warranty that you will have to purchase. Companies will also bear other limits and exclusions. Always go for machines with more extended warranties. A longer warranty shows the manufacturer believes in the product. Therefore, it is highly likely the device is of high quality. And in the event the machine breaks down in the stipulated period or develops any fault, the company will come and repair it, getting it up and running.
