Computer Numerical Control (CNC) machines aid in manipulating other tools by using computer-aided software. These electro-mechanical devices are useful for cutting in three-dimensions when generating prototypes.
These machines run Computer-Aided Design (CAD) programs, which also help manage grinders, lathes, routers, and mills. Before buying the CNC machine, you need to understand the specifications and the nature of their work.
There considerations that you are supposed to make before buying or investing in this machine. Here are some tips to help you out in choosing the best CNC machinery.
The functionality of the CNC machine depends on several external factors and its ability to work within them. The device’s tolerance is known to affect the nature and type of deviations that it will experience.
External factors such as humidity and temperature affect the machine causing different levels of deviation on the device. If the variations rise too high, it may result in unusable pieces.
Machine tolerance, in this regard, refers to the ability of the CNC machine to withstand and resist the effects of the external factors.
Different CNC machines come at different prices. This variation in pricing is due to the various features of each device and model. The horizontal machining center (HMC) is more costly than the vertical machining center (VMC).
The cost of the vertical machining center makes it more appealing and affordable to small and medium-sized companies. An essential factor that you need to consider when working on the cost is the various expenses. The overall cost should consider the initial and operating costs of obtaining the CNC machine.
The productivity of the CNC machine is measured based on machine speed, which is an essential feature. The demands of the project your company is currently undertaking will dictate the pace required to complete it on time.
The vertical machining center is much faster than the horizontal machining center, making it much more productive in accomplishing tasks. The HMC’s design allows it to use the 4th axis about 85% of the production time while the VMC uses its 4th axis, only 25% of the production time.
The HMC is three times faster than the VMC. This factor, therefore, means that it increases production, reduces the labor costs, and increases the profit margins compared to the VMC.
The CNC machine requires electricity to function. The machines’ electric demands and consumption may differ, which may necessitate an increase in the workshop’s electricity supply. You must check the power requirements and specifications of the machine before making a purchase.
The advantage of the CNC machines is that the manufacturers design them with varying voltages; hence you can purchase one that fits the power supply you have.
The CNC machines make use of programming to function. Therefore, you may need to find out if you have the necessary skill set to operate the machine.
If none of the employees have ever used the CNC machine before, it will be necessary or them to undergo training first. If none of the employees can run the CNC machine and no training is available, you shouldn’t make the purchase yet.
When purchasing the CNC machine, you should always have the project requirements in mind. What are your present and future needs with regards to production? This machine comes in various forms and varieties; hence you should be specific about your requirements.
Since the different types of CNC machines come with various features, you must conduct a needs assessment before purchasing it. The machines’ features determine the nature of projects they can work on effectively, their speed, and the exact materials you can work with for production.
Neglecting this factor may lead to spending money on a machine that is not right for the job.
Some other important factors that you may need to consider when purchasing the CNC machine include the size of the device, the motor’s power, the after-sales services, and the cooling system.
