Buying a CNC Machine Tool Guide
When looking to make an investment in a CNC machine tool, the decision should not be taken lightly. Not only is it a significant financial commitment, but you will need to decide which features are important for your needs, and which features can be sacrificed to work within your budget. A good starting point is to ask yourself what kind of components you plan to create and the associated tolerances you need to achieve.
Defining Your Requirements
The first step is to define the basic requirements for your CNC machine tool in terms of maximum size, feed rate, and range of motion. Do you need to be able to work with large work pieces or will smaller, more intricately shaped components be more suitable? Do you need to be able to achieve high feed rates or are more precise finishing results more important? By answering questions such as these, you will be able to narrow down the range of machine tool options available to you.
Choosing the Right Type of Machine Tool
Once you have determined the requirements of your application, you can start looking at specific machine tools and comparing the features offered by different manufacturers. Different types of machine tools are suited to different types of applications. For example, milling machines are suitable for creating components with flat or curved surfaces and for drilling, tapping and reaming holes. Lathes are typically used for creating round or symmetrical components, and complex surface contouring.
The range of functions you need and the accuracy of the results you are aiming for will be major factors when deciding which type of machine tool to choose. Ensure that whichever option you pick is compatible with the production volume you need to achieve and the type of components you will be producing.
Getting the Right Software
CNC machine tools are often accompanied by software that enables automation and precise control. Make sure to speak to manufacturers about their software packages, particularly if you have experience operating different programs. You will also need to ensure that whatever software you are provided with integrates into your existing systems and is free from any hardware or software compatibility issues.
Premium Quality Components
When investing in a CNC machine tool, you should think of it like you would a car; it is only as good as its components. Ensure that the components of the machine you are considering are of the highest quality by asking the manufacturer for information on their suppliers and the processes used when manufacturing each component. Items such as spindles, chuck and tool holders need to be proven to be durable and reliable, to ensure that runs are uninterrupted and productivity is not sacrificed.
Getting Service and Support
Eventually, all machines will require servicing and eventually, they will need to be replaced. If a component fails or needs to be replaced, you will want to be able to turn to a reputable services department to provide prompt and effective support. This means dealing with a manufacturer that has a well-established global presence and is known for excellent service and support.
Conclusion
The decision of which CNC machine tool to purchase should not be taken lightly. Define the requirements of your application, choose the right type of machine tool, take into consideration the accompanying software, ensure the components used are of premium quality and make sure you have access to a reliable source of service and support. Making the right choice will ensure productivity and accuracy for your manufacturing process.
