Modern manufacturing environments require the use of CNC machine tools, which are essential work tools. Increased production speeds, constantly changing parts with increased complexity, and a focus on consistent product quality necessitate the maintenance of CNC machines in order to meet or exceed these demands.
These suggestions will assist you in getting the most out of your CNC machines over an extended period of time.
Do your best to maintain a consistent temperature in the workshop because fluctuations and changes in temperature can affect tolerances. Make sure that your CNC machines are running on clean air. Your air compressor should not be too far away and should be able to provide clean, dry, filtered air at all times.
Air is used by CNC machining investment to clean the spindle and tool taper during tool change, to provide air for the Air-Oil lubrication system at the spindle (if available), to clear the tool measuring system, and to operate inside Linear Glass Scales (if available) to protect your expensive glass scale from external pollutants.(Constant positive air pressure from inside to outside), a similar system is used at the nose of your machine spindle to prevent coolant or dirt from entering the spindle during machining.
Reliability and accuracy
Make sure you understand the components that go into your CNC machines. Linear drive systems are certainly modern and attractive; however, they are also more sensitive and expensive than other drive systems. While they may be able to assist your machines in achieving a slightly better tolerance, they are best utilized in a more favorable machining environment.
In addition to ensuring that your CNC machines have a strong mechanical structure and high-quality components, you should pay close attention to the environment in which they will be operating. However, it is widely overlooked and ignored, despite its importance.
Constructing the environment
Setup time and changeovers will be reduced if you plan ahead and locate fixtures, tools, and materials near your CNC machines. If you are unable to do so beside or near your machines due to a lack of available space, you should designate a specific area within your facility for the preparation work. This will ensure that you have enough time to prepare and that you have everything you need to complete the job.
Check the coolant on a regular basis to ensure that the correct amount and mixture is being used to allow your machine to operate continuously.
Avoid using coolant with a high concentration because this can cause machine damage as well as rusting or corroding of components. Additionally, it has the potential to harm the health of your operator.
Different Cutting Instruments
To achieve a high-quality surface and finishing, make sure to use the proper cutting tools and start with the recommended cutting settings. If your operator has a lot of experience, he will know exactly what needs to be done in order to get the best results.
Use of blunt tools, incorrect (dimensioned) tools, or tools that are not appropriate for the materials being worked with can result in rough edges, cutter marks, raised marks, or burn marks on the finished surfaces. Alternatively, it could result in poor performance.
When machining parts, make sure to use the appropriate feeds and speeds. Take note that the following factors can have an impact on the surface quality of your part or mold:Vibration caused by the CNC machine itself; tooling that is not sharp or unbalanced; tool holders that are not suitable or unbalanced; as well as influence from external sources to your machine (mentioned in the previous point – dust or shock waves created by presses, stamping, or electrical variations and fluctuations). These factors will not only shorten the life of your tools, but they may also shorten the lifespan of your CNC machine's spindle.
