Improving Quality in CNC Machine Environments: Reducing Cutting Tool Vibration

Posted by Dror Pockard on Sep 20, 2015 3:09:13 PM

Quality is top of mind in every organization, but in the exacting world of CNC machining, it takes on a whole new meaning.  These companies must continuously eliminate any possible issues that could lead to work piece flaws. 


When it comes to ensuring quality in a CNC machine environment, one of the biggest factors a company needs to take into consideration is spindle vibration. 

Colibri-blog-tallSo how can a company eliminate vibrational issues from their CNC machine environments? Use a high speed machining (HSM) spindle that is dynamically balanced to comply with stringent ISO 1940/1 (balance quality requirements for rigid rotors) standards.  Dynamic balancing is an extra step that certain spindle manufacturers, like Colibri, take to ensure the quality of their products. HSM spindles that adhere to ISO 1940/1 standards are guaranteed to comply with the quality requirements.

There is an additional benefit to reducing vibration in CNC machine environments. When cutting tools are used under proper cutting conditions, the machining process is stable and the tool life is prolonged. This, of course, ensures more precision in the cutting process.   

From a workmanship perspective, a dynamically balanced HSM spindle is critical for ensuring top quality across the entire job.

Regardless of the cutting, any vibration created by a HSM spindle will degrade quality over the long run.  By choosing one that is dynamically balanced and compliant with ISO 1940/1 standards, the HSM spindle will ensure that you do not have returns because your work pieces do not meet customer specifications.
