Choosing the Right CNC Vacuum
May 03, 2022
When choosing a CNC vacuum, some commonly asked questions pertain to vacuum strength, durability, and which type to use for different applications. At Republic Manufacturing, we can answer those questions and also point you in the right direction when choosing which CNC vacuum is right for you!
What determines which CNC vacuum is the best?
Several factors come into play when deciding which CNC vacuum hold-down is the best. Oil lubricated pumps have the highest vacuum level, while the technology of the rotary claw pumps and the dry vane pumps allows for an even level of vacuum and air flow. High vacuum pressure holds down the surfaces of products, so heavier products require higher vacuum levels. Random shape cutting causes a higher air flow, so the type of pump used must have a lower pressure pump. For example, wood and aluminum when cut allow for more air flow. For this type of job, a regenerative blower or Positive displacement pump would be efficient. Consider these when choosing a CNC vacuum:-
- Size of materials
- Cost
- Preferred maintenance (high or low)
- Table sizes
- Vacuum strength and air flow
