I don't know a thing about CNCs, but our shop is getting one and I will probably never touch it. This machine has two gigantic vacuum pumps, I guess to hold the wood down. Do these pumps (in general) put off any heat when they run? Our shop gets crappy hot in the summer. The person that claims to know about them says no. Additionally (in general), do on-board computers need to be kept cool to operate, or can they take the heat? 100 degrees or just a bit better plus high humidity.
From contributor D:
The exhaust from my vac pump can reach 180 degrees, so yes, they do produce heat. I vent mine outside during the summer. My control cabinet has its own AC unit so the computer hardware stays cool. Computers love cool air.
We have had one Bendix pump needing a rebuild after about three years. Now I keep them well greased, cleaned, and turn them off every chance I get (they used to just run all day when the machines were powered up in the morning).
If you look at these machines with common sense like any other tool in the shop, instead of the typical fear and dealer-on-speed-dial attitude I've seen in many places, they can be extremely helpful, not just in productivity, but in expanding your horizons and thought processes. I embraced CNC from the start and encourage you to as well. In the early days there were some extremely fast and accurate Vietnamese bandsawyers in our shop that snickered when they could beat me making casing on the CNC. Now I can begin cutting perfect parts almost before they walk across the shop to the bandsaws.
