Default Noisy Router

Anyone have any suggestions on a quiet or less noisy router. The Bosch router I have for my Shark CNC is extremely loud when turned on. It is loud before it even starts cutting. I have to leave the room because it is so loud. Would appreciate any and all suggestions. Thanks.

Routers tend to get loud when the bearings go bad. The brushes could also be going bad. The life of a router in a cnc application is far shorter than for bench top use because it is running so much more. Sounds to me like it's time to replace the router and plan on trying to rebuild the loud one so you have a spare for future needs.

You didn't say if you wear earphones or not. Should always wear hearing protection when using a router.

Router is brand new. Therefore, I don't think I would have to worry about bad bearings.

I had a Dewalt 618 and had to go outside or put the headphones on. Now I'm running a 2.2kw water cooled spindle and I can sit in the shop and talk on the phone while it's working away. Worth every penny!! But if you don't want to go that route then I've seen people build some really nice enclosures. Good luck and take care of your ears!!!!!! 🙂

Ceramic bearings would probably be quieter and would last longer too.

Are you running the router at the top speed setting or are you running at a lower setting to optimize feed rates and spindle speeds? The CNC Sharks have limited feed rates so you are probably running the router too fast. Running your router at a speed too high for your feed rates will cause the bit to get hot and dull quicker. Using the proper feed and speed for the bit allows the bit to cut chips that carry away the heat so the bit stays cooler. Running the spindle too fast produces dust and will spin the bit against the wood (rubbing) that produces a lot of heat. Running the router at the slower speed will also help to protect the router bearings from heat and prolong the life of your router. You don't say what model you are using, I'm guessing it is a Bosch 1617evs.

That is what I am using on my Shark HD1 and I am running mine on setting 3 which is around 16500. It runs a lot quieter at this lower speed and also makes it easy to get proper feeds and speeds for your bits. It is still noisier than a spindle would be.

Here is a speed chart for the setting on the Bosch 1617evs

Could you possibly provide a link as to where you bought your 2.2kw water-cooled spindle and what it cost?

Thank you.

Look at air cooled too!!!

You can get one from CNCRP that's made for your machine. Automation Technologies (?) out of the Chicago area is probably your best best otherwise.

FYI -- I have an air cooled spindle and VFD with about 10 minutes use on it. Will sell it cheaper than you can buy one. PM me if interested.

Now I know why old guys wear suspenders.

Mine was $315 from Ebay. About another $50 for water pump, hoses, flow indicator.
Amazing customer service, they sent an extra spindle when I complained about a noise.

CNCROUTERPARTS has a nice air cooled 2.2kw for $1,695. Great customer service too.
