noise level of 3600 RPM motor with gear head

[Runner4404spd]

does anyone have a 3600 RPM motor mounted to their IH or other gear head mill? i'm just curious as to how much louder it is. the gear head seems pretty loud as it is with the stock motor, i expect a little increase for the higher speeds but will it be unbearable?

I never ran the stock motor so I cant compare.
But I dont find the noise it generates to be bad. I should run it at half speed and then full speed.

FWIW: My gearhead on the mill is also pretty loud (compared to the gearhead lathe right next to it). I pulled the motor off recently hoping that the noise was the motor. Unfortunately, the motor spins very quietly and the noise is in the gearhead. I have the IH mill from a year ago. Mobil DTE Heavy Medium (ISO 68) is currently in the head but that may be switched to DTE Light in the near future as there currently is a lot of foaming.

Has anybody here removed the gears in the head and gone with a belt drive with a VFD controlling the motor????

I believe Arron converted one to beltdrive and also to cat30. It was up on the website for awile.

I dont know much about it . It was up on the website as the light Industrial version. He does have an upgraded servo system he calles that but he use to have up the converted spindle.

Runner - I replaced the stock motor with a faster 3600 rpm this evening and found the mill to have a much more tolerable sound if not actually quieter. It is now more of a high pitch were instead of a low pitch clanking of gears.

I am glad to hear that. I never ran the stock motor so I had nothing to compare to but the new motor was never an assualt on my ears.
Which motor did you go with?

Randall - I got the same motor that Aaron recommends on his web site. It is a metric Leeson 192074 from Motor Warehouse. They cut the shaft down for an extra $100 and it arrived two or three days after I ordered it. The VFD is a 3HP Hitachi SJ200 from Automation4Less.

Same as I did then. I like the vfd run motor alot more options for cnc control.
