As Bob said, you get benefits from having two of whatever you depend on. If it's the spindle speed you care about, then you can probably experiment with removing the usual motor and spindle assembly (keep them as backups for the new one) and bolting on something else. The TAIG is nice that way.
Ever consider compressed air tools? I hear they can be surprisingly fast and powerful, and have inherent cooling.
Plus with two, you can use one as the coarse pass, and one as the fine pass, without the trouble of tool changing. |
