Slitting saws are different. Yeah, we’ve talked about it before. We covered slitting saw techniques in another blog you might want to review. Today we take a brief look at selecting a slitting saw arbor and then using the right feeds and speeds.
Slitting Saw Arbors
As important as picking the right saw blades is picking the right slitting saw arbors. Some home hobbyist websites recommend making a slitting saw arbor as an “easy-to-so” project. That’s just bad advice. If you can get a high-quality slitting saw arbor for $50 or under why would you waste time and material on an inferior arbor? Besides why waste your time on such a boring project?
With any cut, you don’t want your blade to wander. For slitting saw arbors, it is critical to absorb cutter vibration lest you destroy the blade, destroy the work piece, or worst case scenario: destroy the blade and the work piece.
Select the arbor that will get your blade close to the work area. Once you start cutting, dive in! By burying the cutter in the work early it will actually provide support to the blade. That doesn’t mean speeds are high. Overspeed is sure to kill. Speaking of which, let’s look at feeds and speeds.
Slitting Saw Speeds and Feeds
Your RPMs will depend on the saw material. RPMs are different from high speed steel than they are with carbide blades. The work material comes into the equation as well.
Cutting Speed/Saw Diameter x 4 = RPM
Once you have calculated the saw speed the next thing you need to figure is the feed.
Chipload per Tooth x No. of Teeth x No. of Teeth = Feed
The most accurate way to calculate your speeds and feeds is with software. FS Wizard is a free on-line calculator. The G-Wizard calculator is available for purchase at CNCCookbook.com. The advantage of purchased software is the ability to store tool information for use again.
