How to Use a Slitting Saw like a Pro: A Complete Beginner’s Guide

What exactly is a Slitting Saw?

A slitting saw could be just what you need if you've ever attempted to create small slots, grooves, or cuts in metal and found your tools to be insufficient.

A narrow, circular cutting blade called a slitting saw is used with a CNC or milling machine to precisely cut a variety of materials. Imagine it as a miniature circular saw blade that has been specially made for precise machining.

Slitting Saw vs End Mill: What’s the Difference?

You might be wondering, “Why not just use an end mill?”

Great question. Here’s the key difference:

Use a slitting saw when you need thin, clean cuts with high accuracy and minimal waste.

Common Uses for Slitting Saws

Slitting saws aren’t just for industrial shops. They’re used in:

·         Tool and die making

·         Slotting grooves or keyways

·         Cutting tubing and thin-walled stock

·         Jewellery and small parts manufacturing

·         PCB board slitting

If you're in metalworking, aerospace, or even watch repair, a slitting saw might be one of the most efficient tools in your shop.

How to Use a Slitting Saw (Step-by-Step)

A simple procedure for operating a slitting saw on a milling machine is as follows:

1.     Select the right blade

             Select the appropriate blade based on its diameter, thickness, and material. Choose cobalt or carbide for tougher metals.

2.     Install on the correct arbor

             The arbor's dimensions should match those of your machine's spindle and blade bores.

            3.   Tightly secure your workpiece.

             Make use of a sturdy setup because vibration destroys blades and accuracy.

4.     Configure your speeds and feeds

             Use a slower feed rate & RPM spindle. To extend the life of your tool, use cutting fluid.

5.     If necessary, make several passes

             A deep cut should not be made all at once, especially with thicker stock.

Tips for Slitting Saw Success

·         Keep an eye out for runout; even a small wobbles might spoil a cut.

·         Be careful while using plunge cutting; not all saws are suitable for it.

·         Take into account tooth geometry: Faster cuts result from fewer teeth, and finer finishes from more teeth.

·         Maintain the blade's lubrication and coolness.
