The right solution for cutting Nitinol (super hard metal)/ Hard Steel core(bar)

The right solution for cutting Nitinol (super hard metal)/ Hard Steel core(bar)

The right solution for cutting Nitinol (super hard metal)/ Hard Steel core(bar)

(OP)
Looking for a solution for cutting (super hard) Nitinol tubes and hard Steel cores(about 0.25" to 1"). Can "cold cutting saw" potentially be a solution? Im specifically asking about this method since I could avoid considering an exhaust system.

I would appreciate if you can share your comment with me.

Thanks,

Contact a saw supplier. You will need to use a coolant, usually these are water with a water soluble oil in them.
It may require a carbide tipped blade, and great care.

Thank you for the responses, so you still think a chop saw with cold saw wheel can work?

RE: The right solution for cutting Nitinol (super hard metal)/ Hard Steel core(bar)

Absolutely not. Cold cut saws are unique and expensive in that they have gearing to slow the blade down. Chop saws tend run directly at motor speed.

I live confused... are You cutting/machining...

Nitinol => nickel- titanium alloy [tube] material [that is bio-compatible]??

… AND also [separate-subject/material]...

UHS alloy steel [like bars, plate, etc]???

Listen to Tug, cold saws are special, very rigid, precise speeds, and controlled feeds. They are nothing like a chop saw.
Each material (and with tubing each wall thickness) will have its own blade/speed combination.
Cold saws are not fast, they are clean and precise. And expensive even before you start buying blades.
A good auto feed wet abrasive saw is a real option. They come with full hoods and take minimal ventilation.
Don't expect to get good cuts on difficult materials with a cheap solution, it doesn't work that way.

@WKTaylor its a M2 Steel as a mandrel for drawing
