RE: Tersa Blades-- Re-sharpening11/25
We have a Laguna P24 planer (24-inch) which uses 430 mm HSS Tersa Blades (which are double-edged blades).
We would like to re-sharpen these blades. Does Tersa, the company, provide re-sharpening services for their blades?
Or, which professional companies in the US provide high-end re-sharpening services, where we could send out our blades to?
Also, what are the typical costs involved for re-sharpening?
Thanks for your help.
It is not practical to resharpen Tersa knies for a planer. The effective head diameter would change which would affect the infeed/outfeed rollers and chip breakers setup.
Unimerco in Saline, MI sharpens CARBIDE tersa blades (only). they will not sharpen HSS. the carbide's are quite expensive, and therefore worth sharpening. i have had many sets sharpened, with great results.
Tom is correct about the chipbreaker, holdowns and rollers are all calibrated to work at the diameter of the Tersa head. Change the diameter, and then you have to change all the settings downstream.
I would imagine that sharpening the carbide removes material in the 10/1000ths or even 100/1000ths. This would appear to have little or no effect on the operation of the planer. I imagine they will not sharpen more than once or twice.
I run Tersa in the S4S, jointer and planer.
If you search Utube there is a video of a jig to sharpen HSS Tersa. No idea if it worthwhile or cost effective.
