Thread: Thicknesser and embedded screw didn't play well together

Thanks Phil

I'm glad I put it out there; could have made a mistake.
Learning as we go stuff.

I appreciate your input and thoughts in this thread.

Cheers
Keith

Need the 6"/150mm radius

The red line is a 150mm radius line
The insert on the left is one of my damaged ones and i'm reminded that I need to ask for the r0.5mm radius on the corners as well
The insert on the right is one of the 30 degree units and you can see the larger base area that would stop it seating correctly

besides the different sizes the variation just in the 15mm versions for the edge is straight, R50, R100, R150 add in sharp or R0.5 corners. The company i was speaking to also made the bevel angles in 30, 35, and 40. 37 was a new grind for them and they would need to configure the CNC hence the MOQ

Then add in carbide grades and we are in a minefield

Oh the joy of being a pioneer! First to destroy cutters .

Any progress on sourcing replacement cutters?

CTS cutterheads take 15 x 15 x 2.5 r150 inserts, these ones - CTS Shelix Cutterhead Carbide Inserts
Are these the correct fitment?

Gday aldav,

Thanks for link.
The Sherwood 15 x 15 x 2.5 r150 inserts are 37 degree side angle.
I couldn't see a side angle listed.
Obvious - contact SJE.
Still a WIP, but maybe getting there.

No they're not the right ones as the CTS is only 30°. I have both these cutter heads and I have checked them against each other and the CTS inserts don't fit.

Are these suitable?

In everyway except they're look square edged. (Darn)


BUT, thank you for looking and the link.
Still a W.I.P.

They are so close but they are missing the R150 radius on the cutting edge. Not sure how critical that is in making them seat properly in the head. Certainly getting closer.

I've got to say that Timbecon have managed to effectively lock us into buying the replacement cutters direct as the R150 is in most cases the deal breaker in finding a generic.
The nice thing is we get spares to start and unless you unlucky or dumb like me your not even likely to need the spares.

I am still working on sourcing custom manufactured units to spec just going far slower than i'd like but it is hibernating season here.

The 37 deg angle is critical for seating the cutters correctly. R150 is for them to provide a nice smooth finish, the straight blades would leave a small line I believe but very happy to be proved wrong on this.

Edit: the linked ones also do not have a corner radius making them more likely to chip the very corner ruining two edges at a time

cheers

These inserts come very close but unfortunately don't seem to combine the R150 and the 37° in the one item.
