A bedknife is approximately 2.5” wide x 22” long x .134” thick. One side of the length of the bedknife is a plurality of holes used to mount to the mower. The opposing side has a precision ground “lip” which is the cutting edge of the knife.
One step of the manufacturing process is to heat treat the bedknives to harden the steel for added wear. During this process of through hardening in high temperatures, the bedknives will warp or crown up to 0.75” over the length of the part.
This project is to create a machine to re-straighten the bedknives
1. The bedknives must be straight to within .005”.
2. The warp of the blade will not always be in the center
3. The material is hardened to 45-48 HRC.
4. The sharpened “lip” or edge cannot be touched in the process. Pushing on the lip will cause a kink or wave and render the knife unusable.
5. Straightening pressure can only be applied on the mounting side.
