Before tightening the bed knives securely, determine that the knives are set properly by manually rotating the rotor in the reversed operating direction to ensure that no rotor knife touches the bed knives and that the proper gap has been established.
Recommended Rotor and Bed Knife Setting Assembly Knife Sharpening Knives may be sent to Security Engineered Machinery for sharpening or they may be sharpened by a capable machine shop in your area. When sharpening the rotor knives, they must be sharpened as a set to maintain the proper tolerance between the bed knives.
Notes on Knife Grinding After regrinding several times, the knives must be checked to be sure that there will still be adjustment left in the bed knives. The general rule is to place a rotor knife and bed knife back to back as shown in the diagram shown below, and then measure the total width (dimension “A”) of both knives.
