Blade Care & Break-In
Blade Care
To prolong blade life, always use a blade with the proper width, set, type, and pitch for each application. Maintain the appropriate feed rate, feed pressure, and blade speed and pay attention to the chip characteristics (Refer to the Chip Inspection Chart on Page 26). Keep your blades clean, since dirty or gummed up blades pass through the cutting material with much more resistance than clean blades, causing unnecessary heat.
Blade Break-In
The tips and edges of a new blade are extremely sharp. Cutting at too fast of a feed rate or too slow of a blade speed can fracture these tips and edges, quickly dulling the blade. Properly
Use the Chip Inspection Chart on Page 26 as a guide to evaluate the chips and ensure that the optimal blade speed and feed rate are being used.
To properly break-in a new blade:
1.Choose the correct speed for the blade and material of the operation.
2.Reduce the feed pressure by half for the first
3.To avoid twisting the blade when cutting, adjust the feed pressure when the total width of the blade is in the cut.
Downfeed Rate
Start and stop downfeed with the downfeed knob. The downfeed rate is adjusted by turning the downfeed rate adjust knob (Figure 24). Turning the knob clockwise decreases the downfeed rate and turning the knob counterclockwise increases the downfeed rate.

Downfeed Pressure
The downfeed pressure is controlled by the spring shown in Figure 25.
To decrease downfeed pressure, turn the cap screw clockwise to increase spring tension.
To increase downfeed pressure, turn the cap screw counterclockwise to release spring tension.
