VISE LOADING
The position in which material is placed in the vise can have a significant impact on the cost per cut.
Often, loading smaller bundles can mean greater sawing efficiency.
When it comes to cutting odd-shaped material, such as angles, I-beams, channel,
and tubing, the main point is to arrange the materials in such a way
that the blade cuts through as uniform a width as possible throughout the entire
distance of cut.
The following diagrams suggest some costeffective ways of loading and fixturing. Be sure, regardless of the
arrangement selected, that the work can be firmly secured to avoid damage to the machine or injury to the
operator.
BladeBreak -In
Completing a proper break-in on a new band saw blade will dramatically increase its life.
1. Select the proper band speed for the material to be cut.
2. Reduce the feed force/rate to achieve a cutting rate 20% to 50% of
normal (soft materials require a larger feed rate reduction than harder
materials).
3.Begin the first cut at the reduced rate. Make sure the teeth are forming a chip. Small adjustments to the band
speed may be made in the event of excessive noise/vibration. During the first cut, increase feed rate/force
slightly once the blade fully enters the workpiece.With each following cut, gradually increase feed rate/force until
normal cutting rate is reached.
