Page 7: Foundation Layout And Set-Up
3.2 Foundation layout and set-up : 3.2.1 Foundation : The foundation should be constructed of reinforced concrete and must be level and flat. After the proper leveling position has been obtained , anchor the machine with anchor bolts. The position of anchor bolts and floor dimensions are shown in fig 4: Fig. -
Page 8: Leveling
3.2.2 Leveling : The production accuracy of all precision machinery depends on the accuracy which the machine is installed . Manufacturing tolerance of the machine can only be guaranteed if the machine is firmly and properly installed . Once the machine is lowered on the prepared foundation . Machinist levels should be used alternately on the vice slide plates and the work feed table , and adjust the left-and-right and fore-and-aft level of the machine with leveling bolt . -

Page 16: Operating Preparation
4.3 OPERATING PREPARATION There are several steps will be taken before start the machine. (1) CHOOSE PROPER SAW BLADE : Select the saw blade best suited to the workpiece to be cut, Size and shape of the workpiece , and type of material should all be considered when selecting the saw blade to be used . - Page 17 (7) ADJUST THE FEED RATE : Select suitable feed rate for the workpiece to be cut. This varies according to the size and shape of the workpiece, type of material , and what type of saw blade is being used. As a guide hard materials, wide workpiece or structural sections and tubing have to be cut at a slower rate that mild steel bar.

5.2 Others VARIABLES WHICH AFFECT BANDSAW BLADE LIFE 1 . The Operator - The operator is the most important variable at any test. He can make or break any test and often has a great deal of influence over whose bandsaw blades are used. He can also be a good source of information on what is going on, competitive situations, relationships with manufacturers or distributors, etc. - Page 23 12. Machine Condition-Whether a machine is old or new, and whether well maintained or not contributes to how well it runs and how long the band last. The better shape a machine is in, the better the bands will run. Poor machines ruin bandsaw blades. 13.
