1913.4 Automatic OperationItems in parentheses refer to Control Panel onpage 23.The Band Saw can store up to ten automatedprograms.1. Connect machine to power source.2. Select AUTO mode (J).3. Press Hydraulic Pump Start button (E).4. Feed the workpiece into the machine. It will beclamped automatically.5. Key in all necessary controller parameters(see under “Screen Functions”).6. Adjust blade guide post.7. Set blade speed (V).8. Set downfeed pressure (U).9. Press Operation Start (F).10. Start coolant flow (H). Indicator will light. Also,the conveyor screw will begin turning.11. The saw bow will descend quickly, then slowto the pre-programmed speed.12. Blade will stop at the lower limit. Bow will riseand work piece will be fed into position for nextcut.13. Saw will continue cycling until all commandshave been satisfied, then the motor will shutoff.13.5 Bundle CuttingRefer to Figure 30.The hydraulically-operated bundle clamps providedownward pressure on the workpiece, allowing thebundling of multiple, small diameter workpieces.1. Install the bundle clamps to the vises, asshown. The short side of the clamp shouldface the motor end of the saw. The clamp withthe hose pointing toward the motor (A) shouldbe placed on the stationary vise. The clampwith the hose pointing away from the motor (B)should be installed on the shuttle vise.2. Tighten the four knurled head pins (C) so thatthey just touch the bed; do not overtighten orthe vise will not move freely.3. Connect hydraulic hoses from the bundleclamps to the fixtures (D and E).4. Operations are the same as in the instructionsabove for either auto or manual mode.5. The buttons that operate the shuttle vise (Pand R, page 23) also control the bundleclamps. Thus, opening the shuttle vise willopen the bundle clamps; closing the shuttlevise will close the bundle clamps.Figure 3013.6 Evaluating Cutting EfficiencyIs the blade cutting efficiently? The best way todetermine this is to observe the chips formed bythe cutting blade.If the chip formation is powdery, then the feed rateis much too light, or the blade is dull.If the chips formed are curled, but colored — thatis, either blue or straw-colored from heat generatedduring the cut — then the feed rate is too high.13.7 Verifying Cutting AccuracyTest cuts can be used to determine whether or notyou have adjusted the blade accurately. Use 2-inch round bar stock to perform these test cuts, asfollows:1. With the bar stock securely clamped in thevise, make a cut through the bar stock (seeFigure 31).2. Mark the top of the bar stock.3. Move the bar stock about 1/4-inch past theblade so you can begin a second cut.4. Rotate the bar stock 180 degrees so that themark you made is now at the bottom of the cut.5. Make a cut through the bar stock.6. Measure the variation of the disk you have cutfrom the bar stock. Measure at the top andbottom of the disk.7. The saw blade can be considered correctlyadjusted when the variation measures no morethan 0.012 inch across the face of the disk.
