7.3. COOLANT SYSTEM The coolant system is composed of a Coolant Pump (45), a Tank (84), installed inside of Cabinet (53) of machine (figure 15). The Pump (45) captures the coolant liquid from Tank (84) and send it through of the hoses to the Distributor (46) (figure 05B). This way, through other hoses, coolant is sent to both Guides (27) and (30). The quantity of coolant liquid that leaves the guides can be regulated by means of Taps (figura 13A). The emulsion coolant (cutting oil) ensures the blade cooling, a good disposal of wastes and avoid oxidation of the cut material. The Coolant Pump (45) is switched on or off automatically with the operation or stopping of Motor (22) of the blade, if the Switch (18) is in ON position. The level coolant liquid can be controlled through of the Oil Gauge (64) installed of rear side and external of Cabinet (53), as observed in the figure 15. Inside of Tank (84) has a reservoir of sediments that should be clean with regularly, preferably at each 2 days in the continuous use.

BLADE LENGTH The blade length varies according to the band saw machine type and specifications. Please find the correct blade length on your band saw machine user manual.
PITCH Pitch is the number of teeth per inch or 25mm. Cutting thinner sections requires a finer pitch (more teeth per inch/25mm). Thick sections require coarser pitches (fewer teeth per inch/25mm). The charts are good guidelines. Because the cross section limits in the chart are broad and overlap, choose a coarser pitch if the speed of cut is most important. Choose a finer pitch if finish is most important. Section Size (Inch)

BASIC BLADE CHANGE GUIDELINES
56
REV.01 - JAN/12
S4240 - 220/380V - ING
BLADE BREAK-IN Using the right break-in procedures for a bimetal blade assures longer blade life, faster cuts for a longer period of time and consistent performance. Conversely, blade life can be significantly compromised if the proper break-in procedures are not followed.
LONGER BLADE LIFE
NEW BLADE WITH RAZOR SHARP TEETH
TOOTH CORRECTLY BROKEN IN
The teeth on a new band saw blade are razor sharp. To withstand the cutting pressures of band sawing, the tip of each tooth should be honed to create an extremely small radius on its tip. Easy-to-cut material such as carbon steel and aluminum: A. Run the normal surface feet per minute (SFPM). B. Adjust the feed pressure to about one-half the normal cutting rate for the first few cuts or for 50-100 square inches (323-645 sq.cm). C. Increase to the normal cutting rate. D. Avoid vibration. Hard-to-cut materials such as nickel-based alloys like inconel, hardened steels,tool steels and stainless steels: A. Run the normal surface feet per minute (SFPM). B. Adjust the feed pressure to about threequarters of the normal cutting rate for the first few cuts or for 25-75 square inches (161-484 sq.cm). C. Then increase the cutting rate part way to normal for the next few cuts. D. Then increase to the normal cutting rate. E. Avoid vibration.
START TO CUT MATERIAL AT REDUCED CUTTING RATE
BAND SAW SERVICE & SUPPORT Starrett service technicians are available to tune up and perform preventative maintenance on your production sawing machine using Starrett Band Saw Blades, at no additional cost. They fully review machine condition, blade mounting and operation in detail, making adjustments, as required, to help maintain good sawing and long life for both the machine and blades.
TRAINING
TOOTH INCORRECTLY BROKEN IN
AFTER BREAK-IN WHEN THE BLADE HAS FULLY ENTERED THE WORKPIECE, INCREASE THE FEED RATE OVER A SERIES OF CUTS UNTIL THE RECOMMENDED CUTTING RATE IS ACHIEVED
Starrett service technicians can also instruct saw operators on achieving the best performance of blade and machine for your applications. Contact your Starrett Band Saw distributor about arranging a visit to your workplace by a Starrett service technician.
