Model SB1018 SAFETY For Machines Mfg. Since 8/09 SAFETY Understanding Risks of Machinery Operating all machinery and machining equipment can be dangerous or relatively safe depending on how it is installed and maintained, and the operator's experience, common sense, risk awareness, working conditions, and use of personal protective equipment (safety glasses, respirators, etc.). The owner of this machinery or equipment is ultimately responsible for its safe use.
For Machines Mfg. Since 8/09 SAFETY Model SB1018 5. Entanglement: Loose clothing, gloves, neckties, jewelry or long hair may get caught in moving parts, causing entanglement, amputation, crushing, or strangulation. Reduce this risk by removing/securing these items so they cannot contact moving parts. 11. Chuck Keys or Adjusting Tools: Tools used to adjust spindles, chucks, or any moving/ rotating parts will become dangerous projectiles if left in place when the machine is started.
Model SB1018 SAFETY For Machines Mfg. Since 8/09 Additional Metal Bandsaw Safety 1. Blade Condition. A dull or damaged blade can break apart during operation, increasing the risk of operator injury. Do not operate with a dull, cracked or badly worn blade. Inspect the blade for cracks or missing teeth before each use. 2. Hand Placement. Hands could be cut by the blade or crushed when lowering the headstock. Never position fingers or thumbs in line with the cut or under the headstock while it is moving.

Model SB1018 O P E R AT I O N For Machines Mfg. Since 8/09 OPERATION Operation Overview To complete a typical cutting operation, the operator does the following: The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so they can more easily understand the controls discussed later in this manual. 1. Examines the workpiece to make sure it is suitable for cutting. 2.
For Machines Mfg. Since 8/09 O P E R AT I O N Model SB1018 Description of Controls & Components Refer to Figure 24 and the following descriptions to become familiar with the basic controls and components used to operate this machine. A. B. C. Downfeed Rate Adjust Knob: Controls the speed at which the blade lowers into the workpiece. D. Downfeed Valve: Controls the starting and stopping of the headstock downfeed. E. F.
O P E R AT I O N Model SB1018 Blade Selection E. Selecting the right blade for the cut requires a knowledge of various blade characteristics. This section breaks down blade characteristics to help the reader make an informed decision about what blade to use for a given operation. Blade Terminology A B C F E H D G Figure 25. Bandsaw blade terminology. B. Kerf: The width of the cut made during op- eration. Tooth Set: The distance each tooth is bent left or right from the blade. C.
O P E R AT I O N For Machines Mfg. Since 8/09 Model SB1018 Tooth Set Three common tooth sets are alternate, wavy, and raker (see Figure 26). Each removes material in a different manner to make the kerf in the workpiece. Standard (or Raker) Raker Wavy Alternate Variable Pitch (VP) Variable Pitch Positive Rake Hook (or Claw) Figure 26. Bandsaw blade tooth sets. Alternate: An all-purpose arrangement with teeth bent evenly left and right of the blade. Generally used for milder metals.
O P E R AT I O N Model SB1018 Blade Pitch (TPI) The chart below is a basic starting point for choosing teeth per inch (TPI) for variable pitch blades and standard raker set bi-metal blades/ HSS blades. However, for exact specifications of bandsaw blades that are correct for your operation, contact the blade manufacturer. To select the correct blade pitch: 2.
O P E R AT I O N For Machines Mfg. Since 8/09 Model SB1018 Blade Changes Change blades when they become dull, damaged, or if the operation requires a different type of blade. Bla de Tra vel To change the blade on the bandsaw: 1. DISCONNECT BANDSAW FROM POWER! 2. Raise the head of the bandsaw, then remove the wheel access cover. 3. Loosen the tension knob and slip the blade off of the wheels. 4.
Model SB1018 O P E R AT I O N For Machines Mfg. Since 8/09 blade selection Blade Tension Blade Breakage Proper tension is essential to avoid vibration, twist, or`slippage on the wheels. A correctly tensioned blade provides long life, straight cuts, and efficient cutting. Many conditions may cause a bandsaw blade to break. Some of these conditions are unavoidable and are the natural result of the stresses placed on the bandsaw; other causes of blade breakage are avoidable.
For Machines Mfg. Since 8/09 O P E R AT I O N Model SB1018 Blade Care & Break-In Blade Speed 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. 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.
O P E R AT I O N Model SB1018 For Machines Mfg. Since 8/09 Blade Speed Chart The chart in Figure 35 offers blade speed guidelines for various metals, given in feet per minute (FPM) and meters per minute (M/Min). Choose the closest available speed on the machine, then adjust the feed rate as necessary, using the appearance of the chips produces as a guide. Refer to the Chip Inspection Chart that follows for recommendations on adjusting your operation based on the appearance of the chips produced.
O P E R AT I O N For Machines Mfg. Since 8/09 Model SB1018 Downfeed Rate Angle Cuts The downfeed valve starts and stops headstock downfeed. The headstock can be swiveled to cut angles 0°–45° to the right and 0°–60° to the left for a total swing of 105° The downfeed rate is adjusted by turning the downfeed rate adjust knob (Figure 37). Turning the knob clockwise decreases the downfeed rate and turning the knob counterclockwise increases the downfeed rate. Cuts to the Right 1.
Model SB1018 O P E R AT I O N Cuts to the Left If you need to make a cut from 45° to 60°, you will have to make the cut to the left, which will require moving the vise to the right side of the machine. 1. DISCONNECT BANDSAW FROM POWER! 2. Support the vise with one hand and remove the two cap screws that secure the vise to the machine base, then set the vise aside. 3. 4. Lift the headstock to the upmost position, then close the downfeed valve to prevent it from lowering. For Machines Mfg.
For Machines Mfg. Since 8/09 O P E R AT I O N Work Stop 2. The work stop allows you to repeat cuts at the same length. Model SB1018 Loosen the knob shown in Figure 42 and slide the blade guide to within 1⁄2" of the workpiece, then re-tighten the knob. Blade Guide To adjust the blade guide: 1. DISCONNECT BANDSAW FROM POWER! 2. Insert the work stop rod approximately 3⁄4" into the vise base. 3. Tighten the base set screw (Figure 41). ! Knob Figure 42. Blade guides.

Model SB1018 SERVICE Service Blade Tracking 5. For Machines Mfg. Since 8/09 Use the blade tension knob to release the blade tension, as shown in Figure 46. ! Blade tracking describes the way the blade rides on the bandsaw wheels. A properly tracking blade will ride approximately 1⁄16" from the blade shoulder without touching it and will not wander back and forth when the blade is running.
SERVICE For Machines Mfg. Since 8/09 Model SB1018 Blade Guide Bearings Squaring Blade The blade guide bearings must support the blade correctly to make cuts that are perpendicular to the table surface. One bearing on each assembly has an eccentric shaft that can be adjusted to properly support the blade. The bearings are secured in place by a hex nut and lock washer, as shown in Figure 47. Frequently check and adjust this setting.
SERVICE Model SB1018 For Machines Mfg. Since 8/09 V-Belt Pulley If the blade stops moving while the motor is still running, the V-belt may be slipping and will need to be tightened. Deflection To tighten the V-belt: 1. DISCONNECT BANDSAW FROM POWER! 2. Open the belt cover, then loosen the belt tension bolt shown in Figure 49 to allow the motor to pivot. Pulley Figure 50. Belt deflection.
