The Baileigh Industrial BS-330M is a horizontal band saw designed for metalworking applications. It features a robust construction to ensure reliable and efficient cutting of various materials.
Function Description:
The BS-330M is used for cutting metal workpieces, including rectangular, round, and square stock, at both 90° and 45° miter angles. The saw operates by feeding a continuous band saw blade through the material, controlled by a hydraulic descent system. A coolant system is integrated to lubricate the blade and workpiece, extending blade life and improving cut quality. The machine includes a vise for securing material, blade guide brackets for stability, and a control panel for operation. A laser light projects onto the cut path to assist in precise material positioning.

Usage Features:
The BS-330M is designed for ease of use and precision.
- Vise Adjustment: The vise features a handwheel for opening and closing the jaws, and a ratchet for quick adjustment. It can be pivoted for angle cutting, with bolts to secure the desired angle. The movable vise jaw can be adjusted to parallel the fixed jaw.
- Blade Guide Brackets: These brackets support the blade and can be adjusted to be as close to the vise jaws as possible, ensuring straight cuts. The left blade guide bracket is movable to accommodate different workpiece sizes.
- Descent Control: A hydraulic cylinder controls the saw bow's descent speed, which can be regulated using a descent control valve. This allows for optimal feed rates based on material type and desired cut quality.
- Blade Speed Adjustment: The machine is equipped with a mechanical variable speed control device, allowing the operator to adjust blade speed between 66-264 FPM (20-80 MPM) while the machine is running. This is crucial for cutting different materials effectively.
- Automatic Shut-Off: The motor automatically shuts off once the blade has cut through the material, preventing unnecessary operation and potential damage. The stop bolt for this function is adjustable.
- Work Stop-Bar: An adjustable stop-bar assists in repetitive length cutting, with presets for common angles (0°, 15°, 30°, and 45°).
- Coolant System: An integrated coolant pump and spray hose facilitate chip removal and blade cooling. The water gun can be used to wash off chips and debris from the work table.
- Laser Light: A laser projects a thin line onto the cut path, aiding in precise material positioning. The laser's aim can be fine-tuned by rotating and tilting it within the extension arm.
- Blade Selection: The manual provides guidance on choosing the appropriate blade type (bi-metal, regular tooth, positive rake tooth, combo tooth) and tooth pitch based on the material's type, hardness, and dimensions, emphasizing the importance of having 3-6 teeth in contact with the material during cutting.
Maintenance Features:
Regular maintenance is essential for the longevity and performance of the BS-330M.
- Daily Maintenance: Includes checking for unsafe conditions, tightening nuts and bolts, general cleaning, cleaning the coolant drain hole, topping off coolant, checking blade wear, and verifying shield and emergency stop functionality.
- Weekly Maintenance: Involves lubricating threaded components and sliding devices, applying rust inhibitive lubricant, thoroughly cleaning the machine and coolant tank, cleaning the pump suction filter, and cleaning blade guides and flywheel housings.
- Monthly Maintenance: Focuses on checking the tightness of drive wheel screws, ensuring blade guide bearings are in good running condition, and checking the tightness of motor, pump, and protection guard screws.
- Coolant Replacement: The coolant reservoir should be drained, cleaned, and refilled periodically. Baileigh B-Cool 20:1 biodegradable metal cutting fluid is recommended.
- Gear Case Lubrication: The gear box lubricant should be changed after the first 3 months of operation and annually thereafter, using MOBIL CYLINDER OIL # 600W or equivalent.
- Blade Care: Proper blade tensioning, alignment, and selection are crucial to prevent blade breakage and ensure optimal tool life. The chip brush needs periodic adjustment to ensure it touches the blade and removes chips.
- Blade Tracking Adjustment: While factory-set, adjustments can be made if tracking problems occur, requiring careful observation of the blade on the wheels while the machine is running.
- Storage: For extended periods of inactivity, the machine should be disconnected from power, the coolant reservoir emptied and cleaned, and the machine cleaned, greased, and covered.
