Operating Instructions

This section outlines the general procedures for operating your JET JMD-18 milling/drilling machine.

• Power On/Off: Locate the main power switch. Turn the machine ON only when ready to begin work and OFF immediately after completing a task or before making adjustments.
• Speed Selection: Adjust the spindle speed using the belt and pulley system accessible via the hinged belt cover. Select the appropriate speed for the material and tooling being used. Refer to a speed chart for guidance.
• Workpiece Clamping: Always securely clamp your workpiece to the worktable using appropriate vises or clamps. Loose workpieces can cause injury or damage.
• Tool Installation: Install the correct cutting tool (drill bit, end mill, etc.) into the spindle chuck or collet. Ensure it is properly seated and tightened.
• Milling Operations: For milling, carefully position the workpiece relative to the cutting tool. Use the table's X, Y, and Z axis controls for precise material removal.
• Drilling Operations: For drilling, align the drill bit with the desired hole location. Use the quill feed handle for controlled drilling depth.
• Coolant Application: For certain materials and operations, apply appropriate cutting fluid to prolong tool life and improve surface finish.
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your JET milling/drilling machine.

• Daily Cleaning: After each use, clean the machine thoroughly, removing all chips, dust, and debris from the worktable, ways, and other surfaces.
• Lubrication: Periodically lubricate all moving parts, including lead screws, gibs, and spindle bearings, according to the lubrication points indicated in the machine's diagrams (if available). Use recommended lubricants.
• Belt Inspection: Regularly inspect the drive belts for wear, cracks, or tension. Replace worn belts and adjust tension as needed.
• Electrical Inspection: Periodically check electrical cords and connections for damage. Ensure all wiring is secure.
• Tooling Care: Keep all cutting tools sharp and clean. Dull tools can lead to poor performance and machine strain.
• Storage: When not in use, store the machine in a dry, clean environment. Apply a thin coat of rust preventative to exposed metal surfaces.
