Step-by-Step Guide to Operating a Keyway Slotting Machine

1. Preparation:

• Ensure the workpiece is securely mounted on the table.
• Select the appropriate cutting tool (broach, slotting cutter) and adjust its speed and feed.
• Configure machine settings (e.g., stroke length, depth of cut) according to the keyway specifications.

2. Alignment:

• Position the cutting tool perpendicular to the workpiece surface.
• Align the toolpath with the desired keyway orientation.

3. Slotting:

• Start the slotting process and monitor the progress.
• Adjust machine settings as needed to maintain optimal cutting conditions.
• Ensure adequate lubrication to minimize friction and extend tool life.

4. Completion:

• Once the keyway is complete, remove the workpiece from the machine.
• Inspect the keyway for accuracy and quality.
• Clean and maintain the machine as per manufacturer recommendations.
