How do you ensure the accuracy of the punched holes?
- Answer: Accuracy is ensured through careful setup, including precise alignment of the template and material, regular maintenance of the machine, and verification of the punch depth and spacing. I also conduct regular quality checks throughout the process.
-
Explain the setup process for a duplicator punch.
- Answer: The setup process involves selecting the correct die and punch for the job, securely clamping the template and material, adjusting the machine settings for punch depth and speed, and performing a test run to verify accuracy before starting full production. This includes checking the material thickness and ensuring it aligns with the capabilities of the machine and tooling.
-
What safety precautions do you take when operating a duplicator punch?
- Answer: Safety is paramount. I always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves. I ensure the machine is properly guarded, follow lockout/tagout procedures during maintenance, and never operate the machine with loose clothing or jewelry. I also regularly inspect the machine for any signs of damage or malfunction.
