Burring Machine Operator Interview Questions and Answers

  1. What is a burring machine?

    • Answer: A burring machine is a piece of equipment used to remove burrs, or sharp edges, from metal parts after machining, casting, or other manufacturing processes. Different types exist, including automated and manual, using various methods like deburring wheels, brushes, or abrasive media.

  2. Describe your experience operating burring machines.

    • Answer: [This answer should be tailored to the individual's experience. Example: "I have over five years of experience operating various types of burring machines, including centrifugal barrel deburring machines and robotic deburring cells. I'm proficient in setting up machines, selecting appropriate tooling, and ensuring consistent, high-quality results."]

  3. What safety precautions do you take when operating a burring machine?

    • Answer: I always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves. I ensure the machine is properly guarded and that all safety interlocks are functioning correctly before operation. I never reach into the machine while it's running and follow all lockout/tagout procedures during maintenance.

  4. How do you identify and address common problems encountered during burring operations?

    • Answer: Common problems include inconsistent deburring, damage to parts, or machine malfunctions. I troubleshoot by checking for issues like improper tooling, incorrect machine settings, worn brushes or wheels, and material jams. I can perform basic maintenance and know when to call for assistance from a maintenance technician.

  5. Explain the different types of burring machines you are familiar with.

    • Answer: [This answer should list the types of burring machines the individual knows, e.g., centrifugal barrel deburring machines, vibratory finishing machines, robotic deburring systems, manual deburring tools. A brief description of each should be included.]

  6. How do you determine the appropriate tooling for a specific deburring job?

    • Answer: Tool selection depends on factors like the material of the part, the type and size of the burr, the desired surface finish, and the production rate required. I consider factors such as brush type, abrasive grit size, and wheel diameter when making my selection. I might consult the machine's manual or previous job specifications.

  7. How do you ensure the quality of the deburred parts?

    • Answer: I regularly inspect the parts during and after the deburring process using visual inspection and sometimes using measuring tools like calipers or micrometers to verify dimensions and surface finish. I adhere to quality control procedures and specifications provided.

  8. What is your experience with different materials used in deburring?

    • Answer: [This answer should list materials like steel, aluminum, brass, plastics, etc., and describe any special considerations for each.]

  9. How do you maintain a burring machine?

    • Answer: Routine maintenance includes regular cleaning, lubrication of moving parts, checking and replacing worn tooling, and inspecting for any signs of damage or wear. I also follow the manufacturer's recommended maintenance schedule.
