burr filer Interview Questions and Answers

1. What is a burr filer?

   • Answer: A burr filer is a skilled machinist who uses various filing techniques to remove burrs (sharp edges or projections) from machined parts, ensuring a smooth, safe, and functional finish.

2. What types of files are commonly used in burr filing?

   • Answer: Common file types include flat files, half-round files, round files, triangular files, square files, and various specialty files like needle files or rat-tail files, chosen based on the shape and size of the burr.

3. Explain the importance of proper filing technique.

   • Answer: Proper technique ensures a consistent, smooth finish, prevents damage to the workpiece, minimizes material removal, increases efficiency, and promotes safety by avoiding injury from sharp edges or file slippage.

4. Describe the different filing strokes used in burr filing.

   • Answer: Common strokes include push strokes (forward and backward), cross-filing (at a 90-degree angle to the previous stroke), and draw filing (pulling the file towards the operator).

5. How do you choose the right file for a specific burr?

   • Answer: File selection depends on the burr's shape, size, and location. A flat file is suitable for flat surfaces, a half-round file for curved surfaces, and needle files for small, intricate areas.

6. What safety precautions are necessary when using files?

   • Answer: Always wear safety glasses, use a file handle for better grip and control, avoid excessive pressure, keep files sharp and clean, and never file towards yourself or another person.

7. How do you maintain the sharpness of your files?

   • Answer: Regularly clean the files with a wire brush to remove debris, use a file card to clear out clogged teeth, and consider using a file sharpening stone for severely dull files.

8. What are some common mistakes made by burr filers?

   • Answer: Using the wrong type of file, applying too much pressure, filing in one direction only, neglecting file maintenance, and ignoring safety precautions.

9. How do you determine the correct amount of material to remove when filing a burr?

   • Answer: Remove only enough material to eliminate the burr without altering the part's dimensions or creating new imperfections. Light, controlled strokes are key.

10. What is the difference between a single-cut and a double-cut file?

    • Answer: Single-cut files have a single row of teeth, making them ideal for finishing and smoothing, while double-cut files have two rows of teeth, offering faster material removal but a rougher finish.

11. How do you handle different materials when burr filing? (e.g., steel, aluminum, plastics)

    • Answer: Different materials require different filing techniques and possibly different files. Harder materials like steel may require more pressure and sharper files, while softer materials like aluminum require lighter pressure to prevent damage.

12. Explain the importance of deburring in manufacturing.

    • Answer: Deburring is crucial for ensuring part safety, preventing damage to other components, improving the aesthetic quality, enabling proper assembly, enhancing surface finish, and extending product lifespan.

13. Describe your experience with different types of deburring equipment (besides hand files).

    • Answer: [The answer should detail experience with power tools like belt sanders, vibratory finishers, abrasive blasting equipment, etc., if applicable. If no experience, the candidate should honestly state this and express willingness to learn.]

14. How do you inspect your work after deburring?

    • Answer: Visual inspection using magnification if necessary, feel for remaining burrs, and potentially using measuring instruments to ensure dimensional accuracy hasn't been compromised.

15. What are the common causes of burrs?

    • Answer: Burrs are commonly caused by machining processes such as drilling, milling, sawing, punching, and shearing. Improper tooling, excessive cutting forces, and dull tools can all contribute.

16. Describe a time you had to troubleshoot a deburring problem.

    • Answer: [The candidate should describe a specific situation, the problem encountered, the steps taken to identify the cause, and the solution implemented. This demonstrates problem-solving skills.]

17. How do you prioritize tasks when you have multiple parts to deburr?

    • Answer: Prioritization depends on factors like due dates, part complexity, order volume, and urgency. A system like First In, First Out (FIFO) or prioritizing urgent orders can be effective.

18. What are some common materials you've worked with while deburring?

    • Answer: [List specific materials such as steel alloys, aluminum alloys, plastics, brass, copper, etc.]

19. How do you ensure consistent quality in your deburring work?

    • Answer: Consistency is achieved through proper training, adherence to established procedures, consistent application of techniques, regular self-inspection, and use of appropriate tools and equipment.

20. What are your strengths as a burr filer?

    • Answer: [List relevant strengths such as attention to detail, manual dexterity, patience, problem-solving skills, ability to follow instructions, and commitment to safety.]

21. What are your weaknesses as a burr filer?

    • Answer: [Choose a weakness and explain how you are working to improve it. For example: "I sometimes struggle with repetitive tasks, but I'm actively working on improving my focus and efficiency through techniques like short breaks and mindful work habits."]

22. Why are you interested in this burr filer position?

    • Answer: [Express genuine interest in the company, the specific role, and the opportunity for growth and development. Highlight your skills and how they align with the job requirements.]

23. Where do you see yourself in five years?

    • Answer: [Express ambition to grow within the company, learn new skills, take on more responsibility, or potentially move into a supervisory role. Show that you're looking for long-term commitment.]

24. What is your salary expectation?

    • Answer: [Research the average salary for similar roles in your area and provide a realistic range.]

25. Do you have any questions for me?

    • Answer: [Ask insightful questions about the company culture, the team, the specific responsibilities of the role, opportunities for training, and company growth prospects.]

26. [Question 21] What is the importance of using proper lubrication when filing?

    • Answer: Lubrication reduces friction, extending the life of the file and preventing the file from becoming clogged with metal particles. It also creates a smoother filing action and reduces the risk of scratching the workpiece.

27. [Question 22] How do you deal with a file that becomes clogged with metal particles?

    • Answer: I would clean the file using a wire brush to remove the metal particles. A file card can also be used to clear out clogged teeth between the cuts.

28. [Question 23] What are the different types of burrs you might encounter?

    • Answer: I may encounter various types of burrs depending on the machining process, including sharp edges, protruding material, ragged edges, and even small chips of metal left behind after cutting.

29. [Question 24] How do you handle burrs on internal features of a part?

    • Answer: Internal burrs require specialized tools like needle files, small rotary tools, or even abrasive stones depending on the size and shape of the internal feature. Care must be taken to avoid damaging the part.

30. [Question 25] Describe your experience with different types of file handles.

    • Answer: I am familiar with different file handles, including those made of wood, plastic, and metal. The choice of handle depends on the file size and personal preference, ensuring a secure grip and control during filing.

31. [Question 26] Explain the concept of "draw filing."

    • Answer: Draw filing involves pulling the file across the workpiece, applying even pressure and maintaining a consistent angle. This technique is typically used to create a smooth, even finish.

32. [Question 27] How would you handle a situation where a part is damaged during deburring?

    • Answer: I would immediately stop work, report the incident to my supervisor, and assess the damage. Depending on the severity, I may try to repair the part or flag it as scrap.

33. [Question 28] What is your experience with using magnification tools during deburring?

    • Answer: [Answer should describe experience with magnifying glasses, jeweler's loupes, or microscopes to detect small burrs and ensure a high-quality finish. If no experience, honesty is key]

34. [Question 29] How familiar are you with different types of abrasives besides files?

    • Answer: [Answer should list knowledge of sandpaper, emery cloth, abrasive belts, abrasive blasting media, etc.]
