Top 10 Questions for Glass Sander Interview

1. What are the different abrasive materials used in glass sanding?

Abrasive materials used in glass sanding include:

• Diamond
• Boron carbide
• Cerium oxide
• Silicon carbide

2. Describe the process of edge-smoothing glass

Flat edges

• Use a diamond sanding wheel to create a slight chamfer on the edge
• Follow with a finer-grit wheel to smooth the chamfer

Beveled edges

• Use a series of sanding wheels to create the desired bevel
• Start with a coarse-grit wheel and gradually move to finer grits

3. What are the safety precautions to observe when sanding glass?

Safety precautions include:

• Wear appropriate safety gear (respirator, gloves, eye protection)
• Secure the glass properly to prevent movement during sanding
• Use a well-ventilated area or exhaust system to remove dust
• Handle glass edges carefully to avoid cuts

4. Explain the difference between single-pass and multi-pass sanding

• Single-pass sanding involves making a single pass over the surface with a sanding tool
• Multi-pass sanding involves making multiple passes with the sanding tool, using different grit sizes

5. What factors affect the sanding speed of glass?

• Type of abrasive material – Different abrasives have different cutting rates
• Grit size of the abrasive – Finer grits remove material more slowly
• Speed of the sanding tool – Faster speeds can result in higher sanding rates
• Condition of the glass surface – Damaged or uneven surfaces may require more sanding

6. What are the different types of sanding machines used in glass sanding?

• Handheld sanders – Used for small-scale or intricate sanding
• Bench grinders – Used for sanding flat or curved surfaces
• CNC sanders – Used for automated, high-precision sanding
• Robotic sanders – Used for complex or dangerous sanding applications

7. How do you determine the appropriate grit size for sanding glass?

Factors to consider include:

• Desired finish – Rougher finishes require coarser grits, while finer finishes require finer grits
• Type of glass – Different glass types have different sanding requirements
• Sanding machine – Different machines may require different grit sizes

8. What techniques can be used to achieve a high-quality finish when sanding glass?

• Use a sharp abrasive – Dull or worn abrasives will produce poor-quality finishes
• Maintain a consistent sanding speed – Varying the speed can result in uneven finishes
• Use a light touch – Applying too much pressure can result in chipping or scratching
• Keep the glass surface clean – Dust and debris can interfere with the sanding process

9. How do you inspect a glass surface after sanding to ensure it meets specifications?

• Visual inspection – Inspect the surface for scratches, chips, or other defects
• Dimensional inspection – Measure the surface to ensure it meets the required dimensions
• Surface roughness measurement – Use a profilometer to measure the surface roughness and ensure it meets the specified tolerance

10. What are the common mistakes made by glass sanders and how can they be avoided?

• Using the wrong grit size – Using too coarse of a grit can damage the glass, while using too fine of a grit can result in a slow sanding process
• Applying too much pressure – Applying too much pressure can result in chipping or scratching the glass
• Not using a sharp abrasive – Dull or worn abrasives will produce poor-quality finishes
• Not cleaning the glass surface properly – Dust and debris can interfere with the sanding process and result in poor finishes

Glass Sanders are skilled craftspeople who use specialized equipment to smooth, shape, and polish glass surfaces. They play a vital role in creating a wide range of glass products, including windows, mirrors, and decorative pieces.

1. Sanding and Polishing Glass
