Frequently Asked Questions
-
Q: What is the difference between magnetic backing plates and metal thin plates?
A: Magnetic backing plates mount on the machine platen and create a magnetic surface for instant tool-free disc attachment — ideal for quick grit changes between grinding stages with no adhesive residue. Metal upper thin plates with PSA backing mount directly on the platen surface using pressure-sensitive adhesive, providing a flat, stable base for PSA-backed discs and lapping film in fixed single-grit setups.
-
Q: Standard vs 1/2" arbor — which do I need?
A: Standard plates mount flat on the machine platen surface without a center post. The 1/2" arbor configuration has a center hole for machines with a 1/2" center post or spindle. Check your flat lap machine's platen mounting system before ordering — most standard flat lap machines use the standard (no arbor) configuration.
-
Q: What size backing plate do I need for my flat lap machine?
A: Match the backing plate diameter to your flat lap machine's platen size. Common sizes: 6"–8" for small bench-top flat lap machines, 10"–12" for mid-size machines, 14"–18" for larger production flat lap systems, and 24" for large production polishing machines. Always verify your machine's platen diameter before ordering.
-
Q: Can I use magnetic backing plates with PSA-backed discs?
A: No — magnetic backing plates are designed for magnetic-backed discs only. PSA-backed discs require PSA backing plates or metal thin plates with PSA surface. Always match the disc backing type to the backing plate type — magnetic disc to magnetic plate, PSA disc to PSA plate.
