Developing roll for copy machine
Copy machine developing roller (sleeve)By performing centerless grinding after drawing, it is possible to manufacture ultra-high precision sleeves.
It is also possible to perform spigot machining on both end faces with high precision.
*Grooving in the longitudinal direction is also available.
Processing: Drawing → End face cutting → Centerless polishing
Tolerance: Outer diameter ±0.005 Inner diameter ±0.01 Runout 15μm or less
The runout has been proven to be less than 8μm for A3 size (L330).
