Improved Quality and Reduced Polish Time with Ceramet Diamond Technology
A manufacturer of high quality Swiss watches was using metal bonded diamond wheels to grind the sapphire glasses for their watches. The glass blanks were ground to various shapes and thicknesses and then transferred to a time-consuming and expensive diamond slurry polishing process.
The goal was to improve the quality of the grinding process and reduce the time required for polishing. Meister introduced a new grinding wheel utilizing its hybrid Ceramet bonding technology. Ceramet combines the porous and free-cutting properties of a vitrified bond with the wear resistance of a metal bond.
the progression from blank to final shape
The result is a wheel with high diamond grit exposure, low bond/workpiece interaction, excellent chip and coolant carrying capacity, and self-sharpening behavior.
With Ceramet the customer was not only able to speed-up the grinding process, but also achieved a surface quality that substantially reduced the subsequent polishing step. This allowed them to increase their production capacity and reduce their manufacturing cost/part. Below is a summary of the process and wheel design.
