[workpiece：hard chrome plating 600ｘ400]

Workpiece is hard chrome plating. Conventional wheel caused loading and grinding sound cecame loudly with grinding 0.03mm. So, this wheel often needed dressing. However, Dolce can grind 0.1mm with no problem. Dolce is less- wearing andmakes grinding time short.

[workpiece：hard chrome plating, SUS304, hastelloy]
[workpiece speed：13m/min]

This operation was difficult because of burning and scratches conventionally. However dolce causes few loading and burning.Therefore, this good grinding performance makes this operation easy. Moreover, dolce can grind SUS304 as well as plating.

[workpiece：cast iron 1200x900]

Ceramic wheel was used in the past. This wheel speed is 1319m/min, table feeding speed is 40m/s, cutting depth is 3μm. However, dolce provides good performance and fine roughness even if grinding condition becomes hard. Therefore, dolcemakes grinding time short.

[workpiece：SUS304 Φ300x1000L]

The over wheel had been used for plating, but workpiece was changed to thermal spray ,aterial from plating. So, this conventional wheel often caused loading and this grinding performance became worse. However, dolce causes few loading and provides fine surface.

[workpiece speed：28.6m/min]

Conventional wheel often caused chattering. So, this wheel needed dressing many times and an operator could not leavegrinfing machine. However, dolce can grind to last finish grinding and causes no chattering with only first dressing. Moreover,the operator can leave grinding machine and can do other work. This is a great merit.
