This cell uses a collaborative robot with a force-controlled floating spindle, grinding and polishing along the part contour with real-time force feedback — holding constant pressure as it hugs the curve. Results speak: yield reaches ninety-eight percent, rework drops sharply, both shifts run continuously, and workers are pulled out of the dust and vibration entirely.

The problem
Three pits of manual grinding. Dust and noise harm health and make hiring hard. Hand pressure varies, so surface finish drifts within one batch. And rework piles up — over-grinding scraps parts, under-grinding sends them back — capping yield.
The solution
This cell uses a collaborative robot with a force-controlled floating spindle, grinding and polishing along the part contour with real-time force feedback — holding constant pressure as it hugs the curve.
In detail
Force control is the key: whatever the incoming stock, the spindle presses at the set force — over- and under-grinding both eliminated, the surface even and consistent.
Complex curves and edge chamfers are tracked precisely, with surface accuracy down to the 0.05 mm range — consistency far beyond a human touch.
The results
Results speak: yield reaches ninety-eight percent, rework drops sharply, both shifts run continuously, and workers are pulled out of the dust and vibration entirely.
Flexibility & changeover
Changeover is simple: drag-to-teach plus program templates mean a new part or abrasive is just a program change — mixed variants still get constant-force contact.

- From flats to curves, a collaborative robot turns grinding into a constant-force, consistent, flexible standard process. This is EVST — we make line automation real.
FAQ
What makes this different from manual operation? Three pits of manual grinding. Dust and noise harm health and make hiring hard. Hand pressure varies, so surface finish drifts within one batch. And rework piles up — over-grinding scraps parts, under-grinding sends them back — capping yield.
What are the measurable results? Results speak: yield reaches ninety-eight percent, rework drops sharply, both shifts run continuously, and workers are pulled out of the dust and vibration entirely.
How hard is changeover to a new part or model? Changeover is simple: drag-to-teach plus program templates mean a new part or abrasive is just a program change — mixed variants still get constant-force contact.
