Capabilities

The Ziersch ZT 820 is a precision surface grinding machine designed to produce flat, smooth, and dimensionally accurate surfaces on metal parts. With a generous sanding range of 2000x900mm and a powerful 22kW spindle, it handles mid to large-scale workpieces efficiently. The machine offers precise control across all three axes, with feed rates ranging from 0.001mm/min (vertical) to 30,000mm/min (longitudinal), making it suitable for both rough grinding and fine finishing operations.

Industries & Uses

This type of machine is essential in metalworking shops, tool and die facilities, automotive suppliers, and precision engineering companies. It's used to grind flat surfaces on dies, molds, gauges, and finished metal components where surface finish and dimensional tolerance are critical. Any business producing or finishing metal parts to tight specifications—from small job shops to larger manufacturing operations—relies on equipment like this.

What to Check When Buying

When inspecting a used surface grinder, focus on the grinding wheel condition (check for cracks or uneven wear), the magnetic clamping plate's holding strength, and spindle runout, as these affect accuracy. Ask for maintenance records, especially regarding spindle bearing service and any repairs. Verify the machine's geometry by checking calibration reports if available. Also confirm the power supply specifications match your facility, as the 22kW motor is substantial.
