hk-5000-ug

Schmitt Europe presents a complete electronic upgrade kit for the Hofmann Hydrokompenser HK-4410 and HK-5000 grinding wheel balancer controllers.

The Hydrokompenser uses the grinding machine coolant as a balancing mass to compensate for imbalance in the grinding wheel and spindle assembly.

A filtered supply of coolant is injected into an annular container mounted inside the grinding wheel arbour or on the flange of the wheel arbour.

The mass of the coolant held in the container counteracts the imbalance in the wheel assembly.

This is done as the wheel is rotating at normal grinding speed, ensuring that optimum balance of the whole assembly is quickly achieved.

The original electronic controller used to drive the balancer was the HK-4410, which was superseded by the HK-5000.

The upgrade is plug-and-play, installing in minutes, and features Schmitt’s SB-5500-H Series modular electronic controller.

The upgrade kit comprises three parts: an SB-5500-H control unit, SB-4901 adapter cable to operate the existing Hofmann solenoid valve block, and a magnetically or stud-mounted SB-1440 vibration sensor with cable.

If the HK-5000 was interfaced with the machine PLC or CNC, an optional SB-4902 CNC interface adapter is available, meaning that no complex rewiring to the grinder PLC or CNC is required.

Many HK-5000 controllers were fixed into electronic consoles using a 19in rack mount, and this is also an option available for the SB-5500-H controller.

The electronics of the SB-5500-H offer fast and accurate in-process balancing of the wheel and spindle assembly.

Other benefits include a large, easy-to-read LCD display, multi-language firmware, and a plot vibration analysis of the whole grinding machine – useful for balancing, spindle problem solving and predictive maintenance.

The modular concept means that Schmitt’s AEMS (Acoustic Emission Monitoring System) for grinding machine gap and crash control can be simply added at any future date.

Complete Hydrokompenser systems are also available, featuring the SB-5500-H controller, and are especially useful for high-speed spindles or applications where a mechanical balance head simply will not fit.
