Unlike all other sharpening machines on the market today, E-S4 automated skate sharpener’s revolutionary technology maintains the integrity of the blade profile and its performance characteristics from one sharpening to the next, for the life of the blade.

The E-S4 uses high-tech industrial controllers and precision digital drives to automatically control the speed and pressure of the sharpening. The ELITE automated skate sharpener protects the profile of the blade with exact precision. That means we preserve the performance characteristics of your blades in way which is impossible to achieve with any other sharpening system.

Prior to sharpening, the E-S4 first scans and registers the blade shape. Once the sharpening begins, the system detects changes in blade angle and position at every millimeter and adjusts speed and pressure to remove exactly the same amount of material along the length of the blade. In real time, the E-S4 uses sophisticated algorithms to react to hundreds of data points in order to accurately reproduce the existing blade profile throughout the sharpening process.

Inaccurate blade-to-wheel positioning can result in a serious compromise of blade performance. Even a few thousandths of an inch offset can result in a perceptible difference in blade edges.

Through engineering innovation, ELITE has developed a self-centering clamp system that ensures the exact center of the blade meets the exact apex of the grinding wheel, every time.

The E-S4 clamping mechanism uses two symmetrical plates to center the blade over the wheel. The E-S4 ensures the blade is fixed into the optimal position regardless of variations in blade width.

The accuracy of the self-centering clamping mechanism, combined with the precision of the steel alloy wheels, means the E-S4 automated skate sharpener delivers a perfect hollow every time.

Top players are sensitive to the most subtle variations in blade profile shape. Even differences as tiny as the width of a human hair – between blades in a pair, and between multiple sets of blades – can affect player feel and performance.

Precision begins with the profile templates which carry the shape you will copy onto the blades. ELITE profile templates are not just laser cut, but CNC-machined to tolerances of 2/1000th of an inch to guarantee consistent results.

ELITE’s blade mounting system means that the blades are profiled on their own, not on skates. This means that there is always a consistent reference point for the blades, every time they are profiled. It also allows two or four blades to be profiled at a time. All the blades will end up perfectly identical.
