Skate Sharpening Machine Basics
Skate sharpening machines use a stone grinding wheel to create a U-shaped channel down the length of a skate blade. This results in sharp edges along either side of the blade, allowing skaters to grip the ice and even perform turns and tricks. Whether you wear figure or hockey skates, proper skate sharpening is critical to your performance and enjoyment on the ice.

Parts
-
A standard skate sharpening machine consists of a heavy-duty steel frame, which helps to hold the machine stationary during the sharpening process. Within the frame is a stone grinding wheel. This grinding wheel rotates very quickly and is powered by a motor built into the machine. A diamond-tipped stylus is positioned above the wheel that allows users to shape the wheel to create the desired sharpness on each pair of skates. It also includes some form of clamping system, which allows the user to position the skate blade close to the grinding wheel.
Types
-
The primary distinction between different types of skate sharpening machines lies in the orientation of the wheel. When the wheel sits perpendicular to the work surface, it generally rests on a hinged arm. On this type of machine, the skate blade is clamped in place, and the user brings the wheel down to reach the blade.
When the wheel is positioned parallel to the work surface, it often remains fixed in position on the frame. In this type of application, the skate blade fits into a track, which the user then moves back and forth along the wheel during sharpening.

Setup
-
Proper setup is key to a successful skate sharpening job. First, the user must adjust the position of the skate blade so that it is directly centered against the grinding wheel. If this process is not complete, one edge of the blade will likely end up sharper than the other. Next, the user must use the diamond-tipped stylus to "dress" the blade. During dressing, the user shapes the edge of the stone based on the desired radius of the blade. The smaller the radius, the sharper the skate will feel to the skater. A large radius results in a shallow sharpening job, which may be preferable to some users.
Maintenance
-
Skate sharpening machines require regular maintenance to ensure a high level of performance. The diamond stylus may wear out over time and must be replaced so the stone can be dressed properly. The wheel itself wears down after multiple sharpenings and will also require replacement after a period of time.
Skate sharpening machines also produce a large amount of steel dust as they grind metal blades. Users can keep this dust at bay with a specialty ventilation system. The machine and surrounding area should also be cleaned regularly to keep excess dust from building up.
