Ski and Board Tuning

It is essential to the performance of skis and snowboards that they are correctly maintained and cared for. Often people are disappointed with snow conditions or their individual performance when it’s not often their fault, the current tune on their equipment is most likely incorrect for the conditions or improperly tuned. Your equipment should be responsive and susceptible to edge and direction changes, stable in all snow conditions, have good edge grip and have good gliding characteristics. For total ski and board performance it’s extremely important that you have all your equipment properly tuned.

SIGMA SBI Automatic Service Center for Grinding, Tuning, Deburring and Cold Waxing • 350 mm wide grinding stone • 350 mm wide grinding belt • 40 individual grinding programs (20 pre-programmed) • Divided structures on the same stone • Split feed system with 3 rollers • PCS (Pressure Compensation System)

A stone finish delivers a far superior tune to your ski or snowboard than a belt finish. With a stone ground base you end up with a flat gliding surface and a fiber free structure. Typically with a belt finish you have a concave base finish and rounded edges. The advantages of this type of finish to your ski or snowboard are

• Improved maneuverability
• Instant response to direction changes
• Better direction control
• Faster, smoother gliding
• Optimum edge grip for all slopes and snow conditions.

With the SBI stone finisher the tuner has a number of different options to choose the right structure for your base. This will provide you with the optimum stability and gliding properties for the conditions.

For convex, concave and flat bases there are different tuning methods you can use with the SBI to ensure your equipment gets the best tune. For instance there are 3 feed rollers that can be used together to feed the ski/board over the stone at any desired pressure. 3 should be used for a flat ski base, 1 feed roller should be used on the side of the ski/board for a convex base, with 2 passes the left and right side can be ground separately, for concave ski/boards only one feed wheel should be used in the centre.
