Nature offers a wide range of wood types, which hinders the smooth cycling of non-varnished profiles and frames made of rough wood .
Our thirty-year experience has given us the chance to plan and develop a category of abrasive wheels hard enough to be used on any type of wood with a high performance and finishing level.
These abrasive wheels share quite the same construction features, even though each wheel , owns a specific field of application. For this reason, before describing them in detail, it is necessary to go through some general considerations:
LG Wheel: covers all types of wood; however, the customer should consider what has been said on point C of this notice. This is a basic wheel suitable for profiles’ sanding cycles that provides a high level of performance. The high-quality standard of the grit and binder used to produce it, ensures a satisfactory finish without alterations of the wood fibre and natural colour.
LG … M – LG … MM Wheels: Although deriving from LG category, these abrasive wheels are slightly softer whilst guaranteeing the same sanding and finishing characteristics. These particular abrasive types play a primary role within the sanding cycle: they ensure a perfect “burn-effect free” result. They can be installed on machines characterized by a low ratio between feed and rotation speed of the wheel (LG … M wheels : wheel rotation speed 1.400 rpm and feed speed 15 – 20 m/min; or LG … MM wheels: wheel rotation speed 1.400 rpm and feed speed 10 – 25 m/min.).
Due to special needs, the feed speed can be further reduced (below 10 m/min.); in this particular case it will be necessary to modify the wheel’s speed, taking into account that in order to achieve an acceptable result the speed must not fall below 800-900 rpm.
LGR wheel: a particular wheel type characterized by a high aggression level for which special hard grit and shearing resistance are needed. It is mainly used for work on very hard woods or woods with serious moulding deficiencies.
