Grinding Wheels And Their Uses
The Vertical Grinder by Tool Steel International, also called the T-GRID is an industrial grade, heavy duty grinders which can be used in a wide range of applications. The new grinder incorporates a range of innovative features and is suitable for grinding almost all types of materials from aluminum to stainless steel. The vertical grinder has a large cutting area of 28 inches and has sufficient power to easily and quickly grind small holes.
The LSS 53 Vertical Grinder is sturdy and robust enough for even the toughest rougher grinding applications making it an ideal choice for long service life. The rigid steel structure with a nodular cast iron body and vertically positioned air cooling fan blade provides impressive long life and strength. This grinder is able to grind through most types of sheet metal and comes equipped with an optional, user selectable carbon fiber grinding blade. The grinding unit is attached to a permanently mounted, high-tempered steel stand and includes a conveniently located control key to operate all controls.
The use of carbon and diamond grinding wheels ensure maximum performance and most ideal results. The smooth deck provides excellent contact with the workpiece for producing consistently hot and evenly ground ends. In addition, the smooth deck also produces less distortion at the workpiece end. This means that the vertical grinder produces better-quality products with increased accuracy and greater consistency in the sizes and shapes of the ground workpieces.
The LSS series offers two types of grinding actions – the fully automatic, or the manual, scroll vertical grinder. The fully automatic system is suitable for work involving a small variety of materials which are not very dense. The system has a clutch and two gearsets which allow it to grind through materials with high hardness or toughness. In this way, it may be used on softer alloy surfaces and stones. For other work, the manual, or semi-automatic, vertical grinder is more appropriate.
There are several advantages of using the vertical grinder. It provides a faster process and can be used to quickly zero in on a workpiece. It also leaves more time for other aspects of the work, because it does not need to stop to perform other functions. Further, the lesser number of moving parts in the vertical grinder provide increased durability, and less chance for parts to lock together or become misaligned.
However, the disadvantages of the vertical grinding machine include its slow speed, which may be slower than necessary for most projects, and the need to have a face grinding tool adjacent to the workpiece for the best result. Also, because the work piece has to stay on a flat surface, the materials must be tightly turned. Lastly, the increased size of the grinding teeth can lead to some chipping and abrasive effects to the workpiece surface. These are not as important with flat or concave surfaces.
