Vertical Grinder

Ingersoll Rand Vertical Grinders is industrial grinders primarily used for heavy-duty material removal jobs. The units feature high-performance dual diamond grinding motors that are capable of producing extremely high-quality grinds in a short period of time. These machines are also commonly found in fabricating plants, foundries, welding shops, shipyards and industrial mills. These versatile machines can perform the tasks of crosscutting, drilling, grinding and cutting and are ideal for large and small work.

A vertical grinder basically has a spindle which rotates on two parallel axes. The two axes can be turned in different directions by rotating the spindle in one direction and locking the turning direction in another. This provides greater control during the workpiece turning process and produces less distortion at the workpiece surface.

An alternative to the vertical grinder is the horizontal grinder that features an open frame construction with two horizontal axes. The horizontal grinder is suitable for workpieces that need to be ground at a faster rate than the vertical model. The two horizontal axes of the horizontal grinder can be turned in opposite directions, thus providing greater control over the grinding action. This type of machine is often used in applications where the work piece requires a high degree of accuracy for intricate designs or machining operation.

Most vertical grinders use one setup type that requires a chuck base that can rotate and lift workpieces horizontally. Cylinder assemblies or wheels are fixed to the top of the chuck and support a series of vertically mounted spindles. The other setup type is called a centered chuck. In a centerfeed chuck, the spindle unit is located inside the chuck, while the motor and drive housing is positioned above the workpiece. With this setup, there is only a single vertical grinder axis, while a horizontal one is available on some units.

The main advantage of a vertical grinder is its capability to produce fine cuts with minimum distortion. In order to achieve maximum accuracy in any workplace, the vertical movement of the grinding blade across the workpiece should be almost zero. In practice, this limit is not met because of several factors such as inaccurate rotational speeds and poor blade clearance. The blade clearance is especially important because it limits how far the workpiece can be moved during the cutting process and increases the risk of sloping surfaces. Vertical grinders with greater blade clearance have lower levels of sloping than horizontal ones. This type of grinding equipment also produces less distortion.

Another advantage of the vertical grinder is that it has fewer moving parts compared to other types of machines. The most obvious moving part in this type of machine is the spindle wheels. The wheels can be fixed or mobile depending on the type of operation. In addition, the spindle wheels are usually of uniform size and are made of steel. In general, these wheels are more expensive than those for horizontal wheels, but the advantages they provide make up for the extra cost.
