A vertical grinder, sometimes referred to as an earthgrinder or vertical adze, is a handheld multipurpose tool utilized for the selective removal of tile, brick, stone, pea gravel, sod, and other construction materials. It may be used in any environment where demolition, renovation, or construction is desired. It is designed to withstand the impact of abrasive tools and large pieces of rock and concrete. It can be effectively used for breaking up solid materials and polishing the surfaces of concrete. The vertical grinder features a blade that has a diamond like surface.
The blade of the vertical grinder may be manually turned to obtain different types of grinds. The blade of this multi-purpose tool can be locked and unlocked for workplace access. One of the most common uses of the vertical grinder blade is the face grinding operation. It is frequently used in the construction of stair steps, doorways, walls, floors, foundations, buildings, bridges, and skylights.
Face Grinding: The face grinding feature of the vertical grinder allows the use of very coarse materials which are normally found in concrete work. Face grinding allows the concrete workpiece to be ground without affecting the roundness error. In concrete applications where fine roundness is desired the use of the vertical grinder with its compact design and self contained chuck can meet the needs of the project.
Compactor Grinder: The use of the compactor vertical grinder requires a source of power other than the vertical grinder blade. Most of the compactor units utilize electric motors to operate. These units are available in both vertical and horizontal styles. They are suitable for work that requires a reduced amount of grinding performance and are available in a variety of sizes to accommodate the diverse needs of the fabricator and its customers.
Compressor Grinder: The compression vertical grinding machine uses hydraulic pressure to move the workpiece into the chuck. This method is effective in reducing the chatter that results from the movement of the workpiece into the vertical grinder. This method is also effective means of producing less distortion of the workpiece and the finished product. Compression units are available in both self contained and external hydraulic styles. Hydraulic models are recommended for applications where reduced distortions are desired and for use on larger diameter pieces.
For projects requiring a higher level of accuracy, more sophisticated machining operations must be utilized. One of this machinery is the table top vertical grinder. The table-top style is mounted on a work platform or stand. It utilizes the principle of centrifugal force to impart rotation to the workpiece. This provides a smoother and less distorted result and allows for greater accuracy than its counter-rotating counterpart. While more expensive than most of the other styles of vertical grinder available in the market, this particular variant provides excellent performance for a more precise output.
