A vertical grinder, also known as a vertical digger or a disc grinder, is a type of power equipment that is most commonly used in construction and other fabrication work. It is an economical solution to a wide range of cutting requirements and has a wide variety of uses for a wide range of working conditions. In this article we will discuss some more details about vertical grinders and how they can be used in various sectors. This should help you make your decision on what type of vertical grinder you would need for your particular job.
First of all, let’s look at the different types of controls available on vertical grinders. Grinding operations can be executed in two main ways, using parallel axes and rotating axes. In both cases, the working area and the position of the work piece are fixed, and the distance and direction of operation can be set manually. The main advantage of the parallel axes is that they produce smoother and more accurate results, but they are also more difficult to program and control. The rotation axes, on the other hand, provide a bit of accuracy, but are much easier to program.
The most common use of a vertical grinder in applications where material removal is critical is to grind smooth surfaces. Grinding wheels can be either counter-balanced or counter-driven. With counter-balanced wheels, there is an additional motor that helps to balance the grinding head when it is operating over rough or uneven surfaces. When the material is removed from the grinding wheel, the motor transfers the grinding force to another surface, making sure that the ground material comes to the grinding point at the same time the force is being generated.
The second application where vertical grinder systems are used is in the context of attachment to a table or other work platform. In this application, the workpiece is clamped to the frame, and the vertical grinder attached to the workpiece transfers the grinding force from the clamps to the workpiece. The disadvantage of this system is that the workpiece is often unstable, since it must be firmly clamped to the frame. This is solved by increasing the clamping force as the workpiece is moved, thereby reducing the transfer of the workpiece energy to the clamping unit.
A vertical grinder can also be used in the context of direct machine polishing. In this application, a diamond abrasive disc is placed on a vertical spindle with teeth that either side of the disc catch tiny particles of grit or metal. This method is often used in the aerospace industry to obtain optimal results in aircraft aluminum forging. The vertical grinder in this situation is often attached to the vertical spindle directly, or indirectly through a mechanism such as a side plate. Clamping is used to hold the abrasive material against the workpiece, and the polisher uses a continuous polishing cycle to achieve optimal results.
Direct machine polishing usually utilizes a diamond abrasive disc and a fixed mandrel. The workpiece is held between the discs, and the grinding teeth of the disc are clamped to the workpiece using a vertical grinder and clamping force that is derived from an electrical motor. This system allows the operator to achieve very high grinding speeds, and the workpiece is typically cured by an ultraviolet curing process. Although this system typically produces high-quality results, it typically requires a huge investment in time and machinery.
