When it comes to pneumatic or hydraulic grinders, most professional metal working, manufacturing, foundry & casting centers only think about the kind of abrasive wheels on their particular machine when selecting their primary tool. But that’s not all. There are other things to consider when selecting a grinder. You will also want to consider if you need a pneumatic grinder, or if you will need to manually operate a hydraulic one. Here’s some information on when to use a vertical grinder vs a vertical grinder for the job.
First of all, let’s look at the pros and cons of both types. A vertical grinder generally produces less distortion than a circular grinding wheel because the workpiece sits up higher and there is more ground space. This means a smaller area is available for a small amount of the workpiece. This is good for smaller, low profile components that don’t require a large clearance area, but it can cause the higher profile workpieces to have less ground area than needed.
In addition, with a vertical grinder, there is typically only one speed control. This is fine when you are doing very small components, but there is generally not enough horsepower to generate a larger amount of speed or torque for larger pieces. The bottom line is that a motor has to run at a high rpm to produce horsepower, and you will not be able to drive the RPMs that the pulley or belt is capable of unless you purchase a more powerful model. For heavy duty work, consider stepping up to a larger belt or a larger, more powerful motor.
Another consideration to keep in mind when looking at vertical grinder options is the presence of a heavy-duty sliding plate. These plates come in various sizes and types and are used primarily for heavy-duty grinding applications. They are typically found on commercial grade grinders and are very effective at completing even very heavy-duty, commercial-grade product. However, the presence of the sliding plate can also limit the amount of vertical movement that takes place, so they are not ideal for all situations.
When searching for the ideal vertical grinding machine, it is important to consider what the main benefits are. Perhaps the most important benefit is increased productivity due to the increased roundness of the workpiece. Roundness refers to the level of uniformity in the diameter of the workpiece. With a rounder workplace, there is a reduced risk of slop and the grinding operation can be completed quicker because the workpiece does not need to travel as far along the grinding path to achieve the best results. This is important for precision component fabrication, where the work must be made to exact specifications and the faster the process, the more precise the final result. In addition to the ability to produce precision products with greater accuracy, the increased roundness can also minimize fatigue and make the operation less cumbersome.
Another benefit to be considered when looking at vertical grinder options is the ease in which different workpieces can be customized. Since the chuck is modular, there is the potential to move the vertical grinder closer or further from the workplace without having to change the workpiece itself. This gives the user the ability to move the workpiece in closer proximity to the source of the power, thereby allowing for a more efficient production process. The chuck also provides an increased level of safety due to the fact that it is mounted at one end, which prevents the sudden shock of the moving chuck striking any part of the body. The increased security of the one setup also makes it a more suitable option for mobile workers and operators.
