Why Is Some Vertical Grinders Better Than Others?
When it comes to hand pneumatic machines, many workers in manufacturing, construction, foundry & castration plants only think about the type of rotating discs when selecting their pneumatic power tool. But this isn’t all. There are so many factors to take into consideration when making this decision that it’s easy to get side tracked. Here’s some advice on when to employ a vertical grinder vs a vertical grinder for the task at hand.
Although it may be a common question, the vertical grinder vs the type 6 rotating disc type is often asked among foundry operators, manufacturers, fabricators and even craftsmen. The answer is simple – and straight forward. The type 6 tends to work better on larger surface areas, especially when grinding larger alloy wheels. Also, the size of the wheel itself can greatly reduce waste during grinding, which leads to a significant cost savings when purchasing one.
In regards to grinding larger alloy wheels, the vertical grinder certainly has its advantages. It is, however, a much slower process. This type of grinder can even be used in tandem with the type 6 wheel to achieve optimal results. In addition to these two types of grinding, there is the ever popular vertical drilling, which is perfect for drilling into larger diameter holes without needing any type of pneumatic power source. Each of these grinding options are ideal for different jobs and each can be used individually or in conjunction with other vertical grinders.
The next question that comes to our mind is the question of how much horsepower does each vertical grinder need to complete the same task? Again, the answer is quite simple. The higher the RPM of the vertical grinder, the less horsepower it takes to grind the same diameter hole. So if you need to grind a hole in the size of a dime, all you would need to do is turn the vertical grinder at a high RPM and the hole would be ground the same in diameter as well. Of course, the more horsepower you have the faster your vertical grinder will move, which means the higher the RPM, the quicker the hole would be ground.
When it comes down to it, there really is no way to determine exactly how much workpiece pressure a vertical grinder will need to exert in order to grind a particular workpiece perfectly. What you can do, though, is determining how much weight an average person can lift. This will help you determine how much additional work person will need to be hired to complete this particular job alone. For those who are just starting out and working at a slow pace, a lower horsepower vertical grinder can be used simply because the additional effort is spread out over a larger area thus lessening the overall pressure required to accomplish the task.
There are some specific situations where a higher RPM vertical grinder is a better option than the more standard models. In areas that see extremely high levels of snowfall or extremely heavy traffic, there are times when a high-powered vertical grinder is needed to control the level of grinding completed per hour. Also, if you are performing work that requires extremely fast turning speeds, then you may want to opt for a vertical grinder that has larger and more durable wheels. Although, even the best brands usually only offer a top speed of approximately 55mph, there are still other specialized applications where this rate is acceptable. Lastly, if you need to grind in very narrow areas, then you can probably get by with a lower-powered model simply because of the amount of space that is available. But for general use, the best option would be to go for the top speed that your manual indicates should be your maximum speed at any given time.
