Thinking of pneumatic grinders, most of the professionals in industries such as metal working, fabrication, foundries & casting plants or even shipbuilding, would only consider the type of abrasive wheels when choosing their tool, which is not enough. Here are some advice to make the right choice to get the job done.
3 Cases Where it is Best to Use Angle Grinders:
• When using abrasives wheels between 4'' (100mm) and 6" (150mm): Usually angle grinders are designed for abrasives wheels sized between 4" (100mm) and 6" inches (150mm). You may find some angle grinders designed for larger abrasive sizes, however the performance is nothing compared to a vertical grinder. Such vertical grinder is the right solution to make the most of large abrasives, as well as cup wheels.
• When maneuverability is the priority: The compact size of angle grinders allows for easy operations when working in tight areas, and makes it possible to hold the tool's overhead.
• When abrasive visibility is the priority: Thanks to their low profile, working with angle grinders ensure a good visibility on the abrasive when high precision is required for the job.
3 Cases Where it is Best to Use Vertical Grinders:
• When high power is needed: Some applications require high power, to allow operators to apply a heavy load (feed force). This is where vertical grinders excel: their large air motors can provide up to 4.5hp (3400 W) power which allows to quickly remove large amounts of material.
• When working on large components: Some casting deburring and fabrication of large structures require to cover large surfaces, or grind on long distances. In this case, abrasives wheels of 7” (180mm) and 9” (230mm) allow to work faster than with 4” (100mm) or 5” (125mm) abrasive wheels. In other words, if you are working on a big job, use bigger tools!
• When working on benches: For this specific application, the weight of vertical grinders helps the operator as it reduces the needed feed force making his job easier.
“There is a tool for each application. When making your choice, you should consider the two following things:
First, make sure the selected tool is made for running the specific abrasive dimension you need, at the correct speed.
And then, include the working preferences of the operator, to ensure ergonomics and comfort.”
Power tools are a key to productivity in the oil & gas or the metal working industry. Maintenance and production tasks must be carried out efficiently, however intensive use of vibrating power tools, such as grinders, can expose operators to Hand Arm Vibration Syndrome (HAVS). How can we reduce risks, improve productivity and reduce abrasive costs at the same time?
Calibration process is a vital step in ensuring tools are working as they should be, giving correct readings, providing a safe working environment for end-users, and ensuring that companies are upholding their legal obligations. However, calibration is often confused with accuracy and precision. Here we explore what exactly is meant by calibration and why it’s so important.
Providing a safe working environment for operators is essential, especially when using pneumatic tools and compressed air. If there is a failure in the air network and the hose is not adequately clamped, the resulting whiplash could be devastating. Failure to follow best practice can result in injuries, associated production downtime and decreased productivity.
