Savvy manufacturers never stop looking for ways to reduce costs and improve productivity… While the up front price of electrical energy tools is undoubtedly attractive, pneumatic tools offer a lower total price of ownership and greater throughput in the lon run.
Industrial air grinders offer a completely different value proposition than electric grinders. They’re engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are becoming more popular due to the benefits provided in terms of their cost. Adopting air powered grinders results in greater financial savings through the entire life of the tool.
In this post, we explore 5 clear cut benefits afforded by way of industrial grade pneumatic grinders.
1. No Risk of Electric Shock
Grinders of all varieties are generally utilized in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a threat to operator safety resulting from electrical shock. Furthermore, metal fabricators often count on flammable chemicals, like acetone, to scrub and prep metals just before welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations can be higher when employed in confined spaces like those located in the mining and tank cleaning industries. On the other hand, air tools require no electricity, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer workplace which decreases the probability of generating OSHA violations. To put it simply, air tools are safer than electric tools because an air hose will not emit a spark and can be found in wet conditions.
2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders offer a better capacity to weight ratio than electric grinders. To put it simply, pneumatic grinders produce more horsepower inside a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the power of their tools from the wattage fed into their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not produced in electric tool specifications is the power fed in to the motor is not same wattage that concerns the spindle in the tool. The truth is, only 50% to 60% of the rated wattage actually arrives to the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will provide that very same volume of power to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for just a moment. If increasing worker output is a priority to your operation (then when is it not?), pneumatic grinders can help you meet your objectives. When working with grinders of all sorts, Revolutions Per Minute (RPM) play a critical role inside the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally in a specific RPM. Fortunately, modern pneumatic grinders include a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by regulating the air-flow for the tool. Since the operator places downward pressure for the abrasive, the governor “opens up”, increasing venting on the motor and ensuring the correct spindle speed.
4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, an item Manager for Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and as well as heat – dropping them in water, or baking them with a hot sun doesn’t help either.” By their very nature electric motors use a rated duty cycle which have to be respected. Without having a periodic rest, the heat generated by the motor itself will diminish performance and in the end cause premature tool failure. In reality, for each 4 minutes running, a power grinder is made to get one minute of rest.
Furthermore, the generation of particles is built into any material removal process. Using the open grate style motor compartments essential for cooling, electric tool motors are more prone to the accumulation of the dust and dirt. In comparison, Industrial Grade Air Tools were created designed for use in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools use a 100% duty cycle, meaning they are built to run 24 hours a day 7 days a week (when combined with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not Fibreglass which makes them more up against the impact from repeated drops. Pneumatic grinders can also be used underwater in the event the exhaust is vented above the surface!
5. Ease of Servicing and Sustainability
An advert grade grinder is not a disposable piece of equipment and doesn’t immediately find themselves in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders could be tuned up and turn into periodically rebuilt many times over. The common electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at least, a fresh group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a really industrial grade air grinder can increase to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits can be purchased that have the most typical wear parts.
