Savvy manufacturers never stop searching for ways to reduce costs and improve productivity… As the at the start tariff of electrical energy tools is undoubtedly attractive, pneumatic tools offer a lower total cost of ownership and greater throughput in the long run.
Industrial air grinders give you a completely different value proposition than electric grinders. They may be engineered for longevity, efficiency, and most importantly safety. Air powered grinders are becoming more popular because of the benefits provided with regards to their cost. Adopting air powered grinders leads to greater cost benefits throughout the lifetime of the tool.
On this page, we explore 5 clear cut benefits afforded by way of industrial grade pneumatic grinders.
1. No recourse of Electric Shock
Grinders coming from all varieties are frequently employed in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a hazard to operator safety caused by electrical shock. Furthermore, metal fabricators often count on flammable chemicals, including acetone, to wash and prep metals prior to welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when employed in confined spaces such as those located in the mining and tank cleaning industries. As opposed, air tools require no electricity, as well as their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer work environment which cuts down the odds of generating OSHA violations. To put it simply, air tools are safer than electric tools because an aura hose won’t emit a spark and could be found in wet conditions.
2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders give a better capability to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower in the lighter and smaller package. Misleadingly, electric tool manufacturers often classify the strength of their tools by the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not produced in electric tool specifications could be that the power fed into the motor is not the same wattage that involves the spindle of the tool. In fact, only 50% to 60% with the rated wattage actually concerns the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will give that very same level of capability to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is often a priority on your operation (so when is it not?), pneumatic grinders can help you meet your primary goal. When making use of grinders of all sorts, Revolutions Per Minute (RPM) play a crucial role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally with a specific RPM. Fortunately, modern pneumatic grinders come with a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by governing the venting on the tool. Since the operator places downward pressure about the abrasive, the governor “opens up”, increasing venting for the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, a Product 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 within a hot sun doesn’t help either.” By their very nature electric motors possess a rated duty cycle which has to be respected. Without having a periodic rest, the heat generated from the motor itself will diminish performance and ultimately cause premature tool failure. The truth is, for every 4 minutes running, an electric grinder is designed to have one minute of rest.
Furthermore, the generation of particles is inherent in any material removal process. With the open grate style motor compartments necessary for cooling, electric tool motors tend to be more vunerable to the buildup of debris and dust. In contrast, Industrial Grade Air Tools were created especially for used in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning they’re designed to run Round the clock Seven days a week (when used with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not Abs plastic, fiberglass causing them to be more resistant to the impact from repeated drops. Pneumatic grinders could even be used underwater if your exhaust is vented across the surface!
5. Simplicity of Servicing and Sustainability
An advertisement grade grinder is not an disposable item of equipment and immediately end up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders can be tuned up and turn into periodically rebuilt often times over. The typical electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at least, a brand new pair of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very industrial grade air grinder can amass to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits are available that have the most typical wear parts.
