Savvy manufacturers never stop researching to website and improve productivity… Whilst the up front price of electrical power tools is without question attractive, pneumatic tools offer a lower total price of ownership and greater throughput in the long run.
Industrial air grinders provide a very different value proposition than electric grinders. They’re engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are increasing in popularity as a result of benefits provided in relation to their cost. Adopting air powered grinders ends in greater financial savings through the entire duration of the tool.
In this post, we explore 5 clear cut benefits afforded through industrial grade pneumatic grinders.
1. No Risk of Electric Shock
Grinders of all varieties are generally found in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a risk to operator safety resulting from electrical shock. Furthermore, metal fabricators often count on flammable chemicals, like acetone, to completely clean and prep metals just before welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when working in confined spaces including those found in the mining and tank cleaning industries. In comparison, air tools require no electricity, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer workplace which decreases the probability of generating OSHA violations. In other words, air tools are safer than electric tools because a cloak hose won’t ever emit a spark and can be employed in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower within a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools through the wattage fed to their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications is that the power fed to the motor isn’t same wattage that arrives to the spindle from the tool. In reality, only 50% to 60% from the rated wattage actually comes to fruition at the abrasive or accessory. As opposed, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will provide that same volume of chance to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for just a moment. If increasing worker output is really a priority for the operation (when is it not?), pneumatic grinders can help you meet your purpose. When you use grinders of all sorts, Revolutions For each minute (RPM) play an important role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to do optimally at the specific RPM. Fortunately, modern pneumatic grinders include a speed control mechanism, (also known as a governor), that ensures proper RPM by regulating the air-flow to the tool. Because the operator places downward pressure for the abrasive, the governor “opens up”, increasing air-flow to the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, a Product Manager for Saws at Bosch says: “The two biggest threats affecting electric tool life are dirt and and warmth – dropping them in water, or baking them within a hot sun doesn’t help either.” By their very nature electric motors have a rated duty cycle which have to be respected. With out a periodic rest, the warmth generated through the motor itself will diminish performance and ultimately cause premature tool failure. The truth is, for every 4 minutes running, a power grinder is designed to have one minute of rest.
Furthermore, the generation of particles is inherent in any material removal process. With all the open grate style motor compartments essential for cooling, electric tool motors will be more vunerable to the accumulation of debris and dust. On the other hand, Industrial Grade Air Tools are created especially for use within foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning they may be meant to run Twenty-four hours a day 7 days a week (when combined with a filter regulator lubricator). Air tool housings are constructed of aluminum or steel, not Abs plastic, fiberglass driving them to more resistant to the impact from repeated drops. Pneumatic grinders can even be used underwater when the exhaust is vented above the surface!
5. Ease of Servicing and Sustainability
An industrial grade grinder isn’t a disposable item of equipment and immediately finish up in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders may be tuned up and be periodically rebuilt often over. The average electric tool maintenance interval is between 60 and 120 hours after which the tool will typically need, at a minimum, a 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 contain the most typical wear parts.
