5 Benefits Of Using Air Powered Grinders In Place Of Electric
Savvy manufacturers never stop searching for ways to website and improve productivity… While the beforehand cost of electrical power tools is without a doubt attractive, pneumatic tools give a lower price tag of ownership and greater throughput over time.
Industrial air grinders offer a completely different value proposition than electric grinders. They’re engineered for longevity, efficiency, and above all safety. Air powered grinders are gaining in popularity due to benefits provided in terms of their cost. Adopting air powered grinders leads to greater financial savings during the entire life of the tool.
In this article, we explore 5 clear benefits afforded using industrial grade pneumatic grinders.
1. No Risk of Electric Shock
Grinders of all varieties are frequently used in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a hazard to operator safety resulting from electrical shock. Furthermore, metal fabricators often count on flammable chemicals, like acetone, to wash 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 doing work in confined spaces such as those located in the mining and tank cleaning industries. As opposed, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer work environment which lessens the chance of generating OSHA violations. The bottomline is, air tools are safer than electric tools because a cloak hose will not emit a spark and can be used in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders give a better power 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 potency of their tools by the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications could be that the power fed to the motor is not the same wattage that arrives to the spindle of the tool. The truth is, only 50% to 60% of the rated wattage actually involves the abrasive or accessory. As opposed, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will give that very same amount of capacity to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside as it were. If increasing worker output can be a priority for the operation (so when is it not?), pneumatic grinders may help you meet your primary goal. When you use grinders regardless of the sort, Revolutions Each and every minute (RPM) play an important role from the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to complete optimally at the specific RPM. Fortunately, modern pneumatic grinders include a speed control mechanism, (also called a governor), that ensures proper RPM by governing the venting on the tool. As the operator places downward pressure about the abrasive, the governor “opens up”, increasing venting towards the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, a product or service Manager for Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and also 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 has to be respected. Without a periodic rest, heat generated from the motor itself will diminish performance and finally cause premature tool failure. In reality, for every 4 minutes running, an electrical grinder is made to have one minute of rest.
Furthermore, the generation of particles is inherent in any material removal process. Using the open grate style motor compartments needed for cooling, electric tool motors will be more prone to the buildup of dust and debris. In comparison, Industrial Grade Air Tools are made specifically 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 are made to run 24 hours a day Seven days a week (when in combination 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 could even be used underwater in the event the exhaust is vented over the surface!
5. Ease of Servicing and Sustainability
An advert grade grinder is not an disposable device as well as doesn’t immediately end up in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders could be tuned up and turn into periodically rebuilt often over. The typical electric tool maintenance interval is between 60 and 120 hours after which the tool will typically need, at a minimum, a fresh pair of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a totally industrial grade air grinder can run up to 2000 hours between tune-ups. When it’s time to service your air tools, convenient and clearly labeled kits can be purchased that includes the most typical wear parts.
