Savvy manufacturers never stop looking for ways to reduce costs and improve productivity… Even though the beforehand cost of electrical power tools is certainly attractive, pneumatic tools give a lower sum total of ownership and greater throughput in the long run.
Industrial air grinders give a totally different value proposition than electric grinders. They are engineered for longevity, efficiency, and above all safety. Air powered grinders are gaining in popularity due to the benefits provided in terms of their cost. Adopting air powered grinders brings about greater cost savings throughout the duration of the tool.
In this article, we explore 5 clear cut benefits afforded by the use of industrial grade pneumatic grinders.
1. No Risk of Electric Shock
Grinders coming from all varieties are generally utilized in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a threat to operator safety caused by electrical shock. Furthermore, metal fabricators often depend on flammable chemicals, like acetone, to completely clean 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 doing work in confined spaces including those found in the mining and tank cleaning industries. As opposed, air tools require no electricity, in addition to their rotary vane air motors generate no spark. Pneumatic grinders therefore develop a safer workplace which cuts down on likelihood 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 could be found in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders give a better chance 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 effectiveness of their tools through the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not stated in electric tool specifications could be that the power fed in the motor isn’t same wattage that arrives to the spindle in the tool. In reality, only 50% to 60% with the rated wattage actually concerns 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 capability to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is a priority on your operation (so when don’t you think?), pneumatic grinders will help you meet your primary goal. When working with grinders regardless of the sort, Revolutions Per Minute (RPM) play an important role within the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to complete optimally at a specific RPM. Fortunately, modern pneumatic grinders include a speed control mechanism, (also called a governor), that ensures proper RPM by governing the air flow to the tool. Because the operator places downward pressure on the abrasive, the governor “opens up”, increasing venting on the motor and ensuring the correct spindle speed.
4. 100% Duty Cycle + Top rated in Harsh Environments
Mitch Burdick, something Manager for Diy equipment 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 have a rated duty cycle which has to be respected. With no periodic rest, heat generated with the motor itself will diminish performance and eventually cause premature tool failure. In reality, for every single 4 minutes running, an electric grinder was designed to get one minute of rest.
Furthermore, the generation of particles is inherent in any material removal process. With the open grate style motor compartments essential for cooling, electric tool motors tend to be more prone to the accumulation of dust and debris. As opposed, Industrial Grade Air Tools were created particularly for used in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools possess a 100% duty cycle, meaning they may be designed to run 24 hours a day Seven days a week (when used with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not Abs plastic, fiberglass causing them to be more up against the impact from repeated drops. Pneumatic grinders can even be used underwater when the exhaust is vented higher than the surface!
5. Ease of Servicing and Sustainability
A commercial grade grinder is not a disposable piece of equipment and doesn’t immediately find themselves in the landfill as being a “disposable” commercial electric grinder. Pneumatic grinders can be tuned up and become periodically rebuilt many times over. The typical electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at a minimum, a fresh set of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very 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 which contain the commonest wear parts.
