Savvy manufacturers never stop searching for ways to website and improve productivity… Whilst the in advance price of electric power tools is undoubtedly attractive, pneumatic tools offer a lower total price of ownership and greater throughput over the long term.
Industrial air grinders give you a different value proposition than electric grinders. They are engineered for longevity, efficiency, and above all safety. Air powered grinders are gaining in popularity because of the benefits provided regarding their cost. Adopting air powered grinders ends in greater cost benefits through the entire time of the tool.
On this page, we explore 5 clear cut benefits afforded by the use of industrial grade pneumatic grinders.
1. No recourse of Electric Shock
Grinders of most varieties are often employed in environments where moisture, conductive materials, and flammable liquids can be found. Damaged cords and wires pose a hazard to operator safety caused by electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, for example acetone, to wash and prep metals ahead of welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations could be higher when doing work in confined spaces including those found in the mining and tank cleaning industries. In comparison, air tools require no electricity, in addition to their rotary vane air motors generate no spark. Pneumatic grinders therefore produce a safer workplace which cuts down on odds of generating OSHA violations. The bottomline is, air tools are safer than electric tools because a cloak hose will not emit a spark and is employed in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders give you a better chance to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower in a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools from 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 to the motor isn’t the same wattage that comes to fruition at the spindle with the tool. Actually, only 50% to 60% in the rated wattage actually involves the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will provide 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 can be a priority on your operation (and when isn’t it?), pneumatic grinders will help you meet your goals. When working with grinders of all sorts, Revolutions Each and every minute (RPM) play a critical role from 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 have a speed control mechanism, (also referred to as a governor), that ensures proper RPM by governing the ventilation to the tool. Because operator places downward pressure around the abrasive, the governor “opens up”, increasing air-flow on the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, something Manager for Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and 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 must be respected. Without a periodic rest, the heat generated by the motor itself will diminish performance and finally cause premature tool failure. The truth is, for every 4 minutes running, an electric grinder is designed to have one minute respite.
Furthermore, the generation of particles is built into any material removal process. With all the open grate style motor compartments needed for cooling, electric tool motors tend to be susceptible to the buildup of the dust and dirt. As opposed, Industrial Grade Air Tools are made designed 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 are meant to run 24 hours a day 7 days a week (when used in combination with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not Abs plastic, fiberglass making them more up against the impact from repeated drops. Pneumatic grinders can also be used underwater in the event the exhaust is vented higher than the surface!
5. Ease of Servicing and Sustainability
An advertisement grade grinder is not an disposable machine as well as doesn’t immediately finish up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders can be updated and become periodically rebuilt more often than not over. The common electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at least, a fresh pair of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very industrial grade air grinder can increases to 2000 hours between tune ups. When it’s time to service your air tools, convenient and clearly labeled kits can be obtained that includes the most typical wear parts.
