Savvy manufacturers never stop searching for ways to website and improve productivity… As the at the start price of electricity tools is without question attractive, pneumatic tools offer a lower total cost of ownership and greater throughput in the lon run.
Industrial air grinders offer a completely different value proposition than electric grinders. They are engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are gaining in popularity as a result of benefits provided in terms of their cost. Adopting air powered grinders brings about greater financial savings during the entire life of the tool.
In this article, we explore 5 obvious benefits afforded using industrial grade pneumatic grinders.
1. No recourse of electrical Shock
Grinders of most varieties are likely to be used 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 depend upon flammable chemicals, like acetone, to clean and prep metals before welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when doing work in confined spaces like those perfectly located at the mining and tank cleaning industries. In contrast, air tools require no electricity, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer work environment which cuts down on likelihood of generating OSHA violations. Simply put, air tools are safer than electric tools because a cloak hose will never emit a spark and can be used in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders give a better capacity to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower in the lighter and smaller package. Misleadingly, electric tool manufacturers often classify the power 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 would be that the power fed in to the motor isn’t same wattage that comes to fruition at the spindle in the tool. In fact, only 50% to 60% in the rated wattage actually concerns the abrasive or accessory. In comparison, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will give that same amount of capacity to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for just a moment. If increasing worker output is often a priority for your operation (when don’t you think?), pneumatic grinders can assist you meet your purpose. When making use of grinders of any type, 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 do optimally at a specific RPM. Fortunately, modern pneumatic grinders include a speed control mechanism, (also known as a governor), that ensures proper RPM by governing the venting to the tool. Because operator places downward pressure around the abrasive, the governor “opens up”, increasing air flow for the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + Top rated in Harsh Environments
Mitch Burdick, something Manager for Saws at Bosch says: “The two biggest threats affecting electric tool life are dirt and and also heat – dropping them in water, or baking them within hot sun doesn’t help either.” By their very nature electric motors use a rated duty cycle which have to be respected. With out a periodic rest, heat generated from the motor itself will diminish performance and in the end cause premature tool failure. The truth is, for each 4 minutes running, a power grinder is made to get one minute rest.
Furthermore, the generation of particles is inherent in any material removal process. With all the open grate style motor compartments required for cooling, electric tool motors are more prone to the accumulation of dust and debris. As opposed, Industrial Grade Air Tools were created particularly for utilization in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a very 100% duty cycle, meaning they are designed to run 24 hours a day 7 days a week (when used in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not Abs plastic, fiberglass making them more up against the impact from repeated drops. Pneumatic grinders can also be used underwater when the exhaust is vented across the surface!
5. Simplicity of Servicing and Sustainability
An advert grade grinder isn’t a disposable item of equipment and does not immediately finish up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders might be tuned up and stay 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 set of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a totally 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 most typical wear parts.
