Savvy manufacturers never stop researching ways to website and improve productivity… As the beforehand price of electric power tools is without question attractive, pneumatic tools give you a lower price tag of ownership and greater throughput in the lon run.
Industrial air grinders give a different value proposition than electric grinders. They’re engineered for longevity, efficiency, and more importantly safety. Air powered grinders are becoming more popular as a result of benefits provided with regards to their cost. Adopting air powered grinders results in greater cost savings during the entire time of the tool.
In this post, we explore 5 clear benefits afforded by the use of industrial grade pneumatic grinders.
1. Non-recourse of Electric Shock
Grinders coming from all varieties are generally used 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, for example acetone, to wash and prep metals ahead of welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when working in confined spaces for example those perfectly located at the mining and tank cleaning industries. On the other hand, air tools require no electricity, as well as their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer work environment which decreases the chance of generating OSHA violations. In other words, air tools are safer than electric tools because an aura hose will never emit a spark and can be found in wet conditions.
2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders give a better chance to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower in a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the potency of their tools through the wattage fed inside their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not mentioned in electric tool specifications is the power fed in the motor is not the same wattage that arrives to the spindle from the tool. In fact, only 50% to 60% from the rated wattage actually involves the abrasive or accessory. On the other hand, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will supply that same level of power to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is often a priority for your operation (so when don’t you find it?), pneumatic grinders can help you meet your objectives. Whenever using grinders of any type, Revolutions Per Minute (RPM) play a critical 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 are equipped with a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by governing the air-flow for the tool. Because the operator places downward pressure for the abrasive, the governor “opens up”, increasing air-flow towards the motor and ensuring the proper spindle speed.
4. 100% Duty Cycle + Top rated in Harsh Environments
Mitch Burdick, something Manager for Power Tools 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 possess a rated duty cycle which must be respected. With no periodic rest, the warmth generated through the motor itself will diminish performance and in the end cause premature tool failure. In reality, for every single 4 minutes running, an electric grinder is made 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 necessary for cooling, electric tool motors tend to be vunerable to the buildup of debris and dust. In contrast, Industrial Grade Air Tools are created designed for utilization 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 built to run 24 hours a day 7 days a week (when used with a filter regulator lubricator). Air tool housings are constructed of aluminum or steel, not Fibreglass driving them to more resistant to the impact from repeated drops. Pneumatic grinders could be used underwater if the exhaust is vented across the surface!
5. Easy Servicing and Sustainability
An advert grade grinder isn’t a disposable item of equipment and immediately end up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders might be tuned up and turn into periodically rebuilt more often than not over. The typical electric tool maintenance interval is between 60 and 120 hours after which the tool will typically need, at a minimum, a brand new list of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very industrial grade air grinder can run up to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits can be found that contain the most frequent wear parts.
