Savvy manufacturers never stop researching to website and improve productivity… Even though the in advance price of electricity tools is undoubtedly attractive, pneumatic tools offer a lower total cost of ownership and greater throughput over the long term.
Industrial air grinders give a very different value proposition than electric grinders. They may be engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are rising in popularity because of the benefits provided in relation to their cost. Adopting air powered grinders brings about greater cost savings through the lifetime of the tool.
In this article, we explore 5 clear benefits afforded by way of industrial grade pneumatic grinders.
1. Non recourse of Electric Shock
Grinders of all varieties are frequently utilized in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a hazard to operator safety resulting from electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, for example acetone, to completely clean and prep metals ahead of 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 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 office which decreases the probability of generating OSHA violations. The bottomline is, air tools are safer than electric tools because an air hose will not emit a spark and could be utilized in wet conditions.
2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower in a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the power 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 is the power fed in the motor isn’t same wattage that comes to fruition at the spindle from the tool. In fact, 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 aura motor rated for 1 horsepower will supply that very same volume of chance to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside as it were. If increasing worker output can be a priority to your operation (and when don’t you find it?), pneumatic grinders will help you meet your objectives. When you use grinders of all sorts, Revolutions Per 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 with a specific RPM. Fortunately, modern pneumatic grinders come with a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by money air-flow towards the tool. Since the operator places downward pressure around the abrasive, the governor “opens up”, increasing ventilation towards the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, a product or service 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 under a hot sun doesn’t help either.” By their very nature electric motors have a very rated duty cycle which must be respected. Without having a periodic rest, the heat generated with the motor itself will diminish performance and eventually cause premature tool failure. In fact, for every 4 minutes running, an electrical grinder was created to have one minute respite.
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 tend to be vunerable to the accumulation of the dust and dirt. In contrast, Industrial Grade Air Tools are designed particularly for utilization in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools use a 100% duty cycle, meaning these are designed to run 24 hours a day 7 days a week (when used with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not ABS plastic making them more resistant to the impact from repeated drops. Pneumatic grinders could even be used underwater if your exhaust is vented higher than the surface!
5. Ease of Servicing and Sustainability
A commercial grade grinder is not a disposable machine and doesn’t immediately find themselves in the landfill as being a “disposable” commercial electric grinder. Pneumatic grinders can be tuned up and be periodically rebuilt often over. The common electric tool maintenance interval is between 60 and 120 hours and the tool will typically need, at the very least, a 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 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 common wear parts.
