Savvy manufacturers never stop researching ways to keep your charges down and improve productivity… While the in advance tariff of electricity tools is without a doubt attractive, pneumatic tools give a lower total cost of ownership and greater throughput over time.
Industrial air grinders provide a completely different value proposition than electric grinders. These are engineered for longevity, efficiency, and most importantly safety. Air powered grinders are gaining in popularity due to benefits provided with regards to their cost. Adopting air powered grinders results in greater cost savings during the entire duration of the tool.
In this article, we explore 5 obvious benefits afforded by way of industrial grade pneumatic grinders.
1. No Risk of Electric Shock
Grinders of varieties are likely to be employed in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a danger to operator safety resulting from electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, such as 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 in confined spaces such as those located in the mining and tank cleaning industries. On the other hand, air tools require no electricity, in addition to their rotary vane air motors generate no spark. Pneumatic grinders therefore develop a safer work place which lessens the chance of generating OSHA violations. In other words, air tools are safer than electric tools because a cloak hose will never emit a spark and could be utilized in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders provide a better power to weight ratio than electric grinders. To put it simply, pneumatic grinders produce more horsepower in the smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools by the wattage fed inside their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not stated in electric tool specifications is the power fed into the motor isn’t same wattage that concerns the spindle in the tool. In fact, only 50% to 60% with the rated wattage actually comes to fruition at the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An air 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 really a priority on your operation (so when isn’t it?), pneumatic grinders will help you meet your objectives. When working with grinders regardless of the sort, Revolutions Per Minute (RPM) play a vital 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 are equipped with a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by money air-flow to the tool. Since the operator places downward pressure for the abrasive, the governor “opens up”, increasing venting for the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + High end 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 rated duty cycle which must be respected. With out a periodic rest, the warmth generated by the motor itself will diminish performance and ultimately cause premature tool failure. In fact, for each 4 minutes running, an electric powered grinder was created to get one minute rest.
Furthermore, the generation of particles is inherent in any material removal process. Using the open grate style motor compartments required for cooling, electric tool motors will be more susceptible to the buildup of dust and debris. In contrast, Industrial Grade Air Tools are made specifically for use in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning these are built to run Round the clock Seven days a week (when in combination with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not ABS plastic which makes them more up against the impact from repeated drops. Pneumatic grinders could be used underwater when the exhaust is vented over the surface!
5. Simple Servicing and Sustainability
An advertisement grade grinder is not an disposable piece of equipment and doesn’t immediately finish up in the landfill like a “disposable” commercial electric grinder. Pneumatic grinders might be updated and be periodically rebuilt more often than not over. The typical electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, to start, a brand new group 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 it’s time to service your air tools, convenient and clearly labeled kits can be found that contain the commonest wear parts.
