Savvy manufacturers never stop looking for ways to website and improve productivity… While the up front tariff of electric power tools is without a doubt attractive, pneumatic tools provide a lower sum total of ownership and greater throughput over time.
Industrial air grinders provide a different value proposition than electric grinders. They are engineered for longevity, efficiency, and even more importantly safety. Air powered grinders are rising in popularity as a result of benefits provided regarding their cost. Adopting air powered grinders results in greater cost benefits through the time of the tool.
In the following paragraphs, we explore 5 clear cut benefits afforded using industrial grade pneumatic grinders.
1. No recourse of Electric Shock
Grinders of most varieties are frequently found 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 completely clean and prep metals just before welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations can be higher when employed in confined spaces such as those found in the mining and tank cleaning industries. On the other hand, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer work environment which cuts down on probability of generating OSHA violations. Simply put, air tools are safer than electric tools because an aura hose won’t ever emit a spark and could be employed in wet conditions.
2. Superior Ergonomics and Chance to Weight Ratio
Pneumatic grinders give a better capacity to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower within a lighter and smaller package. Misleadingly, electric tool manufacturers often classify the effectiveness of their tools by the wattage fed inside their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not produced in electric tool specifications is the power fed in to the motor is not the same wattage that involves the spindle in the tool. In reality, only 50% to 60% in the rated wattage actually concerns the abrasive or accessory. As opposed, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will give that very same volume of power to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is really a priority to your operation (when don’t you think?), pneumatic grinders will help you meet your purpose. When you use grinders of all sorts, Revolutions For each minute (RPM) play an important role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to perform 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 regulating the air-flow towards the tool. Since the operator places downward pressure around the abrasive, the governor “opens up”, increasing air-flow to the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, an item Manager for Power Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and warmth – dropping them in water, or baking them within a hot sun doesn’t help either.” By their very nature electric motors have a rated duty cycle which should be respected. With no periodic rest, heat generated from the motor itself will diminish performance and eventually cause premature tool failure. In reality, for each and every 4 minutes running, a power grinder is designed to have one minute of rest.
Furthermore, the generation of particles is built into any material removal process. Using the open grate style motor compartments essential for cooling, electric tool motors tend to be vunerable to the buildup of the dust and dirt. As opposed, Industrial Grade Air Tools were created designed for used in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning they may be made to run 24 hours a day Seven days a week (when combined with a filter regulator lubricator). Air tool housings are made of aluminum or steel, not Fibreglass driving them to more resistant to the impact from repeated drops. Pneumatic grinders could be used underwater in the event the exhaust is vented across the surface!
5. Easy Servicing and Sustainability
An advertisement grade grinder is very little disposable item of equipment and immediately find themselves in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders could be updated and become periodically rebuilt often times over. The typical electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, at least, a new pair of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a really 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 are available that includes the most typical wear parts.
