Savvy manufacturers never stop researching to keep costs down and improve productivity… Even though the up front cost of electric power tools is certainly attractive, pneumatic tools provide a lower sum total of ownership and greater throughput over time.
Industrial air grinders give you a completely different value proposition than electric grinders. They’re engineered for longevity, efficiency, and most importantly safety. Air powered grinders are rising in popularity due to the benefits provided in relation to their cost. Adopting air powered grinders brings about greater financial savings through the time of the tool.
In this article, we explore 5 clear benefits afforded using industrial grade pneumatic grinders.
1. Non recourse of Electric Shock
Grinders coming from all varieties are often used in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a danger to operator safety due to electrical shock. Furthermore, metal fabricators often count on flammable chemicals, such as acetone, to completely clean and prep metals just before welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations can be higher when working in confined spaces for example those perfectly located at the mining and tank cleaning industries. As opposed, air tools require no electricity, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer office which cuts down on odds of generating OSHA violations. The bottomline is, air tools are safer than electric tools because a cloak hose will not emit a spark and is employed in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders offer a better capability to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower inside a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the strength of their tools through the wattage fed to their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not stated in electric tool specifications is that the power fed to the motor isn’t same wattage that comes to fruition at the spindle from the tool. The truth is, only 50% to 60% of the rated wattage actually involves the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will provide that very same level of chance to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output can be a priority to your operation (then when isn’t it?), pneumatic grinders will help you meet your objectives. When working with grinders of all sorts, Revolutions Per Minute (RPM) play a crucial role inside 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 come with a speed control mechanism, (also known as a governor), that ensures proper RPM by governing the ventilation for the tool. Because the operator places downward pressure for the abrasive, the governor “opens up”, increasing ventilation for the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + High Performance in Harsh Environments
Mitch Burdick, a Product Manager for Power Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and heat – dropping them in water, or baking them within hot sun doesn’t help either.” By their very nature electric motors have a very rated duty cycle which have to be respected. Without having a periodic rest, heat generated through the motor itself will diminish performance and eventually cause premature tool failure. In reality, for every 4 minutes running, a power grinder is designed to have one minute rest.
Furthermore, the generation of particles is inherent in any material removal process. With all the open grate style motor compartments necessary for cooling, electric tool motors are more vunerable to the buildup of the dust and dirt. In comparison, Industrial Grade Air Tools are made designed for use within foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools use a 100% duty cycle, meaning they are designed to run 24 hours a day Seven days a week (when in combination with a filter regulator lubricator). Air tool housings are constructed of aluminum or steel, not ABS plastic driving them to more up against the impact from repeated drops. Pneumatic grinders can even be used underwater when the exhaust is vented across the surface!
5. Simple Servicing and Sustainability
An industrial grade grinder is not an disposable item of equipment as well as doesn’t immediately result in the landfill as being a “disposable” commercial electric grinder. Pneumatic grinders might be updated and be periodically rebuilt often times over. The average electric tool maintenance interval is between 60 and 120 hours and the tool will typically need, to start, a new group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a very 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 are available which contain the most frequent wear parts.
