5 Top Features Of Using Air Powered Grinders Instead Of Electric
Savvy manufacturers never stop searching for ways to reduce costs and improve productivity… While the beforehand expense of electric power tools is without a doubt attractive, pneumatic tools offer a lower total price of ownership and greater throughput over time.
Industrial air grinders offer a totally different value proposition than electric grinders. These are engineered for longevity, efficiency, and most importantly safety. Air powered grinders are increasing in popularity as a result of benefits provided in relation to their cost. Adopting air powered grinders leads to greater cost savings through the entire duration of the tool.
On this page, we explore 5 clear cut benefits afforded by the use of industrial grade pneumatic grinders.
1. Non recourse of Electric Shock
Grinders of varieties are often found in environments where moisture, conductive materials, and flammable liquids are present. Damaged cords and wires pose a risk to operator safety as a result of electrical shock. Furthermore, metal fabricators often depend on flammable chemicals, such as acetone, to scrub and prep metals ahead of welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when in confined spaces for example those located in the mining and tank cleaning industries. In contrast, air tools require no electricity, and their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer work environment which lessens the likelihood of generating OSHA violations. Simply put, 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 Capacity to Weight Ratio
Pneumatic grinders give you a better power to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower in the lighter and smaller package. Misleadingly, electric tool manufacturers often classify the strength 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 would be that the power fed into the motor isn’t the same wattage that arrives to the spindle with the tool. Actually, only 50% to 60% with the rated wattage actually comes to fruition at the abrasive or accessory. In comparison, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will supply that same amount of chance to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside if you’ll. If increasing worker output is a priority to your operation (and when isn’t it?), pneumatic grinders will help you meet your purpose. When you use grinders of any type, Revolutions Each minute (RPM) play a critical role in the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to perform optimally with a specific RPM. Fortunately, modern pneumatic grinders are equipped with a speed control mechanism, (also known as a governor), that ensures proper RPM by regulating the venting for the tool. As the operator places downward pressure about the abrasive, the governor “opens up”, increasing air flow on the motor and ensuring the best spindle speed.
4. 100% Duty Cycle + Top rated in Harsh Environments
Mitch Burdick, something Manager for Saws at Bosch says: “The two biggest threats affecting electric tool life are dirt and and also heat – dropping them in water, or baking them under a hot sun doesn’t help either.” By their very nature electric motors possess a rated duty cycle which must be respected. Without having a periodic rest, the warmth generated from the motor itself will diminish performance and eventually cause premature tool failure. In reality, for each 4 minutes running, a power grinder is made to get one minute rest.
Furthermore, the generation of particles is inherent in any material removal process. Together with the open grate style motor compartments required for cooling, electric tool motors tend to be more prone to the accumulation of debris and dust. As opposed, Industrial Grade Air Tools were created particularly for use 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 made to run Round the clock 7 days a week (when combined with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not ABS plastic driving them to more up against the impact from repeated drops. Pneumatic grinders could be used underwater in the event the exhaust is vented above the surface!
5. Simplicity of Servicing and Sustainability
A commercial grade grinder is not an disposable piece of equipment and does not immediately finish up in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders may be updated and stay periodically rebuilt often times over. The common electric tool maintenance interval is between 60 and 120 hours after which the tool will typically need, at least, a whole new list of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a truly industrial grade air grinder can increases to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits can be purchased that contain the most frequent wear parts.
