Savvy manufacturers never stop researching ways to website and improve productivity… As the up front tariff of electrical power tools is certainly attractive, pneumatic tools give you 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 above all safety. Air powered grinders are gaining in popularity due to benefits provided in relation to their cost. Adopting air powered grinders leads to greater financial savings through the duration of the tool.
In this post, we explore 5 obvious benefits afforded through industrial grade pneumatic grinders.
1. Non recourse of Electric Shock
Grinders of most varieties are likely to be utilized in environments where moisture, conductive materials, and flammable liquids are mixed together. Damaged cords and wires pose a risk to operator safety due to electrical shock. Furthermore, metal fabricators often depend on flammable chemicals, including acetone, to clean and prep metals prior to welding. Pools of spilled liquids can rapidly be ignited by faulty electrical cords. Additionally, vapor concentrations might be higher when in confined spaces for example those found in the mining and tank cleaning industries. On the other hand, air tools require no electricity, along with their rotary vane air motors generate no spark. Pneumatic grinders therefore build a safer work environment which cuts down on likelihood of generating OSHA violations. Simply put, air tools are safer than electric tools because an aura hose will never emit a spark and is utilized in wet conditions.
2. Superior Ergonomics and Power to Weight Ratio
Pneumatic grinders offer a better capability to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower in the smaller and lighter package. Misleadingly, electric tool manufacturers often classify the power of their tools from the wattage fed inside their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not produced in electric tool specifications would be that the power fed into the motor isn’t the same wattage that concerns the spindle of the tool. In fact, only 50% to 60% from the rated wattage actually involves the abrasive or accessory. In comparison, with pneumatic grinders, power in equals power out. An air motor rated for 1 horsepower will offer that same quantity of capability to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside as it were. If increasing worker output is often a priority for the operation (when don’t you find it?), pneumatic grinders can assist you meet your goals. When you use grinders of all sorts, Revolutions Each minute (RPM) play a critical role from the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to execute optimally at the specific RPM. Fortunately, modern pneumatic grinders include a speed control mechanism, (also called a governor), that ensures proper RPM by controlling the venting to the tool. As 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 + High Performance in Harsh Environments
Mitch Burdick, something Manager for Tools at Bosch says: “The two biggest threats affecting electric tool life are dirt and and also heat – 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 has to be respected. Without a periodic rest, the temperature generated by the motor itself will diminish performance and finally cause premature tool failure. In reality, for every single 4 minutes running, a power grinder is designed to get one minute respite.
Furthermore, the generation of particles is built into any material removal process. Together with the open grate style motor compartments needed for cooling, electric tool motors tend to be susceptible to the buildup of debris and dust. In contrast, Industrial Grade Air Tools are created especially 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’re made to run Twenty-four hours a day 7 days a week (when used with a filter regulator lubricator). Air tool housings are constructed with aluminum or steel, not Fibreglass which makes them more up against the impact from repeated drops. Pneumatic grinders can even be used underwater when the exhaust is vented across the surface!
5. Easy Servicing and Sustainability
An industrial grade grinder is not an disposable device and doesn’t immediately result in the landfill being a “disposable” commercial electric grinder. Pneumatic grinders can be updated and become periodically rebuilt more often than not over. The normal electric tool maintenance interval is between 60 and 120 hours and the tool will typically need, at the very least, a brand new list of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a really 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 obtained that contain the most frequent wear parts.
