Savvy manufacturers never stop looking for ways to website and improve productivity… While the at the start price of electrical power tools is undoubtedly attractive, pneumatic tools give you a lower total price of ownership and greater throughput in the lon run.
Industrial air grinders give a different value proposition than electric grinders. They may be 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 leads to greater cost savings throughout the duration of the tool.
In the following paragraphs, we explore 5 clear benefits afforded through industrial grade pneumatic grinders.
1. No recourse of Electric Shock
Grinders coming from all varieties are likely to be found 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 depend upon flammable chemicals, for example acetone, to clean and prep metals before welding. Pools of spilled liquids can quickly be ignited by faulty electrical cords. Additionally, vapor concentrations can be higher when in confined spaces such as those found in 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 build a safer work place which cuts down the odds of generating OSHA violations. In other words, air tools are safer than electric tools because an air hose won’t emit a spark and could be used in wet conditions.
2. Superior Ergonomics and Capability to Weight Ratio
Pneumatic grinders provide a better capability to weight ratio than electric grinders. The bottomline is, pneumatic grinders produce more horsepower within a smaller and lighter package. Misleadingly, electric tool manufacturers often classify the potency of their tools by the wattage fed within their electric motors (incidentally 750 watts equals roughly 1 horsepower). What’s not stated in electric tool specifications could be that the power fed into the motor is not same wattage that involves the spindle in the tool. In reality, only 50% to 60% of the rated wattage actually arrives to the abrasive or accessory. In comparison, with pneumatic grinders, power in equals power out. A cloak motor rated for 1 horsepower will offer that same volume of capability to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for a moment. If increasing worker output is often a priority for the operation (so when don’t you think?), pneumatic grinders can help you meet your objectives. When you use grinders of any type, Revolutions For each minute (RPM) play a vital role from the material removal equation. Abrasive products (grinding wheels, fiber discs, flap wheels, etc.) are engineered to complete optimally in a specific RPM. Fortunately, modern pneumatic grinders come with a speed control mechanism, (otherwise known as a governor), that ensures proper RPM by regulating the air flow on the tool. Because operator places downward pressure for the abrasive, the governor “opens up”, increasing air flow towards the motor and ensuring the right spindle speed.
4. 100% Duty Cycle + Powerful in Harsh Environments
Mitch Burdick, a product or service 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 have a rated duty cycle which should be respected. With no periodic rest, the warmth generated from the motor itself will diminish performance and ultimately cause premature tool failure. Actually, for every single 4 minutes running, an electric powered grinder is made to get one minute of 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 vunerable to the accumulation of dust and debris. In comparison, Industrial Grade Air Tools were created designed for utilization in foundries, shipyards, offshore oil platforms, power plants, metal fabrication facilities, and petrochemical refining plants. Air tools have a 100% duty cycle, meaning they are designed to run 24 hours a day Seven days a week (when used with a filter regulator lubricator). Air tool housings are constructed of aluminum or steel, not Abs plastic, fiberglass which makes them more up against the impact from repeated drops. Pneumatic grinders could be used underwater in the event the exhaust is vented over the surface!
5. Simplicity of Servicing and Sustainability
A commercial grade grinder is not an disposable device and doesn’t immediately finish up in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders can be tuned up and be periodically rebuilt many times over. The average electric tool maintenance interval is between 60 and 120 hours then the tool will typically need, at a minimum, a new group of brushes. Comparatively, a garage / maintenance grade air tool averages 200 hours between service intervals while a really industrial grade air grinder can amass to 2000 hours between tune ups. When the time comes to service your air tools, convenient and clearly labeled kits can be obtained which contain the most typical wear parts.
