Savvy manufacturers never stop looking for ways to keep costs down and improve productivity… Even though the in advance expense of electrical energy tools is without question attractive, pneumatic tools give a lower sum total of ownership and greater throughput over time.
Industrial air grinders offer a totally different value proposition than electric grinders. They’re engineered for longevity, efficiency, and more importantly safety. Air powered grinders are becoming more popular as a result of benefits provided with regards to their cost. Adopting air powered grinders results in greater personal savings through the time of the tool.
In the following paragraphs, we explore 5 obvious benefits afforded using industrial grade pneumatic grinders.
1. Non-recourse of electrical Shock
Grinders of varieties are likely to be employed in environments where moisture, conductive materials, and flammable liquids exist. Damaged cords and wires pose a threat to operator safety due to electrical shock. Furthermore, metal fabricators often rely on flammable chemicals, such as acetone, to scrub and prep metals before welding. Pools of spilled liquids can easily be ignited by faulty electrical cords. Additionally, vapor concentrations may be higher when in confined spaces for example those based in the mining and tank cleaning industries. As opposed, air tools require no electricity, in addition to their rotary vane air motors generate no spark. Pneumatic grinders therefore create a safer work place which lessens the chance of generating OSHA violations. Simply put, air tools are safer than electric tools because a cloak hose will not emit a spark and could be employed in wet conditions.
2. Superior Ergonomics and Capacity to Weight Ratio
Pneumatic grinders offer a better capability to weight ratio than electric grinders. In other words, pneumatic grinders produce more horsepower within a smaller and lighter 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 would be that the power fed in to the motor is not same wattage that comes to fruition at the spindle of the tool. In fact, only 50% to 60% of the rated wattage actually arrives to the abrasive or accessory. In contrast, with pneumatic grinders, power in equals power out. An aura motor rated for 1 horsepower will supply that same amount of power to the tool.
3. Increased Productivity
Let’s put ergonomics and ratios aside for just a moment. If increasing worker output can be a priority for your operation (so when is it not?), pneumatic grinders can assist you meet your primary goal. When you use grinders of any type, Revolutions Each minute (RPM) play a vital role inside 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 are equipped with a speed control mechanism, (also known as a governor), that ensures proper RPM by governing the air-flow towards the tool. As the operator places downward pressure for the abrasive, the governor “opens up”, increasing ventilation towards the motor and ensuring the correct spindle speed.
4. 100% Duty Cycle + High end in Harsh Environments
Mitch Burdick, something Manager for Saws at Bosch says: “The two biggest threats affecting electric tool life are dirt and and warmth – dropping them in water, or baking them with a hot sun doesn’t help either.” By their very nature electric motors have a rated duty cycle which must be respected. With no periodic rest, the temperature generated by the motor itself will diminish performance and ultimately cause premature tool failure. In fact, for each and every 4 minutes running, an electrical 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 required for cooling, electric tool motors tend to be vulnerable to the accumulation of debris and dust. On the other hand, Industrial Grade Air Tools are created specifically 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 meant to run Around the clock Seven days a week (when used in combination with a filter regulator lubricator). Air tool housings are made from aluminum or steel, not ABS plastic causing them to be more up against the impact from repeated drops. Pneumatic grinders can even be used underwater when the exhaust is vented across the surface!
5. Ease of Servicing and Sustainability
An industrial grade grinder is very little disposable item of equipment as well as doesn’t immediately end up in the landfill just like a “disposable” commercial electric grinder. Pneumatic grinders may be updated and become periodically rebuilt many times over. The normal electric tool maintenance interval is between 60 and 120 hours after which it the tool will typically need, to start, a new set 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 contain the most common wear parts.
