How to put a price on productivity?

Price is an important consideration when choosing a tool for metalworking applications, but it alone should not be the deciding factor. Other things also contribute to the total cost of ownership, performance, and, ultimately, the overall productivity.

Ergonomics

One of the key things to look out for is the ergonomics of the tool, specifically the following aspects:  

1/ Power-to-weight ratio

The power-to-weight ratio affects how long an operator can handle the tool over a given period, the speed of material removal, and the operator’s well-being. If you are hesitant between two tools, the power-to-weight ratio is essential to choose the right one for your needs. Chicago Pneumatic’s CP3650 angle grinder, for example, weighs only 1.8 kilos but delivers a power of 1,800W to maximize productivity.

2/Vibrations

Limiting the vibrations that the worker is exposed to when handling the tool is crucial for well-being and productivity. Excessive vibration can lead to hand-arm vibration syndrome (HAVS), which, in the worst case, can result in total loss of sensation in hands, permanently disabling the operator. Selecting tools with features that reduce vibration and stabilize the tool, such as autobalancers, help make it safer to use for extended periods, increasing the material removal rate by up to 15 percent.

The tool’s vibration level and the length of exposure indicate whether an operator will be at risk from HAVS. Vibration and noise can both be minimized by choosing tools with low vibration levels, evaluating the work pattern, and wearing appropriate PPE, such as ear defenders.

Pol Dunoyer, Global Business Development Manager at Chicago Pneumatic

3/Weight

With some tools weighing over five kilos, weight is an important consideration when comparing tools. Can the operator handle the tool for hours at a time? The weigh value can be found in the manufacturer’s catalog, but the operator should always test the tool to ensure its suitability. On paper, weight can be a deceptive value: an ergonomic design can make a heavier tool easy to handle, minimizing the physical strain on the operator.

4/Design

Additional tool’s features and accessories can contribute to the performance and maneuverability of the tool. For example, tools with an ergonomic handle design can reduce vibration, while those with a curved head can deliver better weld bead visibility to optimize precision.

Safety

The right tool can also help reduce the risk of accidents, safeguarding productivity. Many tools from Chicago Pneumatic, for example, feature a two-position safety trigger, which can be adapted to the operator’s grip above or below the housing to reduce the risk of their hands slipping. Governed air grinders, especially when featuring an overspeed shut-off, are also a good way of managing both safety and productivity. They help maintain maximal speed to optimize material removal rates while protecting the operator from the damage caused by abrasive bursts.

Maintenance

As the maintenance cycles and requirements vary between tools, comparison can be challenging. The most important feature to look for is the maintenance interval, which shows how many hours you can use the tool before maintenance is recommended. Knowing and maintaining the maintenance requirements is crucial for ensuring the best performance and preserving the specifications, such as power and speed, that contribute to productivity.

Air compressors come in many types, rotary screw, piston, scroll, reciprocating, some are oil-free and other air compressors require oil lubrication. Like many businesses, an efficient air compressor is at the heart of their operations. So, which type of compressor should you choose? What makes a compressor, like a rotary screw, unique? Here are some clear cut benefits of equipping your business with a rotary screw compressor.  


In the world of compressors, there are often significant and unutilized energy-saving possibilities including energy recovery, pressure reduction, leakage reduction and optimization of operations through correct choice of a control and regulation system as well as the choice of compressor size.We are going to take a look at some of the opportunities for minimizing the compressor’s operating costs. 


Liquid water in compressed-air systems can lead to rusted equipment and unresponsive controls. Anyone who uses compressed air will, at some point, find liquid water in the air distribution system. This can be anything from a nuisance to a serious problem, depending on the application. If water might corrode equipment or introduce bacteria, removing it is critical.

Whenever most people think about a compressor, they probably have a piston compressor in mind. You might already know there are two basic principles of air compression. One of those is the principle of displacement compression. There are a lot of compressor types that classify as a displacement compressor. The piston compressor is one of them, oil-lubricated or oil-free. 


Once you have the size and type of compressor figured out, one last question remains, should I go with an oil lubricated or oil-free air compressor. To not overcomplicate the answer, your choice should be based on the application and process that the compressed air will be utilized in.


Like all compressor types, rotary screw models do require periodic maintenance. Thanks to the simplicity of the internal components, maintenance is relatively easy on most rotary air compressors. As long as you stick to a rotary screw compressor maintenance schedule, you will likely be rewarded with many, many years of optimal productivity from your machine. 


Did you know, the biggest part of the air we breathe is nitrogen? Everyone needs oxygen to survive, however air is made up of 78% nitrogen, only 21% oxygen and tiny amounts of other gases. Although, the human body does not use this nitrogen, it is very helpful in various industrial applications. There is an unlimited source of nitrogen readily available, allowing you to achieve needed purity at a fraction of your current annual nitrogen cost. 


If you notice that your compressor is getting hot and bothered, there may be heating issues affecting your air compressors performance. Did you know that an overheating compressor is top of the pops for being the most common cause of compressor failure. 


A rotary-screw compressor is an air compressor that uses a rotary-type positive-displacement mechanism, typically used replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools. 


Have a look around and what do you see? What are you thinking about? Your next holiday to Queenstown maybe? You might go snowboarding with the kids or have some alone time at the Day Spa. Whatever holiday you choose, compressed air is involved in some way, without you even realising it!  


There are crucial reasons why you should service and maintain your compressor regularly, with the most common issues being piston failure caused by wear of components, increased friction, corrosion, reduced cooling, overheating bearings and components, clogging of air filters. 


Compressed air is all around us, from the air in a balloon to pumping up tires on your bicycle. In this article we will explain what compressed air is and how it is created. Whether you know it or not, compressed air is involved in every aspect of our lives, from the balloons at your birthday party to the air in the tires of our cars and bicycles. It was probably even used when making the phone, tablet or computer you’re viewing this on. 


One of the biggest challenges is to correctly size your new air compressor. Similarly to everything else, new compressors available on the market are more efficient and employ better technology, therefore you have to understand the application and usage to size the machine correctly. Choosing the wrong air compressor for your facility can lead to problems with production and or increased costs due to wasted energy. 


Once you have the size of the air compressor figured out, the next thing to do is to decide on the type of compresor you will need for your application - piston, rotary screw compressor etc. Let us take a look at two of the most popular options available. When choosing the right type of compressor, you should ask yourself the following questions:


​Which vacuum pump do I need? - this is one of the most frequent questions we receive and this is understandable, because there are number of technologies which can provide the same vacuum level and pumping speed. Here is quick advice on how to choose the best vacuum pump for your needs. 


You may be asking, why does my air compressor start, then stop? Allow us to take the guessing out of it. We understand your pain. We know that a compressor problem can quickly result in hours (if not days) of production downtime and loss of revenue. When your compressor continuously shuts off from on, we refer that as a short cycle. There are a few reasons that a short cycle may be happening with your compressor. 


Air compressor leaks are very common in all applications, but can be very costly and difficult to find. On average, 20-30% of the compressed air used in a manufacturing plant is wasted as leaked air. Finding and fixing these leaks can save your business thousands of wasted dollars a year. 


When installing a compressed air system into a business, people often look to PVC piping as an option to build a piping system because it is cheap, versatile and easy to install. However, using PVC pipe in any compressed air application is extremely dangerous and NOT recommended by multiple associations and manufacturers. 


Changing the oil and oil filters on your compressor is one of the most common routine maintenance tasks to perform to keep your compressor running efficiently. After you remove your old oil and oil filter, you may find yourself wondering, “Where do I dispose of these?”, or “Can I just throw them in the trash?”. Because oil is toxic and a pollutant, disposing of your old oil and filters is not as simple as just tossing them in the trash.Â
