The EXAIR Chip Trapper™ System Extends Machine Coolant Life

Have you realized that you spend too much time cleaning out your CNC machine?  Do you find that It is messy and backbreaking work?  Do you spend too much money replacing the coolant in your system?  If you answer yes to any of these, EXAIR has a product for you; the Chip Trapper System.

EXAIR created this product to reduce the down time and extend the life of your coolant.  This device will save you money and time with productivity, coolant, and repairs.  In this blog, I will go over some of the features and benefits with the Chip Trapper Systems.

EXAIR offers two types, the Chip Trapper and the High Lift Chip Trapper.  They are designed to move fluid into the drum to be filtered, and to allow the clean fluid to be placed back into the sump.  The Chip Trapper works great for quick coolant cleaning at the floor level.  The High Lift Chip Trapper is ideal for cleaning viscous fluids as well as for reservoirs below the floor level.

Both types use a pneumatic two-way pump to move the fluid.  They come in three different drum sizes, 30 Gallon (114L), 55 Gallon (208L), and 110 Gallon (418L). So, you can clean large sump tanks with only one cycle through the cleaning system.  They come standard with a 5-micron bag filter that can hold over 5 gallons of material.

EXAIR can also offer filter bags in 5 other micron ranges from 1 micron up to 200 micron.  And if you are not sure on the other filtration ranges, EXAIR offers a filter sample pack, model 901060-SP, that includes one of each type.

Chip Trapper Cut Away

The Chip Trapper System includes the drum, the two-way pneumatic pump, a drum dolly, a directional flow valve, 10 feet (3m) of vacuum hose, 20 feet (6m) of compressed air hose, a chip wand, a shut off valve, and two additional filter bags.  All you need to do is to attach the Chip Trapper System to a filtered compressed air source.

The High Lift Chip Trapper offers a more powerful pneumatic pump which can fill a 55 gallon (208L) drum in 85 second from 15 feet (4.5m) below.  And, instead of the 10 feet (3m) vacuum hose, it will come with a  20 feet (6m) vacuum hose.

The unique features with the Chip trappers are the abilities to clean the CNC sump very quickly and with less mess.  Also, by using compressed air to pump the coolant in and out of the drum, it will aerate the coolant.  This will reduce bacteria growth and extend the life of the coolant. Thus, saving you money with those more expensive coolants.

Another benefit is that the pneumatic pump does not have any moving parts to wear out.  So, it will last you a long time without worrying about motor failures or loud noises.

You can watch the video of the operation here:

A list of some benefits that you will see if you purchase the Chip Trapper System is as follows:

  • The number of complete coolant change-outs are reduced.
  • The speed to get the CNC machines back operational to make parts.
  • Reduce the number of barrels of coolant concentrate per year.
  • Bacterial growth dramatically reduced as the Chip Trapper aerates the coolant.
  • Filter bags will remove the chip fines and some tramp oils keeping the coolant fresh.
  • Quiet and long lasting
  • A complete system that is easy to use.

As an added note, some CNC machines come with a spindle coolant feature.  This new technology helps in the need to increase speeds and feed rates.  The coolant is pumped to the top of the machine and fed directly through the spindle.  This type of spindle uses a rotary union which allows the coolant to the spindle as it spins at a high rate of speed.  The rotary unions are very expensive and costly to replace.

These spindles are very susceptible to dirty coolant.  If a seal within the rotary union begins to leak inside the machine, you will not be able to diagnose the problem until they have a machine failure.  The Chip Trapper with help eliminate this chance and keep your machine from an extreme expensive breakdown.

When your machine is not operating, your productivity is lost.  The EXAIR Chip Trapper Systems can be that product for you to get you back up and running is a short period of time, extend your coolant life, and keep the area clean and safe.  A win-win proposition in saving money and time.

For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee to try.  And, for a limited time.  an end-user will get a free EXAIR Vac-u-Gun, a $112.00 value, with any purchase of a Chip Trapper or High Lift Chip Trapper.

Cold Guns for Spot Cooling or Replacing Mist Systems

By using only a source of compressed air, the Cold Gun and High Power Cold Gun produces a stream of clean, cold air 50°F (28°C) below your compressed air supply temperature. The Cold Gun is very quiet at only 70 dBA and has no moving parts to wear out. Just supply it with clean compressed air and it’s maintenance free.

How does it work, and what are the benefits?

  • The Cold Gun uses compressed air to produce a stream of clean, cold air at 50°F (28°C) below supply air temperature. Generally this will be 20°F-30°F outlet temperature.
  • They use Vortex Tube technology…no moving parts to wear out.

How A Vortex Tube WorksInstant cold air flow with no moving parts!

  • Cold flow and temperature are preset to optimize cooling capability, and are non-adjustable to prevent freeze-up during use.
  • Eliminates the expense of both the purchase & disposal of cutting fluids when replacing expensive mist systems.
  • Removes the potential for health problems associated with breathing mist & vapors, and the safety issue of slipping on a wet floor.

Cold Gun Aircoolant System selection is easy & straightforward…we offer a standard, and a High Power version to meet your specific needs.

The Case for the Cold Gun

Heat is an unavoidable by-product of any cutting or machining operation. Think about it: you’re creating friction on a piece of material with a fast-moving piece of harder material in order to forcibly separate pieces of the original material from its existing shape & size. No matter what, something’s going to get hot: the work piece, the tooling, or (almost always) both. If you don’t do something about it, your parts can become damaged, your tooling can become dull and brittle, and productivity will suffer.

There are ways to alleviate the problem…you can slow the speed of your tooling, but that’s hardly practical, and only marginally effective.  You can use liquid cooling…in fact, you may have to if the particulars of the operation require the lubrication you can only get from a cutting oil or liquid coolant.  But those can be messy, expensive, and the time you spend maintaining the coolant could certainly be spent better elsewhere…like, on machining your products!

The EXAIR Cold Gun Aircoolant System is a novel solution to these problems…heat related and otherwise:

  • The Cold Gun uses compressed air to produce a stream of clean, cold air at 50°F (28°C) below supply air temperature.
  • They use Vortex Tube technology…no moving parts to wear out.

We also offer Single & Dual Point Hose Kits, to further meet the needs of your application.  Right now, you don’t have to decide up front…order a Cold Gun Aircoolant System with a Single Point Hose Kit before December 31, 2018, and we’ll throw in the Dual Point Hose Kit for free.

Reversible Drum Vac Empties Sumps For Demolition Company

A demolition company was looking for a way to remove the liquid from sumps and tanks in the industrial buildings they were contracted to provide their service upon. The liquids in question were mainly coolant and oil that had been left behind when the machinery was removed…anything that could be re-used was already gone; this was the “bitter dregs,” as it were.  Since these buildings are about to be demolished, electricity is rarely available.

They had a pumping system that ran off a diesel engine that they COULD take with them, but they ALWAYS had a large mobile air compressor for the pneumatic tools used in other processes in the demolition of the building. Since they had steel drums in abundance, the Reversible Drum Vac Systems sounded very attractive to them, so they got a Model 6295 Deluxe High Lift Reversible Drum Vac System for 55 Gallon Drum to try out.

The High Lift Reversible Drum Vac System converts a drum and dolly into a mobile pumping system.

Now, instead of committing an additional truck (and driver) to getting the diesel engine driven pumping system to the site, they simply move the Reversible Drum Vac pump unit from 55 gallon drum to 55 gallon drum as they’re filled. Once the drums are returned to their facility, they switch the the Reversible Drum Vac to the “empty drum” configuration, and use it to pump the liquid out into their recycling tanks, where they await collection and processing by their waste handling service.  Even when they have to use a number of drums, the High Lift Reversible Drum Vac Systems still streamline the process over the use of the diesel engine pumping system.

E-Vac For Lubricant Recovery

Over the last 3 months, I have been in contact with a customer, keeping track of an application that involved the EXAIR E-Vac.  The customer had reached out to us looking for some advice on how to solve a process problem. The operation is a drawing/stamping process, and the when the part exits the machine there is coolant that resides in a deep draw section, approx 0.4″ in diameter by 3.5″deep.  About 1 oz of coolant per part is retained, and over many 1000’s of parts, would add up to lost dollars and messy clean up.

The customer was looking for an automated process that would be able to draw out the coolant and direct the liquid back to the coolant reservoir, all while maintaining the current machine run rate. We settled in on the model 840015 Adjustable E-Vac Generator. The Adjustable E-Vac has a straight through pathway from suction through to discharge, allowing for fast evacuation times.  A simple turn of the unit changes the vacuum and flow levels to best match the needs of the application.  The Adjustable E-Vac coupled to a solenoid valve controlled by the stamping machine resulted in the automatic system the customer was looking for.

Adjustable EVac
Adjustable E-Vac Family

The customer ordered a unit, and based on the preliminary bench testing, it was approved for a production run trial. After some tweaking in the production environment, the unit was performing to spec, and was then subjected to a 100,000+ part run.  The results were a success!  Instead of the parts exiting onto an inclined conveyor, relying on gravity to drain and causing coolant to collect under the conveyor, the coolant could be removed in a controlled manner and sent back to the reservoir.  Less mess and no coolant loss.

EXAIR manufactures (3) types of E-Vacs – Low vacuum generators for porous materials, high vacuum generators for non-porous materials, and the adjustable type for flexible vacuum performance.  They are available in multiple sizes, to best match the vacuum requirements, while using the least amount of compressed air.

To discuss your application and how the EXAIR E-VAC can benefit your process, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

Celebrating The Chip Trapper

NFL Football season is officially under way, and my hometown team, the Cincinnati Bengals, are off to a solid start. With less than a minute left in the game on Sunday afternoon, an interception stopped the New York Jets’ final drive, and Who-Dey Nation began to celebrate the win. Some (not me…not as far as you know) may have even celebrated in accordance with a hallowed Bengals tradition:

While I won’t celebrate just ANYTHING (although I do indeed hold prompt service at the deli counter in high regard,) you might get me excited enough to do the Ickey Shuffle if you start talking about how much you like your Chip Trapper.  Just like a caller did this morning.

Now, I’m unabashedly proud of all of our products, so I’m not going to come right out and SAY that I have a favorite any more than I would publicly proclaim one of my children as my favorite.  Although, in all fairness, they’re teenage boys, so at any given time, one of them is quite likely edging out the other on The List.

But back to the Chip Trapper – this morning’s caller just wanted to order some more Filter Bags, but in the midst of our conversation, he started “writing the commercial” for the product:

*It’s extended the life of their coolant – regular removal of solids and particulate contamination means the coolant stays clean & effective.

*It ensures the reliability of the machine – clean coolant doesn’t clog the lines, which WILL wreck the part you’re machining, and probably the tooling too.

*It eliminates odors – OK; nobody ever brags about a “spring fresh” aroma in a machine shop, but bacteria-laden, rancid coolant is the WORST.  Nobody needs to be working around that.  And since that bacteria needs solid surfaces to grow on, filtered coolant is fresh coolant.

*It’s EASY (part 1) – it’ll pump 55 gallons of dirty coolant into the drum in about 90 seconds.  Turn the valve and reverse the direction of the Reversible Drum Vac, and it’ll pump freshly filtered coolant back into the sump just as quickly.

*It’s EASY (part 2) – the Filter Bag holds over 5 gallons (almost 3/4 of a cubic foot) of chips, and the system comes with two of them so you can use one while cleaning out the other.

EXAIR's new Chip Trapper
EXAIR’s Chip Trapper comes in 30, 55, or 110 Gallon Sizes, depending on your needs.

If you’ve got a machine shop and DON’T have a Chip Trapper (yet,) call me; let’s talk.  If you DO have a Chip Trapper and you like it as much as my caller today did, DEFINITELY give me a call.  I might even do the Ickey Shuffle with you.

Being a Manufacturer Who Improves Manufacturing Has Benefits – For You

On many of occasions EXAIR has benefitted from our own products. One of the fertile areas for testing, product development, and customer feedback are our own manufacturing and assembly processes. Yes, EXAIR is a real factory in Ohio with employees, machinery, and equipment that uses our products everyday. Being a production facility leaves us best suited to understand the abilities, challenges, and opportunities of our customers. Today, I want to point out how two of our products have helped us to make Intelligent Compressed Air products that exceed your expectations. The Ultrasonic Leak Detector and Chip Trapper have both been studied at our facility to measure and understand the real benefits and capabilities of our products for our customers. Below is their story.

Leak Detector
Ultrasonic Leak Detector, Model 9061

 

Famously, one of the original case studies for our Ultrasonic Leak Detector took place at 11510 Goldcoast Dr Cincinnati, OH. (That’s EXAIR Corporation’s address). As the biggest rival against wasted compressed air, having it at EXAIR would be inconsistent with our own philosophy – we just can’t have it. Our President, Bryan Peters wrote about the benefits of the Ultrasonic Leak Detector in a blog “Free Money!…”. In the blog, he details the mystery of the compressed air costs during times when our plant was not running. Compressed air was so expensive that was costing us money while we were closed. Using the ultrasonic leak detector, EXAIR was able to find our leaks and fix them. The leaks in our system were miniscule compared to some old and very large compressed air systems. But even with our relatively small leaks we were able to save ONE MILLION CF per year of compressed air. This lost compressed air results in significant energy consumption as your compressors try to keep up with the demand caused by the leaky air lines. Please stop wasting money and energy on compressed air leaks. Find them today with EXAIR Ultrasonic Leak Detector.

At EXAIR, we also deal with a  variety of metalworking coolants as we manufacture aluminum, brass, and stainless steel parts. Before we started using our Chip Trapper, our water based coolant would last around 2 months. After those six weeks, we would vacuum out the coolant. After the coolant is pumped out, we would then shovel out the chips that had settled in the bottom of the sump. This task is time consuming, and the smell is awful from the rancid coolant. We found that by using a Chip Trapper weekly. We could extend our coolant life to six months. Some may say that cleaning the coolant sumps weekly is adding work. That is an old mentality though because by removing chips from the coolant weekly we save hours of labor we used to consume every two months and clean up our coolant in minutes not hours.  Here is a video to learn more. Our machinists loved our final prototype so much they kept it. You know how machinists are. Don’t mess with their tools.
