Removing Chips from a Plastic CNC Router

These CNC routers needed a viable solution to remove and collect plastic chips and debris created during machine operation.

Our distributor in Poland recently emailed me about an application in need of a method to collect plastic chips from the CNC router tables shown above.  These machines are used for precision cutting, but face a problem when the cutting edge of the machine comes into contact with the chips and debris created during normal use.

The end user had considered a blow off device such as a nozzle or Air Knife, but this raised concerns with material collection.  Ideally, the customer wanted to be able to capture the chips and debris for recycling.

So, we looked into a method of removing the chips with a Line Vac, conveying the debris to a stationary drum for collection and recycling.  This type of solution has proven to be effective many times in the past, as shown in the image below. A Line Vac can be mounted at the cutting head to vacuum chips and debris as they are created by the cutting process.

This Line Vac provides vacuum to a drill head to remove debris.

Using the model 6081 Line Vac we can remove the plastic debris from the plotter as it is generated, and convey it to a drum located within the workspace.  And, to facilitate collection of the plastics for recycling, we can use our model 6850 drum cover to separate the conveyed chips from the air used to move the materials.

By providing a dynamic solution for this application, the Line Vac is able to lessen the workload of machine operators, allowing them more time to perform value added tasks rather than cleaning.  And, the solution is easy to install, requires little to no maintenance, and provides instantaneous vacuum only when needed.

If you have a similar application or would like to discuss problems facing your facilities, contact an EXAIR Application Engineer.  We’re available by phone, email, and online chat.

Back At Ya!

This may not be big news as it happens almost every month.  EXAIR is continuing to grow our product line and this time it is something we have never done before.  This new EXAIR Engineered Solution doesn’t blow debris away, instead, it all comes back towards you.   Why would you want this you ask?  What does this new-fangled contraption look like?  Both of those questions will be answered below.

To answer the first question, why would you ever want debris to come back at you?  Well, this isn’t for just blowing any part or area out, this nozzle has been designed for a special purpose – to blow out pipes, tubes, extrusions, and even some blind holes or pockets.   This is ideal when working on a piping system that you may need to clean out and don’t want to push debris further into the system.   It is a quick and easy way to clean out chips from a saw cut operation for tubing or extrusion.  The nozzle could even be used to clean out cylinders or crank shaft openings on engine blocks.

So what is the name of this new nozzle and what does it look like?

What does it look like already!

What does it look like already!

 

The EXAIR Model 1006SS - Back Blow Nozzle

The EXAIR Model 1006SS – Back Blow Nozzle

This is it, the EXAIR model 1006SS Back Blow Nozzle.   The nozzle features a 1/4″ FNPT air inlet, a 3/4″ O.D. to fit into piping, extrusion, or holes, and two flats which allow for the use of a 5/8″ wrench to install the nozzle.   The nozzle is constructed of 316 Stainless Steel, utilizes  22 SCFM when operated at 80 psig, gives off 80 dBA and is designed for use with 7/8″ to 4″ I.D. pipe, tube, or holes.

The unit will also be available on our Safety Air Guns with Chip Shields to offer cleaning excellence and protection for the operators.  Like all of the stock EXAIR products, this is available with our 30 day guarantee.   So if you are not sure whether this nozzle will work on your application, give us a call, get one in, and put it through the paces.   If the Back Blow nozzle doesn’t meet your needs, simply let us know within 30 days from the date of purchase and we will take it back and provide you full credit.

If you want to discuss this nozzle or any other compressed air application, don’t hesitate to contact us.

The Versatile Line Vac

Of all the tools that I own, my cordless drill has to be just about my favorite. I’m remodeling a bathroom in my house right now, and last night I was setting the new toilet flange onto the new tile floor. I had to drill some holes for this through the new tile. I’d never done this before, and was definitely feeling some heartburn about it. Especially after finding out just how fragile and brittle ceramic tile is…I cracked two pieces, just trying to cut a hole for the heat & AC vent register. Luckily, that was BEFORE I mortared & grouted it in, so it wasn’t a big deal…they’re about a buck a piece, and I got five extra anyway.

I know how to do this...but I have no idea how to fix this.

I know how to do this                                                 but I have no idea how to fix this.

THIS one, though, was fully installed, and, despite all the internet videos I found & watched on how to install a tile floor, I haven’t yet had the need to find one that shows me how to replace a broken tile. And I don’t really want to, so I went slowly and carefully with the drill, using the special glass & tile bit that I bought. On my first hole, when I got the bit through the tile itself, I changed to a different (smaller) bit to pilot the screw hole through the subfloor. Then, I put a Phillip’s head bit in to drive the screw. It occurred to me that I was performing these three related but separate tasks, with the same tool…I just thought that was very cool.

Over the course of the last couple of days, I’ve talked to three different callers, with three different Line Vac applications:

HDLV

 

*One wants to use a Model 150200 2” Heavy Duty Line Vac to convey cement. They’re currently hauling the bags, by hand, up to a hopper, where they cut them open and dump them in.

 

Heavy Duty Threaded Line Vac

*One needs to move small springs, one at a time, from a hopper to an automated assembly turret machine.  The springs are 5/8″ in diameter, and they’ll be fed through a length of PVC pipe.  Our Model 151100 1″ NPT Heavy Duty Threaded Line Vac will be easily installed in the pipe line using standard threaded fittings, and the springs will pass through the 0.75″ throat nicely.

*One has a auger-type chip conveyor that removes machining debris from a lathe, and it’s broken…again. They needed a Model 6066 3” Stainless Steel Line Vac, in a hurry, to use until they get their chip conveyor fixed. In fact, if it works, they may not fix the chip conveyor.

 

With a wide range of sizes and materials of construction, we've got your solution.  Call us.

So, kind of like my cordless drill, our Line Vac Air Operated Conveyors have a variety of uses, right out of the box. If you have an application that you think a Line Vac may be able to solve, give me a call.  By the way, if you order one before the end of October, 2014we’ll give you a FREE 2″ Flat Super Air Nozzle.  Really.
