A3 41D extraction #thicknesser #planer #A3-41D #dustcollection #hammer

 

Has anyone else noticed that the extraction on this thicknesser is poor? I have it hooked up on a very short run to a portable extractor with 5" hose. The extractor is rated at 2500 m3/h which is well above the 814 required.

If I am machining a wide board (say 300mm / 12") at 1mm the chips build up in the tube quickly. Passes of 2mm make the machine unusable at these widths unless I blow air through the grill from the opposite side towards the extractor. The issue would be much worse at 400mm. ?There are no other machines attached to this extractor so I'm not losing anything there.?

Interested to hear if anyone has noticed this and any possible solutions.?

As I mentioned in my Dylos thread response, I would like my air cleaner to come on automatically when the air quality reaches a certain level.

Anyone aware of a meter that also has an output which I can use to turn on/off my air cleaner. Signal level or drive capability does not matter, I can manage that.

Re: Dylos User Manual

 

Seeing the dylos love here definitely makes it a recommended purchase BUT it doesn't seem like it is designed well for online monitoring without adding additional hackery to data collection, wifi, etc.? Any luck here from the list on something more along those lines?

It is interesting, Jim. Thanks for chiming in!

I thought there must be an assumption about material density baked into the Dylos machine. Maybe Dylos shares that assumption. It does not have to be exact, as wood density varies widely. Fir and pine will run around 33 pounds per cubic foot, while the Jatoba flooring I¡¯m using is about 57 pcf.

The OSHA standards do not take density into account either. Wood dust of all types is lumped together with all other not-otherwise-regulated material.

Greetings all,?

Does anyone know if the "Thick-Box" display for table height can display in Inches instead?

Thanks, Karel

To add to David and Aaron¡¯s advice, keep in mind that, if needed, there should be a 5th support point to counter the weight of the saw aggregate. I am not 100% about K700 but it is present in my KF and K975 saw. This will allow you to remove a dip in cast iron close to the middle of the table. Check you saw parts drawing to locate this bracket. Here is how it appears in my K975 drawing. See label B to visualize where the bracket is attached to the saw chassis. The vertical bolt at the end of the bracket is the persuader. Meant to remove small dips, go easy as it can potentially crack the cast iron.

Thank you David.
Aaron - I don¡¯t have the mobility kit. I installed yesterday levelling feet on the machine.

Re: Upgrading slider

 

Netanel,

I had the same kind of precision level results on my K700S before I adjusted the leveling feet.? I would recommend doing leveling feet first.? This should let you resolve the cast iron twist issue.? I would not start working with the cast iron mounting bolts at this point.? Like David said, the chassis/frame of this machine is flexible enough where it will allow a twist in the cast iron top if the floor is not flat.

-Aaron
Re: Upgrading slider

 

¿ªÔÆÌåÓý

In that case, you should make some adjustments. ?The important thing is that the cast-iron table is as flat flat as possible by getting the edge along the rip fence to be coplanar with the edge along the extension table at the outfeed side of the chassis. ?The cast iron top becomes the reference surface to which you align the sliding table, so if the reference surface is not flat, you¡¯re be chasing your tail when you get to the sliding table alignment.?

The cast top doesn¡¯t have to be level per se, but it does have to be as flat as possible. Cast iron surfaces are easy to twist into the shape of a banana if your machine is not sitting on a flat floor surface (Felder machine chassis are flexible enough to conform to the floor surface). So I always recommend putting the machine on adjustable leveling feet and using those leveling feet to adjust the top to a flat surface.?

Failing that, the cast iron top is suspended at all four corners via adjustable threaded studs and adjusting nuts and jamb nuts which attach it to the machine chassis. You can use those four adjustment points to bring your cast-iron top into a near perfectly flat condition. They are called out in the attached parts diagram, and you will find four (4) such attachment points - one at each corner of the cast iron top. ?Once that¡¯s accomplished, you can move onto aligning the sliding table surface to the cast-iron top surface. Hope this helps.

After reading all the nice comments about the Grit Automation on the previous topic, I wish to take this route with my CF741. However, being a combination machine, I was wondering if anyone had installed Grit with the CF741. For instance, I guess it is easy to detect the the power is on using the toroid on the main power cable, but how do you detect which of the 3 motor is actually on?
You will need to put a current sensing coil on one lead of all of the motors (only three I think).
I saw that Felder resells a device from Ziehl that detects current running through 1-8 machines (link at ) - I guess that this would be useless using Grit automation devices/sensors?
That is an alternative (and possibly cheaper, and less feature rich approach. Still needs the current sensing coils though.
Finally, one last issue, my dust collector is a Harvey GyroAir 700. I usually leave the machine powered on and use the remote to start/stop it. Just powering up the machine won't turn the extractor on, you need to press a button or use the remote. Anyone has used the G700 with some form of automation? The larger models G800 and G1000 can come equipped with automated remote circuit, but they cost a lot more, and are quite a bit larger for my hobby shop. I could have gone with the RL140, but again, over twice the price of the G700. I like the G700, but when I do serious planing, the small capacity and the fact that it stops with an alarm way before it fills up the bags makes me stop working, open the dust container, reshuffle the chips and start again. Lots of handling, but again, just a hobby shop. I can't see any production shop using the G700 except for a table saw or a CNC...
It is best to direct your questions to the GRIT team. From what I have read here they seem to provide excellent support and should be capable of answering your questions most likely.


Kind regards,


Jonathan

Re: Upgrading slider

 

I use the precision machine level and align it on one side of the saw. I moved it to the backend of the cast iron and it show a big difference. I added a filler gauge of 0.25¡± (inch and not mm as described above) to one of the side of the level in order to aligned it.
Re: Upgrading slider

 

¿ªÔÆÌåÓý

Adjusting the cast iron table flatness and the alignment of the sliding table to a flat cast iron table is part of the normal commissioning procedure. ?A Felder tech will align the sliding table to be 0.010¡± (that¡¯s 0.254mm) above the cast iron top as part of the commissioning package. ?But it is certainly possible to dial it in closer. ?Sound like your machine is to Felder spec, but you didn¡¯t comment about how well it stays aligned as it¡¯s moved forward & back. ?

Now I¡¯m confused. ?I¡¯m not saying you are wrong, but unless Felder has modified their measuring tape system, the measurement scale should be movable - if for no other reason than to facilitate shifts left/right to calibrate it accurately to the position of the saw blade cut. ?Typically the measurement scale is anchored into one of the slots in the extrusion with a hex-shaped wafer with a locking grub screw as shown below:

screenshotx_0069.jpeg

You can see this in the end-view of the crosscut fence shown below (red points to locking wafer, green to the movable aluminum strip). ?

screenshotx_0068.jpeg

If you have a telescoping extension, that measurement scale is typically etched into the bar that slides out from inside the extrusion, but it¡¯s a simple matter to paste a different sticky-back tape over the existing version. ? On the rip fence, more typically the aluminum scale strip is held in position by a leaf spring under the rule that pushes it up in the slot against the lip overhangs.

Please take some photos of your fence extrusion and scale from the end position (like above) so we can see how the measurement scale is affixed to the extrusion, and post them here. ?

The strip that move left to right is only on the rip fence. On the crosscut fence it is fixed and it doesn't move.

This is why I think I'll have issues with the calibrate it.

For the crosscut fence I shouldn't get both (R2L for the fence and L2R for the telescopic section)?

So do you the power the grit e-stop from DC current??
Re: GRIT Automation

 

Netanel,

I guess I was not clear in the video.? The transformers are in the machines already.? I am just using existing taps to power the e-stop controllers.? It does not connect to the e-stops.

Re: Dust Collector #dustcollection

 

Imran,?

Your point holds up? if properly sized for the workspace volume and particulate filtration, sure. Bigger cfms and smaller particulate is the goal however it's achieved.

If you are looking primarily for "removing the dust from the air", I would say it depends on which model has the most CFM capability in addition to the most static pressure.? This determines how well it will pull the dust away for things like your CNC machine and wide-belt sander.

Now, "keeping the dust out of the air" is a completely different topic.? If you have asthma or lungs that are sensitive to fine dust, then the baghouse filters are likely going to be poor solutions.? Nedermen doesn't publish what type of bag filters they use, but bags are usually specified at 30 micron or 5 micron.? Typical cartridge filters are around 2 micron.?? The HEPA style filters from Clearvue and Oneida cyclones are in the .2 to .3 micron range.
