Thread: laser cut mild steel
24/06/2019 12:27:21

The laser will heat the metal around the cut to above its transformation point and this will create a Heat-affected Zone. The HAZ for laser cutting is quite small and localised near the cutting point. For CO2 lasers Oxygen is mainly used for cutting mild steel but Nitrogen can also be used for high pressure cutting. Nitrogen mainly used for high pressure cutting Aluminium and Stainless Steel. At least that's how we do it.

Nice work Jim. How did you make the connecting rods?

New table drive motor fitted. Had to alter the length of the existing opinion, make an extension shaft and fit an extra bearing inside the mounting plate to get it to fit correctly. It took a bit of time but works well now.

I picked up a 24v dc led lamp from eBay to give it a try as a machine light and it works well. Fitted a couple of pipe holders to the side of the mill column. An insert was glued into the bit of stainless steel pipe to drill and tap for the lamp bracket and the tube was slotted so that the cable could be run through it.

I may get another lamp for the other side but will see how it goes when I get started making some bits on the machine. Just got the coolant to sort out now and it should be all done.

Welcome to the forums. I'm not far away near Falkirk.

Great video. Loved the bit with the lamp going on above the box to show what part went where.

Did a bit more cutting tonight with one of the horizontal cutters picked up from eBay. Definitely happy with the cut quality so far.

Now I need to get on with sorting out the table drive.

Thanks for the compliments guys. It has been a nice project to do. Decided last night that I couldnt wait any longer and stuck a bit of sqaure steel bar in the vice and had a go with the horizontal cutter. So far I`m well impressed. Nice cut with a used cutter I picked up from ebay. Started making some T nuts for the table.

Thanks guys. I have a couple of ballscrews somewhere so that might be a job for the future. I will look into the larger handle idea.

Had a busy weekend and now have the mill running on both vertical head and horizontal. Bearings sound good under power apart from a bit of a rumble from the intermediate pulley on the vertical head but that's an easy fix.

The motor has arrived for the table drive and I need to make a new adapter plate for it and an extension shaft so it fits in the gearbox properly. First job though is to make some t-nuts for the table.

I've just burnt out my cordless Bosch drill as well, must be the week for it. But I'm going to quite happily buy another as the batteries and charger are good and also it has lasted me for quite a few years of hard work.

It's for holding straight shank drill in a taper socket. Does it not lock onto the drill when gently tapped into the MT socket?

Total stupidity. They've destroyed a lifetime of work and will get a slap on the wrist.

The mill has mostly been reassembled now, just a couple of covers to finish off.

Now its time to get started on the electrics and sort out the new motor for the table drive.

Second attempt at this post. VM are apparently having issues which are intermittently shutting down the Internet connection. Keyway cutting went rather well with the home made tool.

Horizontal motor has been fitted. Bit of a pain fitting it in on my own. Had to put the motor in and prop it up on some wood then bolt on the fitting plate inside the base.

I have the inverter and enclosure I used on my old cnc mill so I intend to use it for this mill. The inverter will used for the table drive and I should be able to crowbar in the psu, contactors and overloads for the drives.

Also have a spare box the same as I used for my lathe so going the same way for the mill.

Table has been put back on the knee but gibs are not fitted yet. There is quite a bit of backlash in the long travel screw but that will be a job for later. Both vertical and horizontal motors have arrived. Vertical motor has been fitted via an adapter plate to measure the length of drive belt I need then removed to get the adapter plate painted. The new motors have 24mm diameter shafts and I have bored out the vertical one to fit the shaft but I don't have an 8mm keyway breach so thinking about making a boring bar type one and either cutting the keyway on the lathe or on the mill.

Knee refitted today but I need to get another screw to replace the snapped one so that's tomorrows job. Also found the over arm support lock in the box of bits.

The rest of the parts on the head have been painted and fitted as well. Gear box cover replaced and oil changed.

Started cleaning up the table now.

I gave them a clean down with grease cleaning wipes. Any remaining stubborn bits got a gentle rub down with wd 40 soaked scotch bright pads.

11/05/2019 20:36:32

Managed to get some more cleaning and painting done.

Snapped grub screw in the knee gib adjuster but thankfully it wasn't stripped or jammed so came out easily with a small point punch.

Also managed to clean up the aluminium pulleys but found a crack in one and had to remove a small part of the pulley but I don't think it will cause any issues.

Ive decided not to go with inverter drives for the horizontal or vertical so both motors have been ordered and should arrive mid week. I have a 400 Watt servo and amplifier so Im thinking about using it for the table drive. Still cant find any info on the net about the original drive motor fitted to it.

Philip, the yahoo group seems to be dead now. I tried to join and sent the required emails but haven't received any replies.

Does anyone have a photo of the tally plate on the omnimill table drive motor, the original one? The plate is missing from mine and I would like to have the info on it if anyone can help.
