Vertical Mill Tutorial 4 : Basic Milling Operations

[@bobaloo2012]

Excellent video. One of my most common uses for a center cutting endmill is when I have to drill a hole on an angled surface. Plunge the endmill to cut a flat spot, then drill.

[@Blondihacks]

Yes, totally! I should have called that out.

[@steveclark..]

I were told that the four flute end mills were better for drilling holes especially in those situations. I dunno, I could only afford to buy one set of end mills at the time.

[@jordanhartmann1745]

Your videos have to be the best explained thing I've maybe ever watched. You go into just enough deep detail without making it too slow, just enough humor without being obnoxious. Just absolutely so well done. I just got my first mini mill, thanks for the great tutorials.

[@walterjoncas12]

You are a master at inserting well time bits of levity. This can only be pulled off successfully when the teacher knows and understands the subject matter. Well done. Excellent video too.

[@Blondihacks]

Thank you very much! ☺️ I really appreciate that.

[@lyndone.2682]

You've explained climb vs. conventional milling better than just about anyone! Very articulate! Outstanding Video!

Excellent video. I was in the tool and die trade and you have my respect. When climb milling in the Bridgeport without a power table feed, I always snug up on the table lock just enough to prevent shudder from leadscrew backlash as I carefully crank away.

[@garyhardman8369]

I don't have a milling machine - just a small 'Z' slide that attaches to my lathe tool post. Always struggled with the concepts of conventional versus climb milling. Thanks to your excellent video, I now understand them properly. Thank you Quinn.

[@ninthm00n]

Always a treat to watch another Blondihacks video . Thanks Quinn

[@bostedtap8399]

Love the screen image inset, very clever 😜. Excellent treatise on standard milling, centre cutting cutters do have aysmetric flats, used for pocketing. A trick to use climb milling (side cutting), on all manual machines, is to apply pressure on the relevant traverse axis lock, ie, try to prevent the table or slide being pulled by the cutting action, bigger milling machines have "Climb Milling" settings, normally a lever on the X axis. Do not use this technique when power feeding, or you will burn out your feed motor. You also experience climb milling when cutting a slot, especially on grabby materials/sharp cutters. The reason for problems on climb milling is that axis have a standard leadscrew on nut, these have backlash!, Where CNC machines have both ballscrews and servo motors that have zero backlash, and position control. Again, great milling knowledge Quinn, and best regards from the UK.

[@Mars5826]

[@charliemacrae1045]

I really enjoy your videos. You are a great teacher and I love you humor. Thank you.

[@richards6452]

Excellent video . May I just point out an aspect of climb milling that is significant. Climb milling has the tendency to accelerate the work piece in the direction of the leadscrew backlash! If this happens the table jolts forward to accomodate the backlash and as you mentioned the deep initial engagement of the cutter remain deep to the end of the cut. This applies a horizontal force to the cutter and at times may break the tool. This phenonemon raises its ugly head when there is excessive backlash in the lead screw. It can be avoided by having expensive, but desirable ball screws or applying some drag, using the appropriate table lock to resist the forward inpulse imparted by the cutter. Keep up the GREAT work, Richard

[@danedewaard8215]

Great video! Marvelously explained and demonstrated!!!!

[@hairyfro]

Nice video once again. It's really useful to see all this information presented coherently in one place.

[@davecook5068]

Hi Quinn , I just started watching your videos tonite starting with the lathes and now the mills. You have a unique method of teaching that covers all the bases extremely well . I started building target rifles and have had to send all of my machine work off to be done because I don't have the lathe or mill . And truthfully don't know how to operate these machines , BUT after going to your school of knowledge on setting them up I intend to start shopping for some . Can't wait to view more of your videos , keep up the good work !!! Dave Cook

[@victorldunn9638]

Very informative - thank you. I was using a router to put a curved edge on some timber yesterday where the results were better when the mill was climb cutting, and gave a rougher finish when going in the other “conventional” direction. 😊 Great to get this so clearly explained when I then later watched your video.

I have since ordered two solid shell mills. One HSS and other M42 cobalt w/o jelly thank you. Cheers!

Your mill/lathe skills videos are great, especially for people just getting started. I plan on adding a small manual mill within the next year, mainly to face off pieces (or otherwise pre-process) to use on my CNC. To get around not having a mill I've been using a lot of ATP/MIC6 but there are so many good uses for a manual mill that it's inevitable that I will get one.

@@marcmckenzie5110 You said it! They are incredibly useful tools, but two of my three closest calls with power tools were both with a plunge router.

[@MaxWattage]

Well, I learned something new! I hadn't previously appreciated that end-mills had a cone-angle, so that when touching-off the tool-height and then plunge milling by a given amount, the resulting hole isn't going to have the expected depth, or even a flat bottom. That's certainly going to complicate making genuinely flat-bottom holes with a manual machine that can't (easily) do interpolation milling of holes with a smaller end-mill than the hole diameter (I could use a rotary table to do this I suppose.). To achieve this with a boring head for small holes (< 1/2"), I would need either buy a (probably very expensive) miniature boring tool, or very carefully grind and harden my own.

[@michaeljohnson-li5nn]

Quinn, many years ago when I was serving my apprenticeship, the college lecturer always referred to conventional milling as ‘upcut’ milling. Not sure where this terminology originated from but I did come across it again when I first stated learning off-line CNC programming. The system was called GNC (graphic numerical control) this system was pretty much state of the art in the early eighties. To control the direction of the cutter on the display screen you could select the climb or upcut option. In conjunction with other commands the operator could control the direction the milling cutter took on the periphery of a part, thus giving conventional or climb milling. The GNC program required post-processing in order to produce the G & M codes to load to the CNC controller.

[@Blondihacks]

Interesting! I can see “upcut” as a good name if you look at how the tooth enters the material from below in that direction.

[@robertoswalt319]

Great video Quinn.

[@NialPowerCork]

Superb video, thank you.

[@henrydando]

Another note on climb vs conventional milling. climb milling will also push on your lead screw and mill will easily able to move the backslash of your lead screw. Our hobby machines or older machines use ACME/trapezoidal lead screw which have a fair bit of backlash compared to modern CNC machines which use ballscrews with very very little backlash. not sure if the backlash problem or rigidity problem are worse but thats why your still use conventional milling on a Bridgeport

[@SweetTooth8989]

Love this. Your videos are helping me quite a bit. Been into metal working for a few years but only recently got into milling. Bought myself one of those small mills and I love it so much. Your videos are really helping me learn. Only one thing that is concerning me, maybe somebody can chime in. One of the first things I did when I got my mill cleaned and set up was to run a test indicator across the table in the x and y. Left to right I am getting a difference of around 6 thou, and back to front almost 5. Is this normal for these small mills? I know they're entry-level mills but doesn't that seem like quite a bit? I milled a 2 inch cube as a test and just in those 2 inch faces I'm getting a few thou of unevenness... Is there anything I can do about this? As far as I am aware there's no way to adjust the table? Maybe I should disassemble the table and clean under it but would that change anything? I only bought the mill less than a month ago so if anybody can let me know if this is something I should be concerned about or if I should go back to the store? To be honest I haven't been doing as much milling as I would have liked since I got it because I can't seem to get parts that come out flat when I run an indicator across them.

[@Blondihacks]

Great question! First, yes, that is way too much variation. Second, you can fix it by adjusting the head. If there’s a tilt or nod adjustment, use that to tram it in. If not, you can put shims under the mounting bolts on the head or the column (whichever is easier). Shimming the head or column will cost you some rigidity, but it’s worth it if the tram is out by that much. Get yourself one of those variety packs of precision shim stock and it will have everything you need.

[@SweetTooth8989]

@@Blondihacks thanks alot for the response. I probably should have checked the adjustment on the head to see but for some reason I just assumed it was ok because the pointer was in line with the zero degree mark. I guess it would not be really noticeable by eye though. I'm really clueless when it comes to machining so I've just been watching KZbin videos to learn. I'm going to try adjusting the head to see if that can reduce the variation and if not I will look into getting some shims like you mentioned. Thanks.

[@SweetTooth8989]

After tramming the mill, I was able to get it under half a thou from left to right and zero thou front to back. I'm really happy with that. Thanks for the help. Also readjusted all the gibs.

[@charlescamen5225]

Hi Quinn, it may be helpful; to consider the backlash in the table when discussing the benefits of conventional milling versus climb milling. In conventional milling the thrust of the cutter is pushing against the drive screw and so backlash is kept under tight control and so is not a problem. While climb milling the cutter is pulling away from the drive screw, that is moving the table forward, so a relatively light weight table may slap backwards and forward, between the limits of the table backlash, as the cutter cuts and releases as it turns. This is what I believe, causes the higher levels of vibration on light weight tables with loose dovetails. a more in-depth video on this aspect may well be of benefit to your viewers.

[@paulmorrey733]

Thanks Quinn

[@anthonykinrade8642]

Great tuition.....❤

[@scollyer.tuition]

This is a fine series. Chapeau. One question though: you mentioned drilling most of a flat bottomed hole, then using a milling bit to finish. However, does that mean that you have to move the workpiece to a drill, or are standard drill bits available for mills, so that the whole job can be done on one machine? Also, when using a mill to make a slot in the middle of thin metal stock, is it necessary to drill a starter hole first, or can you get away with the appropriate milling bit to cut the initial hole, and the slot too?

[@LeicaCat]

Thank you.

[@brucelindsey3432]

Thanks for the great info. Can’t find the link for the shell mill.

[@MaxWattage]

One problem on manual machines that use ACME thread lead-screws (rather than CNC machines that use anti-backlash ball-screws) is that with climb-milling, the workpiece is not constrained properly due to the backlash in the lead-screw. The end-mill can therefore suddenly grab workpiece and pull it and the whole table towards itself by the distance of the backlash. This can lead to the workpiece being fired across the room (if it isn't clamped down very securely), scraping of the part, or cause tool breakage. (I'm perfectly sure that Quinn knows all this, but I don't think the ACME-threads being the cause of the problem was spelled out in this video.) This other video illustrates what can go wrong kzbin.info/www/bejne/nZLPnmiVa7iIma8

[@Blondihacks]

Yes, it would have been good to mention the differences in leadscrews and how that affects climb milling.
