    Wow ! never seen one of these machine before ! GREAT machine , I HATE press brooches with shims !

    machines like this and shapers are mind boggling to me - that someone thought of it and built it. The accuracy they have for mid 19th century technology built in mid 20th century. really cool.

    much easier than pressing a broach through the hole, no shims and no guide plug to make or buy. I get to use a similar machine today or if I have time, clean up the shaper and cut it on that.
    Old technology will always be needed. : )

      I just saw the video where Adam purchased one.
      Its a good machine. We have broached several dozen key ways on it. I even used it to scrape in a repair I made on an internal spline that was damaged.

    Thanks for posting. Never seen one of these in action. Seems like with a similar footprint you could have a shaper and be able to do more than just cut keyways. I assume there is a good reason to have a dedicated machine. What are the advantages of this machine over a shaper? How about advantages over a broach?

    • @MamcoMachining
      @MamcoMachining  5 лет назад

      This work could be done with a shaper however I believe the setup time to be less. The advantages I see for keyways again has to do with the amount of time to set up, it also takes very little power and the foot print is very small. I have seen these machines with attachments for doing internal splines, taper bores etc. and plan to make a few attachments when we get time. I believe the advantage the machine has over a broach is that a keyway can be put into a bore regardless of the size of the bore or the size of the key. What I mean by this is that if you had an odd ball bore like 2.264 the machine doesn't care where as if you were using a broach it wouldn't be a standard size like 2.250 so you would need to make a custom broach guide. Also the size of keyway as compared to the bore is endless. You could put an 1/8" keyway or slot in a 3" bore for example with the machine, again with a conventional broach and broach guide that wouldn't be possible with a standard set and would require some custom work. Again all this could be done with a shaper but I believe the setup time would be longer. We don't currently have a shaper in our shop but would love to get one but would still keep this machine.

      @@boomblooka if you got creative you could do a lot of shaper operations on one of these, you could make gears if you had the patience! Those tools look very much shop make able out of standard HSS stock.

    Why didn't you line up the metric keyway and increase its size?
    Can you adjust the speed of the cutter? The surface speed seems a little high?

    I see the table moving with reference to the over-arm support pillar. Would locking up the socket-head bolt at the back of the table clamp give you a straighter depth of cut?

    • @mikemorgan5015
      @mikemorgan5015 5 лет назад

      It does that by design. The table moves the part out of the way on the return stroke, like a clapper on a shaper. Notice that it moves away then just as the cutting stroke starts, it returns to its position. Also notice the control at the operators lower left moving in in time with the table.

  • @ego-xn7zu
    @ego-xn7zu 3 года назад

    I have the same machine but the table keeps moving as soon as the cutter makes contact so I'm getting a taper keyway any ideas??

    I use dealer gages to check the clamp it will let you know if it is clamping even.

  • @funone8716

    I can see the upper part of the rod deflect when the cutter bit hits the workpiece. Seems like it would work better if there was a round 'guide bushing' up top instead of just the V groove. These machines seem better than the Davis machines, they require a bushing in the bore for each size bore of the workpiece.

    • @funone8716
      @funone8716 Год назад

      I ended up with a Davis Keyseater after researching both them and these Morrison machines. The Davis uses the multi-tooth broach cutters which are much more expensive new. Luckily I was able to get almost every size used for a great price. The Davis machines can use a limited size bushing to do bigger bores, so no higher cost there. The Davis machine can do a keyway like the one in this video in about 2 minutes, way faster than this Morrison single cutter can. Plus the Davis strokes much faster.

    Nice to be back watched and liked your very first video and found you again now so subscribed to learn what you have going on, Going to broach that hole? No you are going to cut the key way, have never seen this style machine only know the broach and the scraper ways of cutting the key way, nice approach, great machine what a tool to have. We see the cutter band bar are supported by that overhead arm there neat, sorry got a little excited to watch this happening. Lance & Patrick.

  • @terrylinenberger378

    Had one of these in our maintenance shop at a box plant. after we got it we almost never used broches. The V clamp centers round parts with the cutter. The dial should have graduations on is to indicate depth cut and a stop to stop feed at the set depth. NEVER feed by hand! too deep a cut will brake the cutter and possibly the bar.

    • @MamcoMachining
      @MamcoMachining  5 лет назад +1

      Thanks for watching video. Yes I would agree great machine. You advise advise about not hand feeding is well taken. I always use the auto feed and as mentioned in the video I even baby it a bit and disengage feed after a few strokes so that the cuts can catch up a bit to keep from exerting to much pressure on the cutter. They also have an adapter plate to cut keys in tapered hubs. I have been looking for a used one to have on hand. We plant to take the table off in the near future to clean up the ways and gib. But really for what we do it works great.
