    Default Horizontal versus vertical Milling

    I'm wondering what advantages a horizontal milling machine has over a vertical spindle machine .

    Is it easier to cut gears with a horizontal mill ?

    Default Mills

    Greetings chaps, It is the type of work you are doing. I had to caselate some 1 1/8 11 TPI nuts the other day and I started with the vertical head but soon changed to the horizontal format and it was much easier on the machine. Cutting gears presents the problem of the cutter. DP Cutters are expensive and there are about 7 or 8 in a set. I have seen single point fly cutters used to cut gears but only in one off situations. And of course a dividing head of some sort is also required. Is this a query in regards as to what sort od a mill you would be looking for. Yours 4-6-4

    It depends a lot on the opperations you wish to perform,but most can be done on either type of machine.

    Sometimes it can depend on the HP or physical size of the machine,at times you may not be able to use any bigger than a 3" face mill on a vertical but you could use a 6" slab cutter on a similar sized horizontal.

    If you machining multiple parts you could possably gang mill with a horizontal where normally it is only one opperation at a time with a vertical..

    Cost was arbors,spacers and assorted cutters for a horizontal could be dearer.

    It is generally easier to machine arbors for a vertical.

    I prefer to cut most gears on a vertical although the larger module and lower dp gears are better suited to a horizontal.

    I find it easier to set up my gear cutters on the vertical compared to the horizontal,more so because my datum is easier to measure from.

    Let's see.

    On a horizontal:

    Depth of cut is greater.

    Width of cut is greater.

    Rigidity of cut is *much* greater.

    Tooling is generally more expensive.

    Gear cutting is simple.

    On a vertical:

    It's often easier to see what you're doing.

    Sometimes you can set the head up to allow odd angle cuts, but you can do this on a horizontal if you have a tilting angle plate.

    I've got both. If I'm removing serious metal or cutting gears, it's the horizontal mill every time. If I'm using an end mill then it's a job for the vertical mill.

    Default Right

    Ok

    Interesting . I will have to look around for some cutters for the Cash horizontal Mill I just aquired. It did come with cutter ..looks to be a new unused face / side cutter . I will take the table into the engineers in town to be resurfaced ..it has rust on it , needs a good clean up . The cross feed and table sideways feeds have worn acme nuts , some play is evident . The coolant pump is there on it , its driven by a clever gearbox with a worm drive arragnement from the motor . Will take some pics

    Dear mike what other attachments does it have. If it has a vertical head not a problem I changed from a Parkinson to my Arno because it had all the gear. Yours 4-6-4

    I prefer the vertical for visibility, but the horizontal is a lot more rigid, even when not using the arbour and just using a collet chuck.
    The only problem with the horizontal cutters is the price, but if you look around they can be found reasonably cheap.
    Having both gives you the best of both worlds.

    I bought a lot of them off of Mick Moyle a few years back for $2 each. OK they needed resharpening for the most part but you're getting a big chunk of HSS for $2, how bad can that be?

    Anyway having cutters that need resharpening means you have a perfect excuse to buy a T&C grinder.

    I didn't get much tooling with this mill ( it came with a nice vice ) , but I will look around and see what I can find. The Arbor in it seems to have a 1" diameter , to hold cutters with a 1" bore .

    The fed screw has 5 tpi . The suds pump is seen in the last pic , the drive belt is missing

    I took a few pics
