How to Use a Horizontal Mill K&T Controls and Lubrication

hello David I'm Annessa here today we're gonna go over the controls and function and lubrication of a Kearney and trekker horizontal mill this particular mill happens to be from the 40s and it is the model H I bought it personally from the University of California UC Berkeley my model happens to include the high speed vertical tilting milling attachment with built-in crane we'll go over that in a separate video here's a view from the front of the machine our feeds are adjusted here this can be adjusted whether the machine is running or not and that goes from a half-inch per minute to 20 inches per minute this is the knee down and up you pull this out and now you can activate power feed down and up this is the cross slide out and in you pull it out now you can activate the power feed out and in this is the cross slide dial goes to 250,000 s with a lock this is the knee dial it's 125 thousand style with a lock this is a close-up of how to actuate the power feed for the knee right now the handle is actuated but if we pull back on it now we're able to switch the power feed down and you see that manual cannot be restored until in the middle it's the same operation for the cross feed we're in manual you pull it out and now out and in and when power feed is actuated manual is impossible so here's the operation of the power feed for the cross slide out at 20 inches per minute stop and in same with the knee down 20 inches a minute stop the spindle must be running in order for power feed to actuate however with the spindle off but the machine motor running rapid feed is possible in all axes the rapid feed handle is found on the right hand side of the machine you pull up to actually a clutch this is the table feed handle with a stop bypass also a neutral lock so that you can't accidentally hit it into feed table feed we're still at 20 inches per minute rapid neutral other direction rapid cross slide feed out rapid neutral in and rap it [Applause] new feeds down rapid new feed neutral up and wrap it [Applause] right now the spindle is on I'll turn the spindle off I pulled the clutch handle to turn the spindle off now we have no table feed but we do have Rapids in both directions we have no cross slide feed but we do have rapid same with the knee down this is the drive clutch actuation handle right now the drive clutches off that would be on on this box is the magnetic switch on and off switches the back side of the handle actuated off and that is start and stop let's turn the machine motor on the spindle is off now the spindle is on you can see it moving here spindle off machine motor off 40 taper spindle with Drive dogs these are the over arms two and seven-eighths on the model h here's the operation of the table stop here's the operation of the table stop bypass you can lift up on the handle bypass the table stop temporarily for that crack table get block saddle lock the knee has two locks one to the knee also has stops two of them here this is the stop handle or stop arm the saddle has stops as well and the stop is here stop actuator there's the adjustable stop on this arm your feed rate adjustable in both directions while we're here this is your oil fill port for way I'll i use factor number two you fill this oil the motor slings oil around on two weeks and that lubricates the table ways and screw cross feed ways and screw knee ways and screw automatically while the machine is running this model has a nine by forty six inch table that is set up to run cutting oil underneath this guard is a brass screen here's the screen so the cutting oil on both sides of the table the chips are filtered by this screen and then it runs into a trough which goes underneath the table into this brass telescoping tube which runs down to the base of the column empties out into the base of the column which is hollow and full of oil cutting oil I use mobile met for 26 non-staining cutting oil you do not use water-soluble in here you'll rot your machine these caps are to move in case oil runs down the side of the machine when you're doing certain cuts that happens it runs down the side of the machine into this track and is filtered through that screen back into the base the oil pump actuator is behind this door this is where the clutch is and the oil pump there's the clutch mechanism I'll move the handle off to belts fed by the motor down lower is the oil pump it's fed off of a shaft actually this shaft so this is the oil pump shaft you pull this up which disengages the shaft from the oil pump there's the oil pump shaft right here and you pull that back down to actuate the oil pump if you buy one of these machines that's been sitting around for a lot of years I wouldn't expect that oil pump to work without you having to take it apart and clean all the sludge out of the base and the oil pump but it's not that hard on the side of the machine is the fill port for the saddle gearbox oil and there's a sight glass for the level the drain obviously under here over on the back side over on the left-hand side of the machine is the sight glass for the spindle gearbox oil and the spindle gearbox also runs a shaft that powers the saddle gearbox looking up higher we have a sight glass for oil feed in the gearbox for the spindle so there must be flow in this sight glass when the motor is running on the back of the machine we have the fill port for the spindle feed gear box we have the drawbar there's the arbor support which needs oil when you're running an arbor bushing I store it on my over arms I have three of my arbors stored on the over arms that's not a factory or stock there's a drain for your cutting oil drain port in the back I have a spigot on mine your electrical goes into the machine there the motor access is here three horsepower lubrication points 420 weight oil it's one there of course you'd lubricate these lubrication point on the manual table handle there's a cup there incidentally I don't think I showed you the table dial there's two hundred and fifty thousands this spins freely so that it's not whipping around under power feed and you have to push it to get it to work manually oil cup 20 wait there's no handle on the other side of the machine oil cup 20 wait this is a view of the cross slide screw this is a brass telescoping pipe that holds the drive shaft for this the saddle feeds that shaft is run on the side through a gearbox here throws shaft here so as the saddle goes up and down that gearbox runs up and down on that key door spline shaft so the power is continuously available to the saddle there's the nice crew which is lubricated automatically through the splash wicking mechanism over arm supports should be lubricated manually let's move to the controls on the side of the machine we'll start with the over arm crank handle this has two positions for one handle or two there are two over arm locks one here and one here inch into sixteenths once those are loosened the over arms will extend out both at the same time or only one one is useful when you're hanging things on the over arms it's a lot easier to hang on one arm first then finish it off on to the fun part this handle is your selector for your top row of speeds bottom row of speeds or fast and slow your speed selector is here you'll probably have to wobble the spindle with one hand while you turn this to get the gears to mesh up which is what I'm doing with my right hand so right now we're in slow 45 slow 35 next divet slow 58 and slow 73 and on around the circle 1 1993 switch this too fast or the upper scale we're in 666 and 851 and on around the circle we go 521 412 around and around and around from 35 revolutions per minute to 1400 below the selector handle is the forward and reverse selector you have to wobble the spindle push it in get it to actuate that's reverse and forward on this particular model the oil spigot is here let's run some oil the spindle has to be running for the oil pump to be on now if you do happen to be running oil on a cut that runs back here like this the machine is made [Music] to run that oil back down the machine no problem it's all design so it runs down the side of the machine trips here these caps are for mobile dte 26 heavy medium dte 26 heavy medium there's a shot of the over arms coming out we'll do a separate video on setting up for horizontal milling there's a close-up of the 40 taper spindle with drive dogs we'll do a close-up of the universal vertical high speed milling head that's the drive gear I store their includes a coolant or oil holder this is the pipe where the oil comes out on mine it goes up over here we have arms on a hook to a bracket on the side of the machine see this bracket this doesn't come on all the machines this is specifically here to store this vertical milling head on the side of the machine permanently so you don't have to go fishing for it and with this crane it takes all the weight off of it makes it easy to install we'll make a whole video for that here's some tooling it's another Arbor spacers bushings boring bars 40 taper tooling handy-dandy tables square here's a view from the back in the top Kearney and trekker horizontal mill model H alright guys David I'm an SC thanks for watching take it easy you
