Machined Knurl

 

Machining a strait knurl is an easy and clean way to produce a knurl. It does however require a means of dividing such as using a dividing head of some type.
If one uses this method it is good to not produce a sharp knurl.


Re: What's happend to my knurling???

 

Knurling is ?“not” a cutting operation but a forming operation. Keep that in mind. Too much swarf is an indication of not enough force being applied and doesn’t produce a clean knurl.

The work diameter should follow the rules here:

for the cleanest knurl. On the 7x lathes, a scissor type knurling tool usually gives better results than the classic bump knurler that's common on larger machines.

Pull the knurl wheels a measure them . Knurling takes a lot of pressure & sometimes? much more pressure then ya would think to make a good knurl .Pressure also varies depending on the material yer using . Like mentioned go in hard & fast . Be extra careful if yer using a brush to apply yer cutting fluid . If the bristles get caught & sucked into the knurl wheels we may be having a different conversation '

good luck

Re: What's happend to my knurling???

 

For successful knurl use the following steps.
1) Use cutting oil
2) Position the knurling tool as close as possible to headstock.
3) Switch lathe on and advance the knurling tool into the cut as quickly as possible and do not dwell. You must be aggressive here.
4) Do not retract knurling tool until knurl is complete as you don’t want a double cut knurl. It will be almost impossible to pick up a partially completed knurl.
I have not had a bad knurl in many years. Remember be aggressive!

Re: A rather useful tool

 

I have a Xerox laser printer and it is the only printer I know that does not have duplex printing. I have really cheap HP printers all with duplex printing.

To get duplex printing I have to manually reinsert the sheet, hopefully I get it right side up and in the correct direction.

But it (the copier) came at a premium and my boss wasn't willing to pay it.? The copier we bought instead had to be replaced about 4 years later - I suspect the Xerox would have lasted much longer.? But I still don't know if the cost would have been justified.

Xerox was never really a copier company. ?It was a paper and toner company -- the consumables generated the vast majority of revenue and profit. ?And guess what brand of supplies went into the majority of those "competing" copiers and printers? ?The rise of office computers catalyzed by the windowing interface greatly increased the creation of paper documents, generating more revenue through paper and toner sales than Xerox ever could've made trying to compete in the computer business.

Sure. ?And last time I busted my knuckles when the adjustable wrench slipped, I wiped up the blood with a kleenex, put on a couple of band-aids, and took a tylenol for the pain. ?

Xerox could never make their mind up.

They had their very own Bell Labs division in Palo Alto Research Center, but treated it as a place to exile smart but ?non-copier-oriented people from their HQ in Rochester, like the guy who invented the laser printer…

PARC invented :

The GUI - and sold the rights to use it to Apple, then dumped their stock holdings in Apple just before the stock split and blew up in the early 80’s?

Laser printing - guy who invented it later went to HP, IIRC, in any case laser printers were commercialized by Canon and HP.

The LAN and 10-Base-t Networking - That turned into a little company called 3-Com.

…and more I’m probably forgetting about

Re: A rather useful tool

 

Well, when I went to tech school in 68 and eventually got to the engine phase of learning, our teacher introduced himself as mr weber. Then he held up an adjustable wrench. He said that he never wanted to see one in anyone's toolbox nor used in class. Not on his engines. And a bit more. So to this day I call them weber wrenches. And to his word, when I was in another class we heard some yelling and shouting and then saw two guys running down the hall. And then a weber wrench flying down the hall after them. So yup, weber wrench it is.?

Re: A rather useful tool

 

When I was a kid I was taught by my 80 year old great uncle , a mountain man that one of the most important tools a guy could carry in a rig was a vise grip , the kind with the wire cutters on them . When I asked why he said " ya never know when yer gonna have to cut part of some ranchers fence to tie yer muffler or bumper back on " . Words to live by .

I have 2 large chain wrenches , they are real popular among my friends . Not sure how many years of hefting one of them up I got left in me though . Mine are probably 3 & 4 feet long without the chain .

Re: A rather useful tool

 

Chain Vise Grips are a useful, well made tool. Mine are genuine, not Asian copies. I've got one pair that I added an extra length of chain for torturing larger things ;-)

Re: A rather useful tool

 

Vise Grip is not same without the name Vise Grip on side.?
Back 1970's there a lot cheap Vise Grip copies and in a shop they would not not last a week. So all shops would only buy the name brand.?

In my shop the Vise Grips where zin plated over chrome plate cut on missing Vise Grips no one want zip Vise Grips.
