Hi,

"I am going to take this path but do I need to use queing commands? !1L2 to transfer sub to $2 to eject part after operation?"

No just change mode again to standard G630 and put eject in...

Hi

You don't need G140 as K argument on tool line is better method. G140 only really used for specific applications and on older machine without K function

Program in $1 - not $2

This mode...

Material spec - Aluminium is notoriously variable in diameter when you buy it from your stockholder but general H9 spec for raw material. If you were running lots of aluminium I'd look at adaptive...

Typical A20 inch machining data - raw data viewed in windows notepad or similar (you won't see #016,#020 on screen only values in mc data screen)

You could try using simple macro command and use a subroutine rather than loading external subprogram. This way all data is kept in one program - eg

If you are able to you may have more success with thread rolling - i've done M1.6 many times in material like surgical steel and titanium for body jewellery - dies last for ages and rolled thread...

As others have said all dimensions are radial.

Also G2 and G3 radius are the wrong way round - machine looks at it from spindle perspective - clockwise is G3

R value in Tdata will work with 0...

Use right hand tool for cut off - small bar

"Can a G3 code be used for an endmill the same way it is used for a turning tool?"

Yes - All you have to do is change the plane selection before milling e.g

M5 G98
M58 S3=2000

M18 C0 ...

I think its something to do with subspindle encoder and programming feed / rev in G620 mode.

Try running the subspindle whilst drilling (you'll need to close collet M15 first to get above 200...

Without seeing exactly what you are trying to achieve you have a couple of options

1 In G610 mode you do not need to command M141 to retract as if you change mode to say G630 it will retract...

Hi,

Check your compos page under parameters for a option known as "program pre analysis check" - or something like that.

If this is active the machine will precheck the program for syntax...

G84...........D2 , R1 will work on your L20

Some other things to check maybe if you think that chips is causing the problem

1 - If coming from drill turn your HP coolant line on and leave for 2...

"G84 Z.570 R.03 F.03125 S300R1"

Normally when working on back spindle you'd need to add D2 (spindle 2) and a comma before the R1. E.g

G84 Z.570 R.03 F.03125 S300 D2, R1

However to the best...

"We encountered problems running hex material in our L20 with the bar loader timing out during attempting to load.. Ive thought of a way to fix this but it would require editing the actual barloading...

I know K machine very well - very quick and accurate

Even though its Fanuc controlled, as opposed to Mitsubishi, the programs are nigh on identical and you could take a program from your L20 and...

Hi there,

I've used AGB's widely both the older type from JBS and the new ones from Citizen. In theory every machine should have one and to be honest for extensive aluminium use I'd say its worth...

What are channel liners?

Depending on your barfeed make channel liners are usually plastic or rubberised guides in the barfeed to support the bar and bar pusher during the machining cycle. Some...

"For those of you that use high speed spindles, do you run them at full speed or throttle them down to hit a precise SFM? Is there a down side to running at full speed?"

Hi,

Depending on your machine and cost you might want to go down route of high frequency spindles from the likes of Ibag.

Hi

All the answers regarding your G50 query are correct but in case you were unaware (you did say you were a newbie) the M118 command is cancelling the collision detection at the start of the...

If you've not already tried them would suggest you speak to Spanish Citizen agent who should be able to help

Good luck

I think this is a terminolgy thing, I believe when the poster refered to "simple rego collet and drill chuck" they were referring to the Collet and Collet Chuck system, not a conventional "drill...

Hello

If your machine has rigid tapping then a simple rego collet and drill chuck as you would use for a standard drill is all you need. Special holders like spring ones are not required with...

Hello

Sounds like your Y to Z axis ratio is out. If not code specific this could be caused by you programming Y axis co-ordinates in radiall as opposed to diametrical. Citizen M32 series 2 used...

Hi there

Engraving option as you say is probaly too slow for your requirement. We use roll markers from German company Hommel & Keller here in the UK - Just plunge on and rotate C axis by required...

Historically peoples perception of screw machines was that you had to have very large batches to make them economical but this is no longer the case and certainly here in the UK the majority of users...
