Here's the Clamp/UnClamp macro's just in case anyone could use them.

I think the Sleep() command takes it's Argument in milliseconds??

Well more macro's in the works at the moment.

I can't remember the allowed custom macro rules for mach, I just been working on Collet open and close macro's.   Ideally I'd like to use the more conventional M10,11.   But they seem to be reserved for something (Probing?)

Even replacing those with my own, the new ones seem to be ignored.   I was able to use M20,21 though !   Thats also normally an clamp/unclamp signal on many machines.   But I think for Indexers.

I don't really want to start using high number M codes for those that are very conventional.

For anyone thats interested here's the M6Start macro for the 4 station turret on my Hardinge.

It passes the requested station # to the Cubloc PLC via a holding register mapped to 66 in mach and D12 on the Cubloc.

The Cubloc always has it's actual station # available in D13 (67 in Mach) via it's turret encoder routine.   = 0 when invalid = 1 to 4 for valid stations.

I'll probably post the Cubloc program when it's developed a bit more.

The Macro below is partially based on Hoods Churchill Macro.  Thanks Robin...

Hood.

The servo's are not that big.   300W just about the same size as the orignals.   Only these are higher speed rated, and I have also changed pulley ratio from 1.85:1 to 2.5:1.

Not much done today, except real work, and sweeping up all the cut cable ties and bits of wire!   Though I just been getting familiar with modbus again, never wrote all my settings down last year!

Well here's a little picture of in progress work this week, just tidying up a lot of the wiring.

Loads more to do, but it's mostly all worked out and tested.  I just have to rewire as I want it to stay.

Transformer is 45v 1kVA giving 64v DC for the servos, The two contactors to the right of it turn it on via a soft start resistor (Seen top of pic).  Timer relay(Far right)  operates the righthand contactor to short out the resistor.

Larger contactor below supplies power to the spindle drive.   Circuit breakers to its left.

Grey wire running through all contactors is part of the Estop chain.   Blue wire hanging around in there, is the temporary enable Neutral going to all the contactors coils for testing.   The circuit is designed with all coil Lives coming straight from the same supply as the load through a breaker.  If any load trips it's own breaker ALL contactors drop out, also putting machine into Estop.

Not as much as I am      It's got beyond the ridiculous!     

 I do remember quite a clearly a friend seeing it all in pieces and saying "you'll never get that going again"   I can almost see the lump forming  in this throat at the moment

More work done today.    Wired up spindle encoder, Make up new encoder cables for the axis.

The cabinet is looking rather busy again these days.  Though I think I've made a neat job of it.   Have to fit a panel to the door of the contro cab so i can mount yet mroe DIN rail.

Thought about fitting the new seal kit to the turret but had more important work to do.  I'll do that when I have cleared a few jobs this week.

There was a HXL on Ebay located in Ireland last week.    Had no picture, so I was not sure if it was a HXL or HXL-S    the S just means Siemens control.   The plain HXL is older and had  a GE control, it looked different too.

Hood.   Just about all the original solid dovetail bed Hardinges are the same footprint.

The CHNC's come up a fair bit, and are very useful especially in 16C spindle variants.  Their turrets are more complex though.

Theres a couple on ebay at the moment.   But rather too much money I think.   Mind you they cost a bomb new.   My HXL-S was close to 40 grand in 1986.

The HXL's were realyl a toolroom machine, with 4 fewer turret positions but had a powered tailstock..

I also have a smaller 5c Hardinge which runs Ahha s/w, but does have the 8 station turret.

Parts are not cheap especially from Hardinge,  this week I had to buy a seal kit for the turret (loads of o rings and Quad rings) Said bye bye to another 100 quid!   Would of cost me that to take it apart measure everything and then make enquiries with local stockists.   They were all Viton too which made them harder to find over the more comon Nitrile.

Hood.   Much bigger than a student.    Mine is 16c spindle so 42mm (1 5/8") through capacity.   Original machine weighs in close to 2 tons in amall (6ft x 3ft) footprint. So rigidity is massive for this class of machine

Rab.   The partoff system is quite desirable as it also fits the CHNC's    Bear in mind that system is hydraulic driven by a hidden air motor powered pump in the right hand side of the base.

The chuck if a 16c powergrip costs around $3000 new from Hardinge!

It's a very desirable machine, but if anything like mine a lot of work.

I have a HXL-S.   It's a fairly complex machine and prone to a few problems.   You have to bear in mind these machines are 25+ years old now, the Iron is usually good, it's the rest!

I converted to AC spindle as I have a dislike for large DC spindle drives.  The HXL-S had a 4-5kW DC spindle.

Most of the Pneumatics were screwed, mainly leaks and I hate to have my large compressor starting up every 5 minutes!   So All 5 port valves were replaced.  Also just this week all the seals in the turret.   Mines a 4 way turret.

Every piece of electrical cable inside the machine enclosure had got brittle with age and exposure to cutting oil.  All replaced.

Old servo motors had loose magnets and again full of oil.  So those were replaced. 


The list goes on........    But I'm still happy, I got a machine with Good Iron in tight condition, and the rest is 98% Brand New.
