Punch Machine Notes
Super 30/40-Mechanical Machines were made in 1960's & Early 1970's.
These Machines were basically just a
Super 30/30 with Bigger-Flywheels and Larger-Motor
and were Definitely NOT Good 40 Ton Machines!
Shops that insisted on Punching Large and High-Tonnage Holes with
Super 30/40-Mechanical Machines would, sooner or later,
Break the Piston and other Punch-Head Parts.
If you have a Super 30/40-Mechanical Machine,
I would NOT Punch Holes that Required over 25 Tons and I would
Not Punch 1/4" and Thicker Material as Replacement Pistons are Not Available.
So if you Break-it, you will need to Buy another Used Machine to Replace your Broken Machine that you can't repair, or else you will have to Run-Down to Home Depot
and Buy a Hand-Drill to make your Holes. Your Choice.
Because of these Breakage Problems with Super 30/40-Mechanical Machines,
Strippit Replaced it with the Super 30/40-Hydraulic Machine in 1976.
These were Excellent Heavy-Duty Machines
that would Punch 40-Ton Holes all day long with No Problems.
Strippit Stupidly Quit making these Excellent Machines about 1990,
LVD-Strippit Stupidly No longer makes any Single-Station Machines at all.

As stated previously, these were Excellent Machines.
But, of Course, there are some trouble areas now that they are getting old.
1 --- Machines are now about 30 to 45 years old. Do You Do Any Maintenance???
Did you EVER Change the Hydraulic Oil??? Yeah, I didn't think so.
So the the Hydraulic Oil in your Machine is now at least 30+ Years old.
But yet you wouldn't Dream of Not Changing the oil Regularity
in your Pick-Up Truck or your Wife's Caddy for Decades. Go Figure.
That Old Oil has Dirt & Water & Metal Particles in it that has Been Wearing-out
your Expensive Hydraulic-Pump, Hydraulic-Valve, Punch-Cylinder, Seals, etc.
Change The Oil!
2 --- Strippit really Screwed-Up here. They put a Course Screen-Filter that will
Stop Cock-Roaches & Floating Mice going up the Suction-Tube Pick-Up in
Oil Tank that goes to Pump. But it will Not Stop & Filter-Out Dirt & Metal
Particles in the oil that will Damage All Components in Punch System.
Common Good-Practice in Designing Any Hydraulic Systems is to put a
Spin-On Filter in Return-Line from the Hydraulic-Valve.
Hydraulic Systems, like on this
Super 30/40-Hydraulic Machine, have the Pump Running and maintaining
Oil Pressure to the Punch-Valve All the Time when Machine is Turned-On.
If not actually Punching at that moment in time, Valve just Dumps the oil through
a Return-line Back-to the Tank. A Low-Pressure Filter should be Inserted into that
return Line. But Strippit Did NOT put a Return-Line Filter on this Machine!
95-Percent of the time Machine is Not actually punching, so the oil is constantly
being sent back to Tank. If you were to Add a Filter to the Low-Pressure
By-Pass Line out of Valve, your Oil would be Constantly Filtered Clean
Preventing Many System Wear-Out Problems.
Pictures of Typical Small Filter-Mount & Filters are Shown Below,
but I would use a Much Larger Filter to handle output from
Big 10HP Motor & Pump.
If I owned 1 of these Machines, I would Plumb-in a Filter Assembly!

If you have "Lost" your Operation & Maintenance Manual
Buy a New Manual Before Starting on this Adventure!!!
I still have a few Manuals left For-Sale at this time,
and I have Included information of the Hydraulic Components.

3 --- Back-In-The-Day in 1975 when Strippit's Engineers built the 1st
Super 30/40-Hydraulic Machine, Engineer's put the 2 Hydraulic Hoses to
Punch-Cylinder on Outside of the Frame where they would be Easy to get to.
Then Strippit's Marketing-Pukes looked at it and said Move & Hide the Hoses
because they weren't Pretty! True-Story.
Remember Strippit's Marketing-Pukes when you Try to Un-Screw or Replace Hoses.
So Hoses were moved inside the frame where they are impossible to get to!
Every time you Punch with these Machines, the Hoses Jump & Flex, Inside the Frame,
from Punching Pressure Cycling on & off. After many years of this,
Hoses can Wear & Blow-Out, and are Extremely Difficult to Access and Replace.
You will have to drop-down the Heavy Punch-Head to get access to hoses,
another Very Difficult Operation.
If you are replaceing them, Take Old Hoses to a Good Hydraulic Supply House like
do NOT use the Cheaper 2000 or 3000PSI Stuff!
Later-On, in the Early 1980's,
somebody in Strippit's Marketing Dept. had a Wet-Dream in the Shower,
and came-up with the Idea of Bolting a Tool-Turret on the Side of this
Excellent Single-Station Machine. So Strippit Did. A 12-Station Tool Turret Was just
Bolted-on to the Left-Side of the Frame, and a Very Clunky Indexing Mechanism
would advance the Turret Very Slowly & Very Imprecisely 1 Station at a time.
This New Machine was called the T-SAF 30.
These Crappy Machines had many Problems, so Avoid them!
As if the T-SAF 30 wasn't Bad enough,
Strippit Marketing had Another Wet-Dream
and told Engineering Dept. to take the T-SAF 30 Machine and Bolt-on a CNC Control
to make it a Baby CNC Turret Punching Machine!
So a General Electric 1050 CNC Control & Servo-Drives were Just
Bolted-On to the Right-Side of the Frame. This new Machine was called the FC75/30. They somehow thought it would go over Big in Europe, but it never did.
But they did sell a lot of them in the U.S. Because they were Cheap.
These Machines are Automated Crap and should be Avoided.
As the T-SAF 30 and FC75/30 were Built off the Super 30/40HD Machine
The Punching-Head & Cylinder & Seals & Switches are all the Same
and use the Same Repair Parts and Repair Notes Provided Above.
4 --- As these Machines are now Decades old, Cylinder Seals can Wear-Out or even
Crack from old Age causing Punch-Cylinder to leak Oil at the bottom.
Cylinder-Bore may need to be Honed-Smooth if it's Scored from Dirt & Contaminants because you Didn't Change Oil regularly or add a By-Pass Filter.
Unfortunately, it's a Huge-Job to Replace Seals. I won't even do it.
Alan Suda, in the Mid-West may do this work if he's in The-Mood & has Time,
and Tom Penrod, on the West Coast can also do this work.
Otherwise, you will Need to do this yourself.
Depending on how far you need to go on taking this apart, Getting Repair Parts, Possibly Honing the Cylinder Bore, Etc.,
Budget a few days or even a Couple of Weeks Time to do it!
I believe both Alan & Tom Drop-Down Cylinder Assembly onto the Machine Table,
take-off Tool-Holder Base-Assembly and Cylinder Rod-End, Leaving the
Hydraulic Hoses On assembly, and just Replace the Lower Piston Seal & Wiper,
as this is were most Leaks occur.
Alan has a Special Laser-Cut Plate he Made to Jack-In Piston & Seals back into Cylinder. You may not be able to do it like them, it's a Experience Thing.
Some Shops will Pull the Cylinder out and send it, with a New Set of Seals,
to a Hydraulic Repair Shop to be rebuilt.
Be Very Careful, as the Cylinder Weights a 1/4 Ton!
5 --- Try to Not Damage Switches as they are Not made anymore!
Take Very Good Photos of Limit Switches & their Set-Up Before you take them all off!
If you are completely Disassembling the Cylinder, the #11 Switch Actuator Rod is
held-on to Piston only by a Item #10 Retaining Clip. I had a Machine where the Clip
Popped-Off of the Piston so Switch-Rod became Loose.
Customer had to Completely remove Switches, Pull Cylinder, sent it to a Rebuild Shop, and then reinstall everything back in Machine.
Then Switch Actuator Rod Popped-Off, Again!
Customer had to Completely remove Switches, Pull Cylinder, send it to the Rebuild Shop, Again. I Suggested Repair Shop Mike-The-Clip Groove and Install a Heavy-Duty (Thicker) Clip. It took a Month and Many Thousands of Dollars to get this Machine Finally Repaired, All over a 10-Cent Retaining Clip!!!
Re-Machine the Clip Groove on Piston if it is Buggered Up!
Make Sure a Heavy-Duty Retaining Clip is Installed and Rod is Installed Very Well!
5 --- There are No Electronics in a Super 30/40HD Machine.
Just the Punch-Head Limit Switches, and Several Relays.
Strippit Engineering was Confused by some New U.L.-Insurance Requirements in the Late 1970's when this Machine was designed, and so Relay Logic is Much More Complicated than necessary, and can be difficult to follow.
I replace Stock Relays with Special LED-Light Type which Lights-Up when
Relay is Pulled-In, making it Much Easier to Trouble-Shoot Problems.
6 --- For Un-Know Reasons, Strippit Stupidly made the Cams that go on the Switch Actually Rod out of 6-Sided Hex-Bar-Stock on a CNC Lathe.
Problem with this is the Tapered-Part of Cam actuates Switches OK,
but the Rod Rotates over time, and
6 Flat-Sides on Strippit's Cams do Not always actuate the switches correctly!
My solution was to have a Machine Shop make me some New Cams with No Flat-Sides!
Look closely at Cams I had made in Photos. I do not sell these Cams,
but if I can find my Drawings, I may post my Cam Dimensions we used, in the Future.
