Air Pressure and Volume – What do I need to know?
What are the Suggested Lubricating Oils for Toggle-Aire and Direct-Aire Pneumatic Systems?
For Pneumatic Systems – Air tool Oils with an ISO grade 32 Non-detergent recommended. Note: Compounded oils containing graphite, fillers, etc. are not recommended for use with air line lubricators. Fire resistant oils containing phosphate esters should not be used with polycarbonate lubricator bowls. SMC-FRL Units
What are the Suggested Lubricating Oils for Toggle-Aire One-Shot Lubrication Systems?
For Pivot Points and Rams (One-Shot Lubrication System or Manual Oiling): SAE 20 or 30 Single Viscosity Non Detergent Machine Oil Class 2 Viscosity 100-200 S.S.U.@ 100 Deg. F., minimum aniline point or 200 deg. F –
What is the SV- Tooling Set-Up Valve and what purpose does it serve?
The Set-Up Valve is the small toggle switch feature located at the back of Direct-Aire presses – when flipped on, it activates and holds the ram to the down position. When flipped off – ram returns up. This feature is used for setting tooling to the proper depth more value added when combined with Adjustable Hard Stop option.
Is the Bolster Plate Removable?
Yes. It is not Welded. The plate is bolted and can be modified to allow parts to drop through. The opening under the bolster plate is 5″ x 5″.
Why does my Model 2000 NOT cycle when Start Button is pressed?
First check to be sure the batch counter is not full, turn OFF Batch Count or Reset Batch Count. If machine still not operating, be sure the machine is in RUN Mode, Ram Setup is OFF, Switch is in Normal Operation, Power Machine OFF/ON and try again. If still not operating, check I-7 on Diagnostics Screen – when power reset occurs – I-7 should be “ON” . If not, sensor needs to be adjusted. Turn AIR OFF – Remove Tooling Plate, sensor located on index unit at “4” o’clock position. Adjust IN or Rotate until Amber lit pickup on crest of station lobe. Turn machine Off, supply air Power on test. If OK, Turn OFF AIR – re-attached tooling plate and proceed to normal operation.
I am using the Two Hand Controller – But the Press Does Not Cycle. What do I do?
Couple items to check if you have a press running fully pneumatic with the SS-PB Two Hand Controller – see attached.
Can you please explain the Force Chart?
The displacement increments are DISTANCE FROM BOTTOM OF STROKE – I.E. –For example – if you need to push a bearing into a pocket and the push distance is 0.5” then the force chart is telling you at the beginning of the push(0.5” up from end of stroke) the press can only generate 945lbs of mechanical leverage at 80psi to start the push at that height. So if the push force required for the bearing is more than that, the this particular press model doesn’t have enough starting force to do the job and the press will stall out.
Press “max” force is rated .020” from end of stroke- When the ram is in the down(closed) position. This force is not affected by shortened strokes, as the end of stroke reference stays the same, it’s simple the retraction of the stroke that is limited.
The force/leverage that the press can obtain follows an exponential curve similar to a mechanical flywheel crank. Force at end of stroke is always the MAX force capable of being achieved by the press as the linkage/toggle is opened to optimal mechanical leverage. The advantage of Toggle presses – – highly repeatable to the end of stroke depth that is adjustable via the shut height– and develops a “squeezing” force that is controllable and accurate vs a standard air cylinder style press or hydraulic press that just applies force via impact.

In conclusion -A Toggle Press should always be working to end of stroke. – Additionally, our Joraco Toggle-Aire presses provide feedback via CSR-G2 – which requires the operator in a manual setup to maintain hands on the two hand controller, when the end of stroke is reached, the press will auto -retract – giving the feedback that the cycle was completed to the correct depth. If the press does not return, this is an indication that the shut height was set too deep. In an automated setup – the signal is sent to fire the press, and the end of stroke switch provides the feedback to PLC to say the work is complete, to remove signal and allow press to retract.
