These instructions walk users through the process of assembling and setting up a Schunk Vero-S NSE mikro 49-13-V10 clamping module on a Pocket NC V2 machine. An example of how this work holding option can be used can be read about in Penta Machine Company’s “Schunk Zero Point Fixturing on the Pocket NC V2” blog post.

Please note that these instructions assume that a user has purchased the Schunk workholding kit from Penta Machine Co.

Schunk Module Prep

Follow the steps below to prepare the Schunk module for installation on the Pocket NC B-table adapter.

1. Remove the Schunk module from the blue Schunk box. Be sure to locate the small bag holding the seals and fasteners that come with the module.

2. Locate the four (4) black o-rings that came with the module. Remove them from their bag and place them on the table.

3. Turn the Schunk module over so that its writing and QR code is faced down on the table.

4. Locate the four (4) bores on the backside of the module’s outer ring.

5. Using tweezers, place an o-ring in each of the four (4) bores. Be sure to press them down well to ensure they are fully seated.

B-table Adapter Prep

Follow the steps below to prepare the B-table adapter for the Schunk module.

1. Inspect the 6 threaded holes on the top of the B-table adapter and locate the one that has a slightly larger bore milled into the top half of it. It should be in line with one of the large counter bored mounting holes. Mark this hole with a marker by drawing a line straight out from it.

Install Schunk Module on B-table Adapter

Follow the steps below to ensure proper installation of Schunk module onto the Pocket NC B-table adapter.

1. Rotate the B-table adapter so that the marked hole is in the 12 o’clock position when looking down on the adapter.

2. Turn the Schunk module over so that the Schunk logo and QR code is face up.

3. Rotate the Schunk module so that the locating pin pocket is in the 3 o’clock position when looking down on the module.

4. Taking care not to lose or displace any of the four (4) o-rings installed previously, set the Schunk module on/ the B-table adapter, maintaining the clocking set in steps 1 and 3. Press the module’s boss down into the adapter’s bore until the outer ring of the module meets the adapter.

5. Begin hand threading the fasteners that came with the Schunk module (5 black and 1 silver) into the holes on the top of the module. Make sure the silver fastener goes in the hole that corresponds with the mark on made on the adapter earlier. Start all six (6) fasteners by hand before moving on to the next step.

6. Once all six (6) module fasteners have been started by hand, use a 2.5mm allen wrench to tighten them down in a criss cross pattern to ensure even pressure and prevent binding.

7. Install all six (6) of the black fastener covers that came with the Schunk module into the heads of the the fasteners installed in step 6. Make sure the covers are fully seated in the fastener heads and counter bores.

Air Component Assembly

Follow the steps below to install the air components necessary to operate the Schunk module.

1. Using a 7/16” open end wrench and adjustable wrench, install the two (2) NPT push-to-connect adapters into the threaded ports of the air control valve. The adjustable wrench will be used on the control valve and the 7/16” wrench will be used on the adapters. Tighten until snug.

2. Using the 8mm open end wrench, install the rotating push-to-connect fitting in the bottom of the B-table adapter. Tighten until snug.

3. Measure the distance from the Pocket NC’s B-table to the desired location for the air control valve (e.g. a mounting hole drilled in the side of an enclosure).

4. Cut the 6mm air hose to the length of the distance found in step 3.

5. Push one end of the newly cut piece of air hose into the rotating push-to-connect fitting on the bottom of the B-table adapter and push the other end into the push-to-connect adapter on the short end of the air control valve.

6. Take the remaining length of 6mm hose and push it into the push-to-connect adapter on the long end of the air control valve. This can now be routed to an air supply (like an air compressor). If the air supply uses something other than 6mm hose, it simply needs to be adapted in away that will allow it to connect to the long side of the air control valve.

7. Provide a minimum of 72 psi (5 bar) to the system.

8. Locate and watch the clamping jaws inside the module’s center hole. Toggle the air control valve back and forth to make sure the jaws open in one valve position and close in the other.

9. With the module’s jaws closed, listen for leaks in the system. If a leak can be heard or felt, check all connection points as well as the plugged (with a set screw) port on the side of the B-table adapter.

Machine Installation

Follow the steps below to install the Schunk work holding assembly on the Pocket NC V2 machine.

1. Safely disconnect the air supply from the air system assembly.

2. Disconnect the 6mm hose from the rotating push-to-connect connector on the bottom of the B-table adapter. This is done by pushing on the release ring at the end of the connector then pulling on the hose.

3. With the Pocket NC’s B axis in its home position, place the four (4) 1/8” dowel pins in the B-table. One will be placed on each side of the 12 o’clock and 6 o’clock position.

4. Place the Schunk module and B-table adapter assembly onto the B-table of the machine while aligning it with the dowel pins previously placed.

5. Using the four (4) M4 fasteners, fasten the work holding assembly down to the machine’s B-table. Tighten in criss cross pattern until snug using a 3mm allen wrench.

6. Reconnect the 6mm hose to the rotating push-to-connect connector on the bottom of the work holding assembly (the hose will have to pass through the hole in the B-able) and restore air to the system.

Stock Prep

In order to hold stock using the Schunk work holding system the stock needs to be prepared properly and have the proper hardware installed.

Use the drawing below to machine the necessary features in the stock then follow the steps below to install the hardware needed to clamp the stock to the work holding system.

1. Once the stock has been machined to have the features shown in the above drawing, begin installing the hardware by locating the Schunk clamping pin, Schunk indexing pin and the M3x14 SHC screw.

2. Turn the stock upside down so that the newly machined features are face up. Place the clamping pin’s 6mm boss in the stock’s 6mm bore.

3. Using the M3x14 SHC screw, fasten the clamping pin to the stock. Tighten until snug. Making sure the outer lip of the clamping pin seats against the stock.

4. Install the indexing pin by placing the pin’s 4mm post into the stock’s 4mm hole. The pin may require a few taps with a hammer to seat it all the way.

Stock Installation

After the work holding assembly has been assembled and installed and the stock has been prepared, the stock can be fastened to the fixture. Follow the steps below fasten the stock to the fixture.

1. Provide a minimum of 72 psi (5 bar) of air to the air system previously set up.

2. Toggle the air control valve so that the module’s jaws are open.

3. Place the prepared stock on the Schunk module, inserting the center clamping pin into the center hole of the module.

4. Rotate the prepared stock on the module until the indexing pin drops into the indexing pocket of the module.

5. Make sure the bottom of the stock is fully seated against the top of the module all the way around and then toggle the air control valve to close the module jaws and clamp the stock down.

6. Ensure the stock is securely fastened by testing it manually (pushing and pulling on it).

Conclusion

Moving forward, all that has to be done to hold different stock on the machine using the Schunk workholding is repeat the “Stock Prep” and “Stock Installation” steps above.
