2.2 Intended Use
The mechanical clamp VCMC-R is used for clamping dry, rigid workpieces onto table grid plates. It may be used
only in combination with a suitable grid table. The VCMC is to be installed by the customer.
The VCMC-R is aligned with brackets and secured against horizontal slipping. Switching on the operating vacuum
fixes the clamp to the table. The workpiece is then clamped by means of a vertical stroke of the clamping disc.
To guarantee safe operation of the VCMC, ensure the following:
• During installation, the clearance between the workpiece surface and the clamping disc must be no more
than 6mm. Caution: crushing hazard!
• Do not allow anyone to reach between the workpiece and the clamping disc during the lowering process.
When the operating vacuum is switched off and the vacuum circuit is vented, the clamping pressure on the work-
piece is released and the VCMC is released from the grid table.
The product is built in accordance with the latest standards of technology and is delivered in a safe operating con-
dition; however, hazards may arise during use.
The product is intended for industrial use.
Intended use includes observing the technical data and the installation and operating instructions in this manual.

3 Product Description
3.1 Description of Mechanical Clamp VCMC
3.1.1 Use
The VCMC-R is used for clamping dry, rigid workpieces. It may be used only in combination with a suitable grid ta-
ble plate. The clamping force and stroke are powered by evacuation of the VCMC. Since the contact surface of the
VCMC and the vacuum block are at the same height, you can clamp a workpiece in mixed operation as well.
3.1.2 The Adjustment Mechanism
The VCMC is equipped with a quick-adjustment mechanism. It allows adjusting the clamping range in steps of
5mm to conform to the workpiece.
3.1.3 Clamping the Workpiece
When the vacuum is activated (evacuation of the vacuum circuit of the suction cup mounting) by the higher-level
machine, the lifting cylinder is activated and the workpiece is clamped.

3.3 Near Field Communication (NFC)
NFC (Near Field Communication) refers to a standard for wireless data transfer between different devices over
short distances.
An NFC chip is integrated in the locking disc, which functions as a passive NFC tag that can be read or written by a
read or write device with NFC enabled, such as a smartphone or tablet.
Read access only can be obtained via a website viewed in a browser. This does not require an additional app. It re-
quires only that NFC and the internet connection are enabled.
6 / 15 EN-US · 30.30.01.03049 · 00 · 10/21

For the best data connection, center the reading de-
vice on the NFC symbol.
The reading distance is very short for NFC applications. If necessary, find the position of the NFC an-
tenna in the reading device used.
The following parameters can be queried via NFC:
• Product group
• Type
• Part number
• Index
• Serial number
• Year of manufacture (encoded)

7 Start of Operations
7.1 Clamping the Workpiece
CAUTION
When the clamping disc is lowered, body parts may be present in the clamping range
Crushing of body parts
4Ensure that the clamping height is set so that the distance between the clamping disc and the
workpiece is less than or equal to 6mm.
4Do not reach into the clamping range while the clamping disc is being vacuum-lowered.
EN-US · 30.30.01.03049 · 00 · 10/21 13 / 15

WARNING
Flying workpiece due to insufficient clamping force during processing resulting from incor-
rect setting of the clamping height.
Risk of injury due to flying workpiece
4Adjust the clamping height such that the VCMC uses its maximum clamping force. While doing
so, ensure that the lifting force of the VCMC is less than or equal to6mm.
4Personal protective clothing must be worn.
üThe locking disc must be entirely closed.
üThe workpiece is set.
1. Evacuate the appropriate vacuum circuit on the
grid table via the higher-level machine.
ðThe VCMC is clamped to the grid table and the
workpiece is clamped by lowering the clamping
disc (≤6mm).
2. Carry out both a visual and manual check to make
sure that the workpiece is securely clamped by
pulling on the workpiece.
ðIf the workpiece can be moved, then it is not sufficiently tightly clamped. Check the clamping height and ad-
just it if necessary.
ðIf the clamping is sufficient, then machining of the workpiece may commence.
7.2 Machining Limitations
WARNING
The workpiece comes loose during machining and is flung away by the machine.
Risk of injury from flying parts.
4Ascertain the maximum machining parameters and observe them.
The clamping force is limited, meaning that it can withstand machining forces only up to a certain point. Accord-
ingly, the operator of the mechanical clamp is obligated to establish for themselves (by experiment, slowly and
carefully increasing the machining forces) the optimal settings and number of mechanical clamps necessary to en-
sure that the workpiece does not slip or even come loose during the machining process.
Schmalz assumes no liability for damages resulting from slippage or release of workpieces due to faulty adjustment
of machining parameters.
14 / 15 EN-US · 30.30.01.03049 · 00 · 10/21

7.3 Releasing the Workpiece
CAUTION
Falling objects resulting from the workpiece being released (deactivation of the vacuum)
Risk of injury
4Personal protective clothing must be worn.
Deactivating the vacuum, and thus reducing the vacuum to the level of the atmospheric pressure, releases the
workpiece and eliminates the vacuum clamping force between the VCMC and the suction cup mounting. The
clamping disc is raised by spring force.
8 Warranty
Schmalz guarantees this system pursuant to our General Terms and Conditions of Sale and Delivery. The same ap-
plies to spare parts, provided that these are original parts supplied by us.
Wearing parts are not covered by the warranty.
