SCHUNK Releases Versatile Clamping Module For Automated Machine Loading

SCHUNK’s VERO-S NSE-A3 138 clamping module is specifically designed for automated machine tool loading as well as for applications in handling, assembly and automation technology. The module is part of the extensive SCHUNK VERO-S modular system, which enables more than 1,000 possible combinations for efficient workpiece clamping.

For reliable workpiece and clamping device changes, the automation component is equipped with a powerful blow-off function, which carefully cleans the bearing surface during the changing process. In addition, a spring-actuated cone seal prevents chips or dirt from penetrating into the interface.

VERO-S NSE-A3 138 features a pull-down force of 8,000N or 28,000N with activated turbo function, as well as a high dimensional stability of the module body, providing rigidity in automated quick-change solutions.

Depending on the application, the modules can be combined in any quantity. Centring inserts with flexible elements ensure positional orientation with a high repeat accuracy and maximum process reliability in automated operations. The repeat accuracy is <0.005mm.

The actual clamping is done without any external energy supply via spring force; it is form-fit and self-retaining, ensuring the workpieces remain safely clamped in the case of a sudden drop in pneumatic pressure. A pneumatic system pressure of 6bar is enough to open the module.

If the modules are used individually, a standard integrated anti-twist protection ensures a stable position in the highest configuration. Through its integrated media transfer, fluids with permissible system pressures of up to 300 bar can be transferred, for example, to control clamping devices using Plug & Work or to supply components for automated monitoring.

As part of the VERO-S modular system, the automation module benefits from a variety of combination options—from standard plates to SCHUNK TANDEM clamping force blocks to mechanical vises from the SCHUNK KONTEC series.

Schunk Investing €85 Million In Expansion Of Production Facilities

Schunk Investing €85 Million in Expansion of Production Facilities

Gripping systems and clamping technology provider Schunk is investing around €85 million in expanding its production facilities in Brackenheim-Hausen, Mengen, and St. Georgen in Germany, and in Morrisville, North Carolina, in the United States.

Around 42,000sqm of total production and administration space is being created, starting with the US plant, where the new buildings were officially handed over recently. In addition to the production area expansion, Schunk Intec USA created a 4,000sqm administrative building, which features a Customer Centre, where users can experience Schunk’s components live and receive additional know-how in technology forums and workshops. The new building was inaugurated in early May with an official ceremony followed by a Family Day. Schunk has invested a total of almost €10 million in the expansion of the site.

Meanwhile, €40 million are being put into the Competence Centre for Gripping Systems in Brackenheim-Hausen, Germany. The extension covers an area of 22,000sqm and represents a doubling of the existing production area.

Schunk is investing another €30 million in the Competence Centre for Lathe Chuck Technology and Stationary Clamping Systems in Mengen, in the district of Sigmaringen, Germany. Here, 12,000sqm are to be added for production and R&D.

Around €5 million were invested at the St. Georgen site in Black Forest, where the production area was doubled with an increase of 4,200sqm.

“In the coming years, we will experience a boom in automation and digitisation worldwide, and we’ll only be able to handle this by having the right capacities,” said CEO Henrik A. Schunk.

For several years, the company has been successfully focusing on these two trends and concentrating its resources and know-how. Schunk expects high growth rates, especially for mechatronic and increasingly intelligent clamping devices and gripping systems.

The company also recently announced its cooperation with AnotherBrain, one of the world’s leading specialists in artificial intelligence (AI).

Schunk Launches Manually Actuated Clamping Module

Schunk Launches Manually Actuated Clamping Module

Schunk has extended its modular system for workpiece direct clamping with the release of the manually actuated series VERO-S WDM-5X. Enabling a defined clamping situation, reliable simulation and collision-free, highly efficient machining of five sides by means of basic and add-on modules, the  VERO-S WDM-5X clamping modules are actuated without the use of any media and independent of machine peripherals in no time at all via an Allen key.

One single turn of the tightening screw is sufficient for secure connection of clamping modules, either with one another or with the corresponding basic modules. The clamping modules can be used independent of the pneumatic system in external tooling stations, for instance, or in a very wide variety of machines. These can be combined with nearly all types of machine tables by means of flexible fastening systems.

Key elements of the series are basic modules in the heights 75mm, 125mm, 150mm and 175mm, which can be combined using add-on modules at heights of 75mm, 100mm or 125mm. In addition, the series includes a wide variety of different clamping bolts that can be integrated according to the size and shape of the relevant workpiece. Various reduction adapters enable five-sided machining free of interference contours. Freeform surfaces can also be clamped quickly and easily via height adjustment adapters.

Regardless of the height of the clamping pillars, the direct clamping modules are supplied with compressed air via a media transfer unit that is registered for patent, and locked via a force-locking and positive-locking connection with pull down forces of up to 25,000N (with 50Nm actuation moment). An integrated pull-down function ensures maximum hold. The actual workpiece clamping takes place in an energy neutral manner via spring force; it is a self-locking and form-fit clamping. The workpieces remain safely clamped even if the pressure in the air system were to drop suddenly. Presence of a workpiece can also be detected with the VERO-S WDP-5X.

Horn Unveils New Cutting Insert System

Horn Unveils New Cutting Insert System

Paul Horn GmbH presents the new 32T system for grooving and parting off on Swiss-type lathes and smaller fixed-head lathes. With a precision-sintered grooving insert and central clamping screw, the tool system offers high indexability of the cutting insert and direct entry into the insert seat of the tool carrier. Additionally, there is no need for clamping elements, which may have a detrimental effect on chip flow. The screw head of the clamping bolt does not introduce interfering contours and therefore permits both grooving on a collar and parting off directly at the spindle. The grooving insert can be used as a neutral insert and as both a left-hand and a right-hand insert. The 32T system completes Horn’s portfolio of triple-edge cutting inserts by offering a solution for smaller-scale applications. By adding the new system to its range, the tool manufacturer is responding to customer requests for a triple-edge cutting insert system for Swiss-type lathes and other smaller turning machines, in particular in applications where space is at a premium.

The maximum groove depth of the system is 4 mm with a groove width of 2 mm or 2.5 mm. For grooving operations, the inserts are available with both straight and full radius cutting edges. Horn offers the indexable insert with a 15-degree chamfer for parting off. A cylindrically ground chip breaker geometry makes for reliable chip removal. The tool carrier is designed as a square shank of 10 x 10 mm or 12 x 12 mm cross section. Each version features an internal coolant supply and is available in both left-hand and right-hand designs.
