TS tower workholding systems are used on horizontal machining centres, in vertical machining in connection with 4th axis, but also on 5-axis machining centres. The applications range from manually equipped machines to pallet stations and fully automated systems.

- 2 sizes for optimum design to the machining centre
- Clamping of 4, 8 or 16 workpieces with standard jaws
- Clamping of different workpiece dimensions also on one side
- Purely mechanical build up of the clamping force
- Easy and safe operation
- Large jaw openings and high flexibility due to extensive range of clamping jaws
- Highest stability by design as a monoblock
- Optimum protection against contamination and wear through patented guidance and sealing
- Process-safe application of clamping force, also when using grip jaws

The tower workholding systems TS convince with their durability and precision. The patented guidance and sealing principle works without any delicate sheet metal covers or plastic wipers. The design as a monoblock, without interfaces to individually screwed workholding systems, stands for high stability and high accuracy. The centrally arranged fixed jaw as a central jaw is without load and thus absolutely zero point stable. The workpieces are positioned close to each other, thus reducing the travel paths of the machining centre to a minimum. The purely mechanical operation enables clamping also with low and always reproducible clamping forces. These characteristics turn the tower workholding systems TS into a flexible standard fixture for a wide variety of applications in modern production.

Chucking systems
The SPEEDY connect series are fast closing clamps made of high-quality tool steel and a housing made of anodised, high-strength aluminium with very low space requirements due to compact external dimensions. The system is clamped mechanically using springs, the force is boosted pneumatically and the system also released pneumatically. The SPEEDY connect is self-locking due to the integrated spring assembly.

The integrated polling unit acquires and signals the clamping state via three signals (?clamped without nipple?, ?nipple clamped? or ?released?) on LEDs on the rear of the element, as well as digital signals for forwarding to a higher-level controller. The polling is designed so it is resilient to interference and is suitable for use in welding systems.

WS 5.4600
80 und 120 mm
21 bis 40 kN
The workholding systems SCS are especially advantageous for 5-axis machining.
The compact design allows a good accessibility of the tools to the workpiece. Collision-free tool paths and a 5-sided workpiece machining can be achieved with short standard tools.
Due to the good swarf protection, workholding systems SCS are particularly suitable for the use in pallet systems.
The stability of the clamping systems and the high retention force due to the use of the special grip reversible jaw with hard metal coating make pre-embossing of the workpieces superfluous.

clamping against the fixed jaw
mechanically or hydraulically operated

- Compact design
- High precision and accuracy of the manufactured workpieces by high rigidity
- High zero-point stability
- Sturdy design and good swarf protection
- Large jaw openings
- Extensive range of jaws
- Easy to maintain

Protect Difficult-to-Access Surfaces against Deflection

To stabilize the components that could swing or bend during machining, the ROEMHELD Group has developed a new series of either single or double-acting work supports. They excel by a small extension shaft to reach difficult-to-access recesses and cavities.
The elements are suitable for all mounting positions and are screwed in into the fixture body in a space-saving way. Developed for the use in machine tools with low-pressure hydraulics, they reach already at 70 bar a support force of 3 kN and can absorb side loads of up to 300 N.
For clamping, a support plunger with a diameter of only 10 mm is hydraulically extended and contacts the workpiece surface with spring force. The support plunger is radially locked by a thin-walled locking bush. When unclamping, first the locking bush will be released again and then the piston is retracted by spring force - or hydraulically in double acting versions. The maximum stroke is 6.5 mm.
The work support is protected against contamination by a metallic wiper edge and a FKM wiper. Positive air pressure of up to 0.2 bar can be connected to the vent port to effectively avoid the penetration of liquids. The interior parts are protected against corrosion.
The work support can be used in an extremely flexible way because of the only 16 mm wide extension shaft that is available with a freely selectable length from 20 to 100 mm. Thus, the single-acting variant with a length of 86 to 116 mm can be used in machine spaces; the double-acting version is available with dimensions from 120 to 200 mm.
The double-acting version is also suitable for the use in automated processes: hydraulic extending and retracting of the piston allow short clamping and unclamping cycles.

The patented workholding systems of the series HILMA MC-P are highly versatile due to numerous variants and an extensive range of accessories. They excel by high stability and precision with very good accessibility and comprehensive swarf protection. There are versions for concentric clamping, clamping against a fixed jaw or position flexible clamping as well as mechanically or hydraulically operated variants. Types with a jaw width between 40 mm and 125 mm, maximum clamping forces from 8 kN to 35 kN and a large selection of jaw openings up to 6-400 mm are on offer.
Thanks to the compact design, collision-free tool paths and the use of short standard tools in 5-axis machining are possible. A further advantage for the user is the option to clamp workpieces for clamping cycle 1 and 2 in one system. Raw and finished parts can be machined without retrofitting. Due to the good swarf protection, the workholding systems are particularly suitable for the use in pallet systems.

Besides 5-axis machining and concentric clamping, the position flexible version MC-P Z Balance is suitable for individual or series clamping of bars, rails, profiles, guide rails or housings. The compensating function avoids deformation during clamping of delicate or long components so that a precise and process-safe manufacturing is guaranteed. Also workpieces that are fixed by internal contours or positioning elements can be clamped concentrically.
A comprehensive range of jaws with interchangeable step, pendulum and prismatic jaws, as well as interchangeable inserts with hard-metal coating or grip serrated complete the product group. On request, MC-P workholding systems can also be delivered as customised versions.

8-12 mm
120 bar
The hydraulically-operated bore clamp is particularly suitable for clamping in workpieces with smooth bore holes in the support surface ranging from 8 to 12 mm in diameter. The workpiece is put directly onto the hardened surface of the bore clamp and will not be deformed during clamping. Since clamping is effected within the bore, the remaining surfaces are free for machining on 5 sides.

- axial clamping in simple smooth bore holes
- compact eccentric design for limited space
- different support heights
- hardened support height
- easy exchange of clamping bushings and tie bolt
- 3 pneumatic monitoring functions can be connected
- separate connection for positive air pressure protection
- integrated bleeding screws

Pneumatic swing clamps are used for applications which require only low clamping forces. The installed magnetic piston allows monitoring of clamping and unclamping position.

When pressurising the element, the clamping arm swings and lowers by 90° to the clamping position and then lowers to the clamping point. The position monitoring gives the required information regarding the position of the piston, but not regarding the position of the clamping arm. Monitoring is made by electronic sensors which detect the magnetic field of the magnetic piston. The switching points can be continuously adjusted by displacement of the magnetic sensors.
