ROEMHELD VL Hydraulic and Mechanical-Hydraulic Operated Vario Line Machine Vice

KOSTYRKA® support elements have been used reliably since 1969. They stabilise components during machining and contribute to minimising vibrations. The greater running smoothness means an increase in product quality.

ROEMHELD M8.200 Electronic Control Module for one modulog module and one operating element.

ROEMHELD F9.461 Threaded-body type Coupling Elements without Coupling Stroke

• Maximum operating pressure 200 bar
• Threaded-body type, ND 4
• Nominal diameter: ND 4
• Maximum flow rate: 8 l/min
• Maximum coupling force 4.0
• Positioning tolerance, axial: +0.05 mm
• Positioning tolerance, radial: 2 mm

These automatically closing couplings have a flat surface and do not have protruding elements for sealing. Therefore exact positioning is not required and a radial positioning misalignment of up to 2 mm is admitted. Cleaning of the coupling surfaces is easily possible due to the flat surfaces. Because of the omitted active axial coupling stroke completely new solutions for the coupling motion can be realised.

ROEMHELD D8.021 Power Units, basic version

• Flow rate: 0.9 .. 6.2 l/min
• Operating pressure: 50 .. 500 bar
• Reservoir volume: approx. 11 l
• Usable oil volume: approx. 6 l
• Motor: 0.75 .. 1,5 kW – 400 VAC

ROEMHELD C 2.531 Directional Control Valves ND 10

• Ports: Flange with O-ring sealing
• Adm. flow rate: 120 l/min
• Hydraulic oil: as per DIN 51524
• Supply voltage: 24 VDC
• Code class: IP 65
• Maximum Operating Pressure: 315 bar

ROEMHELD B1.950 Single Acting Threaded Body Work Supports

• Maximum operating pressure 500 bar
• External thread: M45 - M90
• Maximum load force: 16.8 - 102 kN
• Plunger diameter: 20 - 50 mm
• Plunger stroke: 12 - 20 mm
• Maximum flow rate: 25 - 100 cm³/s
• Elastic deformation: 1.8 - 4.5 µm/kN

Hydraulic work supports are used to provide a self-adjusting rest for the workpiece during the machining operations. They compensate the workpiece surface irregularities, also deflection and vibration under machining loads.

ROEMHELD B1.852 Swing Clamps with Sturdy Swing Mechanism: Cartridge type, position monitoring optional, double acting

• Maximum operating pressure 350 bar
• Maximum clamping force: 6 - 22 kN
• Rod diameter: 16 - 32 mm
• Piston diameter: 23 - 45 mm
• Clamping stroke: 12 - 15 mm
• Maximum flow rate: 10 - 57 cm³/s

The hydraulic swing clamp is a pull-type cylinder where a part of the total stroke is used to swing the piston. The favourable area ratio (piston/piston rod) allows high clamping forces already at relatively low oil pressures. For high flow rates the swing speed is limited by an orifice in the clamping port. Thus, uniform clamping of several swing clamps is also possible when oil supply is effected through a common bore.

ROEMHELD 1.7301 Clamping and Supporting Element: cartridge-type version, self-locking, double acting

• Max. operating pressure 300 bar

ROEMHELD B1.4843 Bore Clamps: Cartridge type, without centring function, double acting, for bore diameter 7.8 - 17.7 mm, max.operating pressure 250 bar

• Double acting
• Operating pressure 250 bar maximum
• Bore hole diameter ranges from 7.8 to 17.7 mm
• Maximum low-clamping force 5.1 - 9.8 kN
• Expansion force , radial: 9 - 14 kN

This bore clamp is a double-acting pull-type cylinder. An exchangeable clamping bushing is fixed to the piston. The four segments of the clamping bushing are radially expanded with spring force by a pyramid-shaped clamping bolt. Thus the expansion force is always the same and independent of the hydraulic clamping pressure.

ROEMHELD B1.542 Double-Acting Block Cylinder with Externally Threaded Piston Rod used universally for all hydraulic-operated linear movements

• Operating pressure 500 bar maximum
• Piston diameter ranges from 25 to 63 mm
• Rod diameter ranges from 16 to 40 mm
• Stroke: 50 and 63 mm
• Maximum push force: 24.5 - 155.9 kN

This double-acting block cylinder whose piston rod is provided with an external thread. Fixing elements as for example rod end bearings, which are available as accessory, can be screwed onto the external thread.

ROEMHELD B1.461 Threaded Body Cylinder: single acting with spring return and double wiper

• Operating pressure 500 bar maximum
• Piston diameter ranging from 12 - 32 mm
• Stroke 10 - 20 mm
• Clamping force at 500 bar (5.7 - 40 kN)
• M22 - M48 external thread

These threaded-body cylinders can be threaded directly into tapped holes in the fixture down to the hex-section of the cylinder body. Spacings between cylinders can be minimised when cylinders are arranged in a row, since the oil is fed through drilled passages in the fixture.
