Spring plunger 280-1

Work supports, with threaded body When it is about increasing machining accuracy, the work supports are ideal components to avoid vibrations and deflection while machining workpieces. The threaded body variants allow horizontal as well as vertical mounting into the clamping fixture. With this flexibility, compact fixture designs can be realized also in space-critical conditions. The hydraulic fixing of the plunger can be combined with the hydraulic clamping of the workpiece or separated. There are two work support methods to advance the plunger: 1. Advance via spring force: basic plunger position extracted 2. Advance hydraulically: basic plunger position retracted Special features: compact fixture designs possible horizontal and vertical mounting possible plunger fixing combined with clamping or separate possible with protecting metal wiper pressure oil supply via drilled channels standard work supports and special designs available Operating pressure: pmax. 500 bar Advance method: hydraulically or via spring force Plunger: Ø 16 mm, stroke 8 mm Support force: max. 12 kN at 500 bar Spring force min. 8 N (spring) 10 N (hydraulic) Spring force max. 13 N (spring) 23 N (hydraulic) Oil connection drilled channels Wiper: soft wiper and metal wiper
