Servo-pneumatic fatigue test machine
2-10kN bench top system

A standard range of machines where the specifications can be adjusted to meet customer requirements.

Frame

• Rated up to 25 kN tension & compression.
• Fixed bottom crosshead.
• Movable top crosshead clamped by pinch bolts.
• Actuator mounted on top cross head.
• Two chromed solid steel columns.
• Top and bottom crosshead and feet powder-coated (RAL7035)
• Space between columns: 405mm
• Standard column length: 1200mm.(650mm maximum daylight space).
• Different column lengths available on request.
• Weight, including actuator: 220kg

Actuator

• Low friction grade pneumatic actuator.
• Mounted on crosshead.
• Capacity options (shown as the static rating for 7 bar air supply):
  • 2kN
  • 5kN
  • 10kN
  • 15kN
  • 20kN
  • 25kN
• Standard stroke options:
  • 50mm
  • 100mm

Load cell

• The fatigue-rated load cell can be mounted on either the top or bottom crosshead.

Controller

Si-Plan Digital Control and Data Acquisition System with a Windows^® PC which is utilised to provide the user interface for machine control and data capture.

Pneumatic supply

The compressed air supply for the actuator should be:

• Between 5 and 10 bar.
• At room temperature.
• Free of oil contamination.
• Filtered to 5 micron maximum particle size.

Advantages of pneumatic

• High reliability – low maintenance.
• Major price advantage over servo-hydraulic and screw-thread machines.
• Little or no heat generated.
• No fire risk.
• Runs from filtered workshop air or bottled air.
• Low inertia.
• Inherent predictable stall thrusts.

Accessories

Accessory options

• Clip gauge.
• Grips
  • Ball nut & ball cup.
  • Flat and round.
  • Wood’s metal pot.

400mm² slotted tooling plate to suit M12 T-nuts.
