3FG25

Heavy-duty electric gripping for demanding CNC

  • Up to 25 kg form-fit payload - handle large, heavy workpieces
  • Up to 450 N gripping force - secure demanding CNC parts with normal grip
  • IP67 protection - operate in machining environments with coolant and chips
  • Centric three-finger design - position round workpieces accurately in machine chucks
CNC machine tending
Load and unload heavy metal workpieces in machining environments with coolant, chips and demanding production conditions.
Material handling
Transfer, sort and package large parts using internal or external gripping and configurable fingertips.
Assembly
Grip and position heavy components for insertion and mounting with centric three-point contact.
01

Handle heavy parts with centric control

Three synchronized fingers centre large round workpieces for stable handling and accurate placement. The 3FG25 supports form-fit payloads up to 25 kg and force-fit payloads up to 15 kg.

25 kg Maximum form-fit payload
02

Choose the grip for the workpiece

Use internal or external gripping with either normal grip for known diameters and forces above 300 N, or flexible grip for varying diameters with force up to 300 N.

2 modes Normal or flexible grip
03

Built for harsh machining environments

IP67 protection helps the electric gripper operate around coolant and flying chips. A mechanical brake holds the applied gripping force without power consumption and retains the workpiece if power is lost.

WHY 3FG25

Heavy-duty gripping for demanding production

Three synchronized fingers centre round workpieces as they grip. Form-fit handling supports payloads up to 25 kg, while force-fit gripping supports up to 15 kg when the application conditions match the datasheet limits.

Normal grip is designed for known diameters and provides up to 450 N. Flexible grip handles unknown or varying diameters with force up to 300 N. Both methods support internal and external gripping.

The IP67-rated design is built for machining workshops where coolant and chips are present. A brake maintains the applied gripping force without continuous power and retains the workpiece during power loss.
