3FG15 Three-Finger Gripper
Centric three-finger gripper for cylindrical parts, ideal for CNC lathe tending.
The 3FG15 grips cylindrical workpieces from 4 mm to 152 mm in diameter with three contact points, automatically centring the part for precise placement in machine chucks. It supports both external friction-fit and internal form-fit gripping, with payloads up to 15 kg and gripping force from 10 N to 240 N — competing with far bulkier and less flexible finger grippers.
Key Features
- Three contact points for accurate centric positioning
- External grip diameter 4–152 mm, internal 35–176 mm
- Payload up to 15 kg in form fit
- Fingers mountable in three positions for different force and diameter ranges
- Four supplied fingertip types in steel and silicone
