GRESSEL Machine Vises and Workholding Systems
GRESSEL AG is a Swiss maker of machine vises and workholding since 1923: centric and 5-axis vises, gripos and grefors machine vises, gredoc and gre4doc zero-point systems and clamping jaws. Plant in Aadorf.
C2.0 and C3 centric vises
C2.0 has a sealed, backlash-free ball bearing spindle: 25 kN for C2.0 80 at 90 Nm, 35 kN for C2.0 125 at 100 Nm, 50 kN for C2.0 160, repeatability ±0.01 mm for sizes 80 and 125. The C3 for small parts gives 16 kN at 50 Nm with 45 and 70 mm jaws.
- C2.0 force up to 50 kN
- Repeatability ±0.01 mm
- C3 force 16 kN
- C3 jaws 45 and 70 mm
grepos-5X and grepos-5X-E 5-axis power vises
grepos-5X with high jaws clamps the part by lever within seconds; force is set steplessly from 5 to 40 kN. The electric grepos-5X-E offers a programmable 120 mm stroke, a 5–420 mm clamping range, up to 40 kN (80 kN total), IP 67 sealing and 24 or 48 V supply.
- grepos-5X force 5–40 kN
- grepos-5X-E stroke 120 mm
- IP 67 sealing
- 24 or 48 V supply
gripos and grefors machine vises
gripos builds force in a power cartridge, set steplessly from 4 to 40 kN, with 160° lever clamping; the whole spindle unit comes out for cleaning, and every variant exists with hydraulic drive. grefors sets 10 to 100 % force with one crank turn; grefors 160 reaches 60 kN.
- gripos force 4–40 kN
- 160° lever clamping
- grefors 160 up to 60 kN
- Hydraulic gripos-H
S2 single, D2 double and M1 multiple vises
S2 and D2 for pallet automation give 5–50 kN at low tightening torque, jaws change with two screws, S2 repeatability is ±0.01 mm. The D2 base body is nickel-plated against corrosion. M1 multiple vises: 90 mm jaw width, 260–650 mm rail length, hardened and ground toothing.
- S2 and D2 force 5–50 kN
- S2 repeatability ±0.01 mm
- M1 jaw width 90 mm
- M1 length 260–650 mm
gredoc and gre4doc zero-point clamping systems
The mechanical gredoc system is 30 mm high: 20 kN pull-in force per locating pin, repeatability under 0.01 mm, no air or hydraulic supply. gre4doc is built into pyramids and consoles: four bolts on a 52 × 52 mm pitch, 15 kN at 30 Nm, repeatability under 0.005 mm.
- gredoc height 30 mm
- Pull-in 20 kN per pin
- gre4doc pitch 52 × 52 mm
- Repeatability to 0.005 mm
Jaws, adapter and swivel plates
The range covers over 130 top jaws in widths from 22 to 160 mm. GRIP jaws with 92 HRC carbide pins hold hardened material up to 58 HRC at a 3 mm clamping depth; coated jaws raise the friction coefficient by a factor of 1.5–2.5. Adapter plates exist for C2.0 and gripos-R.
- Over 130 top jaws
- Jaw widths 22–160 mm
- GRIP jaws up to 58 HRC
- Friction up 1.5–2.5 times
Selecting GRESSEL vises and workholding
Vises are chosen by the task and the clamping force.
For 5-axis machining and pallet automation there are C2.0 centric vises (25, 35 and 50 kN in sizes 80, 125 and 160) and the C3 for small parts, grepos-5X power vises with 5–40 kN and the electric grepos-5X-E. For 3-axis machines there are gripos machine vises (4–40 kN) and grefors, with up to 60 kN on the grefors 160.
Multi-part machining is covered by D2 double vises and M1 multiple vises with 260–650 mm rails. For fast changeovers the vises sit on the mechanical gredoc zero-point system (20 kN per pin) or on gre4doc, built into pyramids, with a 52 × 52 mm bolt pitch.
GRESSEL AG, the manufacturer
GRESSEL AG was founded in 1923 in Aadorf, Switzerland, as a mechanical workshop and has been part of SCHUNK SE & Co. KG since mid-2014. Production in Aadorf runs under ISO 9001:2015, and sales partners operate in over 50 countries.
