Features
- Linear force progression for No. 305 and No. 307
* High force at the end of stroke for No. 311
* Precise adjustment of the press depth via micrometer fine
adjustment
* Guides require little maintenance, have little wear and are
locked against rotation. This results in precise working
and a long service life
* Optimum guidance and clamping due to dovetail guide on the
press head
* Quick set-up
* Exact alignment of ram bore to the table within 0.05 mm
* Height adjustment using a crank
* Precision bores in ram and column base plate

Options
• Additional charge applies
1) Throat depth frame only available with frame No. 7-600
2) Increased throat and higher frame lead to smaler nominal forces for No. 311
3) The weight was determined with hand lever position 45° forward (guide)
4) Typical values; can vary ± 3 mm due to casting and production tolerances
5) Adjustable stroke with stop clamp (in the scope of delivery)
Other available Options:
* Nickel plated – cast parts are electroless nickel plated, steel components black oxide finished, aluminum anodized, precision steel surfaces are untreated
* Custom paint – press and column can be painted to customer's color specification
* Bores for adapting tooling – customer specific sizes can be supplied
