Machine vice EuroLine EL
clamping against the fixed jaw
mechanically/hydraulically operated
For tool making, mould making, construction of jigs and fixtures and production
Machine vice with slide and base made from steel as well as hardened and ground guideways ensure high precision.
The clamping range of the machine vice can be easily adapted to the desired clamping position by quick adjustment with socket pins. The force build-up is made mechanically/hydraulically and is continuously adjustable. The compact design, the sophisticated technology, the extend accessory range for clamping jaws and the design with several sizes turn this machine vice into a cost-effective clamping system in proven Hilma quality.
The completely revised force transmission requires minimum effort on the crank handle. An angle drive (optional extra) facilitates the operation, e.g. in the case of longitudinal clamping on the machine table.
The optional clamping force preselection (retrofittable) enables the force to be applied in 6 stages up to the maximum.

Double Workholding System DUO
mechanically operated, clamping against the central fixed jaw
jaw width 80 mm
Application
Double workholding systems DUO are particularly suitable for double clamping - both in horizontal and vertical plane.
Description
Double clamping systems DUO convince by their short overall length, durability and precision.
The guidance and sealing principle works without any delicate sheet metal covers or plastic wipers.
The centrally arranged fixed jaw as a central jaw is without load and thus absolutely zero point stable.
The workpieces are positioned close to each other, and thus reducing the travel paths of the machining centre to a minimum.
The purely mechanical operation enables clamping also with low and always reproducible clamping forces.
Multiple clamping system MSH
The high-precision multiple clamping system MSH is modular and can be configured according to the requirement of the machining.
The field of application is in the production of small, medium and large series. MSH may be used as an individual system or in combination with additional elements (e.g. towers, bridges, base plates, zero point clamping systems) on all machine tools, machining centres and flexible manufacturing systems.
The simple, well thought-out design guarantees safe and user-friendly handling. The modular design allows any extension to suit specific requirements.Short set-up times, minimum machine travel achieved by high workpieces density, reduced tool changes and a high rate of amortisation, these are the economic advantages of using this system.
Special benefits
- precise, frictional connection between base and clamping module via fine teeth as well as patented eccentric clamping by means of one fixing screw only
- rapid set-up without measuring instruments using the scale on the base module and graduation marks on the fixed and clamping module
- different jaw openings and fix module width from 24 to 100 mm, (60 - 120 mm Goliath) (Linear only 60 mm)
- clamping modules with a rear contact surface accurate in size workpieces need not be accommodated "in mirror image"
- accommodation of a maximum number of workpieces any extension to the base modules is possible
- exact and repetitive accuracy of the workpiece position alignment or zero point adjustment using the machine spindle is not required
