Pressure gauge as an option for exact clamping force display and monitoring. A unique HILMA advantage. Your benefits at a glance:   Clamping force / process safety Application of clamping force Adaptation to the machine tool

without VarioLine with VarioLine Using VarioLine clearly increases the utilization of your machine tool ! The clamping device can be individually adapted to different distances of travel, to working space, clamping surface and machining task. User-friendly set-up for differently sized workpieces is performed in a jiffy. The use of a pressure gauge (an optional extra) permits exact, continuous clamping force display (important when carrying out rough and finish machining in one operation) and exact clamping force monitoring. The clamping force can be applied manually using a crank handle...

Standard tapped holes in both sides of the fixed jaw for precision workpiece stop Slots and tapped holes for top step jaws to obtain very large jaw openings integral mechanical-hydraulic force transmission Hardened and ground guides Make your choice: based on page 6, parameters •• Length of the base •• Hydraulic or mechanicalhydraulic slide •• Pressure gauge •• Vertical design •• Positioning slot •• Positioning holes •• Mounting grid Clamping edge for clamping claws •• Angle drive Quick coarse adjustment of the desired clamping range using the socket pins Longitudinal and crosswise k eyways...

Technical data Mechanical-hydraulic design, manual operation 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. Optional extra Top jaws Optional extra Angle drive Hydraulic design, for use in semi or fully automatic operation Connection to a separate hydraulic pressure transducer, e.g. a hydraulic power unit. Coarse...

Standard jaws to obtain very large jaw openings * = Tolerance ± 0.01 mm, ** = only top step jaws for slide for clamping of rectangular workpieces without parallel pads. These jaws allow holes to be drilled near the edge. Used in pairs only. c for clamping one workpiece with nonparallel clamping surfaces or two workpieces with differential tolerances. a for horizontal and vertical clamping of cylindrical workpieces. a 16 MnCr5, supplied oversize, for preparation of special jaws by the customer. a Clamping jaw, extra high for safe clamping of high workpieces. Used as single jaw or in pairs....

QIS base jaw with permanent magnets Part no. Jaw change in a few seconds with downthrust effect: The base jaws are fastened to the s lide and to the fixed jaw using screws. The interchangeable jaws can be inserted and removed quickly. They are kept in place by two permanent magnets. QIS interchangeable jaw, smooth Part no. a Fasten the base jaws to the slide and to the fixed jaw (one-off task). QIS interchangeable jaw, serrated Part no. Slide the desired interchangeable jaw in the guideway against the base jaw. QIS interchangeable jaw, crowned Part no. The permanent magnets and guide pin...

The SlimFlex jaw system allows 3-side machining of centrally c lamped workpieces with dimensions less than the jaw width of the clamping device. Inserts keep the workpiece off the base jaw, which provides optimum access from three sides for the work spindle. Scale for rough adjustment Space for work spindle Adjustable inserts Inserts reversible Space for work spindle SlimFlex jaw system, standard version 2 Step insert Part no. SlimFlex jaw system Part no. SlimFlex jaw system without step inserts with step inserts Part no. Insert C45 soft Slim Flex jaw system, QIS version Insert C45 soft QIS...

Efficient multiple clamping using floating central jaws Using floating central jaws for multiple clamping, the working area in an NC machine is utilized to the maximum. The resulting reduction in tool changes and travel contributes to a significant reduction in costs per piece. Can be combined with all HILMA clamping systems of types EL, NC. Central jaw AL hard anodised Lower grip •• the lower grip prevents workpieces from rearing up Workpiece without / with clamping edge Workpiece without / with "lost head" •• longer machine running times allow to operate several machines •• complex...
