Workholding

Magnetic and vacuum chucks, vises, clamps, locators and fixtures for holding parts during machining.

  • Collet chucks

    Workholding collet chucks for turning, axial location, gripping range, force limits and scoped runout specifications.

  • Expanding mandrels

    Internal-bore workholding, expanding sleeve designs, axial location, diameter ranges, runout, and product-specific force and speed limits.

  • Fixed-jaw machine vises

    Fixed-jaw location, movable-jaw clamping, pull-down mechanisms, mounting and product-specific force limits for machining vises.

  • Fixture plates

    Fixture-plate grids, locating bores and threads, mounted geometry, material choices and the limits of pitch, tolerance and torque specifications.

  • Four-jaw independent chucks

    Independent jaw adjustment, eccentric workholding, centering measurements and assembly-specific mounting, force and speed limits.

  • Magnetic chucks

    Magnetic workholding circuits, switching systems, contact limitations and the distinction between pull-off force and cutting-load resistance.

  • Rotary tables

    Machining rotary-table indexing, simultaneous control, angular accuracy, torque and workpiece-support limits.

  • Self-centering vises

    Opposed jaw motion, center versus fixed-jaw datums, centering specifications, shallow gripping and product-specific force and torque limits.

  • Soft jaws

    Machinable chuck and vise jaws, loaded machining, mounting interfaces, contact geometry and limits on force, speed and accuracy.

  • Steady rests

    Lathe support arrangements, self-centering rollers, contact geometry and the separate limits on diameter, loading clearance, force and speed.

  • Strap clamps

    Rigid clamp straps, heel supports and threaded load paths, with lever-force calculations and limits on contact, access and torque.

  • Tailstock centers

    Live and dead centers, center-hole contact and taper mounting, combined loads, and axial thermal-growth compensation.

  • Three-jaw scroll chucks

    Synchronized manual chuck jaws, centering limits, jaw configurations, mounting and the distinction between static gripping force and rotating conditions.

  • Toe clamps

    Low-profile edge restraint, cam and wedge mechanisms, contact choices and the separate meanings of clamp travel, screw torque and holding force.

  • Toggle clamps

    Over-center linkage, holding capacity versus applied clamping force, spindle position, pneumatic examples and fixture-load paths.

  • Tombstone fixtures

    Multi-face tooling columns, locating interfaces, fixture mass, rotary clearance and the limits of geometric accuracy specifications.

  • Trunnion fixtures

    Rotating fixture structures, indexing and simultaneous motion, support interfaces, hydraulic services and the distinction between mass, moment and inertia.

  • Vacuum chucks

    Pressure-difference workholding, effective sealed area, leakage and lateral restraint, with product examples and a bounded force calculation.

  • Zero-point clamping systems

    Repeatable fixture interfaces, locating studs, pull-down and holding force, actuation variants and the limits of mounting accuracy.
