Tight-tolerance workholding blocks with controlled clamping faces, flatness, and squareness for production reliability.
We machine workholding blocks for rigid, repeatable clamping with tight, production-grade accuracy and fast quoting. Tolerances to ±0.0005″ on critical faces and reliable lead times prevent misaligned parts, clamp slip, and fixture fire drills.
Precision CNC Machining for Workholding Blocks
We machine workholding blocks that secure production parts when standard vises or jaws fall short. Typical geometries include dedicated fixture blocks, modular risers, and locator blocks with tightly controlled flatness, squareness, and hole patterns. Designs are built for rigidity, repeatable locating, and fast loading in demanding production environments.
Dedicated fixture blocks for single-part or family-of-parts machining
Modular workholding blocks for grid, rail, or slot-based systems
Riser blocks to elevate parts for multi-side access
Locating blocks with pins, keys, or shoulders for repeatable positioning
Clamping blocks and stops for resisting cutting and pull forces
Soft-block workholding for delicate or high-finish components
Precision reference blocks for inspection, probing, or in-process checking
How We Deliver Consistent, High-Accuracy Results
Critical faces, datums, and locating features machined in one process so clamping geometry stays aligned.
Minimized setups reduce stack-up error, keeping blocks square and parallel from prototype through repeat orders.
Documented production methods and inspection checkpoints hold the same dimensions across batches and multi-year programs.
Clear scheduling and realistic lead times reduce rush jobs, overtime, and unplanned fixture downtime on your floor.
