Precision CNC Machining for Alignment & Spacer Blocks

Precision CNC Machining for Alignment & Spacer Blocks

Tight-tolerance alignment and spacer blocks with flatness, parallelism, and hole locations controlled for production accuracy.

Precision CNC machining for alignment and spacer blocks with flatness and parallelism held to ±0.0005″. Stable, repeatable geometry eliminates shimming headaches and misalignment downtime. Fast quoting and production-capable capacity for maintenance replacements or OEM runs.

Precision CNC Machining for Alignment & Spacer Blocks

We machine alignment and spacer blocks used to control mounting heights, maintain datums, and lock in feature relationships across frames, bases, and assemblies. Typical geometries include matched-height blocks, stackable spacers, keyed locating blocks, and riser blocks with critical hole patterns and faces held in tight relationship.

Machine base alignment blocks

Spacer blocks for machinery leveling and elevation changes

Locating blocks for fixtures, tooling, and weldments

Precision height blocks replacing shim stacks and packers

Rail, bearing pedestal, and gearbox spacer blocks

Jacking and support blocks for equipment installation

Alignment spacers in conveyor and material handling systems

How We Deliver Consistent, High-Accuracy Results

Matched feature heights and datums keep shafts, rails, and frames aligned across every block.

Single-setup machining minimizes stacking errors and reduces opportunities for tolerance creep between features.

Programmed offsets and in-process checks lock in batch-to-batch repeatability on critical dimensions.

Standardized routing and scheduling provide predictable lead times and stable, repeatable release patterns.

Tolerances

Flatness and parallelism on critical faces typically held to ±0.0005″.

Hole locations and key feature relationships routinely machined within ±0.001″ true position.

Prototype through 1–1,000+ piece runs with the same controlled tolerance stack-ups.

Tolerances

True position on port patterns and critical bores routinely held to tight, production-grade limits

Flatness control on sealing and mounting faces down to 0.0005–0.001 in, application-dependent

Consistent, documented tolerances maintained across repeat batches and scheduled releases

Common Features

Precision ground or machined faces for contact surfaces, mounting pads, and stackable block sets.

Patterned bolt holes, tapped holes, and dowel pin bores for repeatable locating and alignment.

Standardized setups with documented in-process and final inspection for every batch.
