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.
