Product overview
Rigid datum foundations for dense multi-face fixture setups
These tooling columns are designed to build dedicated jigs quickly with standard fixture components. Full stress-relief annealing helps eliminate internal stress so the column stays dimensionally stable under heavy cutting loads. Standardized locating designs support repeat setup, while custom drilling, sizing and threaded patterns let the same family match specialized manufacturing requirements.
Rigid casting
HT250/QT500 cast iron provides stiffness and vibration damping for roughing and finishing.
Stable geometry
Annealing reduces residual stress and helps prevent long-term deformation.
Modular locating
Plain holes, precision hole locating and T-slot options support flexible fixture setup.
Custom support
Non-standard size, thread and locating patterns can be engineered around your machine.

Typical applications
Built for high-mix workholding and automated production lines
Aerospace structural parts
Rigid datum stacks for thin-walled brackets, fittings and complex surface components on 5-axis cells.
Automotive powertrain & chassis
High-density column setups for engine blocks, transmission housings, suspension arms and structural brackets.
Mold base machining
Multi-face fixture layouts for mold bases, cores, cavities and slide carriers without rebuilding setups.
Hydraulic & pneumatic housings
Repeatable workholding for valve bodies, manifolds and machined housings with tight datum control.
High-mix low-volume production
Modular columns let you swap fixture decks between jobs instead of rebuilding the entire cell.
Lights-out automation
Multi-face tombstones extend cycle length on 4/5-axis pallet, zero-point and FMS lines for unmanned shifts.

Frequently Asked Questions
What information should I provide for a tooling column quote?
Send the machine model, pallet or table interface, required column height, workpiece envelope, fixture density and preferred locating pattern. Drawings or CAD files help confirm the fastest standard or custom route.
Can these columns work with zero-point systems?
Yes. The columns can be matched to pallet systems and zero-point quick-change fixtures. The base and locating pattern should be confirmed against your receiver layout before ordering.
Are custom hole patterns available?
Yes. Custom drilling, threaded holes, precision locating patterns and non-standard sizes can be quoted according to your fixture concept and machine interface.
Which column type should I choose?
Use square or double-sided columns for straightforward dense loading, cross columns for multi-station fixture layouts, and hexagonal or octagonal columns when more fixture faces and workpiece capacity are required.
What is the difference between plain drilling, precision hole locating and T-slot locating?
Plain drilling gives the cheapest mounting holes for general fixturing. Precision hole locating uses tighter-toleranced reference bores for repeatable fixture indexing. T-slot locating supports quick clamp repositioning when the same column has to serve several different job setups.
What is the typical lead time for tooling columns?
Standard models in stock generally ship within 1–2 weeks of PO confirmation. Custom drilling, sizes or locating patterns add 3–5 weeks for engineering, casting allocation and inspection. Committed lead time is confirmed in writing once the drilling drawing is locked.
Do you supply matched fixture components for the column?
The columns are designed to assemble with standard fixture components — clamps, locating pins, support blocks and zero-point receivers. We can quote the full dedicated jig kit or just the cast column body, depending on whether you want a turnkey solution or in-house assembly.
