5th Axis Product Categories

The company manufactures a broad range of machining solutions.

Self-Centering Vises

One of the company's best-known products is the self-centering vise.

Unlike traditional vises that move one jaw, self-centering vises move both jaws equally toward the center.

Benefits include:

Improved part centering
Faster setup
Excellent repeatability
Reduced programming adjustments
Better compatibility with multi-axis machining

These vises are especially useful for precision production environments.

RockLock Workholding System

The RockLock system is a modular workholding platform that allows machinists to rapidly change fixtures while maintaining highly repeatable positioning.

Advantages include:

Fast fixture changes
Accurate repeatability
Improved spindle uptime
Reduced setup labor
Better workflow efficiency

RockLock systems are commonly integrated into production machining environments.

Fixture Plates

Fixture plates provide a stable foundation for mounting vises, clamps, and custom fixtures.

Benefits include:

Consistent locating
Flexible workholding
Easy fixture changes
Improved production efficiency

Fixture plates are available in multiple sizes to accommodate various machining centers.

CNC Tombstones

Tombstones are multi-sided fixtures commonly used on horizontal machining centers.

Benefits include:

Multiple work offsets
Increased production capacity
Reduced machine downtime
Continuous machining

By holding several parts simultaneously, tombstones help maximize spindle utilization.

Rotary Workholding

Rotary workholding systems support advanced machining operations using 4-axis and 5-axis equipment.

Advantages include:

Multi-sided machining
Fewer setups
Better part access
Reduced handling
Improved accuracy

These systems are commonly used for complex aerospace, medical, and precision-machined components.

Applications

5th Axis workholding products are used across numerous industries.

Common applications include:

Aerospace manufacturing
