52/96mm Zero-point positioning quick-change system

Modular Tooling Fixtures	🎯Building "Rapid Changeover" Capability For any CNC workshop, one of the biggest hidden costs is "machine idle time" — the downtime when expensive machine tools stop cutting during workpiece changeovers, re-indication, and program debugging.
Advantage Dimension	Specific Benefits for CNC Workshops	How to achieve this
1. Ultra-Fast Setup Change	Reduces changeover time from hours to minutes. Enables mixed production of small batches and multiple varieties, allowing quick response to orders.	Zero-Point System: The base plate is permanently mounted on the machine table. All fixtures lock in one second via zero-point locating pins with micron-level repeatability, eliminating any need for re-indication.
2. Ultimate Precision	Eliminates human error, ensuring absolute consistency for batch processing and secondary setups, improving yield rates.	The zero-point system's extremely high repeatability (typically within 0.005mm) ensures that the workpiece coordinate system remains constant no matter how many times vises or chucks are removed and remounted.
3. Unlimited Flexibility	One machine, multiple uses. A 4-axis/5-axis machine can switch from machining aluminum to steel or precision parts in minutes, covering everything from heavy cutting to finishing.	Modular Fixture Library: Based on workpiece shape (square, round, irregular) and size, users can quickly select the optimal clamping method using self-centering vises, collet chucks, or three-jaw chucks.
4. Protects Machine Tools & Reduces Skill Dependency	Prevents damage to expensive table surfaces from frequent hammering or prying of fixtures on T-slots. Standardized setup allows less experienced operators to perform precise clamping.	Standardized Interface: All operations require only wrench tightening—no dial indicator alignment is needed. This reduces reliance on highly skilled machinists and protects the machine asset.
5. Improves Fixture ROI	Turns expensive precision vises and chucks from "dedicated tooling" into "shared assets" that can be quickly transferred between multiple machines.	By equipping each machine with just one base plate, a single set of high-quality fixtures becomes usable across all machines, amortizing the cost per part.
