As a professional manufacturer of zero point positioning systems, JWGRIP provides in-house R&D for customized pallets, chucks and automation fixtures. The System is a high-precision modular workholding solution specially engineered for modern CNC machining workshops, automated production lines and intelligent manufacturing scenarios. In addition, we also offer Quick Change Workholding System and R-Type EDM Workholding System. Please come and consult if you are interested!
It combines zero point pallets, clamping chucks, locating pins and pull studs to reliably bring every workpiece, fixture and auxiliary tooling back to the identical fixed reference point on the machine table. Many factory operators still spend massive time on manual alignment, edge-finding, dial-indicator calibration and repeated zero-setting before each machining task, which greatly eats into effective machining hours.
With a mature zero-point positioning setup, instead of aligning each job manually, operators simply push the pallet onto the chuck, and the system centers, clamps and locks automatically, cutting changeover time from dozens of minutes to mere seconds while delivering outstanding repeatability usually within ±0.005 mm. This kind of consistent positioning performance effectively eliminates cumulative manual operation errors and lowers the risk of defective products caused by inaccurate clamping.
Quick Summary: The JWGRIP Zero Point Positioning System is a modular workholding platform that combines pallets, chucks, locating pins and pull studs into one repeatable reference system. It delivers repeatability within ±0.005 mm, cuts changeover from tens of minutes to seconds, and supports manual CNC machines, 5-axis centers, EDM workholding and robot-automated production lines. Core series include the Zero Point Pallet Series, Zero Point Clamping Chuck Series and UPC Zero Point Positioning Series.
How does it work?
Zero Point Positioning System relies on high-precision taper or sphere coupling combined with powerful, stable clamping force.
Pneumatic or hydraulic pressure drives the zero point clamping chuck to lock the locating elements tightly, forming a rigid and vibration-resistant connection between the fixture and the machine table.
Hardened, precision-ground metal contact surfaces ensure stable datum performance even under long-term heavy-cutting conditions.
Once locked, the pallet or fixture cannot shift or drift during high-speed milling, drilling or five-axis simultaneous processing. The result is fast, fool-proof changeover with consistent positioning accuracy, an ideal foundation for mass batch production, small-batch multi-variety machining, and fully automated cells equipped with robot loading and unloading devices.
Operators can swap out finished workpieces and load new pre-fixtured pallets outside the machine, without occupying valuable machine operating space.
Core Advantage
Genelogical Classification
Our Zero Point Positioning System family covers three complete series for different production requirements.
Zero Point Pallet Series
The Zero Point Pallet Series, including the Automated Zero Point Pallet with Power Chuck and the Four Center Zero Point Pallet for CNC Fixture, is ideal for quick job change and automatic production lines. You can match different pallets according to workpiece dimensions to realize flexible fixture combination.
Zero Point Clamping Chuck Series
The Zero Point Clamping Chuck series, including the Single Center Zero Point Positioning Chuck and the Six Position Zero Point Clamping Plate, is the clamping core mounted on machine tables and fixture bases, supporting multi-station simultaneous clamping to process multiple workpieces in one single cycle.
UPC Zero Point Positioning Series
The UPC Zero Point Positioning Series, including the UPC Magnetic Zero Point Pallet and the UPC Hinge Linkage Arm for Robot Quick Change Tool Changer, is built for robotic tool changing and flexible automation, perfectly cooperating with robot arms to realize unmanned pallet handling and replacement.
Application Scenarios
It is widely used in CNC milling, 5-axis machining, drilling and tapping centers, EDM workholding, grinding fixtures, robotic material handling and automated production lines. Whether you are improving an existing machine or building a new smart factory, integrating a zero point positioning system is one of the fastest ways to increase productivity. It works great for automotive parts, mold manufacturing, aerospace component processing and general precision machinery workshops.

Frequently Asked Questions
Q1: What is a zero point positioning system used for?
A: It is a modular workholding platform that brings every workpiece, fixture and tooling back to the same fixed reference point on the machine table, eliminating manual alignment and repeated zero-setting before each job.
Q2: What repeatability can I expect?
A: JWGRIP zero point positioning systems typically deliver repeatability within ±0.005 mm, depending on the series and the condition of the locating elements.
Q3: Can it be retrofitted to an existing CNC machine?
A: Yes. The system is designed as a modular platform. Existing CNC milling machines, 5-axis centers and EDM machines can be retrofitted by mounting a zero point clamping chuck on the machine table or fixture base.
Q4: Which series should I choose for a robot-automated production line?
A: For robot-integrated lines, the pneumatically controlled UPC Zero Point Positioning Series is the recommended choice. It is built for robotic tool changing and flexible automation, and cooperates with robot arms for unmanned pallet handling and replacement.
