96 Quick Change Fixture Plate for CNC Workholding

This high-performance 96 Quick Change Fixture Plate for CNC Workholding is manufactured from premium 42CrMo hardened alloy steel, featuring outstanding repeat-positioning accuracy, ultra-robust structural rigidity and long-term stable mechanical performance. All key positioning reference surfaces adopt strict one-clamping integral machining technology to ensure high overall datum consistency. After rough machining, the alloy-steel blanks undergo complete stress-relieving aging treatment to thoroughly eliminate internal residual stress and avoid structural deformation caused by long-term alternating cutting loads.

Critical mating surfaces — the bottom locating face that sits on the 96 chucks and the top workpiece-mounting datum — are finished by ultra-precision grinding, delivering stable and reliable mating performance. Supporting offline fixture presetting and rapid on-machine locking/swapping, it effectively reduces manual alignment workload, shortens fixture setup time and lowers non-cutting downtime. Widely applicable to mold processing, multi-axis precision milling and automated production lines, it provides a solid, standardized and high-efficiency modular clamping platform for global industrial machining workshops.

Why Choose JWGRIP

Conventional fixture plates create many troubles in daily mold and multi-axis machining workshops:

· Frequent fixture replacement requires repeated installation, alignment and manual calibration. Setup quality heavily depends on operator skill, yielding unstable positioning results and wasting valid production hours.

· Homemade ordinary fixture plates lack a standardized pull-stud pattern and datum machining. Sustained alternating cutting loads produce stress concentration and subtle plate deformation, gradually ruining positioning accuracy and batch-part dimensional consistency.

JWGRIP improves the product from raw-material processing to finished-part grinding:

All critical positioning reference surfaces adopt one-clamping complete-machining strategy.

Hardened 42CrMo alloy-steel blanks go through full stress-relief aging after rough machining to remove internal residual stress.

The bottom locating face and top workpiece datum are precision-ground to secure stable seating on 96-series zero-point chucks.

The standard 96-series pull-stud pattern enables offline fixture presetting. Operators build vises and sub-fixtures on the plate outside the machine; the complete plate is then seated onto the 96 chucks and locked in seconds, cutting manual alignment workload.

Custom & OEM services support special-size workpieces and unique machine-table installation needs, offering a reliable modular clamping platform for mold processing, multi-axis precision milling and automated production lines.

Core Mechanism

The JWGRIP 96 Quick Change Fixture Plate is the upper tooling plate that mates with 96-series zero-point chucks mounted on the machine table:

The bottom locating face conforms to the 96-series zero-point pattern. Tapped holes on the bottom receive matched 96-pattern pull studs, which screw in from below and engage the internal clamping collets of the 96 chucks.

The bottom locating surface sits flat on the chuck reference faces; once the chucks clamp, the whole plate is pulled down and radially/axially located on one repeated-positioning datum.

The top surface uses an industry-standard grid layout of threaded holes and dowel-pin holes for mounting vises, sub-fixtures or workpieces directly.

Side datum edges are precision-milled for on-machine edge-finding and repeat loading.

Key mechanical design highlights:

All positioning reference points — bottom locating face, pull-stud hole pattern and top datum — are machined on a single plate body. Assembled spacer parts are minimized to avoid accumulated tolerance drift during repeated swap cycles.

The reinforced pocketed/ribbed structure spreads dynamic cutting force over the whole plate instead of concentrating stress on local pull-stud holes, improving durability under heavy-cutting conditions.

Locating reliability stays stable for continuous shift-based production, whether used for tender-procurement workshop projects or high-frequency changeover sites.

Technical Performances

Stable repeat-positioning accuracy: Critical datum surfaces receive multi-pass precision grinding. Repeat-positioning accuracy ≤0.010 mm after hundreds of fixture swaps. Position tolerance of the pull-stud hole pattern is strictly controlled within ±0.006 mm to prevent cumulative positioning deviation in multi-setup part machining.

42CrMo high-strength hardened alloy-steel body: Integral quenching & tempering heat-treatment delivers surface hardness HRC 54–58. Good anti-impact and anti-deformation performance resists chip scratch, cyclic clamping pressure and intermittent heavy-cutting load. Widely adopted by mold workshops, auto-component factories and aerospace processing plants.

Obvious tooling-change efficiency gain: After the 96 chucks are one-time installed on the machine table, a fixture-plate swap takes only 8–12 seconds. No repeated dial-indicator tramming is needed. Non-productive setup time drops significantly, lifting overall equipment effectiveness both for mass production and for prototype orders with frequent changeover.

Broad compatibility plus custom-OEM support: The standard pull-stud pattern fits mainstream commercial 96-series zero-point chucks. The top grid layout accommodates standard vises, sub-plates and locating jigs. The JWGRIP factory provides OEM & custom service: outer dimensions, grid hole layout, pull-stud pattern, avoidance cut-outs and mounting-boss height can all be adjusted. Customized versions satisfy special demands for tender-procurement projects and automation-line transformation.

Complete industrial certification & batch inspection: Every batch undergoes dimension check, hardness test, flatness/parallelism inspection and positioning-stability verification. ISO9001 inspection reports can be provided for tender-procurement formal-document submission.

Production & Quality-control

All JWGRIP 96 Quick Change Fixture Plate for CNC Workholding is manufactured and inspected inside our Chinese factory following a standardized multi-phase workflow:

1. Raw-material incoming inspection: 42CrMo steel bar goes through chemical-composition analysis and hardness test; material certificates attached. Unqualified raw materials are rejected directly.

2. Rough CNC milling: rough-machine outer contour, pocket/rib structure and pre-holes; leave finishing allowance on all positioning-related surfaces.

3. Quenching & tempering heat-treatment: precisely control heating, holding and cooling curves to reach HRC 54–58 target hardness and release internal material stress. This step is mandatory for anti-deformation performance under long-term dynamic cutting.

4. Stress-relief aging: further release residual stress introduced by rough machining and heat-treatment.

5. Finish CNC machining: machine the bottom pull-stud tapped holes, bottom locating face, top grid holes, side datum edges and auxiliary features; critical dimension tolerance controlled within ±0.007–0.012 mm.

6. Multi-run precision surface grinding of the top and bottom datum planes to guarantee flatness and parallelism.

7. Thread-gauge verification and pull-stud mounting simulation: confirm every tapped hole mates with the matched 96-pattern pull stud without interference.

8. Final comprehensive inspection: dimension, hardness, flatness, parallelism, pull-stud hole-position accuracy and repeat-positioning performance on a 96 chuck. Each product receives a unique traceability serial number. Non-conforming plates go for rework rather than packaging.

9. Anti-rust cleaning, black-oxide surface treatment and shock-resistant plywood-case packaging.

Mis-operation Risks

When deploying the JWGRIP 96 Quick Change Fixture Plate, watch these misuse points to avoid equipment crash or positioning failure:

Evaluate overall height in advance. The combined height of the fixture plate plus upper vises/sub-fixtures may trigger spindle crash. Run simulation measurement before formal mass cutting.

Distinguish static bearing capacity from dynamic cutting load. Even with a high static-pressure test value, users must follow the official rated dynamic-load parameters under real cutting impact.

Prevent chip accumulation on the bottom locating face and inside the pull-stud tapped holes. Iron-chip residues scratch the locating face and create positioning deviation. Implement regular on-site cleaning maintenance.

Tighten pull studs only to the specified torque. Over-torque distorts the tapped holes and plate datum; under-torque loosens under cutting vibration.

For tender-procurement projects: confirm certification format, inspection-report content and serial-number traceability requirements at the early communication phase.

Packaging

Every JWGRIP fixture plate goes through complete cleaning, anti-rust-oil spraying and anti-rust-paper wrapping, then is packed into a foam-filled shock-resistant plywood wooden case to avoid collision and vibration damage during sea freight, air freight or land transport.
