Pain Point Analysis

Extended Travel Self-Centering Zero-Point Vise with Soft Jaws is a newly upgraded high-performance zero-point fixture specially developed for:

①　Large-size workpieces

②　Thin-wall soft workpieces

③　Special-shaped non-standard parts

Industry pain points this product solves:

1. Traditional standard-stroke zero-point vises are limited in clamping range and easily scratch or deform soft workpieces with hard jaws.

2. Ordinary long-stroke clamps lack automatic centering function, relying entirely on manual alignment and dial indicator calibration, resulting in long setup time and inconsistent batch dimensional accuracy.

3. Most common long-stroke fixtures have no zero-point quick-change interface, unable to adapt to FMS automated production lines, causing long machine idle time and low processing efficiency.

Our solution:

This Extended Travel Self-Centering Zero Point Vise with Soft Jaws completely solves the above industry pain points:

The extended clamping stroke greatly expands the adaptable workpiece size, covering long strip parts, wide thin plates, and special-shaped frame parts.

Flexible soft jaws avoid surface indentation and extrusion deformation.

The built-in high-precision synchronous self-centering mechanism realizes automatic workpiece centering without manual correction.

The integrated zero-point base supports fast switching and robot automatic loading and unloading.

Featuring large clamping range, high precision, no damage, and easy maintenance, it is widely used in new energy accessories, aerospace aluminum parts, 3C structural parts, and medical precision parts processing, becoming a hot-sale upgraded fixture for modern precision machining workshops.

Structural Composition

The vise is composed of the following key components:

①　Integrated cast steel body

②　Extended synchronous transmission mechanism

③　Replaceable flexible soft jaws

④　Zero-point positioning base

⑤　Fully enclosed dust-proof and waterproof components

⑥　Fine-tuning locking device

Body treatment: The vise body undergoes multiple stress relief treatments to eliminate internal processing stress, ensuring no long-term deformation under high-frequency clamping.

Transmission system: The extended rack-and-pinion transmission group is precisely matched with tiny transmission gaps to ensure synchronous feeding of double jaws.

Jaw design: High-toughness soft jaws can be polished and modified to fit special-shaped curved workpieces.

Sealing: The fully sealed structure effectively isolates chips, coolant, and dust, adapting to harsh machining environments.

Working principles

1. Synchronous self-centering clamping:

The internal extended transmission system drives symmetrical feeding of double soft jaws. Workpieces are automatically centered regardless of placement position, eliminating manual alignment errors and ensuring batch dimensional consistency. The flexible contact structure disperses clamping pressure and prevents thin-wall workpiece deformation and surface damage.

2. Zero-point quick-change positioning:

The bottom standard zero-point interface locks with mainstream zero-point chucks and pallets to achieve micron-level repeated positioning accuracy. Tool change-over requires no re-calibration, realizing second-level fast replacement, greatly reducing machine downtime and adapting to automated unmanned production.

Core Product Advantages

1. Extended travel design for wider compatibility.

The upgraded long clamping stroke solves the limitation of traditional short-stroke vises, supporting large-size strip and wide thin-plate workpieces, reducing fixture procurement costs.

2. Damage-free flexible soft-jaw clamping.

Uniform pressure dispersion avoids surface indentation, extrusion deformation, and edge damage of soft precision workpieces, greatly improving product yield.

3. Micron-level automatic self-centering system.

Synchronous feeding ensures ultra-high centering accuracy without manual calibration, completely eliminating human operation errors and ensuring stable batch processing quality.

4. Standard zero-point quick-change structure.

Plug-and-play design shortens tool change time, compatible with manual and FMS automated production lines, improving machine utilization rate.

5. Fully sealed protective structure.

Isolates workshop impurities to prevent transmission jamming and precision attenuation, delivering durable performance and low maintenance frequency.

6. Customizable replaceable soft jaws.

Jaws can be polished for special-shaped curved workpieces. Custom size and radian jaws support special non-standard working conditions with strong universality.

7. Stable stress-relieved body.

No deformation under long-term high-frequency clamping, maintaining long-term precision stability and longer service life than ordinary vises.

Application Scenarios

1. New energy precision parts processing: Thin-wall aluminum shells, connecting profiles, and long strip structural parts achieve deformation-free high-precision batch processing.

2. 3C electronic structural parts: Thin-wall aluminum and copper components and frame parts realize efficient and consistent mass production.

3. Aerospace lightweight parts: High-precision damage-free clamping for aviation aluminum thin-wall components meets aerospace processing standards.

4. Mold auxiliary parts machining: Frequent change-over of special-shaped mold inserts reduces debugging time and improves production efficiency.

5. 5-axis machine precision machining: Extended travel avoids stroke interference, adapting to multi-angle curved surface processing of 5-axis equipment.

6. FMS flexible automated lines: Cooperates with robot automatic loading and unloading to realize unmanned continuous high-efficiency production.

7. Standard Installation & Debugging Process

8. Pre-installation cleaning: Clean the zero-point chuck and vise bottom datum completely to remove chips, oil, and dust, avoiding positioning deviation.

9. Mounting: Align the vise with the zero-point chuck, activate the locking mechanism, and confirm firm fixation without shaking.

10. Workpiece loading: Place the workpiece casually in the middle of jaws. Adjust clamping force moderately according to workpiece material to avoid deformation or sliding.

11. Test run: Run the machine after clamping to ensure stable workpiece fixation without vibration or displacement.

12. Automation calibration: Calibrate robot grabbing points for automated production to ensure accurate docking and avoid structural impact damage.

Daily Maintenance Rules

Pre-operation cleaning: Clean jaw surface impurities before daily work to ensure flat clamping contact.

Regular lubrication: Lubricate the internal synchronous transmission structure regularly to keep feeding smooth.

Jaw care: Avoid violent knocking or over-polishing of soft jaws. Replace worn jaws in time.

Datum protection: Protect the zero-point datum surface from collision and rust to maintain long-term precision.

No overloading: Do not overload or over-stroke clamp to prevent transmission structural deformation.
