Product Core Definition

Compact High-Precision Self-Centering Zero-Point Vise with Hard Jaws is an integrated high-precision CNC fixture combining zero-point quick-change, automatic self-centering, and hardened hard-jaw clamping. It is specially designed for high-speed mass finishing of small precision parts and symmetrical components.

It solves traditional vise pain points such as:

Manual alignment errors

Time-consuming setup

Low rigidity

Inability to adapt to automated production lines

Traditional ordinary vises require manual dial indicator alignment for each clamping, resulting in long debugging time and batch dimensional deviation. Common self-centering vises lack a zero-point benchmark, requiring re-calibration after each change-over and causing long machine idle time. Soft-jaw vises suffer insufficient clamping rigidity, leading to workpiece sliding and vibration during cutting, failing to meet mass production precision requirements.

This compact zero-point self-centering vise adopts an ultra-compact integrated structure to save machine travel space, enabling multi-station dense clamping. Overall quenched hardened steel hard jaws deliver ultra-high wear resistance and clamping rigidity. The built-in synchronous self-centering mechanism ensures symmetrical jaw feeding and automatic workpiece centering without manual correction. The bottom integrated zero-point interface supports rapid docking with all standard zero-point chucks and pallets, realizing second-level quick change. It is widely applied in 3C electronics, medical precision parts, and micro mold processing, greatly improving machining efficiency and batch consistency.

Structural Design

The vise consists of the following key components:

①　Integrated stress-relieved alloy steel body

②　Synchronous self-centering transmission mechanism

③　Fully quenched hard steel jaws

④　Zero-point positioning base

⑤　ustproof sealing system

⑥　Fine locking components

The integrated compact structure eliminates redundant volume and maximizes machine effective travel. The vise body undergoes professional aging stress relief to prevent long-term deformation. Hard jaws are fully quenched and precision ground with uniform hardness and flatness for lasting clamping accuracy.

Working Principle

1. Automatic self-centering:

The internal synchronous transmission system drives dual jaws to feed symmetrically. Workpieces are automatically centered regardless of placement position, achieving micron-level centering accuracy and eliminating manual alignment errors.

2. Zero-point quick change:

The bottom standard zero-point interface locks firmly with zero-point chucks. Tooling change-over requires no re-alignment, greatly reducing machine downtime and supporting automated robot loading and unloading.

Maintenance Guidelines

1. Pre-installation cleaning: Clean the zero-point chuck surface and vise bottom datum thoroughly to eliminate chips, oil and impurities that could cause positioning deviation.

2. Mounting: Place the vise accurately on the zero-point chuck. Activate the locking mechanism and confirm firm fixation without shaking before operation.

3. Workpiece loading: Place the workpiece in the middle of the jaws arbitrarily. The dual hard jaws will automatically center and clamp symmetrically. Check clamping firmness before cutting.

4. Clamping force adjustment: Adjust clamping force according to workpiece material. Light force for thin hard workpieces; proper tightening for steel hard materials to avoid deformation or sliding.

5. Post-change-over cleaning: Clean jaw surface residues after each production change-over to prevent impurity extrusion causing workpiece deformation and positioning error.

6. Periodic maintenance: Regularly lubricate the internal synchronous transmission structure to keep feeding smooth; calibrate centering accuracy periodically.

7. Prohibited operations: Do not overload or over-stroke clamp to prevent jaw deformation and transmission structure damage.

Common Faults & Solutions

1.Fault: Inconsistent workpiece dimensional accuracy

Cause: Residual chips on jaws, transmission jamming, incomplete zero-point locking, slight jaw wear

Solution: Clean jaw surface, lubricate transmission parts, re-lock zero-point datum, replace worn jaws.
