QM16N Series Precision Machine Vice – High Accuracy Zero-Lift CNC Milling Vise

Description

The QM16N Series Precision Machine Vice is a premium-grade workholding solution specifically engineered for high-accuracy milling, grinding, drilling, EDM, and CNC machining applications. Constructed from high-quality alloy steel and fully hardened for maximum wear resistance, the vise incorporates a precision angle-lock mechanism that converts clamping force into simultaneous downward pressure, eliminating workpiece lifting during machining. All critical surfaces are precision ground to ensure superior flatness, squareness, and parallelism, making the QM16N Series an ideal choice for toolrooms, mold manufacturers, precision engineering workshops, and production machining environments where repeatable accuracy is essential.

Patented 45° Downward Force Anti-Lift Clamping System

The internal angle-lock mechanism generates a 45° downward force during tightening, pressing the workpiece firmly against the vise bed while simultaneously applying horizontal clamping pressure. This eliminates workpiece lifting commonly encountered in conventional vises and significantly improves machining accuracy, surface finish quality, and dimensional consistency during both roughing and finishing operations.

Hardened Alloy Steel Construction for Long-Term Accuracy

The vise body, fixed jaw, and movable jaw are manufactured from premium alloy steel and undergo heat treatment to achieve high hardness and excellent wear resistance. This hardened construction maintains geometric accuracy over years of continuous industrial use and provides exceptional durability in demanding machining environments.

Precision Ground Working Surfaces

All guideways, jaw faces, base surfaces, and reference planes are precision ground to tight tolerances. The resulting high degree of flatness and parallelism ensures smooth jaw travel, precise workpiece positioning, and excellent repeatability during batch production and precision machining applications.

Compact Low-Profile Design for Maximum Machine Accessibility

The low-profile body design minimizes interference between the vise and cutting tools, allowing greater spindle access and improved machining flexibility. This configuration is particularly beneficial when machining complex components requiring multiple tool approaches and deep cavity operations.

High Rigidity Structure for Precision CNC Machining

The one-piece precision-machined body provides outstanding structural rigidity and vibration resistance. The robust design minimizes deflection under heavy cutting loads and helps maintain dimensional stability throughout extended machining cycles, making the vise suitable for both high-speed machining and precision finishing operations.

Excellent Repeatability for Production Environments

The precision lead screw and guide system ensure smooth jaw movement and consistent clamping force over repeated cycles. Operators can achieve highly repeatable setups with minimal adjustment, improving productivity and reducing setup times in production machining environments.

Available in Two Precision Models

The QM16N Series is offered in two standard specifications to accommodate different machining requirements. Both models provide the same high-precision construction, anti-lift clamping technology, and hardened alloy steel durability while covering a broad range of workpiece sizes.
