Important Note: Always verify compatibility with your workbench or milling machine before purchase. The QM16160 is designed for industrial-grade applications—ensure your setup can support its weight and mounting requirements.
Key Factors When Choosing a QM16160 Accu Lock Machine Vice
- Size and Jaw Capacity
The size and jaw opening of the QM16160 directly determine the maximum dimensions of workpieces it can securely hold. With a standard jaw width of 160mm (approximately 6.3 inches), this vice is ideal for medium to large components commonly used in CNC milling, lathe operations, and metal fabrication.
- Check the maximum jaw opening (typically around 160mm) to ensure it accommodates your largest workpieces.
- Consider jaw height and throat depth for tall or deep parts.
- Evaluate the overall weight of the vice—cast iron models offer stability but require a sturdy mounting surface.
- Ensure the base design allows for secure bolting to your machine table or bench via T-slots or pre-drilled holes.
- Design and Jaw Types
The QM16160 Accu Lock series often features versatile jaw configurations that enhance gripping flexibility. The design impacts how well the vice handles different shapes, materials, and machining forces.
- Flat Jaws: Ideal for square or rectangular stock; provide uniform pressure distribution.
- Soft Jaws (Replaceable): Made from aluminum or mild steel, these can be machined to custom profiles for irregular or delicate parts.
- Angled or Swivel Bases: Some variants allow rotation for compound angle setups, increasing versatility in complex operations.
- Interchangeable Jaw Systems: Advanced models support quick-swap jaws for different tasks—highly recommended for production environments.
- Materials and Construction Quality
Durability and rigidity are paramount in a machine vice. The QM16160 is typically constructed from high-grade cast iron, known for its vibration-damping properties and resistance to deformation under load.
- Cast Iron Body: Offers excellent strength and stability; resists chatter during heavy cutting.
- Hardened Guide Ways: Precision-ground surfaces reduce wear and maintain alignment over time.
- Spindle and Nut Assembly: Look for alloy steel components with anti-backlash features to minimize play.
- Avoid lightweight aluminum alternatives unless working with low-force applications—they lack the rigidity needed for precision milling.
- Clamping Mechanism and Operation
The "Accu Lock" system is one of the standout features of this vice, designed for rapid, one-handed operation without sacrificing clamping force.
- Octagonal Locking Lever: Allows tool-free adjustment and secure locking with a simple turn—ideal for repetitive setups.
- Screw-Driven vs. Wedge Mechanism: The QM16160 uses a hybrid approach—fine-tuned screw control with quick-release wedge action for speed and precision.

- Precision and Accuracy
For CNC and precision machining, even minor misalignment can lead to costly errors. The QM16160 is engineered for tight tolerances and repeatable positioning.
- Look for vices with ground jaws parallel within ±0.02mm for high-accuracy work.
- Check for minimal play between the sliding jaw and body—excessive wiggle reduces repeatability.
- Some models include graduated scales or digital readouts for precise positioning.
- The base should be ground flat to ensure consistent alignment when mounted on a machine table.
- Budget, Brand Reputation, and Value
While price is important, investing in a quality machine vice like the QM16160 pays off in longevity, safety, and reduced downtime.
- Compare pricing across reputable suppliers—beware of counterfeit or off-brand clones with inferior materials.
- Brands such as Kurt, Bison, and Lang offer similar performance; however, the Accu Lock QM series provides excellent value for mid-range workshops.
- Consider long-term costs: a cheaper vice may wear faster, require frequent replacement, or compromise part accuracy.
- Look for warranties or certifications (e.g., ISO standards) as indicators of quality control.

Q3: How does a machine vice function in a machining environment?A machine vice is a fundamental tool used to securely hold workpieces during cutting, drilling, milling, or other precision operations. It functions as follows:
- Mounting: The vice is bolted or clamped onto the machine table (such as a milling machine or drill press) and precisely aligned using dial indicators or edge finders to ensure accuracy.
- Workpiece Placement: The object to be machined is positioned between the two jaws of the vice.
- Clamping: The movable jaw is tightened via a screw mechanism until the workpiece is firmly held in place without deformation.
- Protection: In many cases, soft jaw inserts or protective pads made of brass, plastic, or leather are used to prevent marring delicate surfaces while maintaining grip.
The Accu Lock system enhances this process by providing a quick-release mechanism and positive locking engagement, reducing setup time and increasing repeatability across multiple operations.
Q4: What types of Accu Lock machine vices are most commonly used?Several types of machine vices are available, each suited to specific applications. The most popular include:
- Fixed Jaw Vice: One of the most common designs, where one jaw is rigidly attached to the base. This provides maximum stability and is ideal for general-purpose machining tasks.
- Swivel Base Vice: Allows rotation of the entire vice on a graduated base, enabling angular positioning of the workpiece for complex cuts and multi-axis operations.
- Double-Acting (Adjustable) Vice: Features two moving jaws that center the workpiece automatically, improving alignment and reducing setup time. This type is especially useful for symmetrical parts.
- Power-Operated Vice: Uses hydraulic or pneumatic systems for rapid clamping in high-volume production environments, though less common in standard Accu Lock lines.
Choosing the right type depends on the machining requirements, including precision level, frequency of use, and complexity of the workpieces involved.
