Product Description

In the world of CNC machine tools, machining centers, and automated tool changing equipment, tool magazine screws stand as pivotal fasteners, crucial to the seamless operation of these sophisticated systems. These screws are vital for securing components like tool heads, tool holders, drive modules, and sensors, directly influencing the stability, precision in tool changing, and overall lifespan of the equipment. Below, we delve into a comprehensive description covering functional positioning, structural classification, technical parameters, selection criteria, common challenges, and their ingenious solutions:

The Core Functionality of the Knife Magazine Screw

1. Robust Mechanical Connection and Fixation

-In both disc and chain type tool magazines, these screws ensure a steadfast connection to the machine's body, drive motor, tool holder, and other components, safeguarding against any loosening or displacement of the tool magazine's structure, even during high-speed rotations or tool changes.

Example: Consider the fixing screws of the knife magazine motor, which must endure the instant torque during motor startup, preventing vibrations that could lead to motor displacement.

2. Unmatched Position Accuracy Guarantee

Thanks to high-precision thread matching (for example, a tolerance level of 6g/6H), these screws ensure that the positioning error of tool magazine components, such as the tool holder mounting hole and sensor bracket, remain within ≤± 0.02mm. This precision ensures the perfect alignment between the tool holder and spindle during tool swaps.

Data: The coaxiality error in high-precision tool magazine screws is kept to ≤ 0.01mm to prevent any eccentricity of the tool holder caused by tool change impacts.

3. Exceptional Fatigue Resistance and Durability

• Designed to withstand the dynamic loads from the frequent start and stop cycles of the tool magazine, which can reach an impressive 20-60 tool changes per minute, these screws prevent thread fatigue and failure.

Case Study: A particular machining center's tool magazine screws suffered thread slippage after just 3 months due to the absence of high-strength grade screws.

4. Superior Environmental Adaptability

Engineered to combat corrosion in harsh industrial settings filled with cutting fluids, cooling oils, and metal debris, these screws prevent breakages or jamming that rust might cause.

• Testing: Impressively, they show no signs of corrosion even after enduring a rigorous 72-hour salt spray test, affirming their reliability in humid environments.
