Product Description

Tool magazine screws are indispensable fasteners in CNC machine tools, machining centers, or automated tool-changing equipment. These screws ensure the secure fastening of critical components such as tool heads, tool holders, drive modules, and sensors. Their performance is pivotal, influencing the stability, precision in tool changes, and extended equipment lifespan. Below is a comprehensive insight into their significance from the perspectives of functional positioning, structural classification, technical parameters, selection criteria, common challenges, and corresponding solutions:

The Essential Role of Knife Magazine Screws

1. Mechanical Connection and Stabilization

- The disc/chain type tool magazine is firmly anchored to the machine tool body, drive motor, and tool holder, among other components. This robust connection ensures that the tool magazine maintains its structural integrity, avoiding any loosening or misalignment during high-speed maneuvers or tool swaps.

Example: The fixing screws of the knife magazine motor need to endure the instantaneous torque upon motor activation, thus preventing vibrations that might cause motor displacement.

2. Precision in Positioning Accuracy

High-precision threading (such as tolerance level 6g/6H) is employed to ensure each component of the tool magazine, like the tool holder mounting hole and sensor bracket, achieves a positioning error of ≤± 0.02mm. This precision is critical for accurate alignment between the tool holder and spindle during tool changes.

Data: High-precision tool magazine screws should boast a coaxiality error ≤ 0.01mm to mitigate tool holder eccentricity due to impact during tool swapping.

3. Fatigue Resistance and Longevity

• These screws must withstand the dynamic load of frequent tool magazine start-stops, which can reach up to 20-60 tool changes per minute, to avoid thread fatigue failure.

Case: A particular machining center brand experienced thread slippage in tool magazine screws after just 3 months of use due to the absence of high-strength grades.

4. Environmental Resilience

These screws must combat corrosion from industrial environments, including cutting fluid, cooling oil, and metal debris, to prevent breakage or jamming from rust.

• Testing: After enduring a 72-hour salt spray test without corrosion, these screws demonstrate their reliability in humid conditions.
