Product Description

In the world of CNC machine tools, machining centers, and automated tool changing equipment, tool magazine screws are pivotal fasteners. These indispensable components securely anchor tool magazine elements such as tool heads, holders, drive modules, and sensors. The performance of these screws is crucial, as it significantly influences the stability, precision in tool changing, and longevity of the equipment. Below, we delve into the intricacies from the perspectives of functional positioning, structural classification, technical parameters, selection criteria, as well as common issues and their solutions:

The Essential Role of Knife Magazine Screws

1. Mechanical Connection and Stabilization

- The disc or chain-type tool magazine is firmly affixed to the machine tool body, drive motor, tool holder, and other components. This ensures that the overall structure remains steadfast and aligned, even during high-speed rotations or tool changes.

Illustrative Example: The screws that secure the knife magazine motor are critical. They must endure the motor's instantaneous torque upon startup, preventing any vibration-induced displacement.

2. Ensuring Position Accuracy

Employing high-precision threading (e.g., tolerance level 6g/6H) ensures that each component of the tool magazine maintains a positioning error of ≤± 0.02mm. This precision guarantees that the tool holder aligns seamlessly with the spindle during replacements.

Insightful Data: The coaxiality error for high-precision tool magazine screws should not exceed ≤ 0.01mm. This precision averts eccentricity in the tool holder due to impacts during tool changes.

3. Fatigue Resistance and Longevity

• Designed to withstand the dynamic loads from frequent start-stops of the tool magazine, which may occur at rates of up to 20-60 changes per minute, thereby preventing thread fatigue failures.

Practical Case: A known brand of machining centers experienced thread slippage in tool magazine screws within three months of use, attributable to the absence of high-strength grades.

4. Environmental Robustness

These screws must resist the corrosive effects of industrial settings—including cutting fluids, cooling oils, and metallic debris—to prevent rust-induced breakage or jamming.

• Rigorous Testing: No signs of corrosion after a stringent 72-hour salt spray test, ensuring dependability in humid environments.
