Product Description

Tool magazine screws are the essential fasteners for CNC machines, machining centers, and automated tool exchangers. They are pivotal in securing critical components like tool heads, holders, drive modules, and sensors. The efficacy of these screws profoundly influences the stability, tool-swapping precision, and longevity of the tool magazine. Below, we delve into their roles from several perspectives: functional positioning, structural classification, technical specifications, selection criteria, and troubleshooting with tailored solutions:

The Core Functions of the Knife Magazine Screw

1. Mechanical Connection and Fixation

- The robust disc/chain tool magazine securely interfaces with the machine's body, drive motor, tool holder, and other elements, ensuring unwavering structural integrity during high-speed operations or tool exchanges.

Example: The fixing screws of the knife magazine motor must endure the motor's startup torque to prevent vibrations causing motor displacement.

2. Position Accuracy Assurance

With high-precision threading (tolerance level 6g/6H), the tool magazine components' positioning errors (e.g., tool holder mounting holes or sensor brackets) are kept within ± 0.02mm, guaranteeing flawless alignment between tool holder and spindle during replacements.

Data: Coaxiality errors in precision tool magazine screws should be ≤ 0.01mm to prevent eccentricity issues during tool changes.

3. Fatigue Resistance and Durability

• Withstand the dynamic stresses from frequent tool magazine start-stops (up to 20-60 changes per minute) to avert thread fatigue and failure.

Case: A machining center brand encountered thread slippage in tool magazine screws after 3 months of use due to inadequate strength grades.

4. Environmental Adaptability

Withstand corrosion from harsh industrial conditions, including cutting fluids, cooling oils, and metal debris, preventing rust-induced breakage or jamming.

• Testing: Achieved no corrosion after a rigorous 72-hour salt spray test, ensuring reliability in moist environments.
