Product Description

Tool magazine screws are key fasteners used in CNC machine tools, machining centers, or automated tool changing equipment to secure tool magazine components such as tool heads, tool holders, drive modules, sensors, etc. Their performance directly affects the stability, tool changing accuracy, and equipment lifespan of the tool magazine. The following is a description from the dimensions of functional positioning, structural classification, technical parameters, selection points, common problems, and solutions:

The core function of the knife magazine screw

1. Mechanical connection and fixation

-The disc/chain type tool magazine is rigidly connected to the machine tool body, drive motor, tool holder and other components to ensure that the overall structure of the tool magazine is not loose or offset during high-speed rotation or tool change.

Example: The fixing screws of the knife magazine motor need to withstand the instantaneous torque when the motor starts, to avoid vibration causing motor displacement.

2. Position accuracy guarantee

By using high-precision thread matching (such as tolerance level 6g/6H), the positioning error of each component of the tool magazine (such as the tool holder mounting hole and sensor bracket) is ensured to be ≤± 0.02mm, ensuring precise alignment between the tool holder and the spindle during tool replacement.

Data: The coaxiality error of high-precision tool magazine screws should be ≤ 0.01mm to avoid tool holder eccentricity caused by tool change impact.

3. Fatigue resistance and durability

• Bear the dynamic load generated by frequent start stop of the tool magazine (up to 20-60 tool changes per minute) to avoid thread fatigue failure.

Case: A certain brand of machining center's tool magazine screws experienced thread slippage after 3 months of operation due to not using high-strength grades.

4. Environmental adaptability

Resist corrosion from industrial environments such as cutting fluid, cooling oil, and metal debris to prevent screw breakage or jamming caused by rust.

• Testing: No corrosion after 72 hours of salt spray test, ensuring reliability in humid environments.
