Original Yamaha Nozzle Shaft KHY-M7106-00 for YS12 / YS24 / YG12F SMT Pick and

The Yamaha Nozzle Shaft KHY-M7106-00 is an original high-precision mechanical component designed for Yamaha SMT pick and place machines, including YS12, YS24 and YG12F models. This part is a critical element of the nozzle system and is responsible for connecting, fixing, and positioning the nozzle during high-speed component placement.

In overseas markets, this part is most commonly referred to as a Nozzle Shaft. In some technical documents, it may also appear as Nozzle Stem or Ball Spline, but the function is the same: it is the core mechanical axis component of the nozzle assembly.

Unlike electronic spare parts such as control boards or sensors, the nozzle shaft is a pure mechanical precision part. Its performance directly determines the coaxial alignment, vacuum transmission efficiency, placement accuracy, and mechanical stability of the entire placement head.

In modern SMT production, placement accuracy is not determined by software alone. It is the result of a complete mechanical precision chain, including:

• Placement head structure
• Nozzle shaft
• Nozzle holder
• Nozzle tip
• Vacuum system

Among these components, the KHY-M7106-00 nozzle shaft acts as the mechanical reference axis of the whole nozzle system.

In Yamaha YS and YG series machines, the nozzle shaft functions as the structural bridge between the placement head and the nozzle tip. It ensures that the nozzle is always positioned in the correct mechanical location and maintains stable alignment during high-speed motion.

The main responsibilities of the nozzle shaft include:

• Accurately positioning the nozzle
• Maintaining coaxial alignment
• Transmitting vacuum efficiently
• Providing mechanical rigidity
• Absorbing micro-vibrations generated during Z-axis movement

If the nozzle shaft becomes worn, deformed, or contaminated, even the most advanced vision system cannot compensate for the resulting mechanical errors.

The nozzle shaft securely locks the nozzle into the placement head, preventing rotation, tilt, or axial displacement during operation.

The nozzle shaft defines the mechanical axis of the nozzle. This is especially critical for fine-pitch components such as QFNs, BGAs, and micro-size chips.

The internal structure of the nozzle shaft acts as a vacuum channel, ensuring stable suction force from the vacuum system to the nozzle tip.

The nozzle shaft absorbs micro-vibrations caused by rapid acceleration and deceleration of the placement head, improving placement repeatability.

These issues cannot be solved by software calibration or vision adjustment. In most real production cases, replacing the nozzle shaft is the only effective solution.

The nozzle tip is a consumable part, but the nozzle shaft determines the mechanical accuracy of the entire nozzle system.

The KHY-M7106-00 nozzle shaft is widely used in:
