The abrasive blasting machine drive disc (also known as the impeller connection disc or the main shaft disc) is a key component for power transmission in the abrasive blasting unit. It is installed at the end of the motor's main shaft and is connected to the center disc (the impeller body) through precise positioning and locking mechanisms, fulfilling the crucial mission of transmitting the high-speed torque from the motor to the core components of the abrasive blasting system in a complete and smooth manner.

Precision dynamic balancing process: Each drive disc undergoes strict G2.5 level dynamic balancing verification. Even under operating conditions of up to 2900 revolutions per minute, it can maintain extremely low vibration levels, effectively preventing early wear of the motor bearings due to uneven force distribution. High-toughness alloy steel material: High-quality 40Cr or 35CrMo alloy steel is selected and undergoes overall quenching and tempering heat treatment. Compared to ordinary cast steel parts, its torsional strength and fatigue limit increase by more than 30%, completely eliminating the risk of cracking under high-speed operation. CNC precision machining: The shaft holes and end faces are machined in one go using a CNC lathe to ensure that the verticality and coaxiality tolerances are controlled at the micron level, making installation smoother and operation quieter. Standard compatibility: A wide range of specifications are available, perfectly compatible with mainstream abrasive blasting machine models both domestically and internationally, and supports custom non-standard sizes based on drawings.
