Zhuxinde CNC external cylindrical grinding high-precision ball screw

The grinder screw is the core transmission component of the grinder, mainly used to accurately convert the rotational motion of the motor into linear motion of the worktable or grinding wheel holder, directly determining the machining accuracy, feed sensitivity, and operational stability of the grinder.

Specific function

• Precision motion control

• The screw achieves micrometer or even nanometer level linear displacement by cooperating with the nut (such as the rolling friction structure of a ball screw), ensuring the positioning accuracy and surface quality of the workpiece12.

• In CNC grinding machines, the transmission accuracy of the screw directly affects the accuracy of complex machining such as thread grinding and external cylindrical grinding.

• High rigidity and stability

• The screw structure (such as full nut or double nut design) can provide high rigidity support, avoid deformation under load, ensure the smoothness of feed motion, and reduce vibration and crawling phenomena4.

• For example, the double nut pre tightening structure can eliminate axial clearance, improve transmission stiffness, and make the feed of the grinding wheel frame more accurate5.

• Efficient Transmission and Automation

• The friction resistance of ball screw is small, the transmission efficiency is high (the driving torque is reduced to 1/3 compared to sliding screw), reducing energy consumption and thermal deformation, and adapting to high-speed and heavy-duty automated processing scenarios26.

• Cooperate with CNC system to achieve automatic feed and real-time error correction, improve production efficiencyGap elimination and precision maintenance

• By adjusting the pre tightening force (such as pre tightening with double nut washers or eliminating gaps with springs), wear can be compensated for and transmission accuracy can be maintained for a long time5.
