Product Introduction
Ball Screw for Milling Machine is a precision transmission component. It is widely used on X, Y, and Z axes of CNC milling machines and machining centers.
Key Features
- Low Backlash Design
Our advanced ball circulation system minimizes backlash, delivering smoother and more precise tool movement during cutting operations. This creates uniform cutting patterns that enhance the surface finish quality of your machined components.
- High Mechanical Efficiency
Achieve mechanical efficiency of up to 90%+ with our advanced ball screw system, which reduces power loss and heat generation compared to traditional lead screws.
- Stable Feed Motion
Our rolling ball design eliminates stick-slip motion, delivering stable and uniform feed rates for consistent cutting performance that is perfectly suited for high-speed milling and complex tool path execution.

FAQ
Q: How Does a Ball Screw Work in a Milling Machine?
A: In a CNC milling machine, the ball screw connects the servo motor to the machine table or spindle axis. When the motor rotates, the ball screw converts rotational motion into linear movement through recirculating balls between the screw shaft and the nut. This rolling contact mechanism minimizes friction, eliminates stick-slip, reduces backlash, and ensures precise positioning with smooth feed.
Q: What does the DLY ball screw offer for CNC milling machines?
A: The DLY ball screw provides precise positioning, smooth feed motion, and long-term stability for X, Y, and Z axis systems in both new and retrofit CNC milling machines. As a factory-direct manufacturer with over 20 years of experience, DLY ensures reliable, high-quality linear motion solutions.
Q: How does DLY ensure product quality?
A: DLY implements strict quality control measures throughout the manufacturing process, including precision cold-rolling, surface hardening treatment, and comprehensive inspection of lead error, hardness, surface finish, and runout to meet industrial CNC standards.
