Introducing the key manufacturing processes, precision control, and performance testing of ball screws. Throughout the machining process of ball screws, numerous critical steps influence the final product quality. Among them, the heat treatment induction hardening process of ball screws and the pitch error compensation technology are crucial for controlling product quality and precision.

Since its establishment, Suzhou Dibite Precision Machinery Co., Ltd. has consistently prioritized building a strong reputation, which has earned the trust and long-term partnerships of its clients. Focusing on product quality as the core service for every customer, and with years of accumulation, we have tailored our product performance and suitable model choices to make our clients' lives easier.

Common rough machining methods for ball screw in China

Hard turning process

For example, a screw with a diameter of 40mm and a pitch of 6mm, the I part rotates at approximately 680 rpm, where can I find a 0804 ball screw? The characteristics of this processing method are:

Compared to the deep feed grinding process with abrasive wheels, production efficiency is increased by about 5-10 times.

2. Only 90-degree V-grooves can be cut on the workpiece. When the pitch is large, the axial cutting force is high, making it unsuitable for cutting large pitch workpieces. Generally, workpieces with a pitch of 6mm or less are machined.

3. High workpiece speed during turning, along with significant cutting resistance in hard turning, can easily cause vibration and bending deformation in slender parts, making turning operations impossible. Therefore, the turning method is suitable for machining workpieces with a length-to-diameter ratio of less than 1m and a pitch of 6mm or less.

4. Blade prices are low.

5. The threaded rod after grooving requires semi-finishing and finishing grinding.

Common processing methods for ball screw

The features of the rigid helical milling include:

1. The thread groove can be milled into shape in one operation, reducing the semi-finishing process as the workpiece can proceed directly to fine grinding.

2. The workpiece rotates at a lower speed, with multiple milling cutters mounted on the milling disk. The price of a 0601 ball screw is [insert price], and the cutters process at a speed of 180-240 m/min, offering higher production efficiency than hard turning. Compared to turning, where only one tool is involved in cutting, milling can involve up to 12 tools, significantly reducing the cutting resistance on each tool and preventing workpiece vibration and bending deformation.
