ML-430 CNC Lathe for Ball Turning: A Dedicated Sphere-Turning Solution
In precision manufacturing, demand for perfect spherical parts is growing fast — from critical steering components in cars to medical implants, the requirement for absolute roundness is stricter than ever. The ML-430 CNC lathe from Ingenious Machinery (formerly YDPM), built in Taichung, Taiwan, is engineered specifically for high-precision ball turning. Its unique B-axis swiveling tool post and gang-type tooling layout make sphere turning not just possible, but efficient and repeatable in volume production.
360° B-Axis Swiveling Tool Post for Sphere Turning
The core innovation of the ML-430 is its specialized B-axis swiveling tool post. Unlike traditional lathes that rely solely on X/Z-axis interpolation to cut curves, the ML-430’s B-axis offers full 360° rotation, the key to true ball-turning capability.
• Precision drive: FANUC β8 (1.2 kW) servo motor for smooth, accurate rotation.
• Superior finish: Combined with a diamond roller burnishing tool, produces spheres with a mirror-like surface finish and near-perfect roundness.
• Capacity: Machines spherical workpieces up to Ø60 mm in diameter.
ML-430 Specifications: Spindle, Travel & Rapid Traverse
To support high-precision dynamic machining, the ML-430 is built on robust specifications:
• Spindle power: FANUC 5.5 / 7.5 kW spindle motor, up to 6,000 rpm. With an A2-5 nose and 6-inch chuck, it delivers stable cutting torque.
• Speed & agility: 350 mm travel in X, 320 mm in Z, driven by FANUC 1.2 kW servo motors, achieving a 30 m/min rapid traverse rate.
• Versatile tooling: Beyond the sphere-turning B-axis, supports gang-type tooling or optional live turrets (such as the LS-120SP) for drilling, tapping, and milling.
Ball-Turning Applications Across Industries
The sphere-turning capability of the ML-430 makes it a strong performer in several high-end sectors:
• Automotive: Tie rod ends and ball joints for steering systems.
• Industrial valves: Ball valves and bearing components.
• Medical: Bone screws, artificial joints, and other biomedical parts requiring ultra-smooth surfaces.
• General precision: Plungers and other complex spherical components.
Automation for Unattended Ball-Turning Production
Ready for mass production? The ML-430 comes with intelligent support systems:
• Automation options: Automatic door opening, parts catchers, and spindle air blow for cleaning.
• Cooling & chip management: Standard 150 L coolant tank with high-efficiency flushing; optional rear chip conveyor maintains thermal stability during long runs.
• Measurement: Compatible with Renishaw HPMA automatic tool setters to monitor tool condition in real time.
FAQ
Q: What is ball turning (sphere turning)?
A: Ball turning is a lathe operation that produces precise spherical surfaces. On the ML-430 it is achieved with a 360-degree B-axis swiveling tool post, rather than relying only on X/Z interpolation, giving better roundness and surface finish.
Q: What is the maximum sphere diameter the ML-430 can machine?
A: The ML-430 machines spherical workpieces up to Ø60 mm in diameter.
Q: Can the ML-430 do milling and drilling as well as turning?
A: Yes. In addition to the sphere-turning B-axis, it supports gang-type tooling or an optional live turret such as the LS-120SP for drilling, tapping, and milling.
Q: Is the ML-430 suitable for unattended or mass production?
A: Yes. With automatic door, parts catcher, spindle air blow, a 150 L coolant system, and optional rear chip conveyor, it is built for long, stable production runs.
Q: Who manufactures the ML-430?
A: The ML-430 is designed and built by Ingenious Machinery (formerly YDPM), a CNC machine tool manufacturer based in Taichung, Taiwan, with over two decades of experience.
The ML-430 is more than a lathe — it is a dedicated solution to the complex challenge of ball turning and sphere turning. With precise B-axis control and a rigid structure, Ingenious Machinery (formerly YDPM) helps automotive and medical manufacturers reach new levels of precision and productivity.
