2ST36Y2 CNC Turn-Mill Center | Machine Specifications and Tooling | YS
The 2ST36Y2 CNC Turn-Mill Center builds upon the core advantages of the 2ST36 series—high precision, high efficiency, and a compact machine footprint—and further extends the Y-axis functionality from the main spindle side to the sub-spindle side, creating a more powerful dual Y-axis machining capability.
The machine features a dual-spindle configuration, front-rear twin turrets, and a BMT live tool turret system, enabling eccentric milling, drilling, tapping, slotting, and complex contour machining on both sides of the workpiece. This greatly enhances machining flexibility and process versatility.
With automatic workpiece transfer between the main and sub-spindles, combined with synchronized dual-turret cutting, the machine can complete full front-and-back machining in a single setup. This significantly reduces re-clamping errors and shortens cycle time.
The design fully embodies the concept of “Small Footprint, Large Machining Capability.” It is particularly suitable for high-precision and complex components in industries such as automotive parts, medical devices, aerospace components, and electronics manufacturing. Machine specifications, spindle capacity, tool-station layout and controller options are confirmed with the YS engineering team before the order is built.

17-Tool Live Turret Configuration Enables One-Setup Complex Machining
The machine features a rich and flexible tooling configuration with a modular design, enabling fast and convenient tool changes without the waiting time associated with traditional turret indexing systems. This significantly improves machining efficiency.
Compared with the 2ST36 model equipped with 13 live tools, the 2ST36Y2 further increases tool capacity by adding 4 additional live tools, resulting in a total configuration of 17 live tools, 6 OD turning tools, and 5 ID turning tools, greatly enhancing multi-process machining capability and operational flexibility.
Combined with synchronized operation of the main and sub spindles, the system enables simultaneous machining on both sides of the workpiece. This allows turning, milling, drilling, tapping, polygon machining, and complex contouring to be completed in a single setup, effectively eliminating errors caused by multiple clamping operations.
When integrated with a bar feeder, the machine supports long-duration automated production. It is especially suitable for high-volume manufacturing of hexagonal, polygonal, and small precision components. This significantly reduces machining time while improving productivity and yield rate, making it an ideal solution for high-efficiency and stable mass production.
Product Features
● Dual-Spindle Synchronous Machining for Front and Rear Processing
The machine is equipped with dual front and rear spindles, with both the main spindle and sub-spindle designed to the same Ø36 mm machining capacity, ensuring that the workpiece size range is not reduced during back-side machining.Unlike some machines on the market where the sub-spindle has a smaller specification that limits machining capability, the 2ST36Y2 delivers consistent machining performance on both spindles. After the main spindle completes the front-side operations, the workpiece is automatically transferred to the sub-spindle for back-side machining.
Combined with a front-rear twin turret design, the system supports independent and simultaneous cutting on both sides.This significantly reduces loading / unloading and idle time, enabling a true “one-piece complete machining” process. As a result, production efficiency and machining quality are greatly improved by minimizing setup errors and streamlining the entire workflow.
● Compact Machine Design with High Rigidity for Maximum Space Efficiency
To address the challenge of limited factory floor space in modern manufacturing environments, this machine features a highly integrated structural design. The reduced machine footprint allows for more efficient production line layout and space utilization.
Despite its compact size, the high-rigidity cast iron base effectively absorbs cutting vibrations, ensuring consistent repeat positioning accuracy during long-term continuous machining.
● Full-Enclosed Telescopic Spindle Cover for Clean and Stable Machining Environment
The full-enclosed telescopic spindle cover effectively prevents machining chips from entering the machine interior, reducing chip accumulation and minimizing wear on critical components. It also helps lower maintenance requirements and service workload.Even during long-term continuous machining, the machine maintains a clean operating condition, ensuring stable machining performance and consistent accuracy. This ultimately enhances productivity and delivers higher overall production efficiency for manufacturers.
● Direct-Drive Spindle Design for High-Precision Machining Performance
Adopting full axial direct-drive technology eliminates vibration and power loss caused by traditional belt-driven systems, improving spindle high-speed operational stability, machining accuracy, and workpiece surface quality. This delivers superior performance for high-precision machining applications.

2ST36Y2 CNC Turn-Mill Center | YS Turn-Mill Machining Capability
2ST36Y2 CNC Turn-Mill Center is designed and assembled by YS Precision Machinery for turning, milling, drilling and tapping on one machine, so a component moves from bar stock to finished part without transferring between separate turning and milling operations.
Before an order is confirmed, YS engineers check the relevant bar diameter, axis travel, spindle power, number of driven tool stations and collet type against the part drawing. Tooling layout is modular, which keeps changeover short and lets the tool package be revised for a different family of components later.
Machines are built on a cast iron structure for vibration damping, inspected in-house against YS quality procedures, and covered after delivery by installation, operator training and machining setup support.
