200MSY/200MSY With Sub-Spindle Y-Axis CNC Slant Bed Lathe

200MSY CNC Slant Bed Lathe Introduction

The function of 200MSY/200MSY With Sub-Spindle CNC Slant Bed Lathe With Y-Axis is realized by a flat bed equipped with a 35º oblique interpolation Y-axis and a power milling turret. Multiple processes such as turning, milling, boring, drilling, tapping, and reaming can be completed in one clamping. It can reduce the number of clampings, improve processing accuracy, shorten the product manufacturing process chain, and improve production efficiency.

1. The high-rigidity Y-axis is realized through the movement of the middle (inclined) and large (horizontal) slides, which involves continuous two-axis interpolation. This enables milling operations with maximum rigidity.
2. The driven tool turret integrates the slide and utilizes a high-precision three-piece contrate-gear clutch. This ensures high positioning accuracy, excellent repeatability, and strong clamping rigidity.
3. The high-rigidity spindle employs both liquid and air cooling methods for motor heat dissipation. This approach guarantees the spindle's service life and machining precision.
4. The programmable tailstock is equipped with overload protection and is driven by a servo motor for movement and clamping. This significantly improves machining efficiency.

Description of the basic structural features of the Lathe machine tool

1. Bed

L-shaped high-rigidity bed structure made of high-grade inoculated cast iron. Through FEM finite element structural analysis, the casting interior incorporates a large number of reinforcing ribs, optimizing the internal load-bearing structure of the entire machine and ensuring its rigidity and thermal field stability.

2. High-rigidity interpolation Y-axis structure

The upper and lower slides form a 35° inclined Y-axis structure, achieving high-rigidity Y-axis characteristics. The Y-axis is realized through the X-axis and a Y1-axis with a certain angle relative to the X-axis. The upper and lower bed saddles form a virtual Y-axis structure by interpolation on the high and low bed frames, with the Y-coordinate perpendicular to the X-coordinate. When the Y-coordinate moves, the X-axis and Y1-axis move simultaneously. This structure effectively overcomes the shortcomings of direct Y-axis structures, enhancing machine tool rigidity, particularly during heavy-duty turning operations (no tool holder overhang on the Y-axis). Another feature of this structure is its rational machine layout, compact footprint,and high cost-effectiveness.

3. Integrated Tray-Type High-Rigidity Power Tool Turret

The power tool turret is integrated with the lathe's tray and directly connected to the guideway. Compared to the traditional structure where the turret is a separate functional component connected to the tray, this design is more compact. Under the same structural dimensions, it can use a larger end gear disk, thereby achieving higher rigidity and better stability.

The power module is housed within the tool turret tray and directly connected to the drive servo motor, eliminating intermediate synchronous belts or other transmission chains, resulting in agile and high-precision transmission.
The power module is housed within the tool turret's tool disk and directly connected to the drive servo motor, eliminating intermediate synchronous belts and other transmission chains, resulting in agile and high-precision transmission. The servo motor drives the gears for tool selection and indexing, hydraulic release and locking, and high-precision three-piece end-tooth clutch positioning. The high-durability non-separable design ensures excellent positioning accuracy, repeatability, and clamping rigidity.

4. High-precision, high-torque permanent magnet synchronous spindle

Based on permanent magnet synchronous motor theory, the high-rigidity, high-torque synchronous spindle has a rated output torque of 220 N·m, maximum output torque 606 N·m, and maximum speed 3,000 RPM.
The permanent magnet synchronous spindle eliminates the traditional belt structure, improving the machine tool's response speed and enhancing processing efficiency;
the machine tool adopts a direct-coupled structure, improving processing accuracy to meet high-speed precision machining requirements;
it addresses the issue of insufficient low-speed high-torque rough turning force in machine tools.

5. High-rigidity roller guideways

Roller guides feature high rigidity, high load-bearing capacity, and high precision, making them particularly suitable for high-load, high-speed applications.
Compared to ball guides, roller guides have more contact points, allowing for even load distribution and reduced relative friction during movement, resulting in high precision and high repeatability.
Roller guides have a long service life and can be used in high-load, harsh environments for extended periods, thereby reducing the frequency and cost of replacement and maintenance. Maintenance of roller guide rails is relatively simple; during use, only proper lubrication according to specifications is required.

6. Programmable Tailstock

Programmable tailstocks offer advantages such as high automation, high precision, strong flexibility, wide applicability, and convenient maintenance, making them suitable for processing rotating workpieces that require high precision and repeatability.
The adjustment and positioning of the programmable tailstock can be controlled through programming, ensuring precision and repeatability. Driven by servo motors and ball screws, the tailstock generates consistent clamping force.
Through system programming, the thrust in the Z-axis direction of the tailstock can be adjusted to meet the corresponding clamping force requirements of materials in different processing environments.
It provides support for long and heavy workpieces to achieve consistent high-precision turning processing.

7. Optional Sub-Spindle

The 200MSY-type interpolation Y-axis turning and milling composite center can be equipped with a permanent magnet synchronous sub-spindle with a rated output torque of
37 N·m, a maximum output torque of 130 N·m, and a maximum speed of 3,500 RPM. It enables operations such as single-setup turning and face turning.
