Vertical CNC Turning Lathes: Machining Range
Vertical CNC turning lathes are primarily used for machining large-diameter, relatively short, and heavy rotational parts such as discs, covers, and wheel hubs. Their core advantage lies in utilizing a vertical spindle and worktable, which facilitates the clamping and alignment of heavy workpieces.
The machining capacity varies significantly across different specifications. Here is a comparison:
| Specification Type | Typical Model/Series | Max. Machining Diameter (mm) | Max. Workpiece Height (mm) | Max. Workpiece Weight (t) | Characteristics & Application Fields |
|---|---|---|---|---|---|
| Small/Medium | CK514 | Φ650 | 350 (Turning Height) | – | Compact structure, suitable for small/medium discs and covers. |
| C5112/C5116 | 1250 – 1600 | 1000 – 1800 | ~ 3.25 | High versatility, suitable for single-piece and batch production. | |
| Large/Heavy-Duty | CK5263 | 6300 | 3000 – 4000 | 63 – 100 | Double-column structure, high rigidity, used for large components in wind power, heavy machinery, etc. |
| Specialized Type | ECK6520BL | Φ80 – Φ160 (Piston) | – | – | Designed specifically for piston non-circular OD and ring grooves, capable of non-circular turning. |
Core Machining Capabilities & Scope
Beyond size, their machining scope also includes:
Broad Process Capabilities: In addition to standard OD/ID cylindrical surfaces, conical surfaces, facing, and grooving, they can machine threads and various complex rotational contours. By adding functional components (e.g., milling heads, grinding heads), they can also achieve composite machining like milling, drilling, boring, and even grinding.
Wide Material Adaptability: Using tools made of HSS or carbide, they can process ferrous metals (e.g., steel), non-ferrous metals (e.g., aluminum, copper alloys), and some non-metallic materials. For example, specialized models can efficiently machine aluminum or steel pistons.
High Precision & Automation: Modern vertical CNC lathes can achieve machining accuracy up to IT6-IT7 grades. By equipping automatic tool changers, tool setters, automatic loading/unloading manipulators, or integrating with robots, they enable highly automated production.
How to Select the Right Equipment
When choosing, you can focus on the following key points:
Workpiece Dimensions & Weight: This is the primary factor. Ensure the part’s diameter, height, and weight are within the machine’s allowable range.
Process Complexity: If composite operations like milling or grinding are needed, confirm in advance whether the machine supports them or if corresponding functional components can be optionally equipped.
Production Batch & Automation Needs: High-volume production should consider systems for automatic loading/unloading; small-batch, high-variety production prioritizes machine versatility and ease of adjustment.
Machining Accuracy & Surface Finish: Check the machine’s positioning accuracy, repeatability, and guaranteed surface roughness (e.g., Ra value).
