CNC High Speed Round Table Vertical Turning Machine
VLK-1250 | VLK-1600
**Key Features:**
- Main castings are made of high-quality cast iron, with stress-relieving treatment to ensure minimal deformation over time.
- X/Z-axis are equipped with large box-way guideways, enhancing the stability and rigidity of the machine.
- All structural parts are reinforced with rib-type design, improving overall strength and durability.
- The guideways on all axes and columns are ground after quenching, achieving a hardness of 45–55 HRC for long-lasting performance.
- Slide guideways are fitted with high-performance wear-resistant soft belts, reducing friction and extending service life.
**Vertical Tool Post:**
The tool post features a double balance cylinder and motor located in the middle, ensuring stable lifting of the ram and accurate machining of workpieces. Both X/Z-axes use forced lubrication systems that automatically lubricate when the machine starts, maintaining optimal performance.
**Worktable Drive:**
A two-speed motor with low and high speed is used, driving the worktable rotation through a narrow V-belt, allowing for high-speed operation and efficient cutting.
**Lifting Screw:**
This model uses a dual hoisting structure, where an AC motor drives the screw via a gear box on both sides of the column. This design improves horizontal accuracy and stability compared to traditional CNC vertical lathes.
**Positioning Clamping System:**
The machine has four clamping points on the back of the beam, with interlocking mechanisms between the clamping system and the beam lifting motor. The evenly distributed clamping points ensure even force application, securing the beam tightly to the column during operation.
**Feed Unit:**
Tool-post horizontal feed (X-axis) and ram vertical feed (Z-axis) are driven by AC servo motors through a gear reducer and ball screw. The flexible coupling ensures high transmission efficiency, minimal error, and precise movement.
**Four Station Electric Tool Turret:**
Featuring high positioning accuracy, strong clamping force, and high load capacity, this turret offers reliable and stable performance. Its unique dovetail cutter holder provides more accurate positioning and greater clamping force.
**Electrical Cabinet:**
The electrical cabinet is integrated into the column, making the structure compact and space-saving. It has clear wiring, a neat layout, and a special cable connection to the bed. Equipped with an air conditioner, it maintains a stable temperature for the controller, ensuring consistent performance.
