Features

• High Rigidity Structure

  The VTL series is designed for high-composite, high-efficiency, and heavy-duty processing needs. It features a symmetrical door frame structure with widened dual-column design to enhance support, increasing overall rigidity by 50%. This design effectively resists cutting forces, providing more stable machining performance.

  The column slide rails are designed with a large span to fully envelop the workpiece, ensuring that the machining stroke remains within the optimized range, enhancing machining stability and extending machine life while ensuring precision.

  The crossbeam’s hard rail end faces have been shortened to reduce torque during turning, thereby increasing machining stability.

• Single-Column Integrated Structure (VTL1000-2500 Medium-Sized Vertical Lathe)

• All castings are made from premium Meehanite cast iron, properly annealed to eliminate internal stresses, resulting in durable and highly rigid material.

• The bed and column use a box-type structure and thick-walled rib design, minimizing thermal deformation and providing strong support during heavy cutting.

• Door-Type Column Structure (VTL3000-4500 Large Vertical Lathe)

  The base bed features a circular radial rib design to effectively address stress concentration issues and ensure even load distribution. This provides greater shock resistance and reduced deformation, resulting in excellent stability and precision.

  The column is widened and thickened to significantly enhance rigidity and stability of the vertical lift column.

  Increased span of the dual-column rails not only provides a larger effective machining range but also ensures machining precision and stability.

• Machine Structure

  The bed and column feature a box-type structure with thick-walled ribs to minimize thermal deformation. Castings undergo appropriate heat treatment to ensure high overall rigidity and resistance to heavy cutting.

• High-Rigidity Sliding Table Structure

  The symmetrical box-type design has advantages against thermal deformation. Combined with the symmetrical crossbeam and pre-tensioned large-diameter lead screw, it ensures precision. The sliding surfaces are professionally ground to achieve the highest precision.

• Hard Rail Structure:

  X-axis and Z-axis employ high-rigidity hard rail design. The sliding surfaces are professionally ground and covered with low-friction wear-resistant material, Turcite-B, to ensure high precision and responsiveness of the sliding table.

  The sliding rails feature a central automatic lubrication system that provides regular, controlled oiling to improve machine accuracy and longevity.

• Crossbeam Lifting Structure

  The crossbeam can be lifted in fixed stages (200mm per stage) and adjusted automatically up and down according to the height of different workpieces via M-Code. After positioning, four hydraulic cylinders automatically clamp and fix it to ensure optimal machine rigidity and precision.

• Cross-Roller Bearing

  The large span of the contact points and proximity to the workpiece allows for the support of loads from all directions, providing robust spindle support for long-term heavy cutting.

  The mechanism's uniform heat dissipation and low friction characteristics help maintain high precision and stability while extending machine life. 

  The low friction coefficient and low inertia result in operation with minimal torque, significantly reducing energy consumption.

  The dual-cone cross-roller design results in low heat generation and precise control of workpiece diameter and geometric accuracy.

• CF Axis High-Precision Indexing Mechanism

  The VTL1000-2500ATC+C series features a high-precision servo motor-driven CF axis mechanism, providing accurate indexing precision. This mechanism, combined with the vertical lathe, offers both turning and milling functions, reducing machine investment costs.

• CS Axis Dual-Spindle Indexing Mechanism

  The VTL3000-4500ATC+C series (and optionally VTL2000-2500ATC+C series) features a unique dual-spindle motor-driven CS axis indexing mechanism, enhancing output torque and eliminating backlash in the drive mechanism. This results in high precision and torque output, ensuring stable and precise indexing motion for superior surface finish quality. Indexing precision is: repeatability ±5 seconds, positioning accuracy ±10 seconds.

• Z-Axis High-Rigidity and Stability Design

  The sliding saddle uses a closed structure combined with the main spindle for higher structural rigidity and machining accuracy.

  The Z-axis slide column is driven directly by a high-efficiency AC servo motor with a balancing cylinder, providing high responsiveness and meeting high-precision machining requirements.

Our CNC Vertical Lathes are renowned for their high-rigidity structure, which is crucial for high-composite and heavy-duty processing. The symmetrical door frame structure, combined with a widened dual-column design, increases overall rigidity by 50%. This design not only resists cutting forces more effectively but also enhances the machine's stability and performance. The column slide rails are optimized to fully envelop the workpiece, maintaining an ideal machining stroke and extending the machine's lifespan while ensuring top-notch precision.

The VTL series is available in multiple models, including the medium-sized VTL1000-2500 and the large VTL3000-4500. The medium-sized lathes feature a single-column integrated structure with premium Meehanite cast iron castings, annealed to eliminate internal stresses. This material ensures durability and rigidity, while the box-type structure and thick-walled rib design minimize thermal deformation.

In contrast, our large vertical lathes utilize a door-type column structure with a circular radial rib design for the base bed, effectively addressing stress concentration and ensuring even load distribution. This design enhances shock resistance and stability, crucial for high-precision applications. The widened and thickened column further improves rigidity and stability, ensuring accurate and consistent machining.

Our machines are equipped with a high-rigidity sliding table structure and hard rail design, with the X-axis and Z-axis featuring professionally ground sliding surfaces coated with low-friction wear-resistant material. This setup, coupled with a central automatic lubrication system, ensures high precision, responsiveness, and extended machine life.

The cross-roller bearing mechanism is a standout feature, providing robust spindle support with minimal friction and uniform heat dissipation. This design not only maintains high precision and stability but also reduces energy consumption, thanks to its low friction coefficient and low inertia.

Additionally, the VTL series includes high-precision indexing mechanisms, such as the CF axis and CS axis dual-spindle mechanisms, which enhance indexing precision and torque output. This results in superior surface finish quality and high accuracy.

In summary, our CNC Vertical Lathe Machines with cross-roller bearings represent the pinnacle of precision engineering and durability. They are engineered to deliver exceptional performance in demanding machining environments, making them the ideal choice for professionals seeking reliable and high-quality machining solutions.
