Product details

Structure Design

BThe series is a high-speed Longmen type CNC milling machine designed and developed for the new generation of exclusive mold manufacturing and precision parts processing, with a high rigidity machine structure

Designed to support high-speed milling, it can be paired with a high-speed straight spindle to increase the machine's heavy cutting capacity and shorten the processing time of molds and parts.

Ÿ The entire machine adopts high-density transmission components, which indeed meets the manufacturing requirements of high speed, high temperature, and high efficiency.

Ÿ Extra large column design: The uniquely designed column structure is more stable than other models in the same class, and is vertically combined with the base, making it more capable than traditional models

Ÿ Maintain the overall geometry of the machine.

Ÿ Saddle structure design:

Ø Adopting a stepped space design, the left and right sliders elevate the span, greatly enhancing axial dynamic rigidity and increasing cutting rigidity.

Ø Completely uniform symmetrical design and perfect thermal balance structure design reduce thermal deformation caused by high-speed operation, making the fuselage structure more stable.

workbenches

The workbench has undergone rigorous grinding and serves as a benchmark for machine accuracy, ensuring reliable and stable accuracy. Improve the load capacity and have a wide processing range

Load capacity. The workbench has8Sliding block support ensures that the load is evenly distributed on the base, ensuring high rigidity of the workbench at maximum load.

Strong and rigid base

Machine base procurementTType architecture, super rigidity, combined with reinforced design of each axis, maximizes rigidity and stability, providing a reliable foundation,

Ensure accuracy during high-speed processing.

Internal spindle temperature rise compensation system: [Limited]IBAGConcealed spindle

The built-in spindle in the entire series of machines can be equipped with a spindle temperature compensation system to ensure machining accuracy.

Spindle cooling system-Oil cooler: Ensure constant temperature during continuous operation, effectively suppress spindle temperature rise, and achieve optimal heat dissipation effect.
