The NHT Series features a T-shaped bed structure with a front-mounted gearbox layout, utilizing high-rigidity roller linear guides on the horizontal axis and rectangular guideways on the vertical axis. It is primarily composed of components such as the bed, column, spindle, worktable, hydraulic system, lubrication system, cooling system, pneumatic system, chip conveyor, operator panel, and electrical control system.
The column adopts a centrosymmetric design with a center box structure. The frame-type column features superior rigidity and minimal deformation under force. Unlike the side-mounted offset spindle that causes torsional deformation of the column, the center box ensures high machining accuracy..
The Hydrostatic rotary table is driven by a dual pinion anti-backlash mechanism to guarantee transmission accuracy and rigidity, and is equipped with a standard circular grating for closed-loop detection. It adopts a hydrostatic circular guideway support structure, and the guideway surfaces are finished by manual scraping to ensure the reliability and stability of the contact surfaces.
The W-axis telescopic precision spindle consists of a boring spindle, a milling spindle, a tool clamping device and other components, guided by high-precision linear guideways. The combined design of bearing oil-air lubrication system & coolant oil cooling system minimizes the thermal deformation of spindle to the greatest extent.
The Y-axis guideway structure is quenched and ground with a large cross-section, delivering excellent rigidity. Seven contact surfaces ensure the symmetry of thermal deformation in all directions
The HISION Arm Type Tool Magazine (Opt.) is equipped with a manipulator introduced with Japanese technology, featuring stable and reliable performance.
This machine is particularly suitable for hole machining and surface processing of box-type components and is widely used in industries including automotive manufacturing, rail transportation, petroleum valve production, plastic machinery, mining equipment, and general machinery.
