Multifunctional bar center
Equipped with a bar head featuring the largest W-axis spindle diameter in its class at φ130mm and a stroke of 555mm, it powerfully supports boring operations. Furthermore, it comes standard with a spindle core cooling system that significantly suppresses thermal displacement, reducing it to 1/4 of conventional systems. Combined with the synergistic effect of the square slide column traverse type machine structure, it exhibits excellent machining capabilities even when boring difficult-to-machine materials.
Benefits of introducing the HN-BAR series
-
- HN-E BAR Series
-
- Cantilevered horizontal boring machine
High precision
The double column and center spindle have a thermally symmetrical structure, and a double guide system is employed for the Y-axis to reduce thermal deformation.
High rigidity
Machining is possible with exceptional spindle accessibility. The synergistic effect of the large diameter φ130mm spindle and machine rigidity provides superior rigidity, exceeding that of long tools.
Productivity
2APC and high-speed ATC reduce cycle times and deliver exceptional productivity.
Safety and workability
The full cover ensures the operator can work safely and securely. Coolant and chips will not scatter, reducing the burden of cleaning.
Corner slide × Column traverse structure
It employs a column traverse structure in which the column moves back and forth.
By aligning the column guide surface center, ball screw center, and spindle center on the same line, stable machining accuracy is achieved.
Furthermore, its high rigidity and high damping structure, thanks to its angular slide design, provides excellent machining capabilities even when boring operations are performed using a bar head.
Processing examples
End plate for injection molding machine
Because the end plates of injection molding machines are large and require high precision, high mechanical rigidity is essential. Furthermore, the burden of setup changes becomes greater with large workpieces.
The BAR series' high-rigidity machine structure and BAR spindle enable deep hole drilling in a single chucking without setup changes, achieving both high-precision machining and productivity.
