BHE machines are manufactured entirely in cast iron parts: base, columns, traverse and RAM (Z axis) of size 380x380mm, are designed with FEM system.
X axis with 4 linear guides (models with Y > 1700mm)
4 linear guides are mounted in the machine bed to grant excellent dynamics and max payload on the table:
- 2 Roller guidesa
- 2 Linear guides
Y axis with the exclusive solution of 3 roller guides
The movement of the Y drive is accomplished through 3 linear roller guides to ensure maximum rigidity and accuracy even in movements at high speed:
- 2 Roller guides mounted on the top of the traverse
- 1 Roller guide mounted on the front of the traverse
RAM designed with Box-type technology and made of special casting with dimensions 380x380mm, for Z axis travel 700 and 900mm. The axis movement is supported by 4 Box ways treated with anti-friction “ROLON” material and 8 points of contact.
To increase stiffness in models with Z 1100mm and 1300 mm Z travel, RAM has dimension 420x420mm. For higher dynamics 4 linear roller guides can be installed optionally.
Digital drives & Linear scales
For maximum precision and to avoid problems due to thermal expansion, on all axes are mounted digital pressurized scales. The Fidia digital drives technology and the use of high resolution optical scales allow to optimize the machine tool dynamics and to achieve the maximum machining resolution and accuracy, even in high speed.
Spindle designed to meet all the machining requirements
As standard a compact and robust system with direct coupling and 1:4 ZF box to avoid gaps, noise and thermal deformation is provided:
6000 rpm BT # 50/ISO50 with motor 17/25kW 162/239 Nm and ZF 1:4 gear with 956 Nm of maximum torque.
“Long nose” design to allows greater penetration into the cavities.
The whole line of spindles are oil cooled.
