CNC very-small-hole drilling machine
K1BL
|
High response of linear motors secures continuous and high-precision drilling of very small holes.
The machining range of "K1BL", equipped with a proprietary linear motor provided on the main axis (Z axis), covers the range not covered by models with conventional drive system. In addition, the high response of the linear motor increases the machining speed and reduces the electrode wear significantly. |
|
- Linear motor provided on main axis
A high-speed, high-response linear motor provided on Z axis expands the machining range, stabilizes the operation and reduces the electrode wear.
- High-rigidity double-column structure
A high-rigidity double-column structure has been adopted to enable drilling of very small holes. The structure, wherein a column is held by two struts, secures good resistance to thermal deformation and high rigidity, remarkably enhancing machining accuracy.
- Electrodes for drilling very small holes
Electrodes Φ0.08 to 0.25 mm with a shank are excellent in rigidity and minimize chatter; suited for drilling very small holes.
- CNC power unit, "LN10K"
K1BL is equipped with a CNC power unit, "LN10K", which extracts the performance of the linear motor to a maximum extent, realizing improved machining performance and easy operation.
- Automatic electrode changer (AEC)
An AEC provided for this model changes electrodes reliably to facilitate long and continuou drilling of many holes.
