AKB-11 / AKB-13
CNC Horizontal Boring & Milling Machines
FEATURES
- The column traverse allows for heavy-duty workpieces and improves accessibility to the workpiece.
- Standard coil type chip conveyor provides parallel to the X-axis capable of effective swarf disposal and cutting fluid disposal.
- AKB series employs Japanese technology with Japanese quality and reliability, but produced at lower cost than made-in-Japan products.
- High-accuracy indexing ensures standard rotary milling.
- Powerful heavy-duty cutting is capable by a high-torque 2-steps geared head.
- Standard Big-Plus dual contact system.
