ETL1250 / ETL1600 / ETL2000 / ETL2500

◈ It is easy to load and unload large, thin, heavy and irregularly shaped products.

◈ Due to the weight of the workpiece, the workpiece and the fixture can be ensured to be tightly fitted, and the loading and unloading time of the workpiece is short and stable.

◈ There is no problem of poor roundness caused by the self-weight inertia when holding the workpiece as in a horizontal lathe.

◈ Multi-functional settings, optimal operation, and the lowest investment cost.

◈Thermal-symmetrical column structure with effective vibration isolation. High rigidity and anti-vibration capability.

◈Max torque spindle motor for heavy cutting, standard German ZF reducer.

◈2-speed automatic gearbox for both large diameter low-speed heavy cutting and small diameter high-speed cutting.
