Description

EUMASEIKI CNC vertical machining centres are high-performance machines intended for complex workpiece machining,covering the range of technologies from the high-torque to the high-speed machining.The machine is formed by two steady castings,the base and the column.The column is provided with guideways along the spindle head travel. The work table travels in the longitudinal direction (X-axis) along the cross saddle. The cross saddle moves in the transverse direction (Y-axis) along the base. All guideways are formed by linear guideway with rollers. Their size and locations allow a high load of the table, saddle and spindle head while the high accuracy processing are kept even at the interrupted cut. These technical also ensures the machine long service life to enable the stability milling, drilling, boring, reaming and threading operations on work pieces made of steel, cast iron and light-metal as well as nonferrous metal alloys.
