Rugged construction throughout guarantees superior rigidity and stability.
BT-50, 8000RPM direct drive spindle combined with high/low speed gearbox meets the requirements of high speed, high precision and high torque output at low speed. Also, available to equip with coolant through spindle for efficient cooling on work piece and tool in heavy cutting. This also results in longer tool life and higher parts accuracy.
The base and the column are box type, one-piece construction combined with solid support for maximum stability when loading extra large work piece.
Wide range application for BT50 8000RPM spindle, can machining with 1700mm, max length 4000mm, height 900mm work piece.
The spindle head is a symmetrical layout with box type construction. Shortened distance between spindle center and Z-axis slideway faces. The spindle head operates together with a gearbox to fully exhibit extra heavy cutting xapacity.
