Condition: used, Year of construction: 2023, In the market for a Top of the Range Miyano? Then have a look at this one! 18 months old and just over 1000 hours on the clock…it is as new! Still on site where it can be seen under power. The following is from Miyano’s Spec sheet: The Miyano ABX-64SYY – is a Top of the range, twin spindle, twin turrets with Y-axis on each turret. The ability to machine simultaneously at the left and right spindles using the upper and lower turrets, both featuring a Y-axis function, means that complete front and back machining of products with complex shapes can be accomplished simply and in a short time. High rigidity and high torque with 40 Nm driven tools. The use of rigid 40 Nm driven tool drives capable of heavy cutting ensures stable milling. Two turrets with a total of 24 tool positions, all driven, handle complex machining just like a machining centre. This machine also features the optional parts conveyor, Hainbuch collet chucks on both spindles, high pressure coolant, probing and a steady rest that’s mounted on the lower turret.
