Complex Machine BTM Series


Machining Part

BTM Series provide boring, turning, milling, drilling and slotting in vertical, horizontal and diagonal machining for casing and housing applications

Machining Part Machining Part


BTM08YS-2 is a multi-operation machining center designed to function as vertical lathe, horizontal and certical machining cener.

  • Multiple Operations

    BTM Series offer various operations such as boring, turning, milling and drilling, etc.

  • Multi-sided Machining

    Vertical, horizontal and diagonal plane machining in one single set-up and chucking.

  • Integrated Machining Process

    Lower space and fewer machine requirement in production line due to integrated machining process of vertical lathe and vertical/horizontal machining center.

  • Man-hour Saving

    Minimize set-up change intervals and times.

Multi-operation with multi-sided machining in one single set-up and chucking

Multi-operation with multi-sided machining Multi-operation with multi-sided machining

Swing head allows to index at any position of every 5 degrees within 90 degrees, vertically or horizontally (every 1 degree as an option) with C axis indexing function that performs multi-sided machining in one single set-up and chucking
