    High Rigidity Horizontal Boring Mills

    Introducing YAMA SEIKI with mature manufacturing abilities and advanced technology skills. The BL series combine high rigidity structure, heavy duty load capacity rotary table and a high torque spindle ( BL-S ) or high speed spindle ( BL-FM ) along with our professional assembly and hand scraping skills. BL series can easily overcome most stringent requirements of not only deep hole boring but high precision mold milling which meet your various needs for today and the future.BL Series X Y Z travel

    With years of innovation and manufacturing experience on horizontal boring mills, combined with the latest machining center technology, to maximize the mechanical performance and the brand image as a professional boring mills manufacturer.

    Modular spindle design, BL-S quill type 2-steps gear box spindle continuous torque can be 1,308 Nm ( 960 ft-lb ) ; BL-FM ram type built-in spindle speed up to 8,000 rpm

    High Rigidity Structure


    BL-S series Quill Type Spindle – Parts Processing

    Quill diameter Ø 120 mm ( Ø 4.72″ ), W-axis travel can extend to 600 mm ( 23.62″ ).
    Max. spindle speed at 2,400 rpm with 2-step gear box which can provide maximum torque output at 1,308 Nm ( 960 ft-lb ) under 189 rpm.
    W-axis feed system combined ball screw with linear guide ways, W-axis extension can be determined according to different kinds of processing requirement.
    All series is equipped with a spindle oil cooler and cooling jacket, the temperature-regulated volume of cooling oil automatically maintain the temperature of bearings, motor, and gears within precisely defined range which effectively reduce the spindle thermal deformation thus achieving higher machining accuracy.


    BL-FM series Ram Type Spindle – Mold Processing

    Strong ram with cross section at 480 x 470 mm ( 18.89″ x 18.49″ ), W-axis travel can extend to 600 mm ( 23.62″ ).
    Max. spindle speed at 6,000 rpm ( 8,000 rpm as option ) with built-in spindle which can provide maximum torque output at 600 Nm ( 440 ft-lb ) under 350 rpm.
    W-axis feed system combined ball screw with linear guide ways, W-axis extension can be determined according to different kinds of processing requirement.


    High Performance Rotary Table High damping, low friction oil floating design rotary table along with high rigidity fully support base provide maximum table load capacity at 12,000 kg ( 15,000 kg lb as option ) [ 33,000 lb ( 26,500 as option ) ].
