BM Series
Bridge Mill and Double Column
STRONG & STABLE
Incredible spindle power and machine rigidity.
The long nose design on the 12,000 RPM dual contact BIG-PLUS taper spindle lets you mill the deep pockets commonly found in mold applications, and multiple rails of linear roller guideways add to the BM’s rigidity.

STAY TRUE
Linear scales are standard on all XYZ axes.
The BM Series supplies accuracy you can take to the bank. Thanks to its ball screw nut cooling and thermal displacement compensation—both standard features—you can be sure the machine is where it says it is.
STAY SMOOTH
Vital software is packed into the BM “M” Series.
In die mold applications, smooth surface finishes are a must. With that in mind, Doosan’s die mold package software comes standard on every BM “M” Series. The competition makes you pay for bonus features like these. At Doosan, they’re standard.
