lic Precision Metal Processing - moving gantry boring & milling machining center

Boring Head main drive square ram horizontal structure, boring milling machine is the core component of its design has the following characteristics:

• spindle 38CrMoTi nitriding treatment, so it has enough to maintain the accuracy of the hardness and good.
• To avoid the temperature rise caused by the spindle rotation speed affect the accuracy of the spindle is cooled to reduce heat injection to prevent heat deformation of the spindle.
• DC motor and the secondary spindle speed to achieve a combination of continuously variable transmission.
• square ram to take the vertical structure of a large cross-section to increase the longitudinal stiffness of square ram to improve the overall stiffness of square ram is beneficial for heavy cutting machine.
Transmission
Transmission of DC motor drive, the mechanical speed and DC speed, get 3 ~ 660r/min (Optional 1000 rpm) speed range-free section in order to meet a variety of machining needs.
Feed drive in four parts: before the column cross feed (X coordinate), headstock vertical feed (Y coordinates), the axial feed boring axis (Z coordinate) and axial feed ram (W coordinate.)
Click the feed AC servo motor are used, and thus feed for the stepless speed drive, the maximum feed rate is the fast-moving speed.
