The milling head of the first library is a machine tool accessories for large gantry (door width 2-3m), the installation allows tool center of rotation of the machine spindle center at an angle, you can increase the range and adaptability of the machining can be reduce repeat workpiece clamping, improve processing efficiency.Angle head is a kind of machine tool accessories, after installation can make tools to the spindle rotation center into certain Angle, can center of the processing range increased to reduce and adaptability, repeat clamping, improve the workpiece machining accuracy and efficiency. Widely applied in aviation, automotive, mould etc machinery processing in various fields. Angle is mainly used for machining center and In the design process by calculating the check bevel gears, shafts, key parts of the size of the force is determined to make CAD assembly drawings and part drawings and t
