Universal milling head, also known as universal milling head or universal angle head, is a kind of machine tool accessories, machine tools installed milling head after the tool rotation centerline can be angled with the spindle rotation centerline processing workpiece. Originally from Europe, now widely used in aviation, automotive, mold and other machining areas. The use of milling head, without changing the structure of the machine tool can increase its processing range and adaptability, so that some of the traditional methods difficult to complete the processing can be realized, and can reduce the repeated clamping of the workpiece to improve processing accuracy and efficiency.
The following is to explain the classification and application occasions of universal milling head:
Classification:
1. lightweight universal milling head - this type of milling head is characterized by light weight (generally about 10kg), high precision, small torque, can be into the tool magazine for automatic tool change. This kind of milling head with positioning block positioning, output generally for the barrel clamp or BT30 taper shank, sometimes there are special can output CAT or HSK shank, there are also some special directly connected to the silk tapping or face milling cutter.
2. heavy-duty universal milling head - this type of milling head is characterized by heavy mass (generally in the 100kg or so), general precision, torque and other characteristics, generally can only be applied to the gantry machine tools. This type of milling head is fixed and locked with a connecting disk, which can support any type of output for processing.
3. Powerful universal milling head--This kind of milling head is characterized by heavy quality (generally around 100kg), high precision, high speed, high torque and other characteristics, the relative price is also more expensive, generally can only be used in gantry machine tools. This type of milling head is fixed and locked with a connecting disk, which can support any type of output for machining.
Application occasions:
1.When large workpieces are difficult to fix, when used in simple processing;
2.Precision workpieces, one-time fixation, when multiple surfaces need to be processed;
3.Relative to the reference plane, when processing at an arbitrary angle;
4.processing to keep in a special angle for profiling milling pin, such as ball end milling processing;
5. Hole in hole, milling head or other tools can not probe into the hole when processing small holes;
6. Machining center can not be processed oblique holes, oblique grooves, such as engine, case internal hole.
