Universal milling head definition

The universal milling head, also known as the universal angle head, is a machine tool accessor.

Universal Milling Head

After the machine is mounted on the milling head, the tool rotation center line can machine the workpiece at an angle to the spindle rotation center line.

Originally produced in Europe, it is now widely used in various fields of machining such as aviation, automobiles and molds.

With the milling head, the machining range and adaptability can be increased without changing the machine structure.

It can realize some processing that is difficult to complete by the traditional method, and can reduce the repeated clamping of the workpiece, and improve the processing precision and efficiency.

Mainly used in machining centers and portal milling machines.

The light weight model can be installed in the magazine tool and can be freely converted between the magazine and the machine spindle.

Medium and heavy duty model has greater rigidity and torque for most machining needs.

Since the milling head expands the performance of the machine, it is equivalent to adding a shaft to the machine.

It is more practical than the fourth axis even when some large workpieces are difficult to flip or require high precision.

Please check the different a working planes, the angles of α and β that need to be adjusted.

Type of universal milling head

  1. Light universal milling head

This type of milling head features light weight (generally about 10kg), high precision, low torque, and automatic tool change in the tool magazine.

Such milling heads are positioned by positioning blocks. The output is generally a collet or a BT30 taper shank. Sometimes there are special types which can output CAT or HSK shanks, and some special types directly connect wire taps or face milling cutters.

  1. Heavy duty universal milling head

This type of milling head features heavy mass (generally around 100kg), high precision, and high torque.

Generally only applied to the gantry machine.

These milling heads are fixed and locked with a splicing plate to support any type of output for machining.

  1. Strong universal milling head

This type of milling head features heavy mass (generally around 100kg), high precision, high speed, and high torque. The relative price is also expensive.

Generally only applied to the gantry machine.

These milling heads are fixed and locked with a splicing plate to support any type of output for machining.

Universal milling head application

  • When large workpieces are difficult to fix, when used in simple processing;
  • Precision workpiece, one-time fixed, when processing multiple faces;
  • When processing at any angle with respect to the reference plane;
  • Processing to maintain a special angle of the contour milling, such as ball end milling;
  • Holes in the hole, milling heads or other tools cannot be machined into the hole to machine small holes;
  • Oblique holes, chutes, etc. that cannot be machined by the machining center, such as the engine and the inner hole of the case.

Universal milling head precautions

  1. The general milling heads are all non-contact oil seals.

If cooling water is used during processing, it is necessary to operate before spraying water, and adjust the direction of the cooling water nozzle to spray water on the tool to avoid the penetration of cooling water into the body to prolong the life.

  1. Avoid continuous processing at the highest speed for a long time.
  2. Refer to the parameter characteristics of each type of milling head and use it under appropriate processing conditions.
  3. Before use, you must first confirm the test run for a few minutes.

For each machining, select the appropriate speed and feed machining.

The speed, feed and depth of cut during machining should be adjusted in a progressive manner until maximum processing efficiency is achieved.

  1. When processing with the general standard milling head, it is necessary to avoid the processing of materials that will produce dust and particles (such as: graphite, carbon, magnesium and other composite materials, etc.)
