Universal milling head definition
The Universal Milling Head, also referred to as the Universal Angle Head, is a machine tool accessory.
After mounting the machine on the milling head, the tool center line can machine the workpiece at an angle relative to the spindle center line.
Originally developed in Europe, this technology is now widely used across various industries such as aviation, automobiles, and mold making.
The addition of a milling head increases the machining range and versatility of the machine without the need for structural changes.
It enables the completion of complex processing tasks that are difficult to accomplish with traditional methods, reducing the need for repeated workpiece clamping and improving processing precision and efficiency.
It is primarily used in machining centers and portal milling machines.
The lightweight model can be installed in a magazine tool and easily switched between the magazine and the machine spindle.
The medium and heavy-duty models offer increased rigidity and torque, making them suitable for most machining needs.
By expanding the performance of the machine, the milling head is like adding another axis to the machine.
It is a more practical solution than the fourth axis, especially for large workpieces that are difficult to flip or require high precision.
Please ensure that the correct working planes and angles of α and β are adjusted.
Type of universal milling head
- Light universal milling head
This type of milling head is characterized by its lightweight design (typically around 10kg), high precision, low torque, and the ability to automatically change tools using the tool magazine.
These milling heads are positioned using positioning blocks, and the output is typically a collet or a BT30 taper shank. There are also special versions that can output CAT or HSK shanks, and some even directly connect wire taps or face milling cutters.
- Heavy duty universal milling head
This type of milling head is characterized by its heavy weight (typically around 100kg), high precision, and high torque.
It is primarily used on gantry machines.
These milling heads are securely fixed in place with a splicing plate to accommodate any output required for machining.
- Strong universal milling head
This type of milling head is characterized by its heavy weight (typically around 100kg), high precision, high speed, and high torque. Additionally, it is also relatively expensive.
It is primarily used on gantry machines.
These milling heads are securely fixed and locked in place with a splicing plate to accommodate any output required for machining.
Universal milling head application
When large workpieces are challenging to secure during simple processing.
Precision workpieces require a one-time fix during multi-face processing.
Processing at any angle with reference to the reference plane is possible.
Special angles of contour milling, such as ball end milling, can be maintained during processing.
Small holes cannot be machined using milling heads or other tools when they are in the hole.
Machining centers are unable to machine oblique holes, chutes, and other similar structures, such as engine inner holes and case holes.
Universal milling head precautions
The general milling heads have non-contact oil seals.
If cooling water is used during processing, it’s important to start the operation before spraying water and adjust the cooling water nozzle direction to spray the tool, to prevent the cooling water from penetrating into the body and extending the life.
Avoid operating at the highest speed for a prolonged period of time.
Consult the parameter specifications for each type of milling head and use it under appropriate processing conditions.
Before usage, ensure to run a test for a few minutes.
For each machining operation, select the appropriate speed and feed rate.
Gradually adjust the speed, feed rate, and depth of cut during machining until maximum efficiency is achieved.
When using the general standard milling head, avoid processing materials that produce dust and particles, such as graphite, carbon, magnesium, and other composite materials.
