What is an angle head? What are the applications and classifications of an angle head? The angle head is a common machine tool accessory. After the angle head is installed on the machine tool, the output centerline of the tool and the centerline of the machine tool spindle can form a specific angle to process the workpiece. It is widely used in energy, aviation, automobile, mold and other mechanical processing. In various fields, machining processes such as milling, drilling, tapping, and boring pins can be completed. Using the angle head, it can greatly increase the processing range and adaptability without changing the structure of the machine tool, realize vertical-horizontal conversion five-sided processing and specific angle inclined surface processing, and make some processing that is difficult to complete by traditional methods, such as narrow space and deep cavity. The processing can be realized, and at the same time, the repeated clamping of the workpiece can be reduced, and the processing accuracy and efficiency can be improved.

What types of machine tools are the angle heads suitable for?

The angle head is mainly used in machining centers, boring and milling machines, vertical lathes and other machine tools. The angle head of the machining center can be placed in the tool magazine, and can automatically change the tool between the tool magazine and the machine tool spindle, just like a machine with complex special functions. Standard tool holder; medium and heavy angle heads need to have greater rigidity and torque, suitable for heavy cutting processing needs, and are generally rigidly connected through mechanisms such as flanges or automatic head change.

Application of angle head

The angle head can complete the processing procedures such as milling, drilling, tapping, and boring pins. After the angle head is installed on the machine tool, the output centerline of the tool and the centerline of the machine tool spindle can form a specific angle to process the workpiece without changing the structure of the machine tool. It greatly increases its processing range and adaptability, realizes vertical-horizontal conversion five-sided processing and specific angle bevel processing, and enables some processing that is difficult to complete with traditional methods, such as narrow space and deep cavity processing, and can reduce the repeated installation of workpieces. Clamp, improve machining accuracy and efficiency. At the same time, the angle head is equivalent to adding an axis to the machine tool, which is more practical than the fourth axis in the case that some large workpieces are not easy to turn over or high precision is required. It is widely used in various fields of mechanical processing such as energy, aviation, automobile, mold and so on.

90° angle head

Angle head classification

1. Single output right-angle head - the output is 90 degrees from the machine tool spindle. This type of angle head is relatively common and has better rigidity, and can be widely used in various applications.

2. Double output right-angle head - the double output is at 90 degrees to the machine tool spindle. The angle head adopts two-way output, and the two-way concentricity and vertical precision are better, which can well solve the problem of manual rotation for users when high precision is required. It eliminates the trouble of angle and meter correction, avoids repeated errors, and improves production and processing efficiency and accuracy.

3. Fixed angle angle head - The angle head is output at a fixed special angle (0-90 degrees), which is used for milling, drilling, tapping and other processing of a specific angle surface.

4. Universal angle head - also known as universal angle head, the angle formed by the rotation center line of the angle head tool and the rotation center line of the machine tool spindle can be adjusted. The adjustable angle range is generally -90~+90 degrees, but there are also some Special adjustable over 90 degrees.

5. Extend the milling head - the output of the extended milling head is 0 degrees with the machine tool spindle (the center is a straight line);

6. Other special angle heads;

Angle head application

1. The inner wall of the pipe or the narrow space and the inner wall of the hole are cut and drilled, etc.;

2. Precision workpieces, fixed at one time, need to process multiple surfaces;

3. When processing at any angle relative to the reference plane;

4. The processing is kept at a special angle for profiling and milling, such as ball end milling;

5. When the hole in the hole, the milling head or other tools cannot penetrate into the hole to process the small hole;

6. Inclined holes, inclined grooves, etc. that cannot be machined by the machining center, such as the internal holes of the engine and the casing;

7. Large workpieces can be clamped at one time and processed on multiple surfaces;

8. Other special conditions;

Notes on using the angle head

1. Generally, the angle head adopts non-contact oil seal. If cooling water is used in the processing process, it needs to run before spraying water, and adjust the direction of the cooling water nozzle so that it sprays water toward the tool, which can prevent the cooling water from penetrating into the body. risk to prolong life.

2. Avoid continuous processing at the highest speed for a long time.

3. Refer to the parameters and characteristics of each type of angle head and use it under appropriate processing conditions.

4. Before use, it is necessary to confirm the test run for a few minutes to warm up the engine. For each processing, it is necessary to select the appropriate speed and feed for processing. The speed, feed and depth of cut during machining should be adjusted in a progressive manner until maximum machining efficiency is achieved.

5. Generally, when processing standard angle heads, it is necessary to avoid materials that will produce dust and particles (such as graphite, carbon, magnesium and other composite materials, etc.).
