During machining on three-axis machines, side operations (such as milling, drilling, and tapping) often increase the number of workpiece setups or require machine upgrades. For workshops primarily operating three-axis machining centres, achieving multifunctional machining without additional capital investment has been a key direction in our product development.
Today, we provide a detailed introduction to the Angle Head Holder.
What Is an Angle Head Holder
An angle head holder is an accessory device for machining centres. Our products are compatible with BT, BBT and other spindle interfaces. Through an internal gear transmission structure, the spindle’s rotational direction is changed to 90° or another fixed angle, enabling lateral power output.
The basic working sequence is: spindle power input → internal gears change the transmission direction → power output perpendicular to the spindle axis → side machining operation.
With this structure, the machine can complete side or angled machining operations without the need to re-clamp the workpiece.
Core Advantages of the Angle Head Holder
- Increased machining flexibility.
- Reduced clamping errors.
- Lower equipment investment costs.
- Improved machining efficiency.
Typical Application Scenarios of the Angle Head Holder
Side drilling and tapping of box-type components, side-wall milling of mould cavities, multi-face hole machining of structural parts, lateral cutting inside deep cavities, and machining tasks where equipment space is restricted.
Engineering Limitations of the Angle Head Holder
Although the angle head holder offers clear advantages in flexibility, its application range must still be carefully considered. For example, the transmission structure limits the maximum torque, making it unsuitable for heavy-duty cutting with large depths of cut. The output speed is typically lower than the main spindle speed. Internal gears will experience wear over prolonged use and require proper lubrication and maintenance. Extended overhang structures may also affect rigidity.
Therefore, for high-frequency multi-face machining or high-load conditions, four- or five-axis machining centres remain the more stable choice. However, when the objective is to minimise overall costs, the angle head holder remains a highly effective solution.
In modern machining environments, the angle head holder provides three-axis machining centres with a relatively high degree of flexibility. Through proper use of the angle head, workshops can achieve multi-face machining and side cutting without investing in larger equipment, significantly improving production efficiency and machining consistency.
As a manufacturer of angle head holders, we develop and optimise our products based on real machining conditions. We are able to provide matching structures and specifications according to different operational requirements, helping customers maintain machining quality while achieving long-term, stable improvements in production efficiency.
