Long Shaft Parts-New Process Total Solution for “Hao” Machining

The technical content of turning long shafts is relatively high, and turning thin shafts is especially difficult. The use of clamping methods and the use of more general methods will make the processing more difficult, and the workpiece is easily deformed during the processing process and may not be completed. Generally speaking, long axis parts require high dimensional accuracy, shape accuracy (cylindricity) or surface roughness. In order to meet these precision requirements, traditional processing is used, which has low productivity, complex processes and high equipment costs. Hawker’s mirror processing equipment has a new process called “Hao”, which uses a lathe instead of grinding, and it is easy to achieve long-axis mirrors in one setup.

After the Hokkonen process. It can handle the Miller effect of long-axis workpieces (surface roughness Ra value <0.2 μm). The surface hardness of the workpiece is increased by more than 20%. It solves the problem that the machining accuracy of long-axis parts (using elastic mandrel, tool holder, zero force mechanism, etc.) is difficult to guarantee. The wear resistance and corrosion resistance of the workpiece are improved by more than 50%. After the surface of the workpiece is strengthened, its fatigue life can be extended several times. Extend the service life of compatible sealing rings. High efficiency, environmental protection, energy saving and high quality.

Hokkonen process overall solution 1

Rough machining -> Fine cutting -> Hakone machining
After the shaft was roughly rotated on the lathe, Hokening’s machine became “How”.
This solution can be used for optical axis workpieces with high precision requirements, and can also be used for workpieces with very high roughness requirements (short step workpieces). The customer upgraded the traditional processing technology of the lathe.

Hokkonen process overall solution 2

Rough machining -> Rough grinding -> Hokkonen machining
After the rough turning of the lathe is completed, the machining grinder completes the rough grinding, and the Fokening machine tool completes the “hao”. This solution can be used for workpieces (or short workpieces with stepped shafts) that require very high accuracy and roughness. For the existing lathe, it is an upgrade to the traditional processing technology of the grinder.

Hokkonen Process-Whole Solution 3

Roughing -> Refining -> Hoknin processing
All machining is done in one setup using a compound Hokkonen lathe. This solution is suitable for processing optical axis workpieces (even short-step shaft workpieces), and has very high roughness requirements while still having high precision requirements.

Hokkonen Process-Whole Solution 4

Roughing -> Fine Cutting -> Roughing -> Hokkonen Machining
It is processed in one setup by a fully loaded Hokkonen compound car. This solution is suitable for optical axis workpieces with very high machining accuracy and roughness requirements (also for machining short-step shafts).

Hokkonen full process solution 5

Rough machining -> Fine cutting -> Hakone machining
All shaft machining is done with a single fixture using a composite Hokkonen lathe. However, this machine has an additional axis dedicated to controlling the Hokkonen tool, which can complete the machining of slender shaft workpieces in one setup.
