High-Rigidity Design for Hard Turning on Hasegawa Lathes
Hasegawa lathes are engineered with high rigidity to support hard turning of high-hardness materials such as HRC60-class steel.
Despite their compact size, the use of cast-iron main structural components provides excellent vibration damping and stable machining accuracy.
In addition, the gang-type lathe structure positions the tool lower relative to the slide,
resulting in higher rigidity than it appears and enabling strong cutting forces required for finishing operations.
The machines support a wide range of machining methods, including dry cutting and wet cutting with coolant.
They are also compatible with CBN and ceramic tools, making them ideal for hard turning and high-precision finishing of high-hardness materials.

J25 & C24 – High-Precision, High-Rigidity Compact Lathes
The J25 and C24 deliver micron-level machining accuracy in compact machine frames.
HASEGAWA’s unique thermal-stability design—optimized heat-source layout, symmetric structure, and a high-damping cast-iron bed—minimizes thermal displacement and significantly reduces correction and adjustment work.
With a high spindle surface speed, the machines are fully capable of hard turning, making them ideal for finishing high-hardness materials up to HRC60.
They can be easily integrated with automation systems, making them suitable for mass-production environments.
The hand-scraped double-V slideways and HASEGAWA’s original mechanical structures ensure long-term accuracy retention and outstanding rigidity.
Despite their compact footprints, the machines use high-quality cast-iron bases, achieving excellent damping and stability for both precision machining and volume production.
Thread Whirling for High-Hardness Materials
At Hasegawa Machine Works, we perform high-precision, stable thread whirling on HRC60-class hardened steel using our proprietary patented holder.
This technology is particularly effective for fine tooth profiles of module 2 or smaller, achieving machining quality that is difficult to obtain with conventional holders.
We have extensive experience machining high-hardness, high-precision components such as ball screws and worm shafts.
By integrating our expertise in process consolidation and automation systems, we can support stable unmanned operation and reduced cycle times.
If you are considering improving finishing processes or tooth profile machining for high-hardness materials, please feel free to consult Hasegawa Machine Works.
