Solution

High Vibration Damping and Dimensional Stability from a Symmetrical Design

High Vibration Damping and Dimensional Stability from a Symmetrical Design

The CW Series uses high-strength cast iron and a fully symmetrical left-right layout with reinforced rib structures to secure sufficient cross-sectional area and high rigidity. This design makes lateral vibration difficult to transmit, so under normal machining conditions, vibration has little effect on the machined surface. This structure is being analyzed and evaluated through joint research with Nihon University and Fukushima Prefecture, and experimental data has confirmed its excellent vibration damping performance. In addition, the symmetrical structure stabilizes thermal movement and reduces dimensional changes caused by temperature variation. This ensures stable dimensional accuracy even during long-term operation and mass production.

P Series High-Precision CNC Lathes for Micro Machining

P Series High-Precision CNC Lathes for Micro Machining

The P Series are high-precision CNC lathes developed for micro machining. They achieve excellent surface roughness at the Rz sub-micron level in aluminum facing, making them suitable for high-precision components such as lenses and mirrors, as well as other applications requiring superior surface quality. With a rigid, thermally stable structure, the machines provide stable precision machining. The P Series is also widely used in automotive mass production lines, offering the reliability and durability required for 24-hour operation.

High-Rigidity Design for Hard Turning on Hasegawa Lathes

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

J25 & C24 – High-Precision, High-Rigidity Compact Lathes

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

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.

Reuse of Existing Collets (Compatibility Support)

Reuse of Existing Collets (Compatibility Support)

At Hasegawa Machine Works, we strive to ensure that customers can continue using their existing collets whenever possible.
By checking the collet model or an actual sample, we can recommend the most suitable machine compatible with your current collets.
Even if the collet manufacturer has already discontinued production, compatibility is often still achievable.
However, certain sizes or special specifications may be difficult to support.
In such cases, we will propose alternative collet systems or the most suitable configuration, helping minimize your initial investment while ensuring smooth installation and high productivity.

Automatic processing line

Automatic processing line

With both CNC lathes and machining centers in our lineup, Hasegawa is able to propose solutions that consider the entire machining process.
We are quick to respond and highly flexible with customization. By handling as much as possible in-house—such as multi-joint robots, parts feeders, automatic measurement systems, and polishing units—we significantly reduce engineering time and after-service workload. This also improves the efficiency of our support services.
Our team includes specialists in gantry loaders, robot teaching, and electrical control, with extensive experience in multi-machine production lines for automotive manufacturers.
Hasegawa machines are compact and low in height, making them easy to automate with robots and gantry loaders. These strengths have helped many customers improve productivity and profitability.
Please feel free to contact us for automation or process improvement inquiries.

Vibration cutting (spindle oscillation)

Vibration cutting (spindle oscillation)

Oscillation Cutting (Vibration Cutting)
Reliable chip control even on Hasegawa’s compact machines
Oscillation cutting synchronizes periodic X and Z axis vibration with spindle rotation, breaking chips into smaller pieces. By introducing a brief non-cutting interval, chip entanglement and evacuation issues are reduced. Amplitude and cycle settings can be easily adjusted in the program.
Key benefits include reduced chip tangling, more stable deep-hole and small-diameter machining, improved tool life, and fewer issues during unmanned or night-time operation.
Despite being compact, Hasegawa machines maintain the rigidity, control response, and synchronization accuracy required for stable oscillation cutting. The structure also incorporates chip evacuation considerations, delivering performance comparable to larger machines.
Users have reported improvements such as eliminating deep-hole clogging, more stable night-time operation, and extended tool life on difficult-to-cut materials.

Collaborative Robot Packaging System

Collaborative Robot Packaging System

Collaborative Robot Packaging System
Hasegawa’s collaborative robot package uses a vision camera to capture reference points of the workpiece, enabling automatic position correction. Even if the cart is moved to another machine, the system can easily restore the original alignment.
This flexibility allows smooth adaptation to layout changes or machine replacements, making the production line highly expandable.
In addition to pallet handling, the system supports various workpiece shapes through multiple end-effector and feeding options, allowing us to propose the optimal automation setup for each product and process.
This robot system greatly contributes to manpower reduction, standardized operations, and shorter setup times.
