Revolutionising Productivity in Precision Industries

In today's high-precision manufacturing landscape, the aerospace, medical, electronics, and small part processing industries face pressure to maintain tolerances while reducing costs and addressing skilled labour shortages. Sliding head machining technology, especially Swiss-type machines, is essential for producing intricate, small-diameter components. TaeguTec's WINSWISS line and expanded DIA-MILL offerings significantly reduce downtime, lower skill requirements, and enhance manufacturing flexibility.
Here, Ok Soo-Jin (Joy Ok), the Product Manager for Turning at TaeguTec’s world headquarters in Daegu, explores how TaeguTec's cutting-edge tooling systems transform precision manufacturing operations across demanding industries.

The Evolving Demands of Precision Industries
The aerospace, medical, and other critical manufacturing sectors share common challenges with parts that require increasingly complex designs, tighter tolerances, exotic material compositions, and the pressure to maintain quality despite workforce challenges. These industries cannot afford variation or inconsistency in their components; yet, they must simultaneously improve productivity and reduce costs.

"In the miniature industry, accuracy is critical, and during machining, the cutting edge should have no movement at all in the toolholder," says Joy Ok. This fundamental requirement drives TaeguTec's approach to tool design across its product lines, emphasising stability, repeatability, and ease of use.

The WINSWISS Advantage: Modular Tooling Revolution
TaeguTec's WINSWISS line represents a significant advancement in sliding head tooling technology. Unlike conventional monoblock tool holders that dominated the industry for decades, the WINSWISS modular systems offer unprecedented flexibility and precision through several key innovations. “We have an extremely advanced clamping structure, and perhaps the most significant innovation in TaeguTec's WINSWISS line is the unique clamping design with a square fastening structure. Traditional modular tooling systems often use round clamps, which can experience rotational movement during operation, a critical flaw in precision applications.”

"If you check competitor geometry versus our geometry, we apply a unique type of clamping system. The round-type insert is susceptible to rotating movement, but our design type provides exceptional clamping rigidity compared to general round shapes. The head has a square to guarantee alignment in conjunction with the round spigot, which has a whistle notch to pull the head into the square shank, delivering exceptional stability and clamping strength.”

This distinctive clamping geometry creates an interlocking mechanism that dramatically reduces movement during operation. The benefits are immediately apparent in performance testing, where customers consistently report superior accuracy compared to competitive modular systems. For aerospace and medical applications, where tolerances can be measured in microns, this stability can mean the difference between acceptable parts and costly scrap.

Quick-Change Capability
Through its intuitive design, the WINSWISS line dramatically reduces setup and changeover times. Unlike conventional systems that require three or four steps to change inserts, TaeguTec's system needs only two simple movements to release and secure components.

“Generally, in the Swiss-type machining arena, only one operator manages multiple machines. If they spend time on setup, changing the workpiece, or filling the barfeed, they want to minimise that time. Thus, the first thing customers request is a convenient, quick-change tool," adds Joy Ok.
This convenience factor becomes increasingly important as manufacturers face skilled labour shortages. The ability to quickly change inserts with minimal training enables companies to maintain high productivity levels, even with less experienced staff. This quick-change capability can significantly impact overall productivity for medical device manufacturers producing complex components in smaller batches.

Optimised Coolant Delivery
The WINSWISS line also incorporates advanced coolant channel configurations that deliver high-pressure coolant directly to the cutting edge. Unlike competitor designs, where the coolant outlet points may be distant from the cutting zone, TaeguTec's approach positions the coolant distribution point very close to the cutting edge.

"The maximum pressure is 100 bar with our system. We can supply toolholders with or without a coolant channel. However, our coolant channel with its proximity to the tool improves tool life by approximately 20%."
This strategic coolant delivery is especially valuable in aerospace applications, where challenging-to-machine materials like titanium alloys and high-temperature superalloys produce significant heat during cutting operations. Improved chip evacuation and cooling enhance tool life while preserving dimensional stability throughout longer production runs.
Expanding Applications with DIA-MILL for Composite Materials
While the WINSWISS line addresses metal cutting needs, TaeguTec has simultaneously expanded its offerings for the growing composite materials sector with new geometries in its DIA-MILL line.

TaeguTec has recently added new geometries (RCME, RCDE) and higher flute numbers (RDCF) to its DIA-MILL line, engineered explicitly for composite materials machining. The RCME type is a multi-flute router design with a unique cutting edge shape that has been optimised for medium to finishing applications, whereas the RCDE geometry combines the RCME cutting edge with a drilling cutting edge, allowing both drilling and slotting with a single end mill. Completing the lineup, the RDCF range is now available with 6 or 8 flutes compared to the conventional 4-flute designs. This is underpinned by a low helix angle that eliminates delamination and splintering when undertaking finishing applications. The composite-specific DIA-MILL line has exceptional material versatility and provides optimised cutting speeds for different materials, including CFRP and honeycomb structures commonly used in aerospace applications. The recommended cutting speeds for the series can range from 50 to 300m/min, depending on the specific geometry and operation.

These specialised geometries address the unique challenges of composite machining, where fibre pullout, delamination, and poor surface finish can compromise component integrity. For aerospace manufacturers increasingly shifting toward carbon fibre and other composite structures, these tools provide the precision and reliability needed for critical components.

Targeted Solutions for Industry-Specific Challenges
The aerospace sector requires exceptional precision and consistency in production runs. Components must adhere to stringent quality standards, and manufacturers face pressure to decrease production costs and lead times.

TaeguTec's modular systems offer aerospace manufacturers several key advantages, with demonstrated repeatability being a crucial factor. As Joy Ok adds: "Customers in the small parts sector will sample inspect a part after the first-off, then after 100 pieces, then after 1,000 pieces, and then after one month, they check again. For manufacturers that demand this level of consistent performance, precision and repeatability, the WINSWISS outperforms competitors over extended production runs."

The modular design minimises the tooling inventory required to support production. With a single shank that accommodates multiple head types, aerospace manufacturers can optimise their tooling inventory while preserving production flexibility.

Regarding the medical device manufacturing market, it faces unique challenges due to difficult materials, intricate geometries, and strict regulatory requirements. The industry's shift toward smaller, more complex components aligns perfectly with TaeguTec's specialised offerings.
In this sector, TaeguTec tools demonstrate enhanced process stability to support medical manufacturers. The precise clamping mechanism guarantees consistent performance, which is critical when producing medical implants and devices that must meet exacting tolerances.
Additionally, the reduced operator dependency is a huge benefit, as Joy Ok says: "Sometimes the operator just goes, changes the setup, gets the machine running and undertakes another task - and then comes back," notes Joy Ok, highlighting how the WINSWISS tools require less hands-on supervision. This reduced dependency on continuous operator oversight is increasingly valuable as manufacturers struggle with skilled labour availability.

“Medical device production often involves smaller batch sizes and frequent changeovers. TaeguTec's modular quick-change capability dramatically reduces setup times, allowing manufacturers to maintain profitability even with more diverse production schedules.”

Future Innovations
Looking ahead, TaeguTec is exploring the integration of AI capabilities with its tooling innovations. "We also have a plan to develop with AI technology. This forward-thinking approach aligns with Industry 4.0 principles and includes aspects like real-time monitoring with systems that can track tool performance and predict wear before it impacts part quality. There are also automatic parameter adjustment systems where the tools communicate with machine controls to optimise cutting parameters based on actual performance.”
