The broaching tools manufactured by the German company HORN, handled by IZUSHI, enable process integration and high-precision machining. Since they can process keyways and other features using NC lathes and machining centers, there is no need for setup changes, saving effort and time. Furthermore, with internal lubrication, they demonstrate excellent chip removal performance and can achieve high-quality key width precision. There are cases where switching from dedicated machines to using broaching tools on multi-tasking machines has reduced cycle times from 50 minutes to about 20 minutes, a reduction of approximately 60%. 【Features】 - Stable machining and finishing surfaces achieved with internal lubrication holders - Standard lineup of cutting edge shapes for general machining and broaching units - In addition to keyways, compatible with hex holes, square holes, Torx, and spline gears (special items) 【Processing Precautions】 * A spindle lock function is essential. * For blind holes, please include a relief groove at the inner diameter's depth. Without a relief groove, there is a risk of chip clogging and cutting edge damage. 【Specifications】 System 105: Pilot hole diameter φ6.0mm and above System 110: Pilot hole diameter φ9.0mm and above System 117: Pilot hole diameter φ14.0mm and above

This time, the cutting report introduces the new I Breaker product. Processing was done using SC420, which is prone to long chips. The I Breaker is a new breaker for the Mini System 108. It excels in chip management performance even at low feed rates with materials that tend to produce long chips. The finished surface after finishing processing achieves a high surface quality. For more details on processing and chips, please watch the original explanatory video. *You can view detailed content of the column through the related links. For more information, please feel free to contact us.

This time, the cutting report introduces the new PT breaker. Processing was done using SC420, which tends to produce long chips. The PT breaker features a two-corner insert with a 50° cutting edge that has not been part of our lineup until now. It is an ideal tool for turning (front cutting) and back turning (rear cutting) on Swiss-type automatic lathes, and the processing video demonstrates excellent chip management. *For detailed content of the column, please refer to the related link. For more information, feel free to contact us.

The broaching unit is a unit that achieves the efficiency of keyway and spline processing, enabling high-speed machining. It is suitable for medium to large-scale production. The features (for lathes) include a maximum cutting frequency of 1,500 cuts/min (at 3,000 rpm) and a maximum feed amount (per stroke) of 0.02 to 0.10 mm. Additionally, the effective stroke lengths are 32 mm and 51 mm. *For detailed information about the column, please refer to the related links. For more information, feel free to contact us.

Introducing the significant reduction in work time with the interchangeable tool "W&F Micro." Features such as "tool presetting outside the machine," "head exchange while the holder remains attached to the machine," and "the head is secured with just one screw" are highlighted, along with illustrative images. Additionally, we also present the lineup of holders and heads. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.

This time's cutting report (Kezurepo) involved groove cutting processing and a comparison of surface roughness using tools from HORN and other manufacturers. The work material was low carbon steel S25C, processed with cermet and carbide. Low carbon steel can be prone to chipping and may present challenges in achieving surface roughness. However, there are suitable breakers and tools that allow for stable processing even with low carbon steel. Please take a look at the test results. *For detailed content of the column, you can view it through the related links. For more information, please feel free to contact us.

This time, the cutting report (Kezurepo) is a mini-series where we conducted internal threading machining and compared the processing of "with breaker" and "without breaker." The workpiece material is S45C, and we used HORN's System 111 inserts for both. The inserts with breakers were newly developed in 2019, but at that time, they were only available for Systems 108 and 114. This year, Systems 111 and 116 have been newly added. Please pay attention to how the "chip removal" changes depending on the presence or absence of the breaker. *For detailed content of the column, you can view it through the related links. For more information, please feel free to contact us.

This time, we conducted a comparative test using the 6-corner insert system 64T. The materials being machined were S45C, and we performed grooving operations using tools from three companies: HORN, Company A with multi-corners, and Company B with multi-corners. We compared chip removal performance and machining time. This is a must-see for those who are struggling with inserts that have many corners, as well as with chip removal and machining time. Additionally, we have created an original interview video about this machining process. Please take a look at the features of the system 64T and the machining video. *For detailed content of the column, you can view it through the related links.

This is a cutting report. The material being cut this time is SCr420, which is commonly used in automotive parts processing. SCr420 is an alloy steel with ductile properties, and sometimes it can be difficult to process. We conducted a comparison test of high-feed groove machining and chip generation using three types of breakers from HORN, with two patterns of plunge feed. The key point is that "high feed is possible" with SCr420, so please pay attention to the chip fragmentation. With the appropriate breaker, we achieved fine and uniform chips. If you are struggling with chip elongation, please use this as a reference. *For detailed content of the column, you can view it through the related links. For more information, please feel free to contact us.

The material being machined this time is S45C, and we conducted groove cutting using three different types of HORN breakers to compare the surface roughness (Ra) at the bottom of the grooves. The cutting speeds were compared at 180 m/min and 150 m/min, with a depth of cut of 0.5 mm at the bottom of the groove. Each breaker has its own characteristics, and you should be able to see the differences in surface roughness. If you are facing challenges in machining that requires high surface roughness, please refer to this information. The suitable breakers for finishing have produced high-precision results comparable to precision finishing grades. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.

The material being machined this time is S45C, and we conducted a cutting operation using three different types of HORN breakers to compare chip processing. As supplementary information, we also measured not only the chips but also the arithmetic average roughness Ra (μm) and the maximum height of the profile Pt (μm). The machining was done under the same conditions, with an insert width of 2.0 mm, a cutting speed of 180 m/min, a constant peripheral speed, and a feed rate of 0.08 mm/rev for comparison. Each breaker has different characteristics, and I believe you can see the differences in the chips. *For detailed content of the column, you can view it through the related link.
