Toa Seiki Kogyo will exhibit at 'ROBOT TECHNOLOGY JAPAN 2022' held at Aichi Sky Expo (Aichi Prefectural International Exhibition Center). At our booth, we plan to showcase an automatic stage change system fixture. It is suitable for processing a variety of small quantities and for changing stages on a daily basis, as well as for different workpieces. With this specification, it can reduce the costs of expensive robots and teaching. We sincerely look forward to your visit.

Toa Seiki Kogyo Co., Ltd. will be exhibiting at "Mechatrotech Japan 2021," which will be held from Wednesday, October 20 to Saturday, October 23, 2021, at Port Messe Nagoya. This exhibition is one of the largest machine tool trade fairs in Japan, starting in 1987. We sincerely look forward to your visit.

**Publication Content (Excerpt)** ■ Setting TGW Standards and Monthly Error Management Measurements At Toa Seiki Kogyo, we are committed to building a high-level quality assurance system within the company to provide products that meet our customers' requests. As part of this effort, our measurement department conducts monthly error management measurements of inspection instruments. The reference standards used during these error management measurements are exclusively reserved for this purpose to ensure the reliability of inspection results. The process of conducting measurements involves each measurer performing the same measurement with the same instrument, accumulating monthly data for each measurer. This data tracks the individual measurer's error and sensory changes, and is displayed in the measurement room for each measurer to review. By managing this measurement data themselves, each measurer develops a common understanding of measurement errors, resulting in the establishment of a high-level quality assurance system within the company. **Other Publication Content** ■ Achieving Process Consolidation with "Tool Holder in Jigs"! ■ Participated in the VA/VE Technology Matching Fair! ■ Employee Introductions at Toa Seiki Kogyo! *For more details, please refer to the related materials or feel free to contact us.*

【Publication Content (Excerpt)】 ■Introducing the NEW version of the Internal and External Diameter Grinding Machine G Taro! What we are introducing this time is the NEW version of the internal and external diameter grinding machine "G Taro," which we have introduced before. The NEW version adds a magnetic scale to the existing "G Taro," making it more efficient for operations. Previously, the grinding of internal and external diameters was displayed in analog, but by changing it to digital reading, it is now possible to eliminate the hassle of measurement during processing. 【Other Publication Content】 ■We have added three fixed cranes! ■Efficiency improvements through a production management system! ■Employee introduction of Toa Seiki Kogyo! *For more details, please refer to the related materials or feel free to contact us.

【Publication Content (Excerpt)】 ■High-Precision Manual Tightening Jigs for Engine Parts! The jig we are introducing as a production example is a manual tightening jig used for manufacturing engine parts. There are hydraulic and manual tightening jigs, but the jig we are presenting is manual because the workpiece is thin, and applying excessive force can cause distortion. It allows for delicate adjustments of the pressure applied. By producing such jigs, we have achieved a reduction in lead time to complete products in the machining process and improved the precision of hole positions and dimensions. Such manual tightening jigs can also be delivered within 1.5 months from order at our company. 【Other Publication Content】 ■We have introduced Tokyo Seimitsu's 3D measuring machines to our Thai factory! ■We will be exhibiting at the Die Casting Exhibition! ■Employee introduction of Toa Seiki Kogyo! *For more details, please refer to the related materials or feel free to contact us.

**Posted Content (Excerpt)** ■Introduction of Our Air Detection Device What we are introducing this time is the air detection device manufactured by our company. This device is used as a test for confirming the seating of workpieces used in jigs. Traditionally, tests were conducted using only analog measuring instruments, but this detection device is equipped with digital sensors, allowing for direct reading of values. Additionally, it enables observation of finer values. Confirming the seating of workpieces within the jig plays a crucial role in ensuring that the workpiece is properly clamped and does not move during processing. This function allows for the production of high-quality products. If the air detection does not operate adequately, it can lead to significant defects in the products. The air detection device is used by the assembly technician during operation checks after the jig is completed, and it is also used during customer inspections. Being portable, it eliminates delays before inspections, reduces time, and is a highly regarded in-house facility. **Other Posted Content** ■Introduction of OKK Corporation's Vertical Machining Center VP1200 - 30L *For more details, please refer to the related materials or feel free to contact us.*

【Publication Content (Excerpt)】 ■ Please leave the design and production of large processing jigs over 2m to us. This time, we would like to introduce a processing jig that our company recently manufactured for a dedicated machine. This is a large jig that exceeds 2m in total length, and it is a rare manufacturing case for us at this size. It is used in the production line of automotive cylinder blocks and is a product for a certain automobile manufacturer's North American factory. As in this case, our company also accepts the production of large jigs over 2m, and we can deliver using our own trucks or charter services. 【Other Publication Content】 ■ Introduction of 3D-CAD implementation for design enhancement ■ We held a seminar on production technology cost reduction! ■ Introduction of employees at Toa Seiki Kogyo *For more details, please refer to the related materials or feel free to contact us.
