High-precision hole processing with water jet machining.

Overview of Processing Example Product Name: TOMBO No.1995 Irregular Gasket Dimensions: 400W×600L t3 17φ×16 holes This example is an irregular gasket made for large equipment flanges. It features a special contour that combines curved outer edges and straight sections, along with evenly spaced bolt hole processing. By adopting water jet processing, it accurately reproduces complex shapes without the need for molds, achieving both hole position accuracy and outer contour precision. It ensures stable quality from prototype to mass production. Product Features (TOMBO No.1995) TOMBO No.1995 is a general-purpose joint sheet made by blending inorganic fibers and aramid fibers with oil-resistant rubber (NBR). It is suitable for fluids such as water, oil, and brine, and excels in a balance of processability, sealing performance, and flexibility. It is commonly used as gaskets for piping flanges and equipment in various factories across many fields.

Achieving stable seals and cost-effectiveness with high-precision water jet processing.

■Overview of Processing Example Product Name: Clutch Cover Gasket Dimensions: 1.5t × φ355 × φ322 (with P350 holes) This processing example involves the production of a gasket for a clutch cover using D6000 (1.5t). In addition to the outer and inner diameters, the inclusion of P350 bolt holes required simultaneous precision in hole positioning and shape. In this application, "compliance of the joint surface" and "ease of alignment during assembly" are crucial as they directly relate to oil sealing performance. Therefore, the drawing shape was converted into processing data, and the outer circumference, inner circumference, and hole drilling were all processed together using water jet cutting. By processing without affecting the material with heat, the reproducibility of the shape and the quality of the end face are stabilized. As a result, conditions that facilitate alignment during assembly and ensure stable finishing of the sealing surface have been secured. Furthermore, the adoption of D6000 contributes to both practicality and cost advantages for oil seal applications.

In civil engineering sites, workers stand for long periods and move around the site multiple times. Muddy and uneven ground makes walking difficult, leading to strain on the feet and back, as well as an increased risk of falls, so ensuring a stable work path is important. Hyper CLT mats are civil engineering CLT materials that utilize laminated CLT wood. By laying them down in areas such as temporary roads, material storage sites, assembly areas, break areas, and worker pathways, they help reduce unevenness and mud, creating a more walkable environment. They possess surface characteristics unique to wood, providing a walking environment that differs from metal plates. The 5×10 panel weighs about 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce the burden of installation and removal. Additionally, they can be used to address environmental concerns such as glare reduction, noise reduction, and CO2 fixation, as well as measures against heatstroke. They are recommended for creating worker-friendly sites and innovative public works as a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A."

In civil engineering sites, due to the effects of rain and mud, temporary roads, access routes, and heavy machinery work yards can become slippery. To ensure the safety of vehicles and workers, it is important to choose appropriate mats for the site conditions and to improve the footing environment. Hyper CLT mats are civil engineering CLT materials that utilize laminated timber. They possess surface characteristics unique to wood and can provide a non-slip footing environment that differs from metal steel plates. They can be used in a wide range of civil engineering sites, including temporary roads, vehicle entrances and exits, mud prevention, ground protection, heavy machinery scaffolding, and worker pathways. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which contributes to labor-saving in installation and removal. It should be noted that slipperiness can vary depending on weather, slope, mud or oil adhesion, and installation conditions, so on-site verification and appropriate maintenance management are necessary. This wooden mat is registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A" and can be utilized for safety measures and creative ideas.
