A5052 20mm Sprocket Image Cut Sample The processing of the gear's slit section is done with a width of 1.3mm in a continuous back-and-forth cutting method. In general machining, it is thought that the spacing of the slit section may become uneven due to thermal effects, but it has been completed in a perfectly uniform state. Abrasive water jet is the optimal processing method for applications with high added value and is widely used for cutting aluminum and steel materials. It can cut materials ranging from 0.3mm to 180mm in thickness, regardless of the manufacturing volume. Since it does not undergo mechanical stress and is not affected by thermal deformation or thermal effects, it provides high-quality cut surfaces without stress, making it ideal for the production of test specimens made of metals, resins, etc. Additionally, it saves time and costs that would have been spent on conventional secondary processing, and the setup and jig settings can be completed in just a few minutes, thereby enhancing productivity. Water jet is an efficient and optimal processing method for precision rough machining.

Conductors used in areas where high voltage and large currents flow are employed in various applications such as distribution boards, control panels, and storage batteries. We can respond promptly not only to mass production but also to special sizes of distribution boards and control panels. We cut tough pitch copper with a purity of 99.90% or higher to various thicknesses ranging from approximately 1mm to 100mm and in various shapes as needed. Additionally, while aluminum materials are inferior in conductivity and tensile strength compared to general copper, they are lightweight and are also cut and manufactured for purposes of weight reduction and cost savings.

Ultra-high molecular weight polyethylene (UHMWPE) New Light board 40mm Segmented arc shape cutting processing Multiple arbitrary arc shapes are laid out in numerous segments to efficiently utilize materials, minimizing waste and significantly reducing material costs. We always consider profit assurance and improvement of yield and efficiency, keeping the spacing to a minimum for nesting. In the water jet cutting of thick resin boards, there are two specific issues: water flow delay and taper. However, with Flow's dynamic water jet, high-speed and high-precision taper-free cutting is possible, eliminating heat generation during processing and preventing chips from softening or thermally deforming. The 40mm thick board is processed almost vertically, cutting approximately 20 parts of four types of segmented arcs and fan shapes from a 1000mm x 2000mm board, reducing the conventional machining waste rate from about 50% to below 10%.

Carbon fiber reinforced resin board impregnated with thermosetting resin. With high strength and lightweight characteristics, it is suitable for products in the transportation sector, such as automobiles and aircraft, which require high energy efficiency. In recent years, the introduction of carbon fiber composites in the construction field for seismic reinforcement has also been considered. Although it is an expensive material, low-cost and high-quality recycled CFRP has been developed in recent years. Additionally, there are many composite materials formed and bonded with steel plates and other materials as new structural materials, and the extraction and cutting of test specimens are also being conducted. Carbon fiber reinforced plastics have very poor machinability, leading to various challenges such as tool wear and interlaminar delamination. However, through Yokoyama Kiko's unique technology, such as Reduce Piercing, it is now possible to easily pierce materials that are prone to chipping and cracking during conventional high-pressure piercing, saving time and materials while maintaining structural integrity without causing interlaminar delamination or delamination in the workpiece. It is ideal for cutting lightweight, high-strength materials such as carbon fiber plastics, carbon fiber reinforced thermoplastic plastics, glass fiber reinforced plastics, laminated materials, marble, other stone materials, and glass.

The surface shows some peeling of the protective sheet at the initial penetration point, but the backside can be cut with almost no peeling. The aluminum thick plate is cut using a water jet. Although it is thin, aluminum tends to easily form a natural oxide film when exposed to air, so after a certain amount of prolonged processing, it becomes soaked in water. Therefore, we want to protect as much as possible, except for the cut surface where the base material appears. Of course, with the dynamic water jet, the cutting head is automatically tilted to eliminate taper, reducing water flow delay and taper, allowing for high-precision cutting.

Developed as a substitute for deformed or functionally impaired joints, it is composed of various materials such as ultra-high molecular polyethylene, cobalt-chromium alloy, titanium alloy, and ceramics, each utilizing their unique characteristics. Continuous improvements have been made, enhancing durability with the latest technology, and it is said to have a lifespan of approximately 20 years. The cutting of composite materials showcases the true capabilities of water jet cutting, allowing for verification without applying stress by cutting through the adhesion and voids between materials.

A cost-effective car speaker that incorporates high-performance carbon fiber in the diaphragm. The request was for a complete equal division of the center cut, but due to concerns about the retention rate of each part after cutting, a 90-degree opening cut was proposed. The separated side retained almost its original shape except for the cutting width (cut allowance, kerf width). However, even with the insertion of special stabilizers in the frame (for unstable areas) and in the magnet section, there was still some impact on the interlayer and cutting surface near the cutting width due to the state of jet water flow diffusion after penetrating through the layers, resulting in a lack of clarity and a completely vertical surface.
