The Swiss Chuck power chuck allows for quick change of jaws using spherical positioning pins. There is no need for regrinding even after reattaching the jaws.

The precision power chuck KCHP/VKCHP was developed for cylindrical grinding machines. To achieve long service life, the chuck is designed to be dustproof (sealed), and it is permanently lubricated by internal oil. These features have nearly realized maintenance-free operation. The new precision power chuck KCHP/VKCHP is equipped with functions to prevent unnecessary oil loss and coolant intrusion. KCHP can operate with a hydraulic drawbar and can also be activated by an air cylinder mounted on the spindle side. VKCHP operates through a rotating air tube that passes through the spindle, eliminating the need for an air cylinder. Quick change of jaws with micron-level tolerance has been achieved. All power chucks KCHP/VKCHP allow for quick jaw changes using spherical positioning pins, which means that there is no need for regrinding even after removing the jaws from the chuck.

Thanks to its advanced mechanism, it can evenly grasp irregularly shaped workpieces! A high-precision chuck designed so that force is not applied until it securely grips at the correct position.

The Swiss chuck (formerly Forkart Swiss) compensation chuck OVEKA/KA has been developed for crankshaft machining and has a proven track record. After several years, this chuck has been further improved to accommodate all types of shaft machining. These chucks are designed to apply no force until the workpiece is securely held in the correct position. Thanks to the advanced compensation mechanism, they can evenly grip workpieces that are not perfectly round. Designed compactly, they effectively utilize the distance to the center. Therefore, the compensation chuck OVEKA/KA can be considered the optimal chuck for grinding operations using a center. In an environment where stable machining is required, the Swiss chuck's compensation chuck features a sealed structure to prevent contamination. The hydraulic drive type OVEKA is equipped with a patented lubrication circulation system. Since the internal components of the chuck are always lubricated during gripping, it achieves maintenance-free operation, extending the chuck's lifespan and reducing costs.

This is a diaphragm chuck from Swiss Chuck (formerly Forkart Swiss). It adopts a zero-point system to achieve high repeat accuracy of the jaws.

In recent years, grinding machines have required holding devices that can fully utilize the machine's performance and enable efficient production. When it comes to precision chucks, nothing surpasses Swiss chucks worldwide. We have built a foundation of innovative technology in collaboration with renowned machine manufacturers. As a result, Swiss chuck products offer the highest level of precision, providing reliability and flexibility for applications. The air-driven diaphragm chuck 6VMCHP guarantees a repeatability precision of less than 2μm. During gripping, the retracting function ensures a firm contact with the end stop, allowing for precise machining under strict accuracy. It is also possible to perform coolant or air blow through the through-hole, and seating confirmation is available. The pneumatic rotary tube can be directly screwed into the chuck through the spindle interior.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly creating sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be created in a single molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
