Achieves high-quality microprocessing with reduced thermal damage. Suitable for processing brittle materials such as difficult-to-cut materials, ceramics, glass, and films.
Ultrafast pulse laser processing is a method of fine machining using lasers with short pulse widths (such as picoseconds and femtoseconds). Ultrafast pulse lasers have minimal thermal effects and result in high-quality finishes. They achieve high-quality results even on brittle materials such as ceramics, glass, silicon, and films. Additionally, with a unique taper angle control feature, it is possible to process arbitrary hole shapes with high precision, allowing for customization according to customer requirements. Features: Our ultrafast pulse laser processing has the following features: - Non-thermal processing using femtosecond lasers reduces burrs and microcracks, enabling high-speed machining. - High-quality processing of difficult-to-machine materials such as hard metals, ceramics, glass, and silicon. - Processing with taper angle control allows for the realization of arbitrary shapes, including straight holes, reverse taper machining, and holes of shapes other than round. - Large stage capability for processing large workpieces (maximum work size: 500mm square) can meet demands for fine and precise machining on large workpieces, such as applications requiring adhesion to the stage. *You can view service introduction materials that showcase processing examples by downloading the PDF.

basic information
**Principle of Ultrafast Pulse Laser Processing** Ultrafast pulse laser processing is a method that decomposes and vaporizes the processing surface (ablation processing) by applying high peak power over a short period. Unlike thermal processing, which involves melting and removing materials, this method achieves processing with minimal thermal damage, resulting in a high-quality finish. **Processing Specifications** Minimum hole size: Straight hole φ25μm (also compatible with taper and reverse taper) Surface roughness: Ra 0.1μm or less Hole accuracy: ±10% or less Processing thickness: 0.7mm (based on our track record) Aspect ratio: 7 times (based on results from straight holes) In addition, we combine our long-established precision microfabrication technologies (machining, electrical discharge machining, grinding, and lapping) with metal 3D printing to support your company's problem-solving needs. If you are struggling with product finishing, please feel free to consult us.

Company information
Precision micro-machining technology is increasingly recognized as a common foundational technology that supports modern advanced industries. Since its establishment in 1955, Toray Precision Co., Ltd. has manufactured spinnerets, which are key technologies for synthetic fiber production, and has contributed to the development of the synthetic fiber industry by providing them to fiber manufacturers worldwide, including Japan and Europe and the United States. Meanwhile, the experience and technology gained during this time in precision micro-machining have been widely applied to other industrial sectors. Precision machined components are incorporated into critical parts of aircraft, industrial robots, measurement and control equipment, etc. Additionally, the specially developed and designed fluid nozzles have demonstrated their functionality as important components in various industrial machines. The ultra-precision micro-machining technology, boasting sub-micron precision, is also utilized in the optical communication field, which is essential for realizing a highly information-oriented society. We have also commercialized various optical devices, including optical components such as ferrules and adapters. As a pioneer in ultra-precision micro-machining technology, we will continue to contribute to society by delivering high-precision, high-quality products.
