Extremely small precision parts and products that cannot be confirmed in detail with the naked eye.

The definition of microfabrication, when we think of the term, typically brings to mind extremely small precision parts or products that cannot be observed in detail with the naked eye. Indeed, that is not incorrect. For instance, when performing shape processing with a φ0.1mm end mill, it is obvious that due to the extremely small size of the parts, the clamping, tools, measurement, finishing, and packaging cannot be the same as those used for general sizes (which can be accurately recognized by the naked eye). Specialized clamping fixtures, tools, extremely small measurement clamps, and non-contact measuring devices are required for all processes, using jigs that are not commercially available or measuring instruments that are not typically used in standard processing. In this way, when everything from tools to equipment differs from the general ones, and the product itself is extremely small, it is also referred to as microfabrication.

basic information

**Definition of Microfabrication** - Extremely small precision parts or products that cannot be confirmed in detail with the naked eye. [Microfabrication is also expressed when the product itself is extremely small.] - Requires the use of specialized clamps, tools, and extremely small measuring clamps, as well as non-contact measuring instruments that are not commercially available for all processes, or measuring instruments that are not used in standard processing. [Products with partial microfabrication are expressed as having parts that are extremely small microfabrication.] - Clamping is done with general vises or jigs. - Tools typically use both standard tools and micro tools. - Measuring instruments combine three-dimensional measuring machines, microscope measuring instruments, and image measuring instruments for measurement. - Methods other than cutting, such as die-sinking electrical discharge machining, wire cutting, and polishing machines, are also used. **Definition of Precision Machining** - Precision machining refers to the processing of parts where the grade of general tolerances (especially dimensions without tolerance indications) is set to a high level based on Japanese Industrial Standards (JIS). - The difficulty varies depending on material, size, and shape, which significantly affects product quality based on processing methods, equipment, and the skill of the technicians. - Processing that requires high precision is what is defined as precision machining. ● For more details, please contact us or refer to the catalog.
