The function of the engraving machine tool holder.

The milling process directly achieves perfect finishing and perfect quality, which was unimaginable before. However, with the design and tools of modern machine tools, this has become a trend in the industry. In more and more precision machining applications, there is no need for grinding, polishing, or etching after milling. In these applications, the engraving machine tool holder system plays a significant role. It ensures tool rotation accuracy, compensates for vibrations, and guarantees precision on the geometric reference surface and perfect surface quality. Now, let's learn about the role of the engraving machine tool holder!

Whether in the watch industry, mechanical manufacturing, or medical technology, as long as it involves machining, people are seeking effective ways to optimize processes. Especially manufacturers using ultra-precision machining technology are pioneers in this area, where the engraving and finishing work on the machined surfaces are done manually.

The engraving machine tool holder, in conjunction with air bearing spindles and ultra-fine balance Schunk TRIBOS triangular tool holders, can achieve very good results during the coin pressing process.

Mirror polishing that meets precise geometric standards

Today, the quality level achievable in precision machining impresses even experienced users. Typically, processing quality depends on the levels of etching, grinding, polishing, and laser processing. Higher processing speeds bring greater economic benefits. Series tests on ultra-precision machining induced by static gas surfaces conducted at ETH Zurich show that the surface quality of each milling pass is at Ra 25 nm level, while the surface milling quality is at Ra 3 nm level. These two quality grades not only correspond to polished surface quality but also meet high-precision geometric standards. Previously, the injection molding of high-gloss plastic parts required milling followed by complex processes for polishing. With modern precision machining processes, extremely smooth surfaces can be produced directly. Non-ferrous metals perform even better: using diamond tools, milling alone can achieve mirror-polished surfaces with accurate geometric shapes suitable for precision applications like laser optics. This technology has many advantages. It significantly shortens finishing time while avoiding the convex surfaces and rounded edges produced during grinding and polishing.

Non-wear clamping

Common tool holding systems like spring collets and heat-pressed collets cannot perform such demanding machining tasks. Even after thousands of clamping setups, the material does not fatigue. Additionally, it has excellent vibration reduction capabilities. Using hydraulic chucks, tool changes can be completed in seconds with a simple clean-up, ensuring process stability. Depending on the type, all tool holders suitable for h6 quality grade at a speed of 205,000 rpm have been tested. These tool holders can also clamp or change tools with a diameter smaller than 1 mm while maintaining process stability, reducing vibration damage during heavy cutting.

The engraving machine tool holder plays a dual role in five-axis machining.

For high-precision 5-axis machining, the engraving machine tool holder can effectively alleviate vibrations during the machining process, providing strong support for extended piston rods with minimal profile interference. The combination of rotational accuracy and damping performance protects the tool edge, extends tool life, and provides excellent workpiece surfaces. A simple manual clamping device is sufficient, and the entire clamping process can be completed in seconds. These clamping devices require no maintenance and are insensitive to impurities.
