Shenzhen Liantejia Precision Technology Co., Ltd. is an enterprise specializing in precision processing and manufacturing of superhard alloy and ceramic materials. It was established in 2010. The processed products have extremely high manufacturing accuracy (up to ± 0.1 μm) and detection reliability. In 2010, we took the lead in controlling the batch accuracy of tungsten steel precision shafts with a diameter of less than 0.1mm within ± 0.5 μm, and in 2020, we advanced it to within ± 0.1 μm. Machinable materials also include tungsten steel and nano-ceramics. Because of the specialty, the original unreachable machining problem has become accessible.
