Beijing Jingdiao Ultra-precision Grinding Center
Beijing Jingdiao Technology Group Co., Ltd. (Beijing Jingdiao) is a privately owned company engaged in the research, development, and manufacturing of precision CNC machining centers. The core products are five-axis ultra-precision machining centers, which are characterized by the ability to consistently achieve "0.1-micron feed, 1-micron cutting, and nanometer-scale surface finish." Upon this technological capability, Beijing Jingdiao has newly developed ultra-precision grinding centers. These machines enable ultra-precision grinding of brittle materials (such as glass, ceramics, silicon, and gemstones) as well as difficult-to-machine materials (including cemented carbide, stainless steel, and titanium alloys).

The world is pushing forward with the intorduction of renewable energy to achieve "carbon neutral"as many companies management are facing to focus on decarbonization.
All production facilities require new technological innovations to reduce CO2 emissions, as well as greater efficiency through automation, labor savings, and process consolidation. Furthermore, products need to be optimized to be lighter, more compact, more precise, and stronger by adopting new materials and structures.
We will support and advise the cutting-edge method with our machine where such innovation is required.
013D Additive Manufacturing
Lattice Structure
Topology Optimization
Additive manufacture approach for the complex three-dimensional shape, lattice and for multi-layer structure. We provide one stop service solution from annealing , drying and to the inspection for fast lead time and low production cost.
02Sand mold 3D printer
Sand mold (main mold and core) sample
Sand lamination process
Main unit model AJS1800A
"KOCEL Sand Mold 3D Printer" will dramatically channge the process of the sand molds for casting.
The definition of "complex shapes" and the "main mold and core" can be produced directly from the 3D model.
There will be no need for making wooden patterns, which result to have no equipment to make wooden patterns.
We are willing to provide proposals for the equipment ,silica sand, and resin, which are cost-effective to meet your needs.
