High Precision / Micro Machining Services

China Ceramic machining provides high precision and micro machining services for a wide variety of exotic hard materials. Our well-equipped & maintained facilities combined with our in-depth knowledge and extensive machining experience of hard materials, we manufacture highest quality custom machined parts.

Manufacturing environment	All processes are carried out in climate controlled environment. Anti-vibration countermeasures are taken for the floors.
Equipment	With continuous investment in facilities, machines and equipment are kept up-to-date. To maintain the accuracy, all machines are daily checked and regularly maintained. To maintain the accuracy, all machines are daily checked and regularly maintained.
Tools	Tools are designed by China Ceramic machining and then custom-made by tool manufactures or produced by ourselves. We carry out test machining to elucidate mechanisms of grinding and cutting, and to develop the most suitable tools.
Fixtures / Jigs	We design and make fixtures / jigs if needed.
Staff	We have many highly-skilled and experienced staff. Our education and training programs aim to continuously equip our staff with knowledge and skills.
Machining conditions	With our accumulated machining data, optimal machining conditions for each project can be easily and quickly decided. If needed, we carry out test machining, and then proceed with the actual production based on machining data acquired from the test.
Knowledge of materials	As an expert of hard materials, we are constantly seeking to expand the knowledge about hard materials essential to maintain our high quality precision machining service.
Materials we machine include	Advanced Ceramics, Quartz Glass, Glass Ceramics, Tempax, Silicon, Machinable Ceramics, Metal Ceramic Composite Materials, Molybdenum, Tungsten, Tantalum and etc.
Quality Assurance	Each product goes through inspection by our well-trained staff who have both knowledge and skills required to carry out the inspection properly. All inspection & measuring equipment is daily checked and regularly calibrated to maintain the accuracy. For your special inspection needs, inspections by external inspection organization such as Industrial Research Institute are also available up on request.
