Teflon Tube Die Precision Micromachining Micro Machining is a new sector in JST, but it has developed very fast in the past five years. Most of our micromachining material is free-cutting steel, stainless steel, brass and PTFE, and those components were used in the field of medical device and precision instrument. The smallest tolerance was +/-0.001MM, and our non-standard automatic machine could control the dimensions well. Only if you supply the drawings, we can make these parts exactly per your requirements.
