About us
praecicomps Feinwerktechnik Leipzig GmbH specialises in the manufacture of precision-mechanical components, assemblies and complete devices in contract manufacturing. Production is carried out as single parts as well as in small and medium series, with no mass production. The service portfolio includes CNC and conventional turning, CNC milling, sawing, drilling, thread cutting as well as hard and soft soldering, fine sandblasting and wet vibratory finishing. All work is handled including material procurement and supplementary technologies such as surface finishing, gearing, welding, hardening and grinding; external design services are offered on request. Materials are mainly steel and aluminium. The products are used, among other things, in medical and laboratory technology, analytical technology, biosensor and ultrasound technology, rail vehicle technology, measuring instrument manufacturing, musical instrument manufacturing and watchmaking, as well as by institutes and universities. The company is a registered business in the trade register of the Guild of Precision Mechanics, Engravers and Metal Designers Leipzig and employs 13 staff at the Leipzig site.
