Tech­nologies and Services

From the right choice of the material over the feasibility of turned and milled parts to the assembly of entire components and even beyond, H & W Quadflieg advises you in a competent and exhaustive way. It is very important for us to support you in making your ideas and projects become workable and cost-efficient.

Tech­nologies and Services

CNC-­Ma­chining Tech­nology

We combine turning and milling technologies in one go on our turning/milling centres. Thus we achieve maximum shape and position tolerances for all machinable materials. Even free-form surfaces in hardened materials are part of our daily business.

CNC – Turning Tech­nology

Where our competitors will simply walk away due to the requests for highest complexity and accuracy, H & W Quadflieg manufactures high-precision turned parts for you, starting from a diameter of 3 mm up to a diameter of 600 mm and up to one meter in length.

With its high-quality, cutting-edge machine park, H & W Quadflieg accomplishes reliably even the most challenging requirements in order to produce complex CNC turned parts that require utmost accuracy and precision.

Thanks to our wealth of experience from 60 years of tradition, H & W Quadflieg manufactures small and medium-sized series from 5 to 5000 pieces for you. With our high-quality, state-of-the-art machine park, we process workpieces based on almost all machinable materials. The processing of hardened materials is our excellent competence.

CNC – Milling Tech­nology

H & W Quadflieg manufactures highly complex milled parts for you, starting from a few grams up to 250 kg. For complex CNC milled parts that demand extreme accuracy and precision, H & W Quadflieg uses 5-axis CNC machining centers. We mill free-formed surfaces 5-axis simultaneously and can also measure them. Form and position tolerances on 0.01 mm are our daily business. In addition, the H & W Quadflieg team is very experienced in milling hardened materials. H & W Quadflieg manufactures small and medium sized series from 5 to 5000 pieces, with a component weight starting from a few grams up to 250 kg with almost all machinable materials.
