Swiss screw machining and turning comprises a large part of our high precision machining business at Ardel Engineering and Manufacturing. Swiss Screw Machines are different from other types of CNC Lathes or turning machines because they minimize the distance between the workpiece support (main spindle) and the cutting tool through the use of a guide bushing. This contrast from traditional turning reduces workpiece bending, thereby eliminating deflection at the cutting surface. The Swiss machining process is ideal for precisely manufacturing high volumes of small cylindrical pieces.

Swiss Turned Parts

At Ardel, we can accommodate parts made from almost any type of metal, plastic, or engineering grade material up to 32mm (1.25 inches) in diameter. The magazine style bar feeders of our Swiss CNC lathe machines allow continuous operation and efficiency by holding raw rod stock up to 12’ in length. The twin spindles of our machines also enable versatile secondary operations to create multiple part features within the same cycle.

Ardel Swiss machine tooling is optimal and economical for producing components in quantities between 500 and 50,000 units, though our team can also produce orders above or below this range. Our highly experienced engineers will work with customers to advise them on the best manufacturing method for their specific application and the particular geometry of their part.

Additional Services Offered

The typical lead times for our prototyping and production processes are 2 to 3 weeks, and 4 to 6 weeks, respectively, with rush and emergency services also available. In addition to these primary design and small part machining capabilities, Ardel provides secondary processes for parts including, but not limited to:

  • Heat treatment
  • Electroplating
  • Passivation
  • Anodization
  • Laser Part Marking

We believe that screw machine companies should offer turnkey solutions to customers, as well as built-to-order, high precision parts. At Ardel, we work with certified subcontracted vendors in a number of secondary processes to ensure that you receive completed custom machined parts with the exact specifications you need.

ISO & ITAR Certified Swiss Screw Machining

Ardel is proud to be ISO 9001:2008 certified and ISO 13485 compliant, allowing us to give customers complete confidence in our control over materials and processes. We use electronic communications across departments, from designs, to emails, to accounts payable; we have even become completely paperless with some customers. Our testimonials show that Ardel is a trusted partner who delivers quality and satisfaction on every job.
