Carl Benzinger Lathes:
Precision Engineering for
Advanced Manufacturing

Company Overview
and History
Founded in 1916, Carl Benzinger began as a manufacturer of turning and milling machines in Pforzheim, Germany, initially serving the jewellery and watchmaking industries. By 1941, under the management of the Jehle family, the company transitioned into CNC lathe production, establishing itself as a leader in high-precision machining.
Today, Benzinger operates as a globally recognized organisation, specializing in ultra-precision CNC lathes and milling machines for industries such as medical, aerospace, automotive, optics, and watchmaking.
Benzinger’s philosophy centres on German-engineered quality, modular machine design, and customer-specific automation solutions, ensuring maximum productivity and unmatched precision.

Why We Do What We Do
I would like to say thank you for your assistance so far. We have only drilled 4 x 0.80mm holes 50d deep but the fact they worked the first time was appreciated by everyone.
We use OSG mainly but when we have a specific job that needs doing, we come to Rainford Precision because they are and do the Crème De La Crème of Products and services.
The End Mill was an ideal choice due to the unusual shape and the need to have a small radius. They turned out great, and the surface finish is really good.
I would like to say thank you for the help you have given our project over the last few years. Your advice on the correct cutters plus the right speeds and feeds has not only helped with accuracy but brought the cycle times down so we can meet our project deadlines.
Thank you for making that so incredibly easy and prompt.
We received your delivery this morning as you had promised to do for us, thanks for that, it is great when a plan comes together.
A diamond service from Rainford as usual. The success of our company is very much down to the external support received from Key organisations such as Rainford Precision. Your company is one of the first I will always turn to assist us.
