Frequently asked questions
How do I choose between the RM 40K, RM 40KS and RM 40P?
Press force and processing travel decide: the RM 40K, with a 90 kN press and 900 mm processing length, is for small parts; the RM 40KS, with a rigid 150 kN press suited to carbide tools, is for parts made from high-tensile steel; the RM 40P, with a separate 200 kN press module and more than 1,400 mm of travel with linear tools, is for sub-assemblies. All three run at up to 350 1/min with a capacity of 4 × 60 mm strip and Ø 4 mm wire.
Will older RM tools run on a new RM 40?
The RM 40K retains the old tool mounting system; RM 35, RM 40 and RM 40E tools fit the new machine's slides, and equipment from older machines is compatible. The manufacturer describes the RM 40KS as fully compatible with the RM series.
What is the difference between the RM 40 and the servo RM-NC?
The RM 40 is a cam-controlled mechanical machine running at up to 350 1/min. The RM-NC is servo-controlled (300 1/min, 200 kN servo press, 4 × 80 mm strip); unit strokes and motion profiles are programmed and settings are recalled from the control. The RM-NC is fully compatible with mechanical RM series tools.
