Frequently asked questions
What is the difference between the GRM 80 and the RM 40?
The GRM 80 is for larger parts: 80 mm strip / 6 mm thickness / Ø 6 mm wire and a 300–400 kN press. The RM 40 handles smaller, faster parts (350 1/min) with 60 mm / 4 mm / Ø 4 mm and a 90–200 kN press.
Will my existing GRM 80 tools run on a new machine?
Yes; GRM-series accessories are compatible across the series, and GRM tools can be transferred to the GRM-NC servo machine.
How are GRM 80 spare parts supplied?
Bihler stocks more than 30,000 original parts; Boztaş delivers customs-cleared via its Ostfildern warehouse.
Can a used GRM 80 be purchased?
Bihler offers GRM 80s modernised in Füssen (new drive, VC1-E control) with a 12-month factory warranty; Boztaş Deutschland supplies them.
