How much does the Junker JUMAT 3S cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from Junker Group. Configuration moves it a long way.
Overview
The Junker JUMAT 3S is a single-wheelhead CNC grinding machine for parts up to 800 mm long and 80 kg, with a maximum swing diameter of 290 mm. Grinding length and clamping length carry the same 800 mm maximum, and the grinding wheel diameter is given as 400/500 mm.
What stands out is how much capacity sits on a small floor area. Junker gives the footprint as 3250 x 2250 x 2200 mm (WxDxH, without peripherals). The JUMAT 3000, at 3,400 x 2,800 x 2,200 mm, takes up more floor yet lists 400 mm of grinding length and a 15 kg workpiece limit.
The wheelhead versions listed are /10, /10i, /15, /20, /30, /40, 3000/50, /50S and /60. Junker's page gives no machine weight, center height or spindle data for this model, so foundation loading and wheel drive need to be confirmed in the quotation.
