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 3000 is a single-wheelhead CNC grinding machine for small parts held between centers: 400 mm of grinding length, a 150 mm center height and a 15 kg workpiece limit. Junker lists it in eight wheelhead versions, /10, /10i, /15, /20, /30, /40, /50 and /60, so the model name fixes the frame and its capacity while the wheelhead is settled separately.
Clamping length matches grinding length at 400 mm, so the whole clamped length of a part can be ground. The envelope is tight in the other directions as well. Peripheral diameter is 150 mm, and the largest grinding wheel the machine takes is 350 mm. These are the figures of a machine meant for light shaft-type parts in series, and a part that is slightly too long or too heavy has no margin to use.
For that capacity the machine itself is substantial. It weighs 12,000 kg and occupies 3,400 x 2,800 x 2,200 mm (W x D x H) without peripherals. A 12,000 kg structure under a part of at most 15 kg puts a great deal of mass behind a small cut, which is what holds size over a long production run. The floor plan still has to allow for coolant, filtration and loading equipment outside the listed footprint.
Two neighbours help place it. The JUMAT 5000 is the bigger frame, at 17,000 kg with 700 mm of grinding length and a 130 kg workpiece limit. The QUICKPOINT 3000 has this machine's 12,000 kg weight and 3,400 x 2,800 x 2,200 mm footprint but lists 500 mm of grinding length.

Strengths & Limitations
Strengths
- Eight wheelhead versions are listed on one frame: /10, /10i, /15, /20, /30, /40, /50 and /60
- Grinding length and clamping length are both 400 mm, so the full clamped length can be ground
- 12,000 kg of machine weight behind a 15 kg workpiece limit
- Takes grinding wheels up to 350 mm in diameter
Limitations
- Workpieces are limited to 15 kg and a 150 mm peripheral diameter
- Grinding length is 400 mm; longer parts need the JUMAT 5000 with 700 mm
- The footprint excludes peripherals, so coolant and loading equipment add to the 3,400 x 2,800 mm floor area
- Junker's table for this model gives no spindle power, wheel speed or control details

Frequently Asked Questions
01
Junker lists 400 mm of grinding length and 400 mm of clamping length, a center height of 150 mm, a peripheral diameter of 150 mm and a workpiece weight of 15 kg. The maximum grinding wheel diameter is 350 mm.
02
Eight are listed: /10, /10i, /15, /20, /30, /40, /50 and /60. The table gives the number of wheelheads as 1. It does not describe what each version contains, so have the wheelhead layout of the version being quoted confirmed in writing.
03
The JUMAT 5000 is the larger frame: 700 mm of grinding length against 400 mm, a 130 kg workpiece limit against 15 kg, a 500 mm maximum grinding wheel against 350 mm, and 17,000 kg of machine weight against 12,000 kg. Both are listed with a single wheelhead.
04
The machine measures 3,400 x 2,800 x 2,200 mm (W x D x H) without peripherals and weighs 12,000 kg. Coolant supply, filtration and any loading system stand outside that footprint, so the installed cell will be larger than the listed dimensions.
