Machine Comparison
Junker JUMAT 3S vs Junker Lean Selection
Junker Group vs Junker Group · CNC Grinding Machines
Summary
The Junker JUMAT 3S and the Junker Lean Selection are both CNC grinding machines for shaft-type parts. Few comparable figures are published for this pair, so the table has only two rows: grinding wheel diameter and floor space.
The wheel diameters overlap. The Junker JUMAT 3S is listed with 400/500 mm wheels and the Junker Lean Selection with 400 / 350 mm. The footprints are similar too: 3250 x 2250 x 2200 mm for the Junker JUMAT 3S without peripherals, and 3,340 x 2,660 x 2,325 mm for the Junker Lean Selection without its coolant plant. The two footprints are stated on different bases, so treat the gap as approximate.
Specifications Comparison
| Specification | Junker JUMAT 3S | Junker Lean Selection |
|---|---|---|
| Max Grinding Wheel Diameter | 400/500 mm | 400 / 350 mm |
| Floor Space | 3250 x 2250 x 2200 mm (WxDxH, without peripherals) | 3,340 x 2,660 x 2,325 mm (L x W x H, without coolant plant) |
Advantages
Junker JUMAT 3S
- Suits longer and heavier shaft-type parts
- Listed footprint of 3250 x 2250 x 2200 mm without peripherals, against 3,340 x 2,660 x 2,325 mm without coolant plant
Junker Lean Selection
- Suits small, light shaft-type parts ground at high speed
- Suited to parts with diameters, shoulders and tapers, reached through its B axis
Verdict
With only two comparable rows, the table cannot settle this choice; the work does. The Junker JUMAT 3S suits longer, heavier shaft-type parts and shops short on floor space, with a listed footprint of 3250 x 2250 x 2200 mm. The Junker Lean Selection suits small, light parts ground at high speed, including shoulders and tapers. Compare part length, part weight and wheel speed on each machine's own page before deciding.
