Danobat DANUNI-4100

With Ø4,100 mm (Ø161 in) of swing over the gap, the Danobat DANUNI-4100 is the larger of Danobat's two gap bed grinders for landing gear components. It is the size for the largest gear legs, where the leg, its trunnions and its attachment lugs describe a circle more than four metres across when the part turns.

Unlike its smaller sibling, this model lists a single gap entry: 0-1,450 mm (0-57.1 in). The DANUNI-3050 shows a 500 mm (19.6 in) gap with an adjustable one as an option; here the table prints only the adjustable range and carries no asterisk. The swing over the table is Ø1,600 mm (Ø63 in), so even the section of the part that runs over the full bed has generous clearance. Distance between centers is 3,750 mm (147.6 in).

What does not grow is the grinding end. The wheel is Ø915 mm (Ø36 in), the wheelhead 20 kW (26.8 hp), the peripheral speed 60 m/s (11,811 sfpm), and the weight between centers 1,500 kg (3,307 lb). A buyer should read that literally. The machine is larger to give clearance, not to carry heavier parts or take heavier cuts.

Danobat's description of the DANUNI concentrates on the process around the machine: tooling that keeps an asymmetric part balanced and stops it being mounted wrongly, a touch-screen interface for configuring any undercarriage with its tooling and its grinding and measuring application, and an integrated MDM gauge that measures oversize before the cut and reports roundness, run-out, cylindricity and diameters afterwards. The ergonomic design is said to allow easy part assembly, safe movement on the machine and space for maintenance.
