Our best estimate for a cnc gear cutting machine in this class — not a quote from KAPP NILES. Configuration moves it a long way.
Overview
The KAPP NILES KX 500 documented here is a KX 500 FLEX gear grinding center for generating and profile grinding, as described on a dealer datasheet for a 2009 machine. It has a nominal workpiece diameter of 500 mm (19.7 in) and takes parts up to 1,000 mm (39.4 in) long. A machine under the plain KX 500 name is not in KAPP NILES's current lineup, so these figures describe that 2009 build and are most useful to someone assessing a second-hand machine.
The two processes have different module ranges: 1.0 – 8 mm for generating grinding and 0.5 – 12 mm for profile grinding. Tooth width along Z is up to 520 mm (20.5 in), radial travel in X is 525 mm (20.7 in) and tangential travel in Y is 250 mm (9.8 in). The grinding spindle swivels ±45° on the A axis, and the datasheet counts 7 simultaneously controlled CNC axes.
The grinding spindle is the B axis. It runs to 7,500 min-1 and carries wheels up to Ø 320 mm with integrated automatic balancing (Dittel). Profile dressing is handled by a GMN TSE 100cg unit on the B3 axis, a single-roll design with a Ø 100 mm dressing wheel rated 1.25 kW (S1) at 6,000 min-1. Rapid traverse is 20,000 mm/min in X and 10,000 mm/min in Y and Z, with the A axis swivelling at 50°/s. A rotary indexing table with a 270° driving range and a maximum swivel speed of 210°/s completes the list.
Installation needs planning. The machine weighs approx. 11,200 kg (24,692 lb), occupies approx. 6.8 x 5.3 x 3.2 m (22.3 x 17.4 x 10.5 ft) and has a connected load of approx. 80 kVA at 400 V, 50 Hz. The control is a Siemens Sinumerik 840D with Simodrive 611D digital drives, not the 840D sl listed for the KX 260, so the support position for a control of that age is worth establishing before a purchase.

Strengths & Limitations
Strengths
- Generating and profile grinding on one machine, with module ranges of 1.0 – 8 mm and 0.5 – 12 mm respectively
- Tooth width up to 520 mm (20.5 in) on workpieces up to 1,000 mm (39.4 in) long
- Grinding spindle to 7,500 min-1 with integrated automatic balancing (Dittel) and wheels up to Ø 320 mm
- Rapid traverse of 20,000 mm/min in X and 10,000 mm/min in Y and Z
- Rotary indexing table with a 270° driving range and 210°/s maximum swivel speed
Limitations
- Not in KAPP NILES's current lineup under this name; the figures describe a 2009 machine on a dealer datasheet
- Generating grinding starts at 1.0 mm module, so finer pitches down to 0.5 mm are profile ground only
- The control is a Siemens Sinumerik 840D with Simodrive 611D drives, not the 840D sl listed for the KX 260
- Needs approx. 6.8 x 5.3 x 3.2 m (22.3 x 17.4 x 10.5 ft) of space and a connected load of approx. 80 kVA

Frequently Asked Questions
01
Not under the plain KX 500 name. The figures here are those of a KX 500 FLEX as documented on a dealer datasheet for a 2009 machine. The headline sizes on that datasheet are a 500 mm (19.7 in) nominal workpiece diameter, a 1,000 mm (39.4 in) workpiece length and a 520 mm (20.5 in) tooth width. A later machine may differ in control and equipment, so match the datasheet to the build year.
02
1.0 – 8 mm in generating grinding and 0.5 – 12 mm in profile grinding. Gears finer than 1.0 mm module or coarser than 8 mm are therefore profile-ground jobs on this machine, which affects cycle time more than it affects whether the gear fits.
03
The grinding spindle is the B axis, with a maximum of 7,500 min-1, a maximum grinding wheel of Ø 320 mm and integrated automatic balancing (Dittel). The profile dressing unit is a GMN TSE 100cg on the B3 axis: single-roll design, Ø 100 mm dressing wheel, 1.25 kW (S1) and 6,000 min-1.
04
The datasheet gives a space requirement of approx. 6.8 x 5.3 x 3.2 m (22.3 x 17.4 x 10.5 ft), a machine weight of approx. 11,200 kg (24,692 lb) and a connected load of approx. 80 kVA at 400 V, 50 Hz. A site on a different supply will need that addressed as part of the installation.
05
Feeds and rapid traverse are listed as 20,000 mm/min in X, 10,000 mm/min in Y, 10,000 mm/min in Z and 50°/s on the A axis. X, the radial axis with 525 mm (20.7 in) of travel, is twice as fast as the other two linear axes. The rotary indexing table swivels at up to 210°/s over a 270° driving range.
