How much does the KAPP NILES KX 500 Flex Gear Grinding Machine cost?
Estimated price range
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 Flex is the 500 mm size in KAPP NILES's generating and profile grinding range: maximum tip diameter 500 mm, workpiece length 1,000 mm and face width 520 mm. Module range is 0.5 - 8 mm in generating grinding and 0.5 - 12 mm in profile grinding, and the grinding head swivels ±45 degrees.
Set beside the KX 300 P, which lists 350 mm of tip diameter, 320 mm of face width and 0.5 - 8 / 0.5 - 10 mm modules, the larger machine adds diameter, face width and coarser profile grinding. It does not add coarser generating grinding, where 8 mm is the ceiling on both. A shop whose heavier gears are above 8 mm module should plan them as profile-ground work on either size.
The face width deserves a second look. At 520 mm it is slightly more than the tip diameter limit, and with 1,000 mm of workpiece length the machine takes long shafts and wide gears as readily as large discs.
The table for this model has no weight, footprint or spindle rows. A dealer datasheet for a 2009 KX 500 gives a machine weight of approx. 11,200 kg (24,692 lb). That describes a machine of that year, so use it as an indication of size class and ask for the present figure.

Strengths & Limitations
Strengths
- 500 mm tip diameter with 1,000 mm of workpiece length
- Face width of 520 mm, against 320 mm on the KX 300 P
- Profile grinding to 12 mm module and generating grinding to 8 mm on the same machine
- Grinding head swivels ±45 degrees
Limitations
- Generating grinding stops at 8 mm module, the same ceiling as the smaller KX 300 P
- Gears above 12 mm module are outside the listed range for either process
- No weight, footprint, spindle or control rows are published in the table

Frequently Asked Questions
01
Tip diameter goes from 350 mm on the KX 300 P to 500 mm, face width from 320 mm to 520 mm, and the profile grinding range from 0.5 - 10 mm to 0.5 - 12 mm. The generating grinding range is 0.5 - 8 mm on both machines and the head swivel is ±45 degrees on both.
02
No. The generating range is 0.5 - 8 mm. A gear coarser than 8 mm module falls inside the 0.5 - 12 mm profile grinding range, so it can be ground on the machine, but as a profile-ground part.
03
KAPP NILES's table for the model does not give a weight. A dealer datasheet for a 2009 KX 500 lists approx. 11,200 kg (24,692 lb). Treat that as a guide to the class of machine and get the weight of the build on offer before planning the foundation or the lift.
