How much does the KAPP NILES KNG 12 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 KNG 12 is a gear grinding machine for workpieces up to 1,250 mm in tip diameter and 1,545 mm long, which KAPP NILES places among its profile grinding machines. The module range runs from 0.5 - 35 mm, so one machine is specified for fine-pitch teeth and for the coarse teeth found on gears more than a metre across.
Two rows say more about the work envelope than the diameter does. Maximum tooth width is 1,000 mm, four-fifths of the largest tip diameter, so drum-like gears with very wide faces are in range. The 1,545 mm workpiece length leaves room for gear shafts and parts with long journals, not just rings and discs.
The grinding head swivel range is listed as -45 / +120 degrees. That is far wider on one side than the ±45 degrees given for the KX 300 P, and a buyer with helical work near either end should ask KAPP NILES how the two limits apply to the hand and helix angle of the gear in question.
The published table stops there. It gives no workpiece weight, wheel size, spindle power or control, and at this size the weight limit matters as much as the diameter, so it belongs at the top of the list of questions for a quotation.

Strengths & Limitations
Strengths
- Module range of 0.5 - 35 mm puts fine-pitch and very coarse teeth on one machine
- Takes gears up to 1,250 mm in tip diameter with a tooth width up to 1,000 mm
- A 1,545 mm maximum workpiece length leaves room for gear shafts as well as rings and discs
- Grinding head swivel range of -45 / +120 degrees
Limitations
- The published table gives no workpiece weight, which has to be confirmed before heavy gears are planned on the machine
- No control, wheel size or spindle power row is published for the KNG 12
- Gears above 1,250 mm tip diameter or 35 mm module are outside the listed range

Frequently Asked Questions
01
KAPP NILES lists a maximum tip diameter of 1,250 mm, a maximum workpiece length of 1,545 mm and a maximum tooth width of 1,000 mm. The module range is 0.5 - 35 mm. A gear has to fit all four limits, so a wide gear on a long shaft should be checked against the length row as well as the tooth width.
02
The swivel range is listed as -45 / +120 degrees. The two limits are not symmetrical, so for a helical gear close to either one it is worth confirming with KAPP NILES which direction of swivel the gear's hand of helix will use.
03
It covers the gear envelope only: tip diameter, workpiece length, module, tooth width and head swivel. Workpiece weight, grinding wheel dimensions, spindle power, the control and the machine's own weight and footprint are not in it and need to be requested from KAPP NILES.
