How much does the Junker Numerika 10 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from Junker Group. Configuration moves it a long way.
Overview
The Junker Numerika 10 is listed as a CNC grinder for form and profile work, covering cylindrical and non-cylindrical profiles, with a maximum grinding wheel diameter of 400 mm (15.7 in). The model does not appear on Junker Group's current product pages and the listed figures could not be checked against a maker document, so the table is best read as a description to verify and not as a specification.
Much of that table is descriptive. Workpiece length is given as application-dependent, typically in a 200-600 mm workpiece range, and profile accuracy as single-digit micron form accuracy with no number attached. A buyer therefore has no firm envelope or tolerance to plan against, and should ask for both in writing for the specific machine.
The grinding side is clearer. A high-frequency motorized spindle drives the wheel at up to 80 m/s in the conventional setup, and a CBN configuration is noted as available without a speed of its own. Dressing is programmable, by CNC diamond roll dresser or point diamond. Profiles can be brought in as CAD data, and the control row names Junker Numerika software. The bed is reinforced polymer concrete, the guideways are hardened and precision-ground, and coolant is a high-pressure flood system.

Frequently Asked Questions
01
Form and profile grinding, on cylindrical and non-cylindrical profiles. The table lists CAD profile data import and Junker Numerika software, with a programmable CNC diamond roll dresser or point diamond for the wheel.
02
The table does not give a fixed limit. Workpiece length is described as application-dependent, typically in a 200-600 mm workpiece range. No center height or workpiece weight is listed, so the real envelope has to be confirmed for the individual machine.
03
A maximum grinding wheel diameter of 400 mm (15.7 in) and a wheel speed of up to 80 m/s with conventional wheels, on a high-frequency motorized spindle. A CBN configuration is listed as available, but the table gives no wheel speed for it.
04
Only as a guide. The model is not on Junker Group's current product pages and the table could not be checked against a maker document. Several rows carry no number at all, including profile accuracy, so ask for measured results from the machine being considered.
