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 Grindor 2 is a CNC cylindrical grinder that works by QUICK-POINT traverse grinding, in which a narrow CBN wheel travels along the part. The listed figures put it at up to 650 mm (25.6 in) between centers, depending on configuration, with a 125 mm (4.9 in) center height and a 50 kg (110 lb) workpiece limit between centers. It is not in Junker Group's current lineup, and the table could not be checked against a maker document.
Wheel speed is listed as 80 – 140 m/s in the QUICK-POINT CBN configuration, and table travel as 700 mm (27.6 in), a little more than the grinding length. The accuracy row states roundness below 0.5 µm and a diameter tolerance of ± 2 µm in production. On an older machine those are values to prove with a test part before a job is quoted on them. The control is described as a Junker CNC with integrated in-process gauging, and machine weight as approx. 6,500 kg (14,300 lb).

Frequently Asked Questions
01
The listed figures give a grinding length of up to 650 mm (25.6 in) between centers, depending on configuration, a center height of 125 mm (4.9 in) and a workpiece weight of 50 kg (110 lb) between centers. Table travel is listed as 700 mm (27.6 in).
02
It is not in Junker Group's current lineup. The table on this page has not been checked against a maker document, so use it as a guide and confirm wheel speed, travel and accuracy on the actual machine before relying on them.
03
QUICK-POINT traverse grinding with a narrow CBN wheel. Wheel speed is listed as 80 – 140 m/s in that configuration. Because the wheel is narrow and traverses the part, steps and diameters come from the CNC path and not from a wheel dressed to the shape of the part.
