3.6.8 Grinding
Groove cutterhead, tongue cutterhead:
The cutters are ground on a suitable Weinig grinder for
tools with the grinding support 931 073 006 and grinding
template 507 300 01. The grinding template can be
used for the groove and tongue cutterhead set for
groove widths from 3.5 to 6.5 mm. The groove width
must be 0.1 to 0.5 mm larger than the thickness of the
tongue. The grooving saw must be removed to grind the
cutters of the groove cutterhead. Spacer rings must be
fitted in accordance with the groove width.
The grooving saw can be ground on the back of the
teeth without being removed from the tool. A diamond
grinding wheel must be used for this purpose. The back-
clearance angle is set to between 15° and 18°.
The cutters of the tongue cutterhead are ground while
fitted in the tool.
The tongue cutterhead can be set to a tongue thickness
of 3.5, 4.5 or 6.5 mm with the aid of the spacer rings
supplied. The spacer rings are used as shown in the
table below for regrinding and adjusting to the tongue
thickness.
Each set comprises: 2 x 5 mm thick spacer rings, as well
as one each in thicknesses of 4.7, 4.4, 1 and 2 mm.
