Specially designed for producing cutters of any convex profile, both symmetrical
and asymmetrical, with any size tip radius down to as low as 0,05 mm. with
accuracy better than 0,003 mm., perfect continuity along all cutter profiles
and with lapped surfaces giving roughness in the range of 0,02 Ra.The grinding
wheels are mounted on a special hub which has a centring boss with a wide
front face and polar reference pin. This ensures repeatability and run-out
of the grinding plane within 0,002 mm. and allows bi-rotation of the spindle
which especially advantageous when finishing very small tips. A fast locking
system of the wheel spindle, without the use of spanners, give quick change
over.
Compact, vibration
free structure ergonomically designed for ease of operation. The grinding wheels
are mounted on a special hub which has a centering boss wiyh a wide face
and polar reference pin. The main axis,
croos and swivel movement of the spindle assembly are on preloaded rollers. The sliders are
manually blocked by clamping steel strips so that no pressure is exerted
on the slideways Movement of the
lower cross slide is by a 70 mm dia micrometer dial through a hardened and
grownd screw The reading dial
of the upper cross slide is exactly zeroed on the axis of the longitudinal
slide. The tool spindle
is mounted on high precision oblique bearings and has two 0° -180°
fix stop points, with others every 30°, all excludable.
