Note:
MICROMOT steel collets are hardened and thus have a high, consistent flexibility.
They also maintain prolonged accuracy, even after regular use (not to be compared
with unhardened, 4-slit collets and those made of brass or aluminium). The triple slit
collet, which is much more difficult to produce than the 4-slit type, offers a much
better load-bearing surface. This is especially important for the centrical clamping
of cutters with small shaft diameters.
The new MICROMOT 230/E
With a diameter of 37mm and just 270g it oers
convenient handling second to none in its class.
For drilling, milling, grinding, polishing, brushing, cutting and engraving. The extremely slim housing of glass-bre reinforced
POLYAMIDE with a soft component grip area enables the unit to be handled with two ngers (pen grip).
Balanced, low noise special DC motor with high life expectancy. The maximum speed of 21,500rpm can be continuously reduced to 6,500rpm
through full-wave electronics. Oering nearly the same torque also in the lower speed range. This is especially important for micro drilling,
brushing and polishing. Ground, ball-bearing spindle. High quality MICROMOT steel collets: Even the smallest shafts are accurately clamped. No
rattling or vibrating of bits and cutters.
Spindle for tool exchange can be locked at the push of a button. 20mm collar for use in MICROMOT drill stands
and horizontal stands. Includes MICROMOT steel collets (1 each of 1.0 – 1.5 – 2.0 – 2.4 - 3.0 and 3.2mm).
Technical data:
220 – 240 V. 50Hz. 80W. 6,500 – 21,500rpm. Weight 270g. Class 2 insulation.
