Tuning spindle for Proxxon MF70 (with a serial number < = 12001)
It is more stable in design and, thanks to the new ER11 collets, can accommodate tools up to 8.0 mm in diameter.
The collets are available from 1.0 mm in (0.5 mm increments) to 8.0 mm diameter, as well as a 3.175 mm collet.
The spindle is turned in a stainless steel chuck and has a concentricity accuracy of approx. 0.01 mm.
Since the milling motor has a power of only 100 watts, larger tools must be used with care!.
To obtain the full benefit of the tools even in harder materials, you can purchase a matching mini-planetary gear with a reduction ratio of 1:4. This quadruples the torque and reduces the maximum speed to 5,000 rpm. Please note that the planetary gear is not included in the scope of delivery of the spindle!
