5 Axis Machining Solution

One of the main features of the Doughty Drive’s unique design is that there is NO backlash. Now incorporates slew bearings with a 28mm hole through the centre, enabling cables, hoses etc. to pass.

With a reduction ratio of 33.333 : 1, it gives great holding torque of 20 ft/lbs – 27 Nm. This ratio gives a very good resolution, 66,666.666 steps per rev, and 185.185 micro steps per deg., with positional repeatablity of + – 30 arc seconds.

The units have a maximum fast travel of 120 degs per second, or 20 RPM. They can be mounted vertically or horizontally, and used like an indexing head or rotary table. With two drives connected together at right angles to each other, they form a B/C axis combination, and a router or spindle can be attached. The weight is just 3.5 Kg. (8lb), B/C drive 9 Kg (20lb)

Two DD100 drives are connected together with a rotary connecting plate and form the B/C drive.
They are both stepper motor driven, nema 24, 300 oz./in, @ 2.8 amps. The stepper motors are an integral part of the drives and are included, servo motors are not an option at this time.

With the use of a 1.5 HP or 2 HP spindle, or similar sized router, the drives are suitable for routing foam, plastic, wood or light aluminium.
