Mill drills are an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine's table for flexibility and efficiency. A locking collet prevents the cutting tool from falling away from the spindle when lateral forces are experienced against the bit. Belt Drive Series Mill/Drill.
In a belt drive system, a ratio is used to determine the speed relation between two vbelt pulleys. The speed ratio would be stable if slippage did not occur;
Aug 09, 2010· There is friction here too, expressed as the efficiency of the leadscrew. This is typically 80% for ballscrews and as low as 30% for trapezoidal screws (bronze or delrin nuts on steel) and inertia, as the screw itself has inertia which is dependent on its mass and its length. Now we have all the elements we need.
The first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction .

The vee belt is 'jumped' across the different diameter 'vee groove' to change the final drive rpm. A large diameter, driving a small diameter will increase the speed of the final drive rpm. Inversely, a small diameter driving a large diameter will reduce the final drive rpm.
The basic mill is a Harbor Freight Mini Mill Item number 44991 also called an X2. This was the natural choice for me. This low cost mill has a vast user group with many CNC conversion examples. I knew the upgrade to ball screws was a must but given the CNC Fusion kit is more expensive than the mill itself, I decided to see if I could find a used kit.
For belt drives, an initial tension is applied to give sufficient constant operating tension on the belt and pulley. Taking this tension into account, the radial loads acting on the pulley are expressed by formula (). For chain drives, the same formula can also be used if vibrations and shock loads are taken into consideration. Kr＝fb・Kt.（）
