2) Expand milling. Grind the selected keyway milling cutter until its outer diameter is reduced by 0.3-0.5 mm (keep a good cylindricity), when milling, leave 0.5 mm allowance at both ends of the keyway, move the cutter back and forth for milling, and then measure the groove width to determine the width allowance.

Milling Cutters and Tools – an Overview. CNC machining is a highly utilised subtractive manufacturing technology. Computer numerical control systems offer less need for manpower and higher levels of automation. One of these automated fabrication methods is CNC milling. It is a process where rotary cutters remove material, which makes it the ...

The present invention provides a milling machine drive mechanism. The milling machine drive mechanism includes a main shaft, a gear assembly, and a machine shaft. The gear assembly includes a first gear and a second gear. The first gear is pin-jointed to the main shaft, so as to rotate with the main shaft. The second gear is operatively connected to the first gear.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.
