M6 - Bench Type Milling Machine

Project No.: M6

Project Title: Bench Type Milling Machine


Despite the continuing evolution of new advanced machine tools, conventional machine tools (such as a milling machine) are still flexible and important equipment in a workshop. It provides not only flexibility for producing job-shop type works, but also the fundamental knowledge and skills required for further study in those AMT equipment. The manufacturing of a bench-type milling machine would thus become meaningful to the trainees studying in the mechanical and manufacturing engineering. It enables them to understand the structure as well as the design and working principles of such a machine.

In general, a vertical milling machine consists of 5 main parts namely: the base, column, knee, machine table, and the headstock. The base and the column are generally made of cast iron or fabricated from steel plates that provide ample support for the whole machine. The headstock is one that transmits rotational motion from the motor through belt drives and gear trains to the spindle and then the cutter. The workpiece is general clamped on a machine vice or directly mounted onto the machine tables which consequently impart linear motion to the workpiece for producing flat surfaces, drilling, boring, or even slot milling.

Different machines are different in designs particularly when the size and accuracy are concerned. It is not expected to have the machine be made as precise as possible. But rather be as simple as possible such that it can be installed on a bench in the workshop or at home for carrying out the above milling operations.


The figures below show the outline of the main features required for the bench-type milling machine.

  1. Motion is transmitted from a motor via a pulley and belt system to the spindle and then the cutter.
  2. The machine table provides the necessary motion to the workpiece for milling operations.
  3. Manual feed is recommended for both slideways.
  4. For simplicity, the knee is omitted.
