Inspection of Milling Machines

Milling machines have a cutting tool with multiple cutting blades rotating around its own axis. This cutting tool moves linearly and removes chips from the workpiece underneath. The cutting tool that makes a rotary movement on a milling machine is called a milling knife. In lathes, this rotational movement makes the workpiece unlike milling machines.

Comparing lathes and milling machines results in the following results:

  • While turning the workpiece in lathe workbench, milling machine makes this movement cutting tool.
  • While lathe lathe makes linear movement cutting tool, milling machine makes this movement workpiece.
  • In lathes, workpieces have cylindrical cross-section and in milling machines workpieces are prismatic.
  • Single-ended cutting tools are used in lathes, while multi-cutting cutting tools are used in milling machines.

In milling machines, the body is the main part of the machine as in lathes. All other elements are connected to the body. The bodies of milling machines are made of cast iron and are vibration-absorbing. In the interior of the body, the drive motor, the drive transmission elements, the speed box and other auxiliary parts are arranged.

Milling machines are among the machines that pose a danger to employee health. In accordance with the Regulation on Health and Safety in the Use of Work Equipment, inspections of milling machines and components must be carried out under conditions deemed appropriate by the manufacturer, unless otherwise stipulated in the relevant standards. However, if the manufacturer does not foresee any period or condition, then a risk assessment is carried out based on operating conditions, frequency of use and how much of the machine is used and control periods are determined accordingly. However, it must be checked at least once a year.

Inspection of milling machines, in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations. These standards are based on a few standards:

  • TS EN 13128 + A2 Safety on machine tools - Milling machines (including boring machines)
  • TS ISO 240 Milling cutters - Connection of blades - Dimensions
  • TS EN ISO 15641 Milling cutters for high-speed machining - Safety regulations
  • TS EN 847-1 Cutting tools for woodworking - Safety regulations - Part 1: Milling tools, circular saw blades
