Maalmachines

Maalmachines, or milling machines, are machine tools that remove material from a workpiece using rotating cutting tools. The workpiece is secured on a movable table while the cutter advances to shape flats, slots, holes, and contours. The term is used in Dutch and English technical contexts.

Common configurations include vertical mills with a vertical spindle, horizontal mills with a horizontal spindle, and CNC mills that follow programmed toolpaths. Modern systems may offer 3-axis movement, with 4- or 5-axis options for complex geometry and multi-sided features.

Core components are the spindle, table, and guideways, driven by motors and controlled by manual levers or CNC software. Cutting tools include end mills and face mills. Typical operations are facing, pocketing, contouring, slotting, drilling, and boring, often aided by a coolant system.

Milling machines originated in the early 19th century, with early designs attributed to Eli Whitney. They evolved from manual to computer-controlled systems in the late 20th century. They are widely used in automotive, aerospace, mold making, tooling, and general fabrication to produce precise components.

Key safety considerations include guarding and personal protective equipment. Regular maintenance covers lubrication of guideways, alignment checks, tool calibration, and coolant management to maintain accuracy and prolong the life of the machine.
