milling machines

A milling machine is a multi axis machine tool used for precision removal of material from flat surfaces, slots, and complex metal profiles. Main motor power typically ranges from 2 to 22 kilowatts with output torque up to 150 newton meters. Spindle speed varies between 60 and 10000 rpm and is controlled by inverter or servo systems. Axis travels for X, Y, and Z are defined between 400 to 1600, 200 to 800, and 300 to 700 millimeters respectively. Positioning accuracy in CNC models reaches ±0.008 millimeter with repeatability of ±0.005 millimeter. Maximum table load capacity ranges from 250 to 1500 kilograms.

The machine structure is manufactured from ductile cast iron with stress relief treatment and hardness above 180 Brinell. Linear guideways of class H with clearance below 0.01 millimeter and ball screws with 5 or 10 millimeter pitch are applied. Coolant systems provide flow rates between 20 and 60 liters per minute for thermal control. The spindle taper is commonly BT40 or ISO50 with radial runout below 0.004 millimeter. Automatic tool changer capacity ranges from 16 to 40 tools. Quality control includes geometric inspection, backlash testing, and surface roughness measurement down to 0.8 micrometers Ra.
