CNC工作機械のデータシートの主要な仕様(ストローク、スピンドル、精度、制御システムなど)を解読して、自信を持って機械を比較できるようにします。

CNC machine datasheets are packed with specifications that can be confusing for first-time buyers. Here is a plain-language guide to the terms that matter most.

Travel (X / Y / Z)

Travel describes how far the machine axes can move. It determines the maximum workpiece size the machine can handle.

Spindle speed and taper

Spindle speed (RPM) affects cutting speed and surface finish. The spindle taper (such as BT40 or BT50) determines which tool holders the machine accepts.

Positioning accuracy

Positioning accuracy, usually given in millimeters, describes how precisely the machine can position the tool. Tighter accuracy means better repeatability for precision parts.

Control system

The control system (such as Siemens, Fanuc or Syntec) is the machine's brain. Choose a control your operators already know to reduce training time.ime.
