Cutting machine

A cutting machine, comprising:

• a machine body including a disc-shaped cutting tool;
• and
• an illuminator configured to emit light from a radially outer portion of the cutting tool toward the cutting tool, the illuminator including
• a first light source and a second light source located across a plane including the cutting tool,
• a first lens having (i) a first incidence surface and (ii) a first emission surface through which light is emittable, and
• a second lens (i) having a second incidence surface and (ii) a second emission surface through which light is emittable,
• wherein:
• the first incidence surface is configured to receive light incident from the first light source;
• the first emission surface includes a first outermost portion located farthest and at a first distance from a first center axis;
• the first center axis (i) includes a first light surface center of the first light source and (ii) is perpendicular to the first light source;
• the second incidence surface is configured to receive light incident from the second light source;
• the second emission surface includes a second outermost portion located farthest and at a second distance from a second center axis;
• the second center axis (i) includes a second light source center of the second light source and (ii) is perpendicular to the second light source;
• and
• a distance between the first center axis and the second center axis is shorter than a sum of the first distance and the second distance.
