Light and Medium Section Mill offered by our company, is usually used to machine flat surfaces, but can also produce irregular surfaces. This mill is most commonly found in shops is a vertical spindle machine with a swivelling head. This is very effective and safe to use. This requires very low maintenance and replacement costs. Light and Medium Section Mill differs from a lathe in that the tool head itself rotates at high speed whereas with a lathe the part itself that is being worked on rotates.
