(i)Knee and Column type
(a)horizontal
(b)vertical
(c)universal
(d)turret type
(ii)Production (Bed) type
(a)simplex
(b)duplex
(c)triplex
These machines are generally meant for regular production involving large batch sizes. The flexibility is relatively less in these machines which is suitable for productivity enhancement.
(iii)Plano millers
These machines are used only for very large workpieces involving tables in meters.
(iv)Special type
(a)Rotary table
(b)Drum type
(c)Copy milling (Die sinking machines)
(d)Key way milling machines
(e)Spline shaft milling machines
These machines provide special facilities to suit specific applications that are not catered to by the other classes of milling machines.
