Planer Milling Machines

Planer type mills are the largest milling machines. Their general appearance and construction are those of a large planer but the difference is that milling is performed instead of planing. One or more milling heads are substituted for the single-point cutting tools used on planers, and the motion of the work past the tool is a feed rate motion rather than a cutting speed motion. The worktable and bed of the machine are heavy and relatively low to the ground, and the milling heads are supported by a bridge structure that spans across the table. These heavy duty milling machines, called Plano-miller, look like planing machine where the single point tools are replaced by one or a number of milling heads; generally used for machining a number of longitudinal flat surfaces simultaneously, viz., lathe beds, table and bed of planning machine etc. Planer machines are similar to bed type machines but are equipped with several cutters and heads to mill various surfaces.

Milling Machine and Planer

It is often desired that the operations of milling and planing can be combined together so that one machine capable of performing both the operations can be used which saves a lot of factory space, money and time. Thus, milling attachments were made for the planer in a single machine, and attached to the cross-rail. The changes required from the planer drive, are an extra belt to rotate the cutter, and a special countershaft to slow down the move merit of the table. This attachment can carry a slabbing, gang, or formed cutter on an arbour for horizontal milling; or it can carry end mills, by turning the attached head through 90 degrees, thus bringing the spindle to a vertical position. This last arrangement of the spindle is of great utility, as it allows cutters to reach down into places which would be inaccessible by any other means.

Planer Milling Machines and its Applications

Some of the industrial applications where planer type milling machines play an important role are:

• It is widely used in industries for precise shaping of metals & various solid materials.
• These machines are ideal for various processes such as slot cutting, routing, welding & turning in metallurgical industries.
• The machine is intended for milling of housing and basic components made of ferrous and non-ferrous metals and of some selected plastics.

Buying Planer Type Milling Machines

From the viewpoint of saving time and effort it is often desirable to combine milling and planing operations in a single machine. Thus, milling attachments are produced for a planer and the end result is what we refer to as a planer type milling machine. This is a highly specialized item of equipment that can prove to be quite costly when bought new. Such expenditure is not always possible for individuals or small businesses, especially those looking to expand. A more financially viable alternative is to look for a planer type milling machine for sale at a used industrial machinery auction site online.
