Wood working Machines

Wood working Machines

In modern workshops, wood working machines are used instead of hand tools. Machines have following advantages over the hand tools:
1. More production.
2. Less fatigue to workers.
3. Saving in time.
4. More accuracy.

Some of the machines are:

Wood working lathe

A wood working lathe consists of a cast iron bed, a head stock, tail stock, tool rest, live and dead centers and driving mechanisms. It is used for producing round symmetrical jobs. Scrapping tools, chisels and turning gauge are used as turning tool on a wood working lathe.

Circular saw

It is generally used for cross cutting of the wood. Other operations like grooving, rebating, tenoning, chamfering, tapering etc. are performed on this machine. The wood is fed against a rotating cutter.

Thickness planner

The thickness planner is a machine in which wooden planks and boards are planed evenly to a desired thickness. Such planers are manufactured in two varieties i.e. single and double surfaces. A single surface has only one cutter head and cuts from top side only. Thus, a board or plank to be planed has to be fed twice, once to plane its one side and then the other. The double surface carries two cutter heads; one cutting from the top and other from the bottom of the stock, thus finishing both sides in a single operation.

Band saw

It consists of table, guide, pulleys, belt and tension adjusting screw. It is used to saw the wooden pieces length wise. Fence is used to adjust the thickness of cutting strip. A band type cutter revolves over the two pulleys.
