Planer Driving and Feed Mechanism

Planer Driving and Feed Mechanism

Planer Driving and Feed Mechanism - A planer driving mechanism provides the longitudinal to and fro motion of the planer worktable. The following methods are employed for the said purpose.

(a) Open and cross belt drive.
(b) Reversible motor drive.
(c) Hydraulic drive.

A planer feed mechanism provides down feed and crossfeed to the planer tool. The downfeed is applied when machining an angular or vertical surface and crossfeed is applied when machining horizontal surface. The feed is provided intermittently and at the end of the return stroke as in a shaper.

The feed may be given by hand or by power. The methods employed for power feed are:

(i) Friction disc mechanism
(ii) Electrical drive
(iii) Hydraulic drive.
(A) Driving mechanisms

The worktable of the planer can be driven by one of the three methods.

(i) Rack and spur gears
(ii) Spiral rack and worm
(iii) Crank.
