Sedgwick PT

Construction

The Sedgwick PT255 planer thicknesser is designed and built for precision, long life and minimum maintenance. Its rigid mainframe assembly (cast iron base, side frames, and fixed outfeed table) gives exceptional stability, and accurately houses the feed and cutterblock bearings, and the infeed and thicknessing tables.

The Cutterblock

A large diameter three knife TERSA cutterblock provides improved finish, and runs in ‘sealed for life’ bearings for minimum maintenance.

Driving the cutterblock is an industrial motor via a heavy section vee belt which, combined with the centrifugal force of the large diameter block, provides ample power.

Surface Planing

The cast infeed table rises and falls in square gibs for long term accuracy, and is fitted with a rule showing depth of cut. A generously proportioned cast iron fence is then mounted off the table on a cast iron bracket. The fence can be tilted between 90º – 45º making it suitable for bevel work and chamfering, and is easily returned to 90º via a positive stop. Adjustable shaw guards are also supplied.

Thicknessing

For long term accuracy, and to avoid time consuming mode changes, the surfacing tables remain in place when thicknessing, utilising instead a dual function chip collection hood.

The thicknessing table is again cast iron and is mounted on a large diameter precision ground pillar to ensure precise and parallel positioning, with an off-centre lock for added rigidity. The steel feed rollers (one spiral-fluted the other rubber-coated) run in self-lubricating bushes and are driven by a heavy duty chain for efficient and constant feeding of demanding production work and difficult stock.

Safety Features

The drive assembly is totally enclosed by the rear machine guard, removal of which provides easy access to the motor drive assembly for any necessary maintenance. The cutterblock is guarded at the rear by a fixed guard attached to the fence, and at the front by a bridge type guard.
