Sedgwick PT/MB/CP

Description

All three models of planer thicknesser are designed and built for precision, long life and minimum maintenance. Their rigid mainframe assemblies (made up of cast iron base, side frames, and fixed outfeed table) give exceptional stability, and accurately house the feed and cutterblock bearings, and the infeed and thicknessing tables.

The cutterblock
A large diameter three knife cutter block (2knife on the model PT) provides improved finish, and runs in ‘sealed for life’ bearings for minimum maintenance. Knife setting is aided by height adjustment screws.
Driving the cutterblock is an industrial motor via two heavy section vee belts which, combined with the centrifugal force of the large diameter block, provides ample power.

Surface planing
The cast infeed table (which on the MB/CP planers have increased length for accurate surfacing) rise and fall in square gibs for long term accuracy, and are 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 90-45 degrees making it suitable for bevel work and chamfering, and is easily returned to 90 degrees via a positive step. Adjustable shaw guards for rebating 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 MB/CPs thicknessing table is fitted with a height adjustable anti-friction roller and extension rollers, all of which run in self-lubricating bushes. Large diameter steel feed rollers (one fluted) are driven by an industrial geared unit, which on three phase machines has two speeds. The feed rollers run in self lubricating bushes and are driven from the geared unit by a heavy duty chain for efficient and constant feeding of demanding production work and difficult stock.

Safety Features
The drive 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.
