The Sertes 75 llydraullc Cuttlng Press ls a fast stroklng, 2 pillar
press whlch ls hydraullcally operated and electrlcally controlled.
The press base ls a folded steel fabrlcatlon whlch supports the bed
fabrlcatlon and lncorporates the hydraullc oll t,ank.
The cutting power ls provlded by two cyllnders whlch are lntegral wlth
the head gulde ptllars whlch sI1de ln bearlngs through the bed. Ttre
flxed piston rods are elanped in a crosg head whlch is bolted Eo the
bed fabricatlon lrlth the press head connected to the tops of the
plllars by trunnlon pl.ns and eccentrlc bushes.
The hydraullc oll pressure ls provlded by a punp drlven by a 5.5 kw
(7.5 HP) electrlc motor coupled to a flywheel. lThe notor prnp unlt ls
uounted directly on t,op of the o1l tank underneaih the bed of thA
Pregs. t
An autooatlc balanclng neehanism enaures that the head renains
parallel to the bed throughout the cutting atrd return strokea, the
upper and lower llntt posltlons being monltored by a lLnear
potentlometer connected across the balancLng valve.
The head llnlt positlons are set by two rotary potentl.ometers on the
control box.
The electrlc control box ls nounted on the rtght hand side guard and
Lncorporates all the controls whlch are connected to the press by
flexlble conduits whlch ternlnate ln two nultlpln plugs and sockets
