The shearing unit is fitted with a simple robust hold-down which is adjustable to any thickness
of material within the cutting capacity of the machine. A shear feed table with adjustable
guides is fitted to allow the accurate feeding of materials. The guide can be adjusted to allow
mitre cutting up to 45 degrees for flat bars or to trim the flanges of angle sections previously
cut at the angle cutting station.
The standard shear blades as fitted permit the bottom blade to be turned four times giving new
cutting edges, whilst the top blade must be ground to sharpen the cutting edge. These blades
give minimum distortion from full capacity down to as light as
1/10
’’ thickness.
Parallel top blades can be supplied (Pt. No.3309) to order for cutting narrow bar widths or
where flatness of cut is not so important.
When the shear blades require sharpening, grind only on the cutting faces - max. regrinding
3/100
’’, after grinding the blades must be adjusted to a clearance of
4/1000
’’. Adjusting screws
have been provided to reset the shear blades, the adjusting screws are positioned around blade
fixing screws, accessable when shear table has been removed. Even clearance between top and
bottom blades is important along the entire blade length and care should be taken to ensure
that the bottom blade is in a vertical plane, parallel to top blade.
WHEN ORDERING SPARE BLADES, ALWAYS QUOTE -
MODEL, TYPE AND SERIAL NUMBER OF MACHINE.

1.
The quality of the cut is an immediate indication of the condition of the blades.
2.
Ensure hold-down is always set for relevant thickness of material being sheared.
DO NOT allow ends of bars to be fed beyond the hold down, because bar
would tend to twist between blades and cause body distortion.
3.
Always feed material between blades from the hold down side.
4.
Keep the blade area clean. Do not allow ‘build up’ of mill scale.
5.
Stay within the rated capacity of the machine.
