Point of Operation Guarding
The machine must not be operated without point of operation guarding. It is the responsibility of the user to insure the machine is operated safely and has appropriate guards for the type of work being performed. The manufacturer can not satisfy the guarding requirements for the many and varied applications these machines can perform. The manufacturer will assist the purchaser with his selection of guarding and will offer factory installation of the guarding selected by the purchaser.

Hydraulic System

The entire hydraulic system is to JIC standards and makes maximum use of flared fitting and "O" Ring seal connectors. All valves are flange mounted or cartridge type components to simplify servicing.

The motors and pumps are direct coupled by a bell housing to reduce noise and insure perfect alignment.

Machine Features

Control Panel
The control panel features a lockable mode selector to provide "Off", "Inching" and "Single Cycle" functions. In the Off position the machine is completely inactive. The Inching mode allows the operator to gradually move the top beam down to check the work prior to taking the cut or to facilitate checking knife clearance when this may become necessary. This function can also be used to maintain hold down pressure after taking a cut to allow the operator to support the material on the table and prevent it from falling after the hold downs have released.

Knife Clearance Adjustment

• Push buttons control a motorized knife clearance adjustment for instantaneous clearance changes.
• The position indicator shows from minimum to maximum in inch and metric plate thickness.
• Following knife regrinds the indicator can be easily calibrated to show the appropriate new positions.

Stroke Length Adjustment
By means of a simple thumb screw the stroke length may be adjusted to reduce cycle time and increase productivity on shorter work by as much as an additional 250%.

CNC Back Gauge System

The machines are equipped with a 48" range CNC back gauge.

Fully sealed pre-lubricated gear boxes are driven from the self locking reduction box. On both output shafts of this gearbox are two indexing couplings which provide a simple and convenient means of adjustment to compensate for any back gauge misalignment. The gear drive finally rotates two rolled acme screws which position the gauge bar.

CNC Rake Angle Control
Changes in the rake angle can readily be made to enable the shear to cut metal thicker than the rated capacity or to speed productivity by shearing thinner metal at low rake angles, requiring less stroke, resulting in faster cycle time.

To make a change in rake angle, pull out the lock pin and rotate the selector to align the arrow with the appropriate metal thickness up to the machine's maximum capacity, then release the lock pin. The new rake angle will immediately be adopted.
