Features
Single geared Twin driving gears on main shaft.  Includes shaft extension on        both ends.
     High tensile iron main drive gears and steel pinions, totally enclosed.
 
Two Point Eccentric Crankshaft forged of alloy steel reduces the stamping load deflection and thus, reduces the vibration from snap through shock.
 
Four Piece High Tensile Cast Iron and/ or Steel Frame component materials chosen to reduce overall press vibration level. The open top of crown provides easy access to tie rods that are drilled to accept “Heatrex” heaters to release the tie rod nuts.
 
Bed Deflection designed for specified deflection between tie rod centers with maximum press tonnage distributed over the center two-thirds of the R-L bed area.
 
Combination Hydraulic Clutch and Brake includes dual clutch valves and provides quick starts and fast stopping times for high production progressive die applications.
 
Air Operated Flywheel Brake interlocked with stop circuit eliminates coasting resulting in quicker access to die area.
 
Main Bearing Support Wedges reduce the eccentric shaft deflection from reverse loads encountered in heavy blanking applications.
 
Saddle Bearings in the connection screw are precision machined for a full contact fit with the bottom of the connection to reduce snap through motion.
 
Eight Point Slide Guiding System provides a minimum clearance guide for the slide through its full height at all stroke and adjustment positions.
 
Motorized Shutheight Adjustment with Digital Readout provides quick die set-up and adjustments. 
 
Slide Face Machined with general purpose T-slots F-B on (6.0 in.) centers starting on center.
 
Bolster Plate Machined with general purpose T-slots F-B on (6.0 in.) centers starting on center.
 
Counterbalance System in Uprights statically balances slide and upper die weight. It is not intended to provide a dynamic inertia balance.
 
E2-MonitorFlow® The patented Minster MonitorFlow® System supplies a continuous flow of pressurized and filtered oil to all lubrication surfaces ensuring reliable operation.  It monitors flow and pressure to individual points as well as the oil level and pressure within the entire system.
 
From the manifold on the press crown oil is channeled to the bearings, gibs, gears and counterbalances.  Individual flow switches monitor oil flow to the main and connection bearings from the sump line back to the reservoir.  Monitoring flow and pressure in this manner enables fault detection from both broken and/or plugged lines.  The press is stopped, and a diagnostic message is displayed on the control screen indicating the location of the fault should one occur.  This aids the operator in pinpointing the problem area.
