G Series Mechanical Shear

QUICK AND EASY SET-UP

Machine controls are conveniently grouped together at the shear front for easy operation.  The power operated backgage with direct reading, counter type dial indicator, graduated in fractions, enables accurate set-ups to be made quickly. Convenient hand slots in the table and highly visible work area permit rapid material positioning.  Dovetail slots enable optional disappearing stops to be rapidly positioned for frontgaging.

ACCURATE PARTS PRODUCTION

Precision lead screws are mounted in heavy duty steel frames to maintain precise backgage alignment.  Shock absorbing springs further protect position accuracy and compensate for material impact against the gage surface.  The backgage is easily set parallel to the knife by micrometer adjusting nuts at the end of each guide. Fast forward and reverse buttons speed the backgage into approximate position.  Finger tip control of the forward-slow button brings the gage into exact position.  The easy-to-read counter type dial displays backgage settings in inches and 64ths. Fixed, low rake angle ensures accurate part production by reducing the amount of bow, camber and twist introduced into the blank during the shearing process. Knife adjustment on 12" centers ensures that the proper profile can be given to the knife to compensate for variations in knife thickness due to grinding tolerances. Tight knife clearances and an exclusive CINCINNATI precision guided, 2° inclined ram stroke produce superior blank edge conditions.  Spring counterbalances prevent ram float and constrain ram slides against hardened and ground guides during downward and return stroke. High pressure, hydraulic holddowns clamp work piece securely to prevent slippage regardless of variations in thickness.  This adds to the micrometer accuracy of CINCINNATI shears.

RELIABILITY

All frame members are heavy steel plate and interlocked together without welded joints into a non-stressed structure.  Hand scraped, self-aligning bearing shoes and hand scraped bronze slides help guarantee long life and accuracy. Automatic pressure lubrication system supplies oil to important bearing surfaces and rotating parts to extend machine up time and eliminate need for operator oiling.  Automatic lubrication of the backgage screws insures low maintenance and increased wear characteristics. The hardened steel, single revolution jaw clutch rides on hardened steel surface eliminating the need for maintenance required on systems using friction type materials.  This proven design ensures dependable service at low maintenance cost. Maintaining part accuracy over the life of the shear depends on the reliability of the backgage.  Placement of the cross shaft near the ram prevents damage from lift trucks and crane hooks at the rear of the shear.  Automatic backlash compensation in the backgage prohibits gage "float", minimizing maintenance while maintaining accuracy.

SAFETY

This shear is designed to meet the construction requirements of ANSI B11.4 and OSHA as evidenced by a compliance tag affixed to every new machine.  Safeguarding covers all moving parts and areas of potential hazard.  Glare resistant knife and holddown guards offer good vision of the work area while providing optimal safeguarding. Keylock selector switches prevent unauthorized use and protect workers. Manuals on machine set-up, operation and maintenance provide operators with details to safely operate and properly maintain the equipment. The control is designed as standard to operate in an ambient air temperature range of 32° F to 104°.  For ambient air temperatures outside of these ranges, please consult with Cincinnati Incorporated.
