Product description

The Norlok Heavy Duty Surelok is the first pneumatically powered heavy-duty clinching machine — with no hydraulics. Built on the Surelok III platform by Norlok Technology Inc. of Brantford, Ontario, it forms a Clinchlok joint — the upper tooling squeezes two plies of sheet metal between a punch and die, locking them together with no rivets, bolts, fasteners, heat or adhesives, no fumes, and little or no damage to painted or galvanized finishes.

Its optimized 3-inch steel C-frame, 24V high-speed smart controls, digital tooling adjustment and single foot pedal make heavy-gauge clinching simple: a 25-inch throat, a 2-1/2-inch stroke and a 40–45 cycle-per-minute rate at 100% duty cycle, running on standard 110V power and ordinary shop air. It is quieter and uses less air than hydraulic alternatives.
