PART ROTATION is controlled by a belt that is driven by a servo motor. The drive belt motor speed for each cut of the process is automatically calculated based on the inputted surface feet or meter per minute. Normally this is 1,000 feet (30.5 meters) per minute. If speed change is necessary, it can be altered easily through the touch screen .
FEED RATE or feed per revolution of the part is programmed via the touch screen. The unit synchronizes all work through the Digital Signal Processor (DSP).
DEPTH OF CUT can also be programmed via the touch screen. Two or more passes, such as a rough cut and a finish cut, may be required if achieving the required cut depths in one pass is unpractical. Both cuts can be accomplished at a single station by programming cut requirements at setup.
MACHINE BASE - A heavy, normalized steel fabricated provides accurate alignments within the machine. A special cast iron platform is mounted to the top of the base to support the “U” journals and cutting tool feed slides. This provides excellent dampening of any vibration induced by the cutting process.
CONVENIENT SETUP is assured as the cut length zero reference is established by using a single learn button on the touch screen for each tool. The cut diameter is reference using a gauge block or a different learn button for the cross slide servo motor. The result is faster, simpler changeover from part to part.
SIMPLIFIED PNEUMATICALLY CONTROLLED WALKING BEAM SYSTEM for automatic load and unload, replacing the Camco Box used in earlier models. The result is faster operation and simplified troubleshooting and maintenance. By connecting the belt drive head assembly to the walking beam system, both move up and down simultaneously to reduce cycle time.
Stationary armature holders are attached to the journal supports so they are automatically adjusted as the journal supports are adjusted for different parts. This eliminates the need for the cumbersome Acme screw wheel adjustments used on the prior models.
Armature transport via walking beam.
CHIP COLLECTION is designed into the machine bed. Chips fall via gravity down a sloped base into a collection drawer located on the lower right-hand side of the machine. Deflectors mounted above the cutting tools direct the chips toward the sloped base of the machine. This eliminated the need for vacuum chip collection systems. The collection drawer can be removed externally from the machine to dispose of the chips.
The armature BELT DRIVEN HEAD accurately controls the rotation speed of the armature through a servo-controlled motor for the precise setting of the cutting speed. The belt can be run in either direction to provide clockwise or counterclockwise rotation of the armature during cutting.
Easy swivel of the belt-driving head about a radius from the center of the lamination stack provides quick setup for reversing rotation direction of the armature. Neither the head nor the armature needs to be repositioned when the head is swiveled.
Belt tension is set through a sensitive air-tensioning device. The belt provides an adjustable and repeatable pressure on the armature that minimizes deflection of the armature while creating a positive drive by the belt. Setting the lower position of the head with a preset turret stop block sets the belt wrap. A turret stop block also controls the clearance of the belt above the armature when the belt-driving head is in the raised position. This reduced motion shortens cycle time.
