Job Class: 7

Operational Organization: Operations

General Definition: Performs miscellaneous labor duties in manufacturing operations, loading, or bullets priming.


Loading Operator

  1. Operates various automatic presses for loading and assembly operation. Start up machinery and slide cases and bullet block into machine's opening (bullet seating operation requires operator to align one assembly to another and to make a timely removal of intermediate plate to allow bullets to seat in cases). Positions latch to retain assembly in correct position and to avoid material damage during machine operation. Depress machine clutch arm to automatically seal, widen case mouth, crimp, assemble bullet to case, and color code projectiles for cartridge identification. Pull latch to release plate assembly prior to either carrying unit to sealer station, inspecting materials quickly for obvious defects, etc. requiring special hand tool and extra effort to dislodge plate assemblies for material inspection. Notify T/S Plate Loading of required machine adjustments according to run of defects to avoid excessive scrap.

  2. Operate powder charging machine to load case plate assemblies with propellant. Switch on powder and repeatedly affixes and removes special charging plate for each loading of cases. Slides assembly into machine opens and positions machine latch to retain assembly in correct position during machine operation and to avoid material damage. Activate machinery mechanism to load cases with powder, to recharge loading mechanism for following plate assemblies and to eject assemblies from machine. Notify T/S Loading of required machine adjustments according to quantity of uncharged cases.

  3. Make use of powder detect continuously to check adequacy of powder level in charged case assemblies. Slide assembly into device and lower powder detect pins into charged cases to determine powder level. Empty power from charged assembly when undesired amount of cases remain insufficiently filled and repeat charging procedure. Depress foot pedal to release assembly from press for following operation. Layout of work area may require powder detect station to be manned by an additional worker.

(Primer carriers follow departmental standard operating and safety procedures regarding the quantity of primers to transfer from storage area to machine line.) Removes lids from primer boxes, removes primer route slip, checks for proper lot number, and replaces lids on boxes. Proceeds with transfer cart to machine line, removes one box of primers from cart, proceeds to unit, presses stop button on numeral control system which deactivates clutch system, pulls safety pin on loading door arm and lowers arm, which deactivates micro-switch interlocked with electrical system. Removes empty primer box from dumping device and places in cart or in box holder, removes lid from full box of primers and inserts box into dumping device. Grasps safety pin on loading door arm and raises arm until safety pin engages and micro-switch activates. Pours primers, as required, by raising or lowering lever outside of barricade which positions box and dump primers into hopper. (In Building #3 priming machines are equipped with a timing device that automatically dumps box of primers at set intervals.) High speed priming machines are not turned off when adding primer boxes to dumping device. Primer Carrier opens door and makes certain interior-door between syntron and dumping device is closed, removes and places empty box in holder or on cart, removes lid from full box of primers, inserts into dumping device, closes door and dumps primers as required by using lever located outside barricade.

  2. Records in log book primer lots that are delivered to area. Makes notation in log of date and time new primer lot is introduced in manufacturing operation and number primer lot in use. Informs Check Inspectors within area when new primer lot is introduced and number of new lot.

  3. Collects rejected or scrap primers in assigned area by lifting and carrying buckets of desensitizing solution and primers to common container within area and dumping. Lifts common container within area and carries to scrap pick up point. Mixes desensitizing solution by pouring prescribed amounts of water and desensitizing chemical together as established by Engineering or Production supervision. Adds small amounts of desensitizing solution to scrap buckets when necessary.

  4. Walking and standing required continually throughout shift in order to effectively check various priming machines to assure adequate supply of primers in hoppers to avoid loss of production time. Climb up and down stair step platform, frequently, in area where required, when filling primer hoppers.

Production Inspector

Bullet Inspection

  1. Collects powder charges by taking uncharged cores, bullets or dies to the toolsetter for processing through individual stations to collect various types of powder samples from each powder insert point on machine. Receive samples of powder from toolsetter and proceeds to scale within an area. Dump contents of test components or die onto tray and replace scale. Add standard weights to balance tray and/or position dial or weight of vernier, which indicated fractional parts of subdivisions of main scale, in graduated increments until pointer is centered between markings. Obtain proper reading of weight (usually grain) of powder by totaling weight amounts added to scale, including standard weights and any graduated amounts required to center pointer. Record test results on Depth and Weight of Charge sheet noting date, machine number, time sample taken, weight of sample, shift, etc. Notify toolsetter of high or low charges at particular station so adjustments can be made to correct for the amount of powder placed in the bullet.

Discard sample powder in desensitizing solution after weighing. (Bullet Inspectors in Building #3 are required to discard spotter tracer charging powder in mixture of blue crystals and water. Avoid mixing spotter tracer powder with other types of charging powder due to potentially harmful chemical reaction that may occur.

  4. Retrieve charged cores (Building #3) discarded by Tracer Unit Operators and reinspects for obvious visual defects such as scratches, dents, etc. or gages for

high or low charges, discarding unacceptable material and replacing acceptable cores back into the manufacturing operation.

Removes cartridges from ammunition buggies by frequently stooping over to pick up rounds of ammunition from either standing or sitting position. Make a visual inspection adequacy of cannel ring, waterproofing, or primer positioning including inverted or cocked primers and any obvious surface defects which appear questionable and remove for additional inspection by others. Assure proper orientation of cartridge prior to placing rounds on elevated feed track. Operate machine levers, in correct sequence, repeatedly to mechanically eject profile detect from machine chamber dies.

  2. Make a detail visual inspection of cartridges from gage and weigh inspection machine.
