BULLARD MULTIPLE CUTTERS AND REAMERS
This illustration shows a complete set of cutters and reamers for producing a threaded hole. The hook may section of the bar shows the backing and inserted hardened seat for the reamers.
The cutter and thread chasers shown can be used in the square cutter slot of this bar.
Internal cutters and thread chasers cannot be used for external work. External cutters and tools are in Section I, Page 5.
Spiral Bullard Multi-Bar System
The Bullard Multi-Bar, as used in the turrets of Bullard Vertical Turret Lathes, is a multipurpose bar. The operations of chamfering, boring, reaming, and threading are all done with the same bar. The Multi-Bar has a square broached cutter slot provided with an adjustable backing-up screw, as shown in the broken-away portion of the bar illustrated to the left. To generate a hole, a set of three cutters and two reamers is used. The cutters are slipped in and out of the Multi-Bar in sequence: chamfering, rough boring, and true boring. Observation stops on the micrometer dial of the cross-feed screw are used for rapid setting to repeat sizes on succeeding pieces. When true boring has been completed, the main head is set on dead center with the aid of a center stop on the machine, and the reamers are inserted in the rectangular slot of the bar. The sizing reamer is used first to ream the hole to within a few thousandths of its final size, leaving a uniform amount of stock to be removed by the finishing reamer. Since the reamers are free to float in the Multi-Bar, the danger of producing eccentric holes is eliminated. Always stop the machine before withdrawing the reamer from the hole.
It is recommended in a set-up of this kind that a set of reamers be kept undisturbed for each size of hole to be produced. In this way, speed and economy are achieved because valuable set-up time is saved, and the equipment is spared the waste of repeated grindings for various hole diameters. The Multi-Bar also accommodates the Standard Thread Chasers and Bottom Boring Cutter described on Page 9 of this section.
For data on Boring Cutters, see Page 7 of this section.
Boring Bars and Reamer Bars
For tool set-ups permitting the use of separate Boring and Reamer Bars, see data on these Bars on Page 6 of this section. The Boring Bar is the same as the Multi-Bar with the cutter slot only, and the Reamer Bar has only the Reamer slot.
Because Bars may become slightly distorted under severe boring conditions and because Reamers in such Bars will not produce true holes, we are now offering these individual Bars for boring and for reaming.

BULLARD STANDARD REAMERS
Sízíng Reamers for use in Bullard Mu1ti-Bars and Bullard Reamer Bars are desígned for removíng all but the last few thousands of stock from holes whích have been prevíously rough and true bored, leaving a uniform amount of stock for finish. Finishing Reamers then bríng them to final síze and finish.
The bodies of these reamers are made from a good grade of carbon tool steel. The blades are All adjusting screws, binding screws, and nuts are hardened.
The adjustíng screws in the top of the reamer body are used to adjust FIG. the blades to the requíred size and provide backing for them. When the correct settíng has been obtained, plus a few thousands allowed for grindíng, the clampíng screws are tíghtened, and the reamer set up in the grínding fixture and ground as descríbed on Page 11.

BULLARD REAMER GRINDING FIXTURE STANDARD REAMERS
The use of the Bullard Reamer Grinding Fixture facilitates the proper grinding of reamers with the removal of a minimum of material from the blades. Correctly ground reamers save production time and minimize rejections. With this fixture, the angles on one cutting edge are always exactly duplicated on the other, and all reamers will be ground alike.
The Fixture is simple to use. It may be readily clamped with T-Bolts to a plain or universal table of any tool grinder. Keys in the base align the fixture with the table. All settings of the fixture are positive, and changes from one setting to another may be made rapidly. There are no graduations to approximate. Reamer Holders are positively located on the spindle and may be easily interchanged. Two sizes of holders cover the entire range of Bullard Reamers, one taking sizes from 1/8 to 3 1/2 inches, the other from 2 7/8 to 6 inches. This operation can be done by holding the reamer in a standard vise on any tool grinder.
CONSTRUCTION grínder.
The Body is piloted to swivel on the Base. The Headstock Spíndle ís steel, hardened and ground, and ís mounted on two roller bearíngs packed with heavy oil and permanently sealed. Reamer Holders, Index Pin, and Detent are made of hardened steel. The

The 3-Jaw Combination Chuck, which has both independent and universal jaw movement, offers definite advantages over the plain type 3-Jaw Chucks, which have universal movement of jaws only. With the Combination Chuck, the jaws may be individually offset to meet irregular shapes and then operated with universal jaw movement for repetitive chucking.
Top Jaws are mounted on sliding members to accommodate a variety of diameters. They may be reversed or removed entirely to permit the mounting of special top jaws or fixtures. For Top Jaw Data, see Pages 3, 4, and 5 of this section.

These jaws are made from hardened alloy steel. The bottom and tops of the jaws are ground to maintain a level between the table surface and the work. They are provided with permanent keys and may be secured in any one of numerous positions on the sliding member according to the required work diameter. It should be noted that these, like other Bullard Jaws, are designed to be readily removed or reversed for various conditions of chucking requirements.
Where jaws are subjected to extremely severe service and for gripping rough, unfinished surfaces, these jaws are recommended.
Filler blocks, in many cases, are a valuable adjunct to all top jaws. See Page 11 of this section.
For holding work on finished surfaces, we suggest the use of Bullard Soft Jaws as illustrated on Pages 4 and 5 of this catalog section.

The Bullard 3-Jaw Combínatíon Chuck has both índependent and uníversal movement, and offers definíte advantages over the plain type 3-Jaw Chuck, whích has universal movement of jaws only. Wíth the Combinatíon Chuck, the jaws may be indívidually offset to suít írregular shapes and then operated with universal jaw movement for repetítíve chucking.
The Bullard 3-Jaw Combination Chuck is made for the 30 and 36 Cut Master Vertícal Turret Lathes. It may also be supplied, but ís not recommended for the 42 machíne.
Top Jaws are mounted on slídíng members to accommodate a varíety of díameters. They may be reversed or removed entírely to permit the mountíng of specíal top jaws or fixtures.
