Changeable-Point live centers with interchangeable points

The Changeable-Point center ships with a #3 standard 60° male point; other points are sold separately. The taper/thread design lets points be interchanged while keeping accuracy. The range includes a blank point of unhardened 4140 steel and a female point.

Ultimate Multi-Tasking live center

The Ultimate Multi-Tasking live center has a spring-loaded point for lower turret and sub-spindle applications. The spring makes up for the lack of hydraulic compensation found on tailstocks and protects against overloading. It has a 1.25 inch straight shank and 350 lbs load capacity.

How to choose a Royal Products center or collet

Selection starts with the operation and the machine. Turning between centers and grinding use live centers with 2 thru 6 Morse taper shanks, grinding also uses dead centers, and lower turrets and sub-spindles use the spring-loaded Ultimate Multi-Tasking center.

Bar work on CNC lathes uses collet chucks and Quick-Grip collets.

Next come workpiece weight, speed and bar diameter. High Precision Quad Bearing centers carry workpieces up to 5,240 lbs, High-Speed Precision centers run up to 12,000 rpm, and Quick-Grip chucks take bar up to 100 mm.

Live centers and dead centers

Spindle-type and quad bearing live centers are rated up to 6,000 rpm, and the Roto-Shield coolant slinger extends bearing life by up to 300%. The High-Speed Precision center runs on lightweight spindle oil up to 12,000 rpm.

Changeable-Point centers ship with a #3 standard 60° point, and other points are interchanged through the taper/thread design. Threaded dead centers have an extraction nut, and Oil Country Bull Head centers have five interchangeable heads for pipe bores from 1.75 to 15.5 inches.

Quick-Grip and ER collets

Quick-Grip collets grip parallel along the full part length, cover a 0.062 inch range (0.080 inch on QG-100) and are ground to nominal size with a range of ±0.031 inch. Sizes start with QG-32 for 32.5 mm bar.

ER collets come in inch and metric sizes, with 16 slots and 6 micron runout. Low-Profile chucks use standard 5C, 16C and 3J spring collets.

Collet chucks, the MTC chuck and I.D. workholding

Quick-Grip collet chucks change collets in ten seconds; the Accu-Length version is required on sub-spindles for proper part transfer. Every chuck includes a custom-machined drawtube connector.

The MTC chuck combines a 3-jaw chuck, a collet chuck and I.D. workholding and comes in 8, 10, 12 and 15 inch sizes. I.D. workholding covers 0.5 to 3.25 inches, with specials up to 25 inches.
