In 1830, Simon Fairman, developed the first
hand operated chuck
and received a
patent for his invention. His daughter
married A.F. Cushman of Hartford, a pattern maker at Colt Fire Arms.
In
1862, Cushman acquired his father-in-law’s burgeoning business and
began chuck manufacturing at his residence. The original quarters
were soon outgrown necessitating the construction of a new building,
equipped for manufacturing chucks. The company moved to the
facility pictured above in 1914 and continued to thrive through the
years.
A.F. Cushman was succeed by his son and later by his
grandson, R. Cushman. A.P. Sloan was one of the company's
original incorporators became president in 1923. He was
largely responsible for the product design and was
awarded many patents
during his long career. Mr. Sloan was succeeded by
his son and later by his grandson, H.E. Sloan Jr.
Through innovation and product development, Cushman
became the world's leading chuck maker - awarded over fifty patents.
The growth of Cushman was the result of fundamental know-how, developed
over the years, coupled with intensive engineering and practical
experience.
During the 1980's, Cushman Industries wasn't immune
to the challenges seen in the US machine tool industry.
Seeing shrinking markets and changing times, Cushman was acquired in the
mid 1990's by TSD, a division of DeVlieg-Bullard. Under
TSD's leadership, Cushman Industries regained it's footing and
maintained it's market position.
In early 2005, Cushman Industries was acquired by
Republic Drill (Chicago, IL). Republic Drill is a
leading manufacturer of cutting tools with nationwide sales and
distribution. Republic Drill brings a financial stability to
Cushman Industries required to compete in the 21st century.
Also, Republic Drill respects Cushman Industries' proud past and
inherent value to it's customers - offering a complete line of manual
chucks, power chucks,
Combination chucks
"AccraLock" chucks
special purpose chucks, pneumatic and hydraulic actuators, boring
mill jaws, repair parts, service and consulting.
Today, the new Cushman Industries, partnering
with workholding specialists from around the world, stands ready to
provide world-class products and services at competitive prices and
deliveries with the highest levels of professionalism and courtesy.

Cushman introduces new
20-915 Series Quick Jaw Change Chucks
September 6, 2006 - Chicago,
IL
Why Buy Cushman
Counter-centrifugal Power Chucks versus other brands?
Cushman Industries
Quick Change Jaw Chuck is fast and will save you time and money. The
Cushman Quick Change Jaw Chuck is the only Quick Change Jaw Chuck that
is internally counter-balanced to maintain higher jaw force at high rpm.
It is a lever wedge design that maintains high jaw force at speed, plus
this design unlike other counter-balanced chucks has a very low
histerisis. If you look at other brands of Quick Change Jaw power chucks
they are not internally counter-balanced, also notice the master jaws
are very small and lightweight. The function of the lighter master jaws
is less centrifugal force (loss of grip at speed) because the Chuck has
no counter-balance system. With a Cushman counter-balanced Chuck it
utilizes a full size master jaw that allows the use of a full size
standard top Tooling I.E. 1.5 mm 60-degree, Acme or others top jaws
without sacrificing jaw force.
Other Chuck
manufacturers that use the smaller master jaws offer expensive master
jaw adapters that raises the top jaws farther away from the chuck face,
plus the added weight of the adapter increases grip loss at speed. When
you add the extra weight of a standard top jaw the jaw force loss
increases and it may be required to reduce the rpm to avoid losing the
part out of the chuck from lack of jaw force.
- Change Chuck Jaws in
less then 60 seconds
- Accuracy .0005”
- Counter-centrifugal
design for safe high speed turning
- High speed up to 6000
rpm.
- Lever Wedge design for
low historicist.

steel with jaws-ways hardened and ground.
- Heavy Duty master jaw
and jaw way design with more bearing surface, rigidity and longer
life.
- Higher mechanical
advantage requires lower hydraulic operating pressure.
- No special top jaws
required. Uses Standard off the shelf or existing top jaws. I.E.
1.5mm x 60 degree, Acme, and others without jaw adapters that create
additional jaw force loss.
- Master Jaws accept
Warner Swasey style collet pads standard.
- Counter-balance feature
allow high rpm use when gripping thin wall parts.
- Standard .005” Accra-set
adjustment feature
- High low capable if
required.
