What is a Brown & Sharpe machine?
Brown & Sharpe screw machines had been a cornerstone of American manufacturing for many decades, known to be the best productivity solution for many turned bar products. The Brown & Sharpes were built as single spindle automatics, designed to use form tools and special cams.
How does screw machine work?
A screw machine functions with a disc cam, which is a rotating piece used to transform rotary motion into linear motion or vice versa using either a single spindle or multiple. Because a screw machine operates with close spindle collets, deflected debris is reduced to minimal or none at all.
What is a Swiss screw machine?
A Swiss screw machine is an automatic lathe that allows for production of high precision parts in high volume. CNC Swiss screw machines give Swissturn/USA the ability to deliver the small, high precision parts necessary for the manufacturing of critical components.
What is a screw machine operator?
A screw machine operator oversees a machine that produces screws to be used in various construction projects. It is important to oversee the results of the screw machine and make sure that the screws meet quality control standards, as many structures depend on screws.
Is Brown and Sharpe made in the USA?
Brown & Sharpe brand coordinate measuring machines including the Global and ONE CMM series are manufactured in North Kingstown, Rhode Island by Hexagon Metrology, Inc., the U.S. based entity of the global Hexagon Metrology group.
Is Brown & Sharpe still in business?
In 2001, the assets of Brown & Sharpe Manufacturing Co. were acquired by Hexagon Metrology (renamed to Hexagon Manufacturing Intelligence in 2016). The brand name “Brown & Sharpe” has generally been replaced by Hexagon on most products, yet the spirit of innovation and quality espoused by its founders lives on today.
Is a screw machine a lathe?
A screw machine is a type of lathe used for the precise shaping of hard materials (usually metal) into specially designed components. Typically, this equipment works by rotating a workpiece at high speeds and allowing it to be operated on by various changeable cutting tools.
What does a screw machine make?
Screw Machine usually refers to an metal working lathe, either single or multi spindle used to produce small to medium sized machined parts in medium to high volume quantities. The term “screw machine” is confusing since a screw machine doesn’t actually produce most of your common screws.
Why is it called a Swiss screw machine?
Essentially, a Swiss machine shapes components by holding a workpiece from the ends and middle while tools sculpt the workpiece from multiple sides. The machine’s name comes from its origin: Swiss watchmakers created it to make tiny, precise screws.
Is Brown and Sharpe still in business?
When did Brown & Sharpe go out of business?
The company was originally located in downtown Providence, but moved to this site in 1872, where it remained until 1964, when it moved to North Kingstown. Fourteen of the company’s buildings survive….Brown and Sharpe Manufacturing Company Complex.

Who bought Brown and Sharpe?
The sale price was approximately $170 million, subject to some final adjustments. As a member of the Hexagon group of companies, Brown & Sharpe’s metrology operations will do business as Brown & Sharpe, Inc. and the Brown & Sharpe name will continue to be the prime brand and promoted worldwide.
Why is it called a screw machine?
Threaded parts represent only a small portion of the items manufactured by these types of machines. Prior to the 1840’s “screw machining” was used to refer to any process that involved the manufacturing of screws. When Stephen Finch introduced the turret lathe in 1845, it was called a “screw machine”.
Who invented the screw machine?
Joseph R. Brown
The screw machine was invented by Joseph R. Brown, one of the founders of Brown & Sharpe. The basic idea behind the machine was taken from a turret lathe. This lathe was modified to create a machine that could create the same part repeatedly.
Can a CNC machine make screws?
Screw machining is a type of CNC machining that can be used to create small, intricate parts as well as longer, thinner components that wouldn’t fit securely on a conventional lathe.
How does a Swiss turning Center differ from a conventional turning center?
Unlike conventional CNC lathes where the part is stationary and the tool moves, a Swiss-type turning center allows the part to move in the Z-axis, while the tool is stationary. As shown in the illustration above, bar stock material is turned rapidly within the machine and advanced through a guide bushing.
Who invented the Swiss lathe?
Credit the Swiss watchmaker Jakob Schweizer as the inventor of the Swiss machine in the mid-19th century. He conceived the novel approach of sliding parts along the longitudinal axis of a lathe rather than moving them down the tool post.
Why do Swiss lathes use oil?
: Swiss-type lathes usually require oil as a coolant liquid, while conventional lathes, water. The heat capacity of oil is lower than that of water. This means that the machining oil will heat up faster than water during the machining. Hence, heat gets transferred away from the cutting edge of the tools more easily.
Where is Brown & Sharpe made?
The Brown & Sharpe Manufacturing Company Complex (also known as Darling, Brown & Sharpe; Capital Industrial Center; The Foundry) is a historic factory complex in Providence, Rhode Island along the Woonasquatucket River.
