slide rest造句

• Bramah patented a lathe that had similarities to the slide rest lathe.
• In the eighteenth century the slide rest was also used on French ornamental turning lathes.
• The first fully documented, all-metal slide rest lathe was invented by Jacques de Vaucanson around 1751.
• The slide rest ( as the earliest forms of carriage were known ) can be traced to the fifteenth century.
• The slide rest lathe was called one of history's most important inventions, although not entirely Maudslay's idea.
• The Holtzapffels developed ornamental turning lathes from the continuous revolution lathe combined with metal-working innovations like the automatic slide rest.
• Most instructors recommend letting one or more of the fingers behind the slide rest lightly on the strings to help mute unwanted vibrations.
• The suite of gun boring mills at the Royal Arsenal, Woolwich, in the 1780s by the Verbruggan family also had slide rests.
• Maudslay perfected the slide rest lathe, which could cut machine screws of different thread pitches by using changeable gears between the spindle and the lead screw.
• A practical and versatile screw-cutting lathe incorporating the trio of leadscrew, change gears, and slide rest was Maudslay's most important achievement.
• In 1718 the tool-supporting slide rest with a set of gears was introduced by a Russian inventor Andrey Nartov and had limited usage in the Russian industry.
• The slide rest was positioned by a leadscrew to which power was transmitted through a pair of changeable gears so that it traveled in proportion to the turning of the work.
• Coupled with the network of engineers he trained, this ensured the slide rest became widely known and copied by other lathe makers, and so diffused throughout British engineering workshops.
• In 1718 Nartov invented what might have been the first lathe with a mechanical carriage and a set of gears ( also known as a compound rest or slide rest ).
• He invented several machine tools, such as the first fully documented, all metal slide rest lathe, around 1751 ( Though Derry & Williams place this invention around 1768 ).
• It is likely that Maudslay was not aware of Vaucanson's work, since his first versions of the slide rest had many errors that were not present in the Vaucanson lathe.
• A misquoting of James Nasmyth popularized the notion that Maudslay had " invented " the slide rest, but this was incorrect; however, his lathes helped to popularize it.
• A critical factor in making interchangeable metal parts was the invention of several machine tools, such as the slide rest lathe, screw cutting lathe, turret lathe, milling machine and metal planer.
• Meanwhile, turning technology was being developed in England where the practice of arresting the work from point to point ( by a division plate ) and applying a revolving cutter ( held in an improved slide rest ) was employed.
• The legend that Maudslay invented the slide rest originated with James Nasmyth, who wrote ambiguously about it in his " Remarks on the Introduction of the Slide Principle ", 1841; later writers misunderstood, and propagated the error.
