jig borer การใช้

• The jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate ( far more so than a manual milling machine or lathe ).
• The technological advances that led to the jig borer and NC were about to usher in the age of CNC and CAM, radically changing the way people manufacture many of their goods.
• In 1970, Wayne R . Moore wrote about the Moore family firm, the Moore Special Tool Company, who independently invented the jig borer ( contemporaneously with its Swiss invention ).
• Incorporated within the studio are Daniels Schaublin Lathes and Hauser Jig Borer, used to make vital high-precision parts for the watches, which combine with the hand engine-turning equipment, dating back to the 1820s.
• :" In many cases, a jig borer is a'jig eliminator .'In other words, such a machine may be used instead of a jig either when the quantity of work is not large enough to warrant making a jig or when there is insufficient time for jig making ."
• A typical jig borer has a work table of around 400 x 200 mm, which can be moved using large handwheels ( with micrometer-style readouts and verniers ) on particularly carefully made shafts with a strong degree of gearing; this allowed positions to be set on the two axes to an accuracy of 0.0001 inch ( 2.5 micrometres ).
• The boring process can be executed on various machine tools, including ( 1 ) general-purpose or universal machines, such as lathes ( / turning centers ) or milling machines ( / machining centers ), and ( 2 ) machines designed to specialize in boring as a primary function, such as jig borers and "'boring machines "'or "'boring mills "', which include vertical boring mills ( workpiece rotates around a vertical axis while boring bar / head moves linearly; essentially a vertical lathe ) and horizontal boring mills ( workpiece sits on a table while the boring bar rotates around a horizontal axis; essentially a specialized horizontal milling machine ).
