A lathe dog is a mechanical device typically made of cast iron, steel or aluminum that transmits rotary motion from a faceplate to a workpiece mounted between centers in a lathe. [1] The tail of the dog is rotated by a slot in a driving faceplate, a stud mounted on a faceplate, or sometimes a side of a chuck jaw.
This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make as ...
Lowe's is the second-largest hardware chain in the United States (previously the largest in the U.S. until surpassed by Home Depot in 1989) behind rival the Home Depot and ahead of Menards. [6] It is also the second-largest hardware chain in the world, also behind the Home Depot, but ahead of European retailers Leroy Merlin , B&Q , and OBI .
The faceplate was the ancestor of lathe chucks, an arrangement of three or more adjustable 'dogs' bolted to the faceplate providing a primitive chuck arrangement. The smaller plate in the upper photo is specifically a 'dog face' with slots intended to hold a bent tail dog while the work itself was supported on centers.
Die Back Plate:This plate prevents the hardened Die inserts penetrating into bottom plate. Guide Pillar & Guide Bush : Used for alignment between top and bottom halves of the press tools. Bottom plate:It is used to hold bottom half of the press tool with press slide. Stripper plate: it is used to strip off the component from punches.
Cylindrical grinding (also called center-type grinding) is used to grind the cylindrical surfaces and shoulders of the workpiece. The workpiece is mounted on centers and rotated by a device known as a lathe dog or center driver. The abrasive wheel and the workpiece are rotated by separate motors and at different speeds.
A backplate with threads may screw onto a threaded spindle nose (for lathe work) or onto an adapter plate with the same nose, to be mounted on the table of milling machines or surface grinding machines. This "threaded spindle nose" type of mounting was the typical method in the 19th century through 1930s.
