TURRET LATHE

TURRET LATHE TURRET LATHE IS A FORM OF METALWORKING LATHE THAT IS USED FOR REPETITIVE PRODUCTION OF DUPLICATE PARTS (WHICH BY THE NATURE OF THEIR CUTTING PROCESS ARE USUALLY INTERCHANGEABLE). IT EVOLVED FROM EARLIER LATHES WITH THE ADDITION OF THE TURRET, WHICH IS AN INDEXABLE TOOL HOLDER THAT ALLOWS MULTIPLE CUTTING OPERATIONS TO BE PERFORMED, EACH WITH A DIFFERENT CUTTING TOOL, IN EASY, RAPID SUCCESSION, WITH NO NEED FOR THE OPERATOR TO PERFORM SETUP TASKS IN BETWEEN (SUCH AS INSTALLING OR UNINSTALLING TOOLS) NOR TO CONTROL THE TOOL PATH. (THE LATTER IS DUE TO THE TOOL PATH'S BEING CONTROLLED BY THE MACHINE, EITHER IN JIG-LIKE FASHION [VIA THE MECHANICAL LIMITS PLACED ON IT BY THE TURRET'S SLIDE AND STOPS] OR VIA IT-DIRECTED SERVOMECHANISMS TYPES OF TURRET LATHES THE ARCHETYPICAL TURRET LATHE, AND THE FIRST IN ORDER OF HISTORICAL APPEARANCE, IS THE HORIZONTAL-BED, MANUAL TURRET LATHE. IN MACHINE-SHOP JARGON, THE TERM TURRET LATH...
