Modular machine tool is in in the application in small lot production
Modular machine tool is it is a foundation with general component, match the special part that with pressing workpiece specific appearance and treatment craft design and clamping apparatus, semi-automatic or automatic special machine tool of composition.
Modular machine tool uses foreword of much axis, much knife, multitask, much face or multitask commonly the means that machines at the same time, manufacturing efficiency comes higher than general purpose machine tool severalfold a few times. Had been standardized as a result of general component and seriation, can configure neatly according to need, can shorten design and make cycle. Accordingly, modular machine tool holds low cost and efficient advantage concurrently, in large quantities of, mass-produced in get applied extensively, usable in order to form automatic product line.
Modular machine tool is used at machining casing commonly kind or the spare parts of extraordinary appearance. When treatment, workpiece does not rotate commonly, move by the opposite feed of the whirligig of cutting tool and cutting tool and workpiece, will realize aperture of aperture of bore, reaming, Huo, bore with a reamer, bore hole, the circle outside whorl of inside and outside of milling plane, cutting and treatment and end panel. Some modular machine tool use turning head clip to hold what workpiece makes to rotate, make feed motion by cutting tool, also can realize certain swing tower kind spare parts (wait like axle shaft of rear of flywheel, car) outside circle and end panel treatment.
20 centuries since 70 time, as can age dislocation cutting tool, closely milling cutter, bore hole the development that dimension detects automatically and cutting tool compensates a technology automatically, the treatment precision of modular machine tool also rises somewhat. The flatness of milling plane can amount to 0.05 millimeter ／ 1000 millimeter, exterior surface roughness but low amount to 2.5 ～ 0.63 micron; Bore hole precision can amount to IT7 ～ 6 class, pitch precision can amount to micron of O.03 ～ O.02.
Special machine tool is as auto industry arisen and development rises. Certain in special machine tool part is used because of repeating, work up makes current part, produced modular machine tool consequently.
The earliest modular machine tool was made in the United States 1911, use at machining car spare parts. Earlier, manufactory of each machine tool has respective general component level. To raise the interchangeability of the general component of different manufactory, facilitating user is used and maintain, american Ford Motor Corporation and general motors company and manufactory of American machine tool talked things over 1953, decided the principle that general component standardizes modular machine tool, provide the connection measure between each component strictly namely, but did not make a provision to component structure.
