Numerical control knowledge

Numerical control machine tool is IT and the result that photograph of mechanical production technology combines, represented the technical level of contemporary base machine and development trend. In recent years, development of machine tool industry of our country numerical control is rapidder, already had close a hunderd schools of manufacturer of numerical control machine tool at present. To accelerate the development of machine tool industry of our country numerical control, satisfy the need that national economy grows better, the country is being made issue " machinist job revitalizes compendium " in already rated main base machine one of fundamental 4 keys domains, and main base machine basically develops numerical control machine tool namely. "95 " the development policy that reachs machine tool of numerical control of the our country before 2010 is: The key has arrested 6 kinds of leader (forging press of grinder of numerical control lathe, machining center, numerical control, numerical control bed, numerical control is heavy-duty report machines machine tool and numerical control nicety machine tool) , concentration breaks through numerical control system; Development gains ground model, raise dependability; Inside and outside is united in wedlock, give priority to with me, data of implementation our country accuses machine tool industrialization. "95 " during, the key raises dependability, add variety, gain ground model numerical control system and production of dimensions of economy of implementation of numerical control machine tool. To 2000 breed of numerical control machine tool develops 1000 kinds, among them 100 kinds reach level of the international at the beginning of 90 time. The average time to failure of numerical control machine tool and numerical control system achieves 10000 hours, produce per year a quantity to achieve 20000, gain ground model the product is main home of base oneself upon. The system of ownership of industry of current machine tool builds a business, transforming idea, improve knowledge, everything needs to set out from the user, add variety, improve quality, reduce cost, strengthen after service, satisfy the need of the user better. Hope broad user chooses machine tool of homebred numerical control morely heartily also at the same time, raise precious opinion more. Numerical control machine tool has the following and apparent characteristic: 1) agree with the treatment of complex abnormity spare parts. 2) implementation computer control, eliminate factitious error. 3) can come true to precision is compensated and optimize control through computer software. 4) center of machining center, turning, grinding center, report machining center have a knife library and the function that change a knife, decreased to hold clip number, rose to machine precision. 5) numerical control machine tool makes machining equipment increased flexible the characteristic that change. Flexible treatment agrees with not only much breed, medium small lot production also agrees with big batch production, and can finish two kinds alternately or more is planted the treatment of different spare parts, increased the function of automatic shift work, can realize the operation of nightly and unmanned guard. By machine tool of a few numerical control (machining center) of composition flexible production system (FMS) have taller flexible automation makes a system, include to machine, assemble and examine wait for link. Numerical control machine tool can differentiate for 3 administrative levels: 1) high-grade model numerical control machine tool: It is to point to degree of the much axle control that processes complex form or working procedure concentration, automation the numerical control machine tool with tall, flexible height. 2) gain ground model numerical control machine tool: Have man-machine interaction function, application is wider, price moderate, say normally for machine tool of complete function numerical control. 3) machine tool of economy numerical control: The structure is simple, precision is medium, but low-cost, can satisfy the treatment that general precision asks only, can machine the linear, diagonal with simpler appearance, circular arc and belt whorl kind spare parts. Choosing numerical control machine tool to need the principle that follow is: 1) practical: It is to show machine tool of clear numerical control comes to a medium which to solve production or which a few problems. 2) economy: It is to show chooses numerical control machine tool is satisfying the condition that machines a requirement to fall, pays price is most of economy relatively reasonable perhaps. 3) maneuverability: The numerical control machine tool that the user chooses wants to suit with the operation of this enterprise and maintenance level photograph. 4) stable dependability: It is the quality that points to machine tool itself, the stability when product of choice famous brand can make sure numerical control machine tool works is reliable.
