41 merchandise, taking management and marketings as the point, with the technique supports and serves for backing, insist can keep on to develop the road and will is a kind of to match the our country state of the nation to develop number to control the technique and industries of total strategy.

1.1Take science and technology innovation as to lead first

The number in China control technique and industry through more than 40 years of development, from did not have from ushering in to digest to own the independent independent copyright of oneself, obtain the very big progress. But look back this several decades of development, can see us at count to control the progress of the realm to mainly still press a little bit foreign mode, press department a ground development, the real creative composition is not much. This kind of situation is developping the start stage of the initial stage, is not scandalous. But went to the world to count to control the strong hand, such as the wood's today and knowledge-based economy, and will soon ascend the new century of satge, this normal regulations path of the very difficult line. For example, at the abroad imitate servo quick dated, we start make to imitate servo, have not yet wait we share the steady market, having already fallen behind in the technique; At the abroad beat into the numerical type that the pulse drive is servo the our country market, we come after to make this so-called numeral servo, but did not become the big market scale up to now; Foreign develop numerical type is servo to use the network( pass the fiber optic cable etc.) to control with number to equip the conjunction recently, we come after to develop this kind of system again, the prospect is still not optimistic. This kind of always follow at the other people walk behind, press the abroad to already have the control and drive the mode to develop domestic the number controls the system, after technique up difficult do not need to want the chiyi, and foreign company at our country inshore establish the graduate school and produce the factory, practice to develop right on the spot, produce right on the spot and sell right on the spot, make our product at the function price compare up have already had no many big advantages more and more, so want to further extend the market share, difficulty nature very big.

In order to change this kind of present condition, we must get it deeply and the great theory of the earnest implementation\break, strengthenning the number to control the science and technology innovation of the realm strongly, diligent the research has the practical forerunner of Chinese

42 special features to count to control the technique, building up the oneself gradually independent, the forerunner's technique system. Develop the number of match the Chinese state of the nation to control the product strongly on this foundation, thus become from the number controls the system and counts to control the function parts to category the well-found number controls the whole machine of tool machine of integrity of industry system. Thus, just will not be led long the nose by the abroad, be check and supervision by the other people forever, just use the forerunner probably, practical of number control the product to recover the local market, open the international market, make China of number control the technique and number control the industry to walk in 21 centuries ex- row in world. 1.2 malicious contrive in commercialize

In the last few years the our country number controls the product although the development is very quick, real at stop the feet on the market of not much.In regard to number control system, domestic goods not yet real were accept by the large tool machine factory, so appear the domestic number to control the example that the system useds for the old tool machine reformation more, but new tool machine of material of but few, the tool machine factory produce domestic the number controls the tool machine to use mostly of is all a foreign system. This of course not is a number that says the old tool machine to control to turn the reformation of no account, but the elucidation sees from the angle of the merchandise, our number controls the system and abroads to compare to still exist the very big margin.

In addition to the technique function and functions, the main factor that affects the number to control the system and numbers to control the tool machine to commercialize is more important is a credibility, stability and function. Before, some numbers control the research, the development section of technique and product, pursue of is usually some bodies the index sign( such as how much passage, how much stalk tit move, every minute how much rice enter to the speed etc.) of the technique level now, but little thought of towards affecting some index signs and some small problems of function but, in the energy of stability, the stick, credibility, the function aspect flower of product opposite less. Thus appear levels for some products to authenticate all very high, even also get various big prize.But the product of these high index sign, high performances arrive customer where do not fulfil person's idea because of some small problems but performance, lost the prestige finally, beat not to open for business the field. This elucidation, the product of the

43 kind model of the high index sign, high performance leaves the customer real the practical and dependable merchandise that need is to have the very big distance of, changing into a product of high index sign, high performance a merchandise that has the market still needs to make a great deal of effort of hardship.

1.4 persistences can keep on to develop the road

The development is a next century the importance that business enterprise development strategy, our country the number controls the industry to want to have the big development and also musts insist to walk and can keep on the road of the development. The green is a realization and can keep on the important path of the development, its main thought is to sweep and economize. For this development that should strengthen the green number to control the product strongly, the acceleration promotes the number control the product and counts to control industry and the whole green of manufacturing industries to turn, the main strategic measure should consider following several aspectses: The ① is valid to reduce the product manufacturing and usage pollution of the environment within process. If reduce the number to control a structure of the tool machine, the cancellation casts the pollution to the environment; Control number to the lubrication of the tool machine principal axis to lubricate, spray the oil lubrication with the oil

Quality to rely on

This reliability is in part due to the escalator's advanced technology: the use, for example, of a microprocessor controller with a variable speed converter. A control panel checks the escalator in operation. And there are interfaces for remote monitoring and control. All these features conspire to extend the life-time of components even when confronted by heavy traffic demands. The result is, quite simply, optimum availability and low operation costs.

Focus on service

Optimum availability is also made possible by OTIS' sophisticated spare parts service network which issupported by highly trained service technicians. Sheer scale of our service operation means a faster response and superior availablilty.

User-friendly

The oil tight-welded bottom plate of the truss together with superior-quality insulation permits the Otis 513 NPE to be regularly hose

44 cleaned. What's more the oil separator collects and separates lubricants from the cleaning water.

Adapting to requirements

Communicate that the servo system communicates that servo system is the function parts that the next century counts to control the tool machine indispensability straightly straightly, currently our country return without mature product, so should strengthen the research, development and expansion application .In consideration of the normal regulations tool machine defends the problem of it more difficult resolve, but merge the tool machine to defend the opposite easy, so can develop to respond for the normal regulations structure tool machine a type of difference straight line electrical engineering, for merge the structure tool machine development always synchronous type straight line electrical engineering, thus the grows to avoid short, constitute meet the new high-speed high accuracy of actual applied request to enter to the system. On this foundation, can further develop will drive and pay to accept to match two for an of it suspend the work set.

To meet individual needs, the Otis 513 NPE can be equipped with sophisticated options such as the maintenance-free piezoelectric contact mat, halogen-free wiring and a non-lubricated chain. Automatic handrail tensioning can also be fitted.

Reliability through Passport

Passport is a system which establishes strict checkpoints from planning and development through to manufacture and delivery. Involving both front-line and senior levels of OTIS management, it is a constant reminder that the quality of every escalator is paramount. It is a linchpin in our production and commercial strategy.

自动扶梯

高规格的,有着先进的模块化设计的自动扶梯

OTIS 506NCE自动扶梯是按模块化设计的,因此当它可以进行经济的大批量生产的同时,也可以根据不同特殊规格进行生产。这样的灵活性使这种自动扶梯成为商用自动扶梯最理想的选择。如购物中心,娱乐中心和办公大楼等。

安全第一

OTIS 506NCE自动扶梯安装了许多安全装置,也许是迄今为止最为安全的自动扶梯。其中有许多装置是奥的斯首创的,目前已经成为行业中公认的标准,例如GUARDIAN?裙板。另外特殊设计的楔型扶手带入口保护装置防止了杂物被卷入;一次铸造成型的铝合金梯级保证了梯级的钢性。更重要的是梯级与裙板之间的间隙不仅能保持不变,而且远小于规范的标准。事实上在安全的领域上,OTIS 506NCE自动扶梯不但完全符合所有规范,而且大大超越了规范。

质量控制使产品可靠

乘坐的舒适感和产品的可靠性是通过高质量的部件和专业的装配来达到的。我们在这两个方面上设定了严格的标准并坚决予以执行。我们保证每一块梯阶板都通过测量,并执行了严格的装配控制,对制造的每一步骤都控制在严格的误差范围内。扶手的钢度是通过连续的玻璃支撑来保证的,由于在导轨上包有一圈聚合物,摩擦力和扶手的磨损程度得以降到最低。.2 在商品化上狠下工夫

近几年我国数控产品虽然发展很快,但真正在市场上站住脚的却不多。就数控系统而言,国产货仍未真正被广大机床厂所接受,因此出现国产数控系统用于旧机床改造的例子较多,而装备新机床的却很少,机床厂出产的国产数控机床大多数用的都是国外的系统。这当然不是说旧机床的数控化改造不重要,而是说明从商品的角度看,我们的数控系统与国外相比还存在相当大的差距。

影响数控系统和数控机床商品化的主要因素除技术性能和功能外,更重要的就是可靠性、稳定性和实用性。以往,一些数控技术和产品的研究、开发部门,所追求的往往是一些体现技术水平的指标(如多少通道、多少轴联动、每分钟多少米的进给速度等等),而对影响实用性的一些指标和一些小问题却不太重视,在产品的稳定性、鲁棒性、可靠性、实用性方面花的精力相对较少。从而出现某些产品鉴定时的水平都很高,甚至也获各种大奖。但这些高指标、高性能的产品到用户哪儿却由于一些小问题而表现不尽人意,最后丧失了信誉,
