非金属非标准件
标准零部件是指结构、尺寸、画法、标记等各个方面已经完全标准化,并由专业厂生产的常用的零(部)件,如螺纹件、键、销、滚动轴承等等。 广义包括标准化的紧固件、连结件、传动件、密封件、液压元件、气动元件、轴承、弹簧等机械零件。 狭义仅包括标准化紧固件。 国内俗称的标准件是标准紧固件的简称,是狭义概念,但不能排除广义概念的存在,。 此外还有行业标准件,如汽车标准件、模具标准件等,也属于广义标准件
Standard spare parts refer to zero parts, such as threaded parts, keys, pins, rolling bearings, which have been completely standardized in structure, size, drawing, marking and other aspects and are produced by professional factories. Generally speaking, it includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. In a narrow sense, only standardized fasteners are included. The standard parts commonly known in China are abbreviated as standard fasteners, which are narrow concepts, but the existence of broad concepts can not be excluded. In addition, there are also industry standard parts, such as automobile standard parts, die standard parts, etc., also belong to the generalized standard parts.
非标准件主要是国家没有定出严格的标准规格,没有相关的参数规定之外,由企业自由控制的其他配件。非标准件有很多品种,目前没有很规范的分类。大致分类如下:
The non-standard parts are mainly other parts which are controlled freely by the enterprise besides the strict standard specifications and relevant parameters stipulated by the state. There are many kinds of non-standard parts, and there is no very standard classification at present. The general classification is as follows:
金属非标准件:
Metal non-standard parts:
由客户提供图纸,厂家根据图纸利用设备制作出相应的产品,通常是模具居多,公差要求,光洁度都是客户规定的,没有一定的范式。产品从铸造到精加工完全需要相应的质量控制,工序复杂且可变性大,一般成本高于标准件。
Customers provide drawings, manufacturers use equipment to produce corresponding products according to drawings, usually molds, tolerance requirements, smoothness are prescribed by customers, there is no certain paradigm. From casting to finishing, products need corresponding quality control. The process is complex and changeable, and the general cost is higher than standard parts.
非金属非标准件:
Non-metallic non-standard parts:
是一些非金属材料的加工。诸如塑料,木材,石材等,近年来,注塑行业,塑料模具的发展日益精进,曲面设计,编程数控的引用,使得非标加工的成本和公差等级都有了很大的提升。
It is the processing of some non-metallic materials. For example, plastics, wood, stone and so on. In recent years, the development of plastic injection industry and plastic mould has been increasingly advanced. The introduction of surface design and NC programming has greatly improved the cost and tolerance level of non-standard processing.
