Machining is a process that accurate to
remove material by mechanical machining technology.
The main classification:
Step of working out process regulations:
1) Calculating annual
production program, determine the type of manufacture.
2) Analysis part drawing
and the product assembly drawing.
3) Select blank.
4) Formulation process
route.
5) Determine the
machining allowance of each process, calculating the dimension and tolerance.
6) Identify the equipment
used in each process and cutting tool, jig, measuring tools and auxiliary
tools.
7) Determine the cutting
dosage and man-hour quota.
8) Determine the main
process of technical requirements and test methods.
9) Fill in the process
documents.

On July 15, 2014, the Xiangcheng Quality Supervision Bureau of Suzhou City, Jiangsu Province, jointly with the Suzhou City Metrology and Testing Institute, carried out special surveys on the metering of household water meters in the three residential quarters of Nanshan Tanan County Phase II, Huayue Yuelang, and Kangqiao Creek Bank. This is the first time that the quality supervision department of Xiangcheng District has carried out special inspections of household water meters for residential communities.
The inspectors check whether the household water meter has been installed and used after the first verification. The main inspection is whether each water meter has a compulsory inspection qualified mark; whether there is a production license for the water meter, whether the labeling is complete; whether the water meter seal is in good condition; and whether the water supply company's distribution, installation, and other registration information is complete.
After all four residential buildings in three districts of Xiangcheng District were inspected on the surface of the water meter and verified by the meter users, the water meters were all produced by Suzhou Water Meter Co., Ltd. and verified by the Suzhou Water Quality Supervision and Inspection Station. In good condition, the water meter number specified on the user's data sheet is the same as the water meter number installed on site, and no water meter has been found without the first inspection.
Earlier this year, the General Administration of Quality Supervision, Inspection and Quarantine demanded the implementation of special supervision and inspections for metering of "four civilian meters" for water meters, electric meters, gas meters and heat meters throughout the country. Next, the city's quality supervision department will gradually carry out on-site inspections of residents' electricity meters and gas meters. It is hoped that through inspections, it will promote the first verification and expiration of the four forms of civil use to ensure that the value of civil use four is correct and reliable, protect the legitimate rights and interests of consumers, prevent measurement cheating, and achieve fair and equitable trade.
Mechanical processing have manual processing
and CNC machining two types. Manual processing is means machining
various materials by mechanical workers manual milling machine, lathe,
drilling machine and the sawing machine and other mechanical
equipment. Manual processing is suitable for small batch production,
simple parts. Numerical control machining (CNC) means the mechanical
workers use numerical control equipment, the CNC equipment including CNC
center, milling center, wire cutting equipment, thread cutting machine,
etc. The vast majority of the machining shop machining the parts by
numerical control machining technology. Through programming,
coordinates the parts in the Cartesian coordinate system (X, Y, Z) into a
programming language, the CNC controller of numerical control machine by
identifying and explain programming language to control the axis of CNC machine
tools, automatic removal of material, get the part according to the requirement
and finish machining. CNC machining in a way that is straight artifacts, suitable for
mass and complex shape parts.
Jiangsu Xiangcheng first launched on-site metering inspection of domestic water meters
Guided by: AQSIQ's requirements for the implementation of water meter, electric energy meter, gas meter and heat meter "Civil Four Meters" special monitoring and inspection work across the country, July 15, 2014, Suzhou City, Jiangsu Province City Quality Supervision Bureau In conjunction with the Suzhou Metrology and Measurement Institute, special metering inspections were conducted on household water meters in the three residential quarters of Nanshan Tanan County Phase II, Hualiangyue, and Kangqiao Creek Bank.
