In 2017, Linglong Tire, with the support of governments at all levels and the China Petrochemical Federation, followed the national strategic direction and actively responded to the National One Belt and One Road initiative to accelerate the pace of going global. Promote the conversion of new and old kinetic energy, deepen supply-side reform, and successfully develop dandelion rubber tires, 3D printed polyurethane tires, and open large aircraft radial tire research to fill the domestic technical gap. In 2017, the company's production and sales increased at a high rate year-on-year, achieving a historic leap!
Linglong Group and Linglong Tire are both finalists in the Top 20 Chinese Petroleum and Chemical Enterprises
This time, the list is the reaffirmation of the comprehensive strength and industry influence of Linglong Group and Linglong tires. As a member of China's manufacturing industry, Linglong Tire has been striving to master core technologies, build first-class products, build world famous brands, and accelerate the realization of the "Made in China" to "Created in China", from "Chinese Brand" to "World Famous Brand" change!
Reading volume: Source: Delicate tire of: ZebianMachining is a process that accurate to remove material by mechanical machining technology.
The main classification:
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.
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.
