In 2003, Qinchuan Grande cooperated with Jinxi Axle to develop a special grinding machine for CNC axles, which solved the transition arc and outer circle of the axle journal and the dustproof plate seat. The grinding process was carried out with an ultra-wide grinding wheel. finishing. This machine is the first domestic CNC axle grinding machine. It was delivered in 2005 and it has a good effect, which fully meets the requirements of users. Subsequently, Qinchuan Grande seized the opportunity in time and actively contacted the former Ministry of Railways to convene the vehicle manufacturers of the CSR Group and the CNR Group. The on-site promotion meeting was held in the Jinxi axle, which formed a good response in the domestic axle industry.
After many years of communication with different axle manufacturers, Qinchuan Grand Axle Grinder has summarized the new technical requirements and individualized differences of various axle grinding processes. New technical requirements include: new axle machining will be produced on the production line in accordance with the new standards of the Ministry of Railways. Axle grinding requires high precision and automation, final precision data for axle grinding and data communication with the Ministry of Railways HMIS system. From the user's point of view, in addition to the locomotive and bus vehicle manufacturing companies under the CSR and CNR Group, the axle grinding machine customers also have the locomotive section of each railway bureau and the high-power locomotive maintenance base. The production status of different types of enterprises is different and the requirements are different. After years of hard work, the serialization of CNC axle grinding machines was finalized and completed, which can meet the various grinding process requirements of domestic axles. GZ118A and GZ118B CNC high-speed axle special grinding machine, GZ116A CNC axle forming grinding machine (bevel-cut type), can grind multi-step outer circle, end face, arc, and can automatically control the taper by CNC B-axis. The ultra-high-precision continuous automatic multi-axis diameter reduction-suspended on-line active measuring device can be moved axially and up and down to achieve absolute measurement of each shaft diameter of multiple steps. GZ126 and GZ139 CNC double wheel frame axle special grinding machine, which can realize the simultaneous grinding of the outer circle, end face and arc of the two ends of the axle at the same time, using multiple grinding wheels for simultaneous grinding; realize five-axis two linkage, configure Siemens 840D CNC The system controls the feeding and moving of the left and right grinding wheel frames and the head frame rotating shaft, respectively, and the automation degree and processing efficiency are high.
Reputation of quality service tree, market share is the first
Qinchuan Grande insisted on prioritizing the user service of the axle grinding machine, and the user satisfaction remained above 95%. At the same time, it has repeatedly repaired its imported axle grinding machines for customers, which not only demonstrated its strong technical strength, but also won the trust of customers. For example, the Danaobat CNC axle forming grinding machine imported from the Changchun Locomotive Works of CNR Group has experienced serious failures. Qinchuan Grande quickly dispatched personnel to repair and solve the urgent needs of users. Subsequently, Changchun Locomotive Works decided to re-purchase Qinchuan Grande's 1 axle grinding machine and recommended Qinchuan Grande's products and services to the brothers.
Since the delivery of the first axle grinding machine in 2005, it has gradually entered the CSR and CNR Group vehicle factories. After 2009, it has basically replaced the imported products and entered the depots, locomotive sections and high-power locomotive maintenance bases of various roads. . By the end of 2013, Qinchuan Grande's axle grinding machines have been sold to 36 users nationwide, among which typical users include Qiqihar vehicles, Changchun passenger cars, Baotou Beichuang, Jiang'an vehicles, Nanjing Puzhen locomotives, Guangzhou vehicles, Ziyang locomotives and other vehicles. The backbone enterprises of CNR Group, as well as railway bureaus such as Jinan, Taiyuan, Shenyang, Xi'an, Chengdu, Liuzhou, Xining and Nanchang, have a market share of over 80% and rank first in the country. In 2014, Qinchuan Grande is repairing Tianjin High-powered locomotive maintenance base, Baotou Yiji, Taiyuan North Depot, Xining Railway Branch Qinghai-Tibet Railway Company, Xi'an Depot, Xi'an High-powered Locomotive Maintenance Section, Chengdu High-powered Locomotive Nine users, including Shenhua Group and Huanghua Locomotive Maintenance Center, carefully manufactured 11 CNC high-speed axle special grinding machines ordered by them.
