Haozhi spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Guangzhou Haozhi Industrial spindles and motor spindles — the listed Chinese manufacturer specialising in the R&D, manufacture and maintenance of high-speed motor spindles, with speeds reaching up to 80,000 rpm.
Haozhi, a listed Chinese manufacturer specialising in motor spindles
TLDR: Guangzhou Haozhi Industrial Co., Ltd (stock code 300503, ChiNext market) is a high-technology company specialising in the R&D, design, manufacture, sale and maintenance of high-precision mechatronic core components, including spindles, rotary tables and spare parts for CNC machines, robots and new energy vehicles.
Guangzhou Haozhi Industrial Co., Ltd, a high-technology company listed on China's ChiNext growth market, covers research, design, manufacture, sale and maintenance services for key functional components for mid- and high-range CNC machine tools, robots, as well as for new energy vehicles and the environmental protection and energy saving sectors. The group strengthened its capabilities by acquiring Dongguan Xianlong Motor Co., Ltd. in 2017 and the Infranor group in 2020. In 2021, the high-speed air bearing spindle developed by the company won the twenty-second China Patent Award, and the manufacturer's electric spindle was selected for the list of "single champion" products of Chinese manufacturing — distinctions that reflect the technical recognition the company has gained in this segment.
A range of very high speed motor spindles, up to 80,000 rpm
TLDR: Haozhi motor spindles cover a wide speed range depending on the series — from 5,000 rpm on manual change models up to 80,000 rpm on high-speed milling spindles — with applications spanning milling, grinding, dental, glass and printed circuit boards.
Haozhi ES series motor spindles, motorised with an automatic clamping system (for example ES 325 in HSK 25 interface), reach 40,000 to 50,000 rpm, with automatic tool locking by pneumatic piston, front and rear ceramic bearings and lifetime lubrication. The DGZ series of asynchronous spindles, usable dry or wet, offers solutions for dental milling, glass grinding and printed circuit board machining, with speeds reaching up to 80,000 rpm for a 33 mm diameter, and runout accuracy of the face and taper bore of 0.001 mm or better. On the TSE series, with liquid-cooled motors, the speed range extends from 1,600 to 45,000 rpm depending on the model, for diameters from 40 to 160 mm. On grinding configurations (SGE series), the spindles cover HSK-C63, HSK-A100 and HSK-A63 interfaces, with speeds from 1,450 to 6,000 rpm for diameters from 155 to 240 mm.
