Dalian DMTG spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Dalian Machine Tool Group (DMTG) spindles and motor spindles — one of the oldest and largest machine tool manufacturers in China.
Dalian Machine Tool Group, a historic leader in Chinese machine tools
TLDR: Dalian Machine Tool Group (DMTG), founded in the city of Dalian, is one of the oldest and best established machine tool manufacturers in China, with two large production sites covering more than 1.5 million square metres, supplying a broad range of CNC lathes, machining centres, boring machines and gear hobbing machines.
Dalian Machine Tool Group (DMTG), recognised as one of the oldest and largest machine tool manufacturers in China, has established itself as a major player in the global machine tool industry since its foundation in Dalian. With two large production sites covering more than 1.5 million square metres, the company supplies a broad range of products: CNC lathes, turning centres, machining centres, conventional lathes, boring machines and gear hobbing machines, together with numerous research bases and centres dedicated to CNC machine tools and robotic speed reducers.
This breadth of range has made DMTG a recognised choice for companies across a wide spectrum of industries, from automotive to aerospace and heavy machinery, equipping small workshops as well as large production plants. That widely distributed fleet raises a concrete maintenance question: access to original parts from Europe is not always immediate, and that is precisely where an independent workshop able to restore a DMTG spindle to its original tolerances saves a machine replacement.
A range of DMTG spindles from 500 to 6000 rpm, in solid cast iron structures
TLDR: Dalian machine tools generally use a solid cast iron structure combining strength, stability and vibration damping, with spindles whose rotation speed typically ranges from 500 to 6000 rpm depending on the model, and configurations that can include a high number of controllable axes.
Dalian machine tools generally use solid cast iron as the base material for their product structures, a choice combining strength, stability and vibration damping, particularly well suited to precision machining. DMTG spindle speed varies with the model and specification, generally between 500 and 6000 rpm, with some models reaching higher speeds to meet specific machining requirements.
Spindle diameter reaches substantial dimensions on the lathes in the range, allowing bulky and complex workpieces to be accommodated — some lathes offering a 76 mm spindle diameter so the internal cavity of the part can be worked directly through the spindle. The most advanced Dalian machine tools include a large number of controllable axes to meet complex machining requirements, with some CNC lathes counting up to 12 combined axes (servo axes, adjustable axes, twin-disc axes), allowing multi-form, high-precision machining.
