TOPNC spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of TOPNC spindles and motor spindles — the Chinese manufacturer from Shanghai founded in 2007, specialising in multi-axis machining centres and robotic drilling systems for the aerospace industry.
TOPNC, Chinese manufacturer specialising in precision aerospace machining
TLDR: TOPNC (Shanghai, China, founded in 2007) is dedicated to developing CNC technologies and manufacturing advanced machining centres for processing a variety of materials, with a range covering multi-axis machining centres, titanium alloy processing equipment and robotic drilling systems, aimed primarily at the aerospace sector.
TOPNC, based in Shanghai and founded in 2007, is dedicated to developing numerical control technologies and manufacturing advanced machining centres for processing a variety of materials. The product range covers multi-axis machining centres, titanium alloy processing equipment and robotic drilling systems, designed to deliver intelligent manufacturing solutions aimed primarily at the aerospace industry. TOPNC serves above all the aerospace sector with high-precision equipment and bespoke manufacturing solutions, a positioning that reflects deep specialisation in difficult-to-machine materials (titanium, aerospace alloys) rather than a general industrial engineering offering.
A range of spindles for multi-axis centres and robotic titanium drilling
TLDR: TOPNC machining centres use spindles sized for machining difficult materials such as titanium, with multi-axis configurations and robotic drilling systems matched to the throughput and accuracy demands of aerospace manufacturing.
TOPNC multi-axis machining centres use spindles sized to meet the specific constraints of machining difficult-to-cut materials, in particular the titanium alloys widely used in aerospace construction — a material demanding spindles able to maintain torque and rigidity at reduced cutting speeds to limit heating and premature tool wear. The manufacturer's robotic drilling systems pair a drilling spindle with a robotic arm, to automate repetitive drilling operations on complex aerospace structures, with the accuracy and traceability requirements specific to that regulated sector.
TOPNC spindles and motor spindles covered (non-exhaustive list)
- Spindles of multi-axis machining centres for aerospace materials
