Matrix spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Matrix spindles and motor spindles. Matrix is a Coventry (UK) manufacturer renowned for its internal and external thread grinders and its gear cutting and gear grinding machines.
Matrix, a British builder of thread grinders
TLDR: Matrix Machine Tool (Coventry) is a manufacturer founded in 1913, known since the 1930s for its precision thread grinders. According to the trade press (2020), the company belongs to the Taiwanese Hiwin group.
Matrix-branded machines originally came from the Coventry Gauge & Tool Company, before the brand passed to the Churchill-Matrix group. Former products included thread and gear grinders, cylindrical and surface grinders, tap and die grinding machines and a few specialised lathes. The company moved in October 2019 into a plant of around 5,000 m² (54,000 ft²) at Coventry Business Park. Its current range, according to the trade press, includes:
- external thread grinders with 500, 800 and 2,250 mm between centres
- internal thread grinders for bore lengths of 100 and 250 mm
- gear and profile grinding machines, hob sharpening machines and bevel gear cutting machines
- CNC gear cutting machines from sister company Matrix Precision (Taiwan)
- automatic loading options, including robots
The markets cited are aerospace, automotive, medical, oil and gas and general subcontracting. A TC106 double-column surface grinder was also shown at EMO. See also our Hiwin page.
Thread grinding spindles
TLDR: Spindle specifications for Matrix machines are not published in the sources we consulted: power ratings, speeds and bearings are to be confirmed in our quote.
On a thread grinder, the profiled wheel and the workpiece must stay perfectly synchronised: play or runout on the Matrix spindle ends up on the pitch and profile of the thread. Matrix builds its machines to order, with laser-checked bases that are then hand-scraped (5 m slideways scraped to 5 µm on the 2,250 mm grinders). Older machines are also found under the names Matrix, Coventry Gauge & Tool or Churchill-Matrix.
