Precision grinding machinery by Matrix Machine Tool / Matrix Group

Matrix Machine Tool (Coventry) Limited represents an established British benchmark in precision thread grinding and complex gear profile finishing since 1913.

Operating under the Matrix Group engineering brand, the factory combines heavy vibration-damping grey iron structural beds, precision ball screw mechanics and advanced digital NC architectures from Fanuc and Siemens.

Matrix equipment is deployed across aerospace manufacturing, turbine fabrication, defense machinery and heavy automotive transmission plants producing critical lead screws, precision worms and industrial speed reducers. Structural design choices deliver reliable sub-micron dimensional repeatability.

External CNC thread grinding capabilities of the TE series

The Matrix external thread grinding portfolio spans the TE-0550, TE-0850 and extended TE-2250 heavy-duty models.

Designed for high-accuracy finishing of thread ring gauges, ground lead screws, worms and ballscrew shafts up to 350 mm in outside diameter, these machines feature rigid spindle platforms that preserve pitch uniformity over extended travel distances.

Integrated CNC rotary diamond disc dressers with automatic wear compensation maintain profile fidelity without requiring manual intervention. High-torque motorized grinding spindles with continuous thermal stabilization prevent work distortion during precision finishing runs.

Internal thread grinding of ballscrew nuts with the TI series

Internal thread grinding machines in the TI series (models TI-0860, TI-3060 and TI-5060) are designed for precision machining of internal ball track grooves within ballscrew nuts and tooling bushings.

A swiveling wheelhead allows operators to dial in exact helix angles while retaining exceptional assembly stiffness. High-frequency internal electric grinding spindles operating at speeds up to 60,000 RPM establish optimal surface cutting velocities for CBN and vitrified wheels.

High-resolution optical linear glass scales with 0.1 micron increments maintain consistent radial and axial tolerances across production batches.

Profile gear tooth form grinding on GH and GV machinery

Matrix GH horizontal and GV vertical gear form grinders specialize in finish profile grinding of spur and helical external gears exhibiting involute or cycloidal geometry.

The machinery is sought after in prototyping shops and gearbox production environments where rapid setup changes between work geometries are essential. Dedicated Smart Gear software permits complex tooth topology tailoring, including longitudinal crowning and tip relief modifications.

Rotary diamond dressers operating with standard M12 profile rolls ensure faithful reproduction of calculated involute forms, reducing operating noise in heavy drivelines.

High-throughput continuous generating gear grinding on GVC platforms

The GVC-0500 gear grinding platform implements continuous generating grinding utilizing multi-start vitrified abrasive worms. Synchronized motion control coupling the tool spindle and work rotary table through direct-drive torque motors eliminates kinematic errors typical of mechanical gear trains.

A dual-station rotary indexing worktable allows concurrent loading of unfinished blanks during the active grinding cycle, reducing idle auxiliary time.

Built-in dynamic auto-balancing devices and acoustic emission touch sensors safeguard workpiece metallurgy and eliminate thermal burns on hardened tooth flanks.
