We Will Manufacture Your Design
With our versatile range of machining centres...
Gear Grinding (Gleason – Kapp Niles)
High-accuracy gear grinding to DIN 3961/3967 Quality Grade 4e25 and ISO 1328 Q3–Q4. Capable of grinding spur and helical gears from 0.5 module to 16 module, up to Ø850mm. Profile modifications include tip relief, root relief, tip chamfering, and profile crowning. Lead modifications include crowning, eccentric crowning, and end reliefs for optimised load distribution and reduced noise.
Gear Cutting (Gleason – EMAG)
Precision gear cutting to DIN 3961/3967 Quality Grade 7e25 and ISO 1328, covering spur, helical, worm mills, and wormwheels. Features include lead crowning and automated loading, with a module range from 0.4 to 4 module, supporting prototype, development, and production volumes.
Cylindrical & Thread Form Grinding (Fritz Studer)
Precision cylindrical and thread form grinding achieving <0.003mm runout with tolerances of ±0.0025mm. Surface finishes down to <0.4 Ra, with capacity up to Ø350mm and 1000mm between centres.
5-Axis Simultaneous Machining (Mazak)
Advanced 5-axis CNC machining centres equipped with 30 pallets, 145 tools, and Renishaw probing. Capable of machining complex, high-precision components from solid billets of aluminium and steel, supported by 3D CAD and CAD/CAM software.
Turning Centres & Mill-Turn Machining (Mazak – Okuma)
Multi-tasking turning and mill-turn machining supporting bar and billet loading up to Ø900mm, enabling efficient manufacture of complex rotational components in a single setup.
Metrology & Inspection (Mitutoyo – Gleason – ViciVision)
Comprehensive inspection and metrology including gear analytical inspection and Mitutoyo CMMs. We provide First Article Inspection Reports (FAIRs), detailed measurement reports, and full material certification to support aerospace, defence, and safety-critical applications.
Gear Teeth Dimensions
Free Use Online Gear Tooth Calculator + Spline Calculator – A user-friendly interface that displays the tooth profile in the transverse section and automatically updates with your inputs. This allows you to consider factors such as profile shift, undercutting, and tooth thickness.
CAD/CAM
By using 3D CAD models in conjunction with our hyperMILL CAD/CAM platform (OPEN MIND), we generate accurate, efficient toolpaths for complex components and production work.
Gear Design
For more advanced designs of spur, helical, worm, and wheel gears, we use industry-leading software to handle complex problems and conform to international standards. This includes gear design and analysis tools such as KISSsoft. We also design spline gear teeth according to DIN 5480.
Spiral Bevel Gear Design
We produce and optimise Spiral Bevel, Hypoid, and high-ratio hypoid designs in-house, supported by our closed-loop inspection and manufacturing capability. Using Gleason cutting and inspection technology, we can manufacture smooth, accurate, and high load-capacity teeth forms for demanding applications.
3D CAD Design
Using our SOLIDWORKS 3D CAD platform (Dassault Systèmes), we produce models and production-ready drawings to support manufacture and inspection.
Quality and Precision
Quality and Precision form the core of our operations.
We hold a comprehensive range of certifications across our business, including AS9100D for the aerospace industry. Our staff, who are the backbone of our operations, are trained to a high standard.
Exhibitions & Events
