Quality and Precision as Standard
Ondrives combines specialist gear manufacture with CNC machining, engineering design and in-house metrology. We support prototypes, small batches and repeat production of gears, shafts, splines, worms and precision transmission components.
Hobbing and shaping of spur and helical gears, internal and external splines, worms and worm wheels, with crowning where required.
Form and profile grinding from solid or as a finishing operation, including lead and profile modifications for demanding transmission applications.
Closed-loop design, grinding and inspection of spiral bevel, hypoid and high-ratio hypoid gear sets using specialist Gleason systems.
Integrated turning, milling, drilling, boring, gear hobbing and gear skiving, supported by automated production equipment.
CNC turning, sliding-head machining, wire EDM, cylindrical grinding and honing for shafts, housings, blanks and complex components.
Gear and transmission design, CAD/CAM, analytical gear inspection, CMM and optical measurement support controlled manufacture and reporting.
From an existing drawing or a new engineering requirement, our team can support manufacture of precision gears and drive components using modern machining, gear production and inspection equipment.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Using our SOLIDWORKS 3D CAD platform (Dassault Systèmes), we produce models and production-ready drawings to support manufacture and inspection.
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.
AEROSPACE AND ADVANCED MANUFACTURING
Ondrives plans to exhibit in Hall 2 at the Farnborough International Airshow in July 2028. We look forward to meeting customers, engineers and procurement teams at this globally recognised aerospace event.
