Quaife’s ever expanding portfolio includes close-ratio gearkits, sequential gearboxes, automatic torque biasing limited slip differentials, uprated halfshafts, axles, steering racks and much, much more. Operating in a dynamic, competitive sector, Quaife boasts an unparalleled depth of experience in drivetrain requirement analysis, design and production.

Quaife boasts two advanced CNC equipped facilities.

Established in 1965, RT Quaife Engineering LTD have been providing engineering solutions to customer problems for over 50 years, and continue to do so today in our two Kent factories with a combined floor space of over 50,000 sq ft. Whilst we are best known for our sequential gearboxes and Automatic Torque Biasing differentials in the motorsport world, a large part of our business is dedicated to providing expertise from first designs, production runs and aftermarket support to companies from all sectors who have identified a requirement for a cost effective solution to an existing problem.

We provide subcontract support for industries as diverse as mining, military and aviation and our huge continuous investment programme in our two UK factories enables us to turn our attention to almost any engineering challenge.

With advanced 3D CAD/CAM design suite software, robotic 3 – 4 and 5-axis CNC machining centres, CNC gear cutting, tri-coordinate measuring machines and transmission testing facilities operated by skilled personnel, Quaife redefines the boundaries of what’s possible in the field of mechanical precision engineering, with the backing of full ISO9001-2008 quality accreditation.

The technical support and aftersales servicing facilities at Quaife offer easy access to key product information and unbeatable workshop standards allied to competitive pricing. Whatever the customer request, our objective is always to ensure that season after season, your Quaife product continues to deliver winning performance.

Quality Control

As an ISO9001 registered company, quality control is a vital part of engineering and manufacture at Quaife Engineering. Over our two sites we have specialist Quality Inspectors trained to operate all of our temperature calibrated inspection machines.

Our state of the art Gleason 350GMM Gear Checking Machine ensures the quality of our gear cutting profiles. Capable of measuring deviation of a profile to micrometres, this has instigated a marked improvement in the control of gear and spline profiles. All of our staff undergo training to fully understand and meet the needs that the company’s quality management system requires.

Quality Control Capabilities:





The Quaife Design Department, managed by our Technical Director Michael Quaife, is at the forefront of modern mechanical engineering, and can be tasked with solving problems from a blank sheet or simply adding our expertise and influence to existing ideas.

Our team use Solidworks for CAD modelling and can accept your drawings and models in all common formats. Our drawing library is held securely on our internal servers and used to hold existing and archived drawings, whilst recording all changes and up-issues as they occur.


Gear Cutting

gear cutter

Our latest acquisition, the Leibherr LSE380 Helical Shaper is now fully commissioned in our Sevenoaks factory and is capable of complex shaping including internal splines. As well as this, we also have a Leibherr Vertical Hob with auto-loading function, and a further ten hobbing machines, 5 shaping machines and 2 Maxicut Rack cutters. We can cut gears up to 0.5m in diameter and have a huge range of tools to suit a very large number of tooth forms and sizes. Once cut, we use our Gleason Gear Measuring Machine to check the newly formed profile to an accuracy of up to 1µm depending on your exacting requirements.

As a specialist in transmission components, Quaife are expert in gear cutting techniques and can offer advice and technical expertise on the science behind this complicated area.

Gear Cutting Capabilities:




Across our two factories in Kent we have 19 CNC lathes, four of which have up to 1m length bar feeders and live tooling. Our two Star SR32J sliding head machines have 3m bar feeds accommodating diameters up to 36mm and can quickly produce complete complex milled and turned parts without the need for secondary handling. This is achieved by the part moving, (not the tools), so that they are always cutting at the face of the guide bush where there is the most rigidity. These machines are designed with large batch quantities in mind and are fitted with tool breakage sensors and tool management software, so can run ”out-of-hours”.

All our lathes are purposefully selected to suit our purposes and include Turn/mill centres, 4-axis machines and twin spindles. We also have a further 3 manual lathes for small one off jobs and prototyping.

Whether you need specific one off parts, or production runs of thousands at a time, we have the machinery to cope.


Turning Capabilities:




With 20 Mills at our disposal, we have a great choice of machinery available to us. Included is our Doosan HP6300 with 7 pallets and an automated tool change rack of 120 tools, and a 36 pallet FMS line with three vertical machining centres, each with a further 120 tools. Our 4-axis machines are set and operated by our skilled in-house staff and all work is checked to the highest standards in our quality inspection suite. To assist with our quality control, all our CNC Mills are fitted with Renishaw tool probes which cuts down on setting time and makes it possible to monitor the tool for wear / breakage in process. Our Doosan HP6300 and NHM6300 are also equipped with Renishaw spindle probes and their Inspection Plus software. This enable the datums of the part to be qualified every time and to also check critical sizes in process, with the ability to automatically alter the tool offsets and re-run the part.

Milling Capabilities:


Cylindrical Grinding


Our two new Studer cylindrical grinding centres are complimented by our existing two Jones and Shipman machines and between them provide the perfect solution for cylindrical grinding. With high throughput capacity and the ability to grind with exceptional accuracy, our grinding centres are an excellent resource. They feature the ability to interpolate multiple radii in a single shaft and therefore save valuable time and consumables compared with other grinding machines.

Grinding Capabilities:




Quaife are specialist engineers and own two broaching machines with tooling in excess of 250 broaches. We offer broaching services to a number of third parties as a sub-contract operation and can turn around orders very quickly.

Broaching Capabilities:


Spline Rolling

When forming splines in shafts, the strongest way to achieve this is through spline rolling. The process of spline rolling compacts material into a specific profile between two guided plates and creates a significantly strengthened tooth form when compared with the process of hobbing or milling a spline where material is removed instead. Our Ex Cello Roto-Flow spline rolling machine features an auto-load function and can form a spline in a shaft in a matter of seconds. Perfect for drive shafts or any shaft where a specific fit is required.

Spline Rolling Capabilites:


CNC Straightening


Our Galdabini CNC straightening press can accept simple profile shafts of up to 30mm in diameter and 1m in length, or more specific profiles with custom tooling.

Straightening Capabilities:


REM Super finishing


Do you struggle with surface pitting on contact surfaces? One of the possible explanations is an uneven layer of lubricant between the components. Uneven oil distribution can occur on a microscopic level where surfaces are left as a ‘rough’ finish. Space in our REM superfinishing machine can be rented from us at excellent rates and used to superfinish all sorts of products from classic engine components to gears and shafts. The superfinishing process uses an etching agent to remove a very fine layer of material from the surface before a polishing agent is added to the machine and left for up to four hours to bring the component back to an improved surface finish and a high shine. This machine is perfect for recovering worn engine components as well as finishing brand new machined components that require a smooth surface finish. It is also exceptionally useful for show pieces and working components that are regularly on display.

REM Capabilities:


Wire eroding

Wire erroding


Our Soditech AG600L wire EDM (electrical discharge machining) is the ideal engineering solution for low-volume intricate profile cutting. Particularly useful where there is a requirement for forming irregular shapes, modifying or correcting hardened materials or a need for a repeatable spline form on every pass.
