Quality Control

As an ISO9001 registered company, quality control is a vital part of engineering and manufacturing at Quaife. 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.

Design

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

Liebherr

Our latest acquisition, the Liebherr 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 Liebherr 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 experts in gear cutting techniques and can offer advice and technical expertise on the science behind this complicated area.

Turning

Star running 1

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 which mean they can run ”out-of-hours”.

All our lathes are purposefully selected to suit our needs 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.

Milling

Overall view

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 – 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 the 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, as well as to check critical sizes, with the ability to automatically alter the tool offsets and re-run the part.

Cylindrical Grinding

Grinding machine

Our two Studer cylindrical grinding centres are complimented by two Jones and Shipman machines. Between them they 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.

  •     3 Studer CNC Cylindrical Grinders

Broaching

Broaching

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

  •     1 Vertical Broaching Machine with Robot Loading
  •     250+ Broaches

Spline Rolling

GBD 1_1

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. This compares to 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

  •     1 Ex Cello Roto-Flow Spline Roller

CNC Straightening

Galdabini 1

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

  •    1 Galbini CNC Straightening Press

REM Super Finishing

REM

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

  •     1 R.E.M. Super Finishing Machine

Wire Eroding

Our Soditech AG600L wire EDM (Electrical Discharge Machine) is the ideal engineering solution for low-volume intricate profile cutting.
