Stage 1 – Manufacturing

Process Department

All Tufcot® composite materials are manufactured on site at our extensive factory in Sheffield, UK.

The process department is the start of the Tufcot material cycle, split into two sections it encompasses the tube or rod manufacturing section and the sheet laminating section

The process starts with a formulation created by Tufcot’s R and D department. These formulations relate to the specific material grades.

Each material grade is comprised of a thermosetting resin system of which we have several to suit the many varied application to which the material is suited.  The resin can incorporate solid lubricant additives such as, Graphite, PTFE or Molybdenum Di Sulphide.

A reinforcing fibre, these are chosen to enhance the properties of the material and again a number of reinforcing materials are available, the choice of fibre used would be application specific.

A very large range of standard mandrel sizes are available accommodate our customer requirements, custom sizes can be quickly and economically produced for special applications.

Once the tubes or rods are produced they go through an initial curing process (green phase). After the allocated amount of time they can be easily handled to move on to a post cure process in a large temperature controlled curing oven.

Once cured, the tubes/rods are ready to be machined or are ready for shipment if the customer has ordered raw material tubes.

Process Department – Laminating

Laminating follows the initial same procedure using the same formulations as the tube and rod production section.

However, this time instead of using a mandrel, it involves a layup process of a certain number of layers of reinforcing fabric impregnated with the specific resin formulation to suit the required thickness, width and length for a finished laminate.

Once the fabric is laid up to the required size and thickness, it’s then put into one of our hydraulic laminating presses.  The laminate is compressed to a set size which also completes the initial curing phase (green phase) the laminate is post cured, the same as the tubes in the curing oven.

Stage 2 – Preparation

Tube/Rod Preparation

Once the tubes or rods have been post cured they can then be removed and are ready for the next phase of machining.

Due to the manufacturing process the Tufcot® tubes have a resin rich outer surface finish.

The initial process is to trim the ends of the tube and remove this surface.  The tube is either ground on our centreless belt grinder or machined on a centre lathe to the required O/D and I/D if necessary ready for despatch to the customer.

Where finish machined components are required the tubes are now ready to go to either our CNC or Manual machining section for further machining into finished rings, bushes or other products.

Laminate Preparation – Sawing and Sanding

Once the laminates have been post cured they are then ready to prepare.

Where a customer requires sheets or smaller pads, the sawing and sanding department trim and sand the laminate to the customers required dimensions.

Once the laminates are prepared they can be shipped to the customer.

If further machining is required they are ready to be passed to the next department to be machined on one of our CNC milling machines or processed on our CNC router.

Strip material is also produced in the sawing and sanding department.

The raw material laminates are cut into the desired widths and lengths using a special cutting machine.

Tufcot produces 1000’s of metres of strip every year.

Stage 3 – Machining

Manual Machining

Our manual machine department has a current capacity to machine up to 2 metre diameter tubes into finished bushes, bearings or rings as required.

Although quite a significant capacity and a good range of machines, we have identified a need to extend this capability further and will be adding further larger machining capability to this important department.

CNC Machining

A great deal of the tubes produced go to our CNC department, finished parts can be quickly and accurately programmed on our Fanuc controlled Doosan CNC’s and can be machined to either our production drawings or the customers own drawing specifications.

Tufcot has more than 10 CNC’s which cover all areas of the machine capabilities, allowing us to go up to 164mm diameter tubes down the headstock, even larger diameters can be accommodated when the tube is held in the chuck, up to a maximum of 800 mm.

Utilising Bar Feeds on some of our CNC’s allows these machine to run independently for large batch production runs and the potential for Tufcot to operate a 24 hour manufacturing operation if the workload requires this.

The finished parts that are often machined from this process include, flanged bushes, wear rings, bearings, spherical bearings and specially designed parts to the customers’ requirements.

CNC Milling & Routing

Tufcot’s CNC Machining Centres, Milling machines and recently purchased large bed CNC router

With a capacity of over 3 metre length and 1.5 metre width allow the raw material sheet or laminate to be machined into wear pads, wear strips and guide strips, bearing blocks, washers or even structural bearings.

These parts typically include holes, grooves and or special machined features that can be quickly completed on these machines.

Stage 4 – Finishing

After the parts have been machined and to ensure any machining flash has been removed, we have a number of deburring machines, this process cleans the edges and removes any flash, creating a more polished, professional finish.

Stage 5 – Final Inspection

Once the finished parts have been completed within the relevant sections of the machine shop, they then move onto the Inspection department.  The Inspection department is a temperature controlled environment where the finished parts are inspected by our experienced Inspectors before being passed to the packing department.

Our Inspection room contains a CMM measuring machine which allows us to measure and accurately record measurements along with externally calibrated inspection equipment, micrometres, Vernier’s etc. to cover all sizes.

Tufcot can offer 3.1 test certificates.  If needed our sales team can provide prices for 3.2 certification when necessary.

This department is crucial as it the final stage where the goods are dimensionally checked but also to ensure the necessary quality control of goods so they meet our internal, and our customers, standards. Tufcot prides itself on our high standard, excellent quality materials.

Stage 6 – Dispatch

The final stage of the Tufcot services and departments is the dispatch area.

This is a large working area, allowing us to prepare boxes, pallets and other forms of packaging and work with our customers to find the most cost efficient ways of packing their goods to reduce costs and waste.

On Time Deliveries

Since 2013 Tufcot has aimed to consistently improve our On-Time Delivery Performance figures via improving our Production Department and reducing inefficiencies through the whole Company.

On-Time Delivery Performance has improved from 57% in 2013 to 98% in 2016. This a remarkable feat when you have to compare the increased workload since 2013 also.

Tufcot is very proud to publish these figures as it shows the progress of the Company over the last few years. This has included numerous investments into new machinery, production techniques and better Operations Management control.

Other Key Departments

Pricing

Tufcot’s pricing department is the first stage before a customer can place an order.

Tufcot aim to send prices back within 24 hours unless there are further questions and discussions on tolerances or the job is a large or complicated job.

Please email sales@tufcot.com if you have any price enquiries.

Research & Development

Tufcot’s Technical and R & D departments have grown significantly over the last few years, our Technical Manager has many years of experience working in the composite bearing industry and is available to answer any technical questions regarding our grades of Tufcot® material, design and tolerance requirements of components, material selection and suitability and advise on the differing fitting methods etc.

The Technical department links in well with the R & D department.  As you can see from the picture, Tufcot has recently invested in a custom built and state of the art Journal bearing Test Rig. This allows us to test and develop further our current material grades but also allows us to plan for the future and develop new grades of material.

Tufcot philosophy is to constantly invest in new Research and Development projects and equipment for us to be able to compete and advance in a very competitive market place.
