Products & applications Finishing Machines clean up motorcycle brake disc rotors
Manufacturing more than 1,500 motorcycle disc brake rotors per week, Northampton- based EBC Brakes is always looking for pro- ductivity gains. One such gain brought with it an additional requirement for deburring. The switch from machining the disc rotors to using laser to create the complex shapes and patterns that are both practical and func- tional on modern motorcycle brakes, created a product that had burrs and sharp edges. While having no effect on the performance of the brakes, these burrs had to be removed for the health and safety of customers and for aes- thetic reasons. Initially this deburring was being done manually in between other opera- tions, which in itself posed a risk of injury in the handling of the discs and was also fatigu- ing and time consuming.
“It did not take us long to realise we needed to find an alternative to hand deburring that would provide the quality of finish and an automated solution to drastically reduce the time taken to deburr these rotors,” says Paul Britchford, EBC’s production manager. Ellesco was confident its Timesavers 42 series would handle both the volumes and the application. The machines have a combina- tion of abrasive belt deburring and rotary disc pad; linishing and deburring built into the same machine. This provides the ability to remove heavy burrs and/or linish the compo- nent using the belt, then breaking the edges, smoothing the surface and deburring using the rotary pad, or combining both in the same operation. With table widths of up to 1,350mm wide, large volumes of parts can be fed through the machine at any one time. For further reassurance that the machine was capable of meeting EBC’s requirements, a consignment of brake discs was shipped to Timesavers in The Netherlands. These trials proved to be a resounding success, with Paul Britchford remarking of the Timesavers machine: “It did exactly what it said on the tin. Once we saw the quality of the parts that were being produced the decision to purchase was a no brainer. You can put a part through the Timesavers machine and it will deburr and apply a small radius to every edge of the component in a single pass. At the same time
Grinding wheels
for larger apps Superabrasives specialist, Engis is offer- ing customers the latest technology in resin bonded diamond and CBN grinding wheels up to 1,100mm diameter. They are designed for maximum productivity in grinding of bearings, and for large scale grinding applications in the aero- space and automotive sectors. The technical specification of these double-sided vitrified and resin bonded wheels has been developed through an extensive R&D programme.
Engis also supplies carriers for these
large, bespoke grinding wheels, which can be manufactured to fit on any OEM grinding machine, as well as a wide range of other grinding products. Engis T: 01491 411117

it leaves the flat surfaces of the discs with a lightly brushed finish, which makes them look better than we were achieving before.” The key feature of the machine for EBC is the large diameter rotary nylon web pad that has abrasive material embedded in its fibres allowing it to act like a giant polishing mop. The gentle action of this disc rounds off the sharp edges without damaging the surfaces. The lack of pressure on the disc eliminates any possibility of them becoming distorted and having to be ‘flattened’ prior to dispatch. In the first three months since the machine was installed they have not had to replace the rotary disc and only one abrasive belt has been used.

Fein is extending its stainless steel range for surface machining by adding a powerful belt sander, a compact pipe sander and a module for industrial automatic grinding. The manufacturer also supplies perforated Pyramix sanding sheets and narrow elastic cylinders and fleece sanding cylinders. The new power tools make the job of precisely sanding pipes and hard-to-reach places easier. The stainless steel range includes power tools and sets of accessories, tailored to the needs of manual trades and industry. The Fein belt sander BF 10-280 E has been developed for machin- ing welded seams on pipes and can be used to precisely smooth corners, edges and profiles and deburr sheet metal.
The Fein pipe grinder RS 10-70 E is equipped with a header which can be swivelled almost 360 degrees. Its clasping angle of 180 degrees allows stainless steel pipes and pipe bends of up to 45mm in diameter to be sanded, satin-finished and polished. The Grit rotary grinding

module GIC rotary-grinds or satin-finishes the outsides of pipes in industrial applications. The module is attached to the GRIT belt grinder GI 75 or GI 150 without any adjustments. Its four transport casters allow for mobile use in the workshop. It is suitable for automatic surface machining of round materials with a diame- ter of up to 130mm.
The GRIT belt grinder range is modular and is said to be quick to retool and upgrade. This modular system is claimed to be unique in the industry with users benefiting from increased flexibility.

suitable for stone A custom spindle motor and applica- tion-specific CNC system from NUM has helped OMAG to create a five-axis machining centre that combines the functions of a former and a lathe for processing stone materials. OMAG’s Blade5 machine introduces a new level of flexibility for processing stone work pieces by supporting capa- bilities including sawing, milling, rout- ing, turning, sculpting and polishing. One of the machine’s key attributes is a high-performance spindle motor with a large peak torque capability of 400Nm. The spindle motor accelerates all aspects of stone processing. The machine - with a large working area of 5 x 5 metres - is also able to create all shapes and profiles direct from CAD/CAM files, making it suitable for one-off pieces or volume production. NUM
