Winter lanseeraa uudenlaisia hiomalaikkoja, joissa hiomakappaleen paino on huomattavasti kevyempi kuin perinteisissä hiomalaikoissa. Uudessa CarbonForce-järjestelmässä on useita parannuksia, muun muassa lyhyemmät syklit ja parempi tuottavuus.

CarbonForce is a light weight proprietary carbon fibre reinforced polymer core used in large diameter vitrified cBN wheels, offering higher strength than steel at a lower weight than aluminium providing a massive weight reduction of 75% compared to steel-hubbed Superabrasive wheels. Thanks to the lightweight structure, CarbonForce wheels facilitate easy operator handling and with their robust, form-holding carbon fibre core, reduce cycle times due to less wheel changeover facilitating a reduction in production costs. A superior finish is also achieved on component parts and machine life can be extended due to reduced grinding forces on the machine and work piece. CarbonForce Features • Low density/low weight • High strength and rigidity • Low thermal expansion • Excellent dynamic behaviour/less vibrations • Re-usable • Simultaneous machining Benefits • Enables large parts to be ground • Higher wheel speed • Improves productivity • Less deformation • Less geometric errors • Less tool vibration • Better tool life • Better surface finish • Improved handling • Less surface damage • Reduced cost • Environmentally friendly • Increases spindle life time • Faster manufacturing Applications • Outer diameter grinding • Centerless grinding • Camshaft grinding • Gear grinding Markets • Automotive Manufacturers • Gearbox Manufacturers CAM GRINDING Machine: Schaudt Component: Cam, base circle diameter 30 mm Material: hardened steel 100Cr6 Hardness: 62 HRc Allowance: z = 1,2 mm (Diameter) Requirements: 2,5 µm ≤ Rz ≤ 4,0 µm Wheel: 3A1 140-38-8-2S 50 B126 SGC FT1 V40 Parameters: Wheel speed: vc = 70 m/s Tangential feed rate: vft = 10,8 m/min Q’w,max = 44 mm3 /mms Results: Rz = 3,0 – 3,6 µm Parts per dress: 120 cams Case studies CAM SHAFT TUBE GRINDING Machine: EMAG Component: Camshaft tube Material: soft steel Allowance: z = 0,4 to 0,5 mm (Diameter) Requirements: Rz ≤ 6,3 µm Wheel: 1A1-545-210-13 104 B126 VSS 1327 I8SW V360 Parameters: Wheel speed: vc = 105 m/s Radial feed rate: vft = 9 m/min Q’w,max = 11.3 mm3 /mms Results: Rz = 3 – 4 µm Parts per dress: 1800 Grinding cycle time: tc = 18 s (floor to floor)
