angle heads - GERARDI - #3

Text version of the page

Evolution Line The new Evolution line of Gerardi angle heads has been designed from a technical base derived from 40 years expérience of solving thousands of production problems, finding optimum solutions and always guaranteeing the highest product quality 26 standard angle head types are now offered, designed, built and distributed in more than 50 countries the world over by Gerardi S.p.A., and available with a range of options to complete their application and performance potentials. Main Technical features 1- Minimum thermal expansion and high corrosion résistant treated steel body 2- Modularity: main shaft with interchangeable shank allow an EVOLUTION angle head to be used on other machining centres with different spindle types and sizes. It is also possible to exchange the anti-rotation (arrester) sub-assembly and the input drive taper with no effect on rigidity or accuracy. 3- All spindles are supported by pairs of preloaded angular contact ball bearings with ABEC 7 precision and long life lubrication. 4- Gleason computer based calculations for the Gleason cut spiral bevel drive gears with ground teeth 5- More than 26 angle head types available. 6- Among the new range of angle head types the slim series have reduced weights and overall dimensions. The Slim series are even able to enter a minimum diameter of 39mm. 7- Up to 10 bar coolant through the pin included in the standard heads. Options include feeding coolant at 10 bar though the cutter spindle or at up to 70 bar through the machine. 8- Designed for superior heat dissipation and for sustained periods of high speed operation 9- 100% compatibility with heads installed during the last 40 years (same anti-rotation/arrester pin and stop block dimensions) 10- GERARDI Evolution angle heads have been designed and are manufactured in Italy. They are covered by 1 year warranty. For technical features, performances and standard equipment, please refer to the présent Price List. ATC SERIES NB- MTC SERIES Pag.4 - 32 w ATC angle heads are idéal for CNC machines with automatic tool change and can be automatically transferred from the tool magazine to the machine spindle and vice-versa. The orientation ring and arrester arm support ring are both 360° adjustable to allow the best angular orientation. On FMU heads, the cutter spindle housing can be adjusted at ±90°. If an ATC angle head is not placed into the machine spindle, a locking system prevents shank rotation relative to the head body. Pag. 33 - 38 ^ This range of angle heads is for conventional machines without automatic tool change. MTC angle heads (Manual Tool Change) are manually mounted to the machine headstock through a flange. On FMU heads, the cutter spindle housing can be adjusted at ±90°. www.gerardi.it
