Autom Special requirements, precise solutions

motive Modern automotive manufacturing relies on the application of high specification materials that are sometimes difficult to machine. Typical components such as engine blocks, cylinder heads or transmission housings put special demands such as wear-resistance and accuracy and – fields of application ideally suited to PCD complex tools from Guhring. On the following pages we present some tooling solutions developed by us for the engine and other automotive components, transmissions and chassis parts.

cylinder head

Highest performance thanks to highly accurate machining Guhring designs and manufactures PCD tools for all machining tasks related to modern high performance engines. Machining componenets such as the cylinder head or crank case requires many closely positioned holes, the machining of which generates high temperatures. Due to such heat there is a risk of deformation of the precision holes. Guhring’s PCD tools possess special cutting edge geometries. The risk of deformation is significantly reduced and accurate holes guaranteed.

MOTOR Cylinder head Water jacket bore This system for chip evacuation is ideally suited for holes when chips are not permitted to enter inside the workpiece. The special geometry of the water jacket drill ensures the chips are directed away from the workpiece. Contamination of the cylinder head is, therefore, greatly reduced. Water jacket bore Finish machining of valve seat insert and valve guide parent metal This solid carbide version offers highest rigidity and is resistant against erosion from abrasive materials. Not adjustable.

The diameter is adjustable with the use of the expansion joint. expansion joint expansion screw The reamer diameter is also adjustable with the use of the expansion screw. Finish machining of valve train guide / insert Not adjustable, however, it is possible to correct the concentricity. Fine adjustment of the reamer’s concentricity is possible with the assistance of 4 adjusting screws on the cutting head. adjusting screws rigid insert seat Finish machining of valve train guide / insert Adjustable. adjusting screws axial and angle adjustment is possible 13 motor Drive ancillary components...

MOTOR Cylinder head Control cuts Spring seat tool This tooling concept combines several tool types and hence reduces the machining time for the spring seat considerably. The application of 1-shot versions must always be individually checked for every machining process.

motor Drive ancillary components Axles and steering Brakes special solutions Aerospace The PCD-tipped option is also available as a solid carbide tool. Finish machining The specially developed cutting edge geometry as well as the arrangement of the cutting edges provide optimal accuracy and short cycle times while maintaining consistent quality. HVA machining This 1-shot version combines the pre- and finish machining for the hydraulic valve compensation bore. The application of 1-shot versions must always be individually checked for every machining process.

MOTOR Cylinder head Camshaft bearing tool z=1 PCD reamer for machining camshaft bearing seats in aluminium cylinder heads. The possibility of axial and radial adjustment of the cutting edges guarantees an individual adaptation to the machining task. With the userfriendly setting philosophy the cutting edges can be adjusted effortlessly from one side. In addition to this product, the adjusting device EV-600 is also available from Guhring to perform the radial and axial fine adjustment of the tool.
