Ceratizit Offers Custom Boring Tool for Heavy Goods Vehicles

Ceratizit’s freeze plug/water boring tool for heavy goods vehicles (HGV) is said to reduce cost and increase performance when producing the holes in cylinder blocks and heads. According to Ceratizit, the tool roughs, chamfers and reams/fine finishes holes in a single operation — even in grey cast iron with EN-GJV450 vermicular graphite.

The tool’s Ceratizit R84 fine-boring indexable inserts feature a brand new reaming geometry specifically designed for exceptional hole finishing. The new positive geometry is said to generate low cutting forces and includes a new chipbreaker that improves chip control. All of which allows for higher feed speeds while at the same time producing a better surface quality. Additionally, the new inserts provide a much longer tool life as compared to their predecessors.

Compared with the conventional machining approach using two tools (one for roughing and chamfering, one for finishing), the Ceratizit solution reduces tool changes down to one, reportedly shortening the cycle time and dropping tool costs by at least 20%. The single-tool strategy also means that having to adjust the different tools precisely in relation to each other is now eliminated.

When it comes to tool setting, the plug-and-play system of the new water plug machining makes reconditioning of a worn tool much easier than with the previous two-tool approach. While users still have to remove the cutting inserts and clean the base body, the insert seat and indexable insert mean that no resetting is required. Users rotate the four-edge insert and screw it back into position, recalculate the length dimensions and print the label or download the latest tool dimensions to the (optional) integrated chip.

The new HGV water-plug machining tool from Ceratizit is available in diameters ranging from 25 to 65 mm. The tool holder is designed and manufactured as a special tool in line with the customer’s length and diameter requirements. The indexable inserts for roughing and fine boring are standard stock products.
