Oil Hole Drilling in Pistons

Suhner manufactures high speed precision machining unit BEX15, with spindle speed up to 23,000 rpm. The present scenario of increasing the production rates in drilling demands high-speed drilling while at the same time maintaining the quality of the drilled holes. Of the many factors that affect the high-speed drilling process, such as speed, feed rate, material of drill and work piece, and drill geometry, the spindle speed in drilling of oil holes for pistons plays a vital role. Everytime a drilled hole in pistons, even with a step bit, there will be burrs around the edge of the hole. It's really difficult to get rid of these burrs.

With the BEX 15 machining unit at 23,000 rpm, Suhner is able to produce exit burr free holes, which will eliminate an additional operation of deburring or cleaning of the holes thus saving extra time and money. The BEX 15 is an excellent machine under the piston oil hole drilling machine and attains very high precision in the fine drilling, consistency and repeatability and excellent cycle time. With additional features of different tool holder options like Collet ER25, ISO30, HSK50 and Weldon. Also it has standard air purge for protection of spindle bearings and coolant through the spindle the rigid BEX 15 unit can cater various needs of mass production. With proven track record over a decade these machining units are being used by most of the leading piston manufacturers across the globe.
