Gears

Gears and transmission components are designed to transmit power efficiently, and every hole drilled in them serves a specific purpose. I have drilled thousands of oil holes in gear teeth, lubrication passages through transmission shafts, and weight-reduction bores in gear blanks. The challenge with transmission components is that they are heat treated after machining. The drilling has to be done before heat treatment (while the material is still machinable), or with special tooling after heat treatment. ...

Gears and splined shafts need oil holes for lubrication. The holes are typically small — 2-8mm diameter — drilled at an angle through the gear body or shaft wall. The position and angle need to be precise to deliver oil to the right location. I’ve drilled oil holes in gears for industrial gearboxes, automotive transmissions, and heavy equipment drive trains. The work requires careful setup and attention to angle accuracy. ...
