Deep hole drilling of steel shafts is often used to manufacture custom built hollow bar, here steel suppliers of hollow bar do not have the available sizes you may seek.
Our Deep Hole Drilling Unique Application
On Centre deep hole drilling,-Deep holes from 25 mm diameter up to 200 mm diameter- Hole depths of up to 3.5metres- Through holes or blind holes (hole at one end only)
Boring of internal diameters for large cylinders and shafts can also be achieved on our larger machines.
Where the internal diameter for large cylinders or shafts, can also be machined to size using a boring bar.
If required, GPM can also machine the outside diameters on large cylinders or shafts to your requirements, as well. Most deep hole drilling requirements tends to be for fluid lubrication or other hydraulic applications.
Since we have honing facility in house, we can maintain H7/H8 tolerances on the drilled bores. We Deep Hole Drill for various industries viz., Oil and gas, mining, defense, space, plastic and rubber, machine tools, Injection Mauling, Blow Molding, hydraulics, etc.
