Additional Equipment For CNC Borers


Gun Drilling Atachments

All of our milling machines have the equipment for gun drilling.

Our gun drills range from 0.125" diameter up to 1.250" diameter. In some cases, we can drill up to 50" deep.

CNC Contouring Heads

All thirteen machines have use of either CH8, CH16 or CH26 Davis contouring heads for contour boring and turning profiles, grooving and screwcutting.

CNC Outfacing Bars

These bars are used for the production of valve seat pockets and cover a wide range of sizes to suit all oilfield valves.

CNC Rotary Tables

5 off CNC rotary tables up to 39 inch DIA with face plate attachments up to 60" DIA. These tables can be used for accurate positioning or for power milling operations. The tables can be mounted horizontally or vertically for added versatility.


Internal Milling Attachments

Designed and manufactured at Belmar. These attachments are use for milling internal profiles and drilling and tapping internal holes.


Ejector Drilling

For large diameter, deep hole drilling up to 3" diameter.
