Manual flange facing machine
ORBITRUE 19 Manual
ORBITRUE 19 Manual clamps in the flange bore with its jaw chuck, which becomes the axis of rotation. The operator turns the arm by hand while the lead screw feeds the tool slide: at every revolution the insert removes a spiral of material and leaves the continuous spiral finish required on sealing faces.
Compact (331 × 191 mm), it travels in a carrying case and works where a motorised machine does not fit or where no power is available: line flanges, valves, nozzles and small vessels.

Key features
What sets it apart
Internal mounting (ID mount)
The jaw chuck clamps in flange bores from Ø 25 to 152 mm and acts as the axis of rotation: no external brackets, no reference to build.
Facing range 1"–19"
The slide travels along the arm and covers faces from Ø 25 to 482 mm with a single tool.
Lead-screw feed
The tool slide feeds radially on the lead screw, guided by adjustable brass gibs that take up play.
Continuous spiral finish
With a constant feed the insert leaves the spiral (“phonographic”) finish required on gasketed sealing faces.
Indexable insert
Rigid tool holder with a mechanically clamped insert: you change the cutting edge, not the tool.
Fits in a carrying case
331 × 191 mm footprint: it reaches the plant in its case, with manual and test certificate.
