1 JNJ MACHINES PVT. LTD. “ KEY MACHINING JOBS EXECUTED SO FAR”

2 GASSIFIER SHELL WEP MACHINING CTQ: Gassifier main shell cutout machining. Weight 115MT. Complete profile made with 3D programming.

3 RUNNER HUB OF KAPLAN TURBINE CTQ: Machining of concentric bores with in 50 micron. Also indexing of openings in 60 degree. For 50 MW hydro power plant.

4 ASH-LOCK CTQ: Very long cycle time job where the line boring concept is used and maximum length of bore is 1.9mtr. All bores concentricity maintained with in 100 micron w.r.t to each other. Customer inspection is through FARO. IT has boring from Dia 18 to Dia 560

6 CONDENSER TUBE PLATE DRILLING FOR BHEL BHOPAL CTQ: Condenser tube plate 40 mm MS + 8 mm SS cladding, dia mm hole which requires Ra 3.2 finish, holes. For 770 MW super critical nuclear power plant.

7 TILE PLATE FOR ISRO – MARS MISSION CTQ: 10mm thin aluminum sheet where after machining of 400 pockets the final thickness left was 1mm. Also we made some 1500 holes of M1 to M2.5. Complete plate parallelism was in 20 micron.

8 TURNING OF SHELL OF PETROBAS CTQ: Maximum dia job that we have done in VTL- 5400mm. Made both side lip and NUB.

9

10 TUBE SHEET CTQ: Flatness required with in 50 micron all over.

11 DC Gasket for ammonia convertor CTQ: Very thin section requires delicate handling and machining. For this section concentricity required was with in 50 micron.

12 DOVE MACHINING FOR CALTIM CTQ: Complete spherical machining, we also had to ensure that thickness to dome should not go below 120 mm at any point.
