BURR FREE COLD SAW FLYING CUT OFF (COC)

This concept is design, developed and manufactured for the first time in India&suitable for tubes from 3NB to 10NB upto 8 mm thickness and maximum speed of 45met./min can be achieved for 3tube.
Coated HSS cutters of diameter 450 mm after re-sharpening can also be used to cut 4.50 mm thick wall Tube/Pipe with our newly developed Gear Box&PLC Program. A new coated HSS saw blade can cut above 12,000 nos of dia 25 X 1.6mm.Worn-outreduced saw diameter upto 330 mm can be used to cut Tubes of 32 mm OD,means 20 to 25 re-sharping.After re-sharpening around 3000 cuts*can
be obtained means around 50,000 to 65,000 cuts*(approximately 150 cuts per USD for diameter 25 mm X 2 MM thich tubes by a Coated HSS saw blade for medium mill speed.

Mill Speed with TCT saw

Dia 25 mm x 2 mm Thick

=120 MPM

 

Dia 115 mm x 6.0 mm Thick

=  35 MPM

Mill Speed with HSS saw

Dia 25 mm x 2 mm Thick

= 75 MPM

 

Dia 115 mm x 6.0 mm Thick

= 20 MPM

Connected power

44 KW as against conventional using 95 KW

 

Cost of machine can be recovered only on power cost saving within 2 years.

Cost per Cut 150 to 175 cuts per USD for Dia 25 mm x 2 mm thick with HSS saw Blade.HSS saws can be esharpened for 15 to 20 times means more savings on tool cost.

Cut Length Accuracy

+/-2 mm.
