| It’s true, at least for PE-TRA Band saw machines. PET-RA band saws which are 24 x 7 machines, and hence generating heaps of chips, have a basic layout with an improved and efficient catchment area for chips and coolant. All currently produced PE-TRA Band saw machines are integrated with newly designed, more efficient Chip removal system, which effectively produce dry chips and also removes other foreign materials. |
| PE-TRA Band saw’s
basic layout is such that, it effectively collects almost all
the chips and coolant , splashed during cutting operation and guides
it to the chip conveyor. Coolant through blade guide is a feature in
PE-TRA Band saw, which forces most of the chips directly into the chip
conveyor. A chip removing motorized wire brush, rotating at rated speed,
which is installed at a pre-designated angle, also cleans the chips
efficiently and forces it directly to the chip conveyor. All care has
been taken to avoid coolant splash outside the machine working area. |

Improved design of Chip conveyor now makes it possible to easily clean conveyor housing, by removing the Coil or Screw* itself, just through simple maneuvering, during periodic cleaning or maintenance (*Warning- Please Switch OFF the machine before carrying out any such cleaning operation. Please consult machine manual). Then finally a very effective and efficient chip removal system, which removes dry chips and other foreign items, returning the coolant back to the coolant tank, thus avoiding any breakdown and damage to the electrical and mechanical parts. |
| This Screw type chip
removal system, in which Screw is supported at both ends, installed
in a housing which is located at the bottom and lowest portion
of the machine and effectively collecting the chips from the cutting
area and as well as from other portions of the band saw machine. Chip
conveyors Screw’s ‘end coil’ has unique profile which is clearing
chips as well as foreign items effectively, without overloading the
system. Chips are then fed to an outlet or chute, which has a ‘relieve
area’ and then expanded profile over the length and is inclined too
for relevant results. Hence when chips and other foreign articles exits
from chip conveyor outlet, they first comes across a ‘relieve area’,
where foreign materials (like nuts, bolts or metal pieces etc) gets
the space thus avoids any overloading on the Chip conveyor system. As
the chip conveyor screw moves continuously, churning out the chips out
to ‘relieve area’ , which in turn makes the chips and other items
to move, up in extended and expanded area. During this process, coolant
gets back into the tank, making the chips completely dry. |
| Kindly note, PETRA machines tried their best to remove chips and keep the machine working space clean, but as a manufacturer, we always recommend to clean the machine periodically (highly recommended-after every working shift. Please follow Instruction Manual before cleaning) which also helps in keeping the downtime to minimum and enables machine to perform consistently. It is also in the higher interest of the user too. |
