 Metal slitting saw are
manufactured at out modern and state of art plant situated at Pithampur Dist. Dhar MP
India. A team of dedicated technocrats meticulously control each phase of the
manufacturing process so that quality and precision are ensured all times.
DECOSTYLE SAWS have the following exclusive features.
- Made from imported High Speed Steel .
- Controlled heat treatment for uniform hardness and excellent metallurgy.
- proper tooth geometry suiting concentricity, run out and flatness.
- Ground form the solid teeth for improved saw life.
RANGE
DIAMETER 200 MM to 500 MM
THICKNESS 1MM to 5 MM
MATERIAL
| For most of the general applications saws are made from HSS
M-2(DMo5) grade. We also make saws from HSS M-35 (Co5) grade for critical cutting
applications depending on the customer's requirements. |

TITANIUM NITRIDE COATING
The Tin coating of Saw blades is carried out in vacuum furnace where by the PVD process
(physical vapor deposition) titanium is vaporized and reacts with nitrogen gas. This
deposits on saw blades a gold coloured, very hard layers of TiN with thickens of 2-4 /um.
Decostyle Tin coated Saw blades offer clear advantages compared with non-surface treated
bright circular saw blades.
Some of the advantages are
- Higher Cutting Speeds and feeds(50-00%)
- Longer service lives (50-200%)
- Less friction resistance and less wear.
- Lower tooling cost
- Higher efficiency, in particular on automatic sawing machines.
RECOMMENDED TOOTH FORM
TYPE A Straight - For fine machining work, pitches ranging below 3 mm
TYPE AW ACME Straight - A Variant of above
TYPE B Curved teeth - most common tooth form used on cutting thin cross
section tubes, pitches up to 4 mm
TYPE C - HZ Heller teeth - Alternately roughing and beveled teeth for
cutting large sections.

PRECAUTIONS FOR BETTER LIFE
Ensure that the saw teeth are ground properly before mounting it on the arbor.
Ensure that the arbor does not have excessive play.
Saw tooth should not be loose on the arbor.
Clamping flanges is to be tightened properly.
Job should be clamped properly. Play in gibs should be minimum.
Avoid use of excessive high feed rate and rapid traverse.
Ensure the use of proper and sufficient coolant.
