Aircraft components are made of high tensile, tough materials like High-Density Special Steel, Titanium and Composites. Sigma Tooling’s offers unique tooling for 5 majors components.
• Rear Cone
• Titanium Center Piece
• Bearing Housing
• Engine Cases
• Manifolds
Zero Run-Out Coupling
Sigma has designed the zero run-out coupling to maintain axial & radial run-out within close tolerance of ±0.005mm. It is rigid because of face butt clamping.
High Positive Tangential-Insert
Sigma tangential cutting insert with tough cutting edge & high positive chip breaker reduce cutting forces.
Boring Head
Boring head is made of special tool steel which is having high tensile strength & high stiffness with unique surface treatment which gives smooth surface, excellent chip flow & increased body life by 30~35 % as compare with regular tool steel.
Coolant Hole
Sigma has designed a special adjustable coolant system which can be set very easily on insert cutting points and being special nozzle system it gives high pressure to the flow of coolant which helps fast cutting and easy flow of chips.
Cartridge
Sigma customized cartridges are compact and robust in design and also they sustain heavy cutting forces.
Balancing
Balancing of rotary tools plays a very important role in its performance. Boring bars at sigma are dynamically balanced as per the service RPM. It also helps in increasing the life of machine spindle and accuracy of the bore.
Class of Taper
Holding system requires high precision with fine grinding. We at sigma maintain CLASS of TAPER as per ISO Class AT2.
Coating
Coating of customized boring bars is an important aspect. We have a unique coating setup which prevents the wear and tear of the tools and also increases its life by 35%.
