RBH Indexable Twin-bit Rough Boring Heads
RBH Indexable Twin-bit Rough Boring Heads are specialized tools designed for rough boring operations in large diameter applications. These heads feature twin cutting inserts for balanced cutting forces and enhanced productivity in heavy roughing cuts. Key Features: • Twin-bit Design: Two cutting inserts for balanced cutting forces and reduced vibration • Indexable Inserts: Quick insert changes without removing the head from machine • Multiple Boring Ranges: From 25mm to 204mm diameter capacity • Two Insert Types: C-type (CC series - 80° diamond) and T-type (TC series - triangular) • LBK Locking Blocks: Secure insert clamping systems (LBK2-LBK6, BST series) • Various Shank Diameters: From 24mm to 130mm for different applications • High Rigidity: Robust construction for stable boring operations Model Nomenclature: • **RBH**: Product series (Rough Boring Head) • **25-35**: Boring diameter range (25mm min to 35mm max) • **LA**: Insert locking mechanism/head design type • **C/T**: Insert type designation - **C**: Uses CC-series inserts (CCMT/CCGT style - 80° diamond inserts) - **T**: Uses TC-series inserts (TCMT/TCGT style - triangular inserts) Insert Types: • **C-Type (CC Series)**: 80° diamond shaped inserts for general boring operations • **T-Type (TC Series)**: Triangular inserts for specific boring applications Applications: • Large diameter rough boring operations • Heavy material removal in boring • Pre-machining before finish boring • Cast iron and steel boring • Production machining with high metal removal rates • Automotive and aerospace component manufacturing
