Product Uses
1.The Internal grooving tool delivers precise groove width control with tight positional tolerance, ensuring consistent slot geometry across production batches for sealing ring and retaining ring grooves.
2.The Micro grooving bar features optimized chipbreaker geometry that ensures effective chip splitting and evacuation, preventing chip packing in deep narrow slots and ensuring smooth continuous machining.
