SDV Anti-Vibration Tools for Lathes - China Suppliers & Factory - High Performance ISO Insert Turning Bodies

The SDV anti-vibration turning tool system is a modular boring and turning tool solution designed to suppress vibration during deep-hole machining operations. It uses a specially engineered tool holder body with internal damping mechanisms combined with interchangeable cutting head cartridges. By absorbing and dampening the vibration energy generated during cutting, the system enables stable machining at L/D ratios of up to 10×, delivering superior surface finish and extended tool life.

The SDV series offers a comprehensive range of interchangeable anti-vibration turning tool heads to suit different machining applications, including: MCLNR/L, MDUNR/L, MVUNR/L, SCLCR/L, SDUCR/L, SVUCR/L, SVLCR/L, SDPCR/L, SVZCR/L, MDZNR/L, MDPNR/L, and MVZNR/L. Each head type is compatible with specific insert geometries and is available in multiple shank diameter sizes ranging from Ø16 mm to Ø80 mm.

The recommended clamping length should not be less than 4× the L/D ratio of the holder. It is strongly advised to use a clamping cover with an opening (split-sleeve) method or equivalent holding clamping methods for best rigidity. Screw clamping methods should be avoided as they may compromise the anti-vibration performance. When performing long-duration machining operations, internal coolant supply is recommended to maintain cutting performance and tool life.

An exclusive Centre Calibration Block (SDVXZ series) must be used when assembling the cutting head cartridge onto the shank for the first time. Two sizes are available: SDVXZ16-25 for SDV16/SDV20/SDV25 holders, and SDVXZ32-60 for SDV32/SDV40/SDV50/SDV60 holders. This calibration tool ensures the cutting edge is precisely set to the correct centre height, which is critical for achieving accurate dimensions and preventing premature insert wear.

Yes. SDV50 and SDV60 diameter holders are designed to accept smaller-diameter cutting heads via a Reducing Head adapter. For example, the SDV50-C50-518 uses the RH-SDV50-SDV32 reducing head to mount SDV32 cutting heads, while the SDV60-C60-628 uses the RH-SDV60-SDV40 reducing head to mount SDV40 cutting heads. This modular design provides greater flexibility and reduces tooling inventory costs.

Before assembly, all mating surfaces must be thoroughly cleaned and wiped free of any chips, oil residue, or contaminants. The critical areas to clean include: the V-shaped geometric slot on the cutting head cartridge and the shank, the connecting end of the shank that interfaces with the adaptor, and the internal bore of the clamping holder. Proper cleaning of these surfaces (referred to as positions A and B) is essential to ensure accurate seating, maximum rigidity, and optimal anti-vibration performance during operation.
