NC Tool Holder Series VDI DIN 69880: Versatile Solutions for CNC Lathe Turrets​
The NC Tool Holder Series VDI DIN 69880 represents a comprehensive range of precision-engineered tool holders designed to elevate the performance of CNC lathe turrets. Encompassing models B1, B2, C1, C2 and compatible with VDI30, 40, 50 specifications, this series combines strict adherence to international standards with versatile features, making it an indispensable asset for diverse machining applications—from general engineering to high-precision aerospace manufacturing.​
At the heart of this series is its compliance with the DIN 69880 standard, ensuring uniform dimensions, functionality, and compatibility across all variants. This standardization allows seamless integration with VDI turrets of corresponding sizes (VDI30, 40, 50), eliminating compatibility hurdles and reducing setup time for manufacturers. Whether equipping a small CNC lathe or a large-scale production center, the series guarantees consistent performance, a critical factor for maintaining efficiency in both low-volume custom work and high-volume mass production.​
Precision is a hallmark of the NC Tool Holder Series, starting with the cylindrical shank machined to IT6 (h6) tolerance. This exacting standard ensures a tight, secure fit within the turret, minimizing radial play and enhancing stability during high-speed rotation. Reduced vibration not only improves surface finish quality but also protects both the tool and workpiece from potential damage, especially when machining materials with strict tolerance requirements, such as medical components or automotive precision parts.​
Durability is engineered into every tool holder through full case hardening. This process creates a hardened outer layer (58 ± 2 HRC surface hardness) for exceptional wear resistance, while retaining a tough core with strength exceeding 1000 N/mm² to absorb mechanical stresses. This balance makes the holders resilient against the rigors of heavy cutting operations, prolonging service life and reducing replacement frequency—a cost-saving advantage for busy production facilities.​
Key components, including the shaft, serration, seating face, locating bore, clamp plate, and locator bore, undergo precision grinding. This meticulous process ensures flatness, parallelism, and dimensional accuracy, critical for maintaining consistent tool positioning. The result is repeatable performance across multiple setups, ensuring uniform part quality in batch production and reducing the need for frequent recalibration.​
Versatility is enhanced by adjustable features tailored to diverse machining needs. Each holder can be quickly adjusted to the next lower cutter height, adapting to changing workpiece requirements without specialized tools. Additionally, two stop screws allow fine-tuning of the cutter’s position, enabling precise control over cutting depths and heights—essential for operations like facing, grooving, or threading. This adaptability makes the series suitable for both simple and complex machining tasks, eliminating the need for multiple dedicated holders.​
The clamping mechanism features spring-mounted pressure plates that secure the cutter with consistent force, preventing slippage even under high torque or vibration. This reliable grip enhances cutting stability, extends tool life by minimizing premature wear, and reduces the risk of costly errors during machining.​
Efficient coolant delivery is achieved through internal ball nozzles, which can be quickly adjusted using a new clamp fixture. Optimal coolant flow to the cutting zone reduces heat buildup, flushes away chips, and extends tool life—particularly valuable in high-speed machining or when working with heat-sensitive materials like titanium or Inconel.​
As specified by DIN 69880, each holder includes an undercut at the shank sealing face to accommodate an optional sealing ring. This feature prevents coolant leakage, protects turret internals from contamination, and enhances overall system reliability, reducing maintenance downtime.​
In summary, the NC Tool Holder Series VDI DIN 69880—encompassing B1, B2, C1, C2 models and VDI30, 40, 50 type —delivers precision, durability, and versatility for modern CNC lathes. Its adherence to standards, robust construction, and adaptable design make it a trusted choice for manufacturers seeking consistent performance, reduced downtime, and high-quality results across diverse industrial applications.
