📌 Purpose:

Quick Change Tap Adaptors for Tapping and Thread Forming

Quick Change Tap Adaptors are designed to significantly reduce tool changeover time. They enable rapid insertion and removal from the tapping attachment, ensuring minimal machine downtime. The adaptors provide reliable tap alignment and secure locking through a square drive system. Each tap shank size requires a specifically matched adaptor to ensure optimal performance and accurate thread cutting or forming.

🏗️ Machine Compatibility:

Model TCNR Tapping Attachment can be seamlessly mounted on:

v  TACO Products – HRF, TCNF

v  Centre lathes

v  Capstans and turret lathes

v  Semi-automatic machines

v  Drilling machines and Milling machines

v  Radial drilling machines

Engineered for reliability, speed, and precision in high-performance tapping operations.

🔑 Key Advantages:

v  Universal Machine Fit: Universal Machine Compatibility Designed for maximum adaptability; this adaptor fits Reversible Tapping Attachment and Non-reversible Tapping Attachment. It's also fully compatible with Tap Chuck and Pneumatic Tapping Machine, as well as CNC and VMC machines, making it a go-to solution across conventional and automated setups.

v  Tap Compatibility: Accepts IS standard HSS tap sets.

v  Material Suitability: Optimized for ductile metals like MS, CI Casting, Low Carbon Steel, Aluminium and Copper, and also suitable for Steel.

v  Cost-Efficient Tapping: Enables fast multi-size tapping at low cost with a single attachment.

v  User Requirement: For best performance, operation by a semi-skilled machinist is recommended.

v  High-Speed Output with QA Adaptors: QA Adaptors, when used with HRF and TCNF models, enable significantly faster tapping cycles compared to conventional TCN and HR models. Their quick-change mechanism supports rapid tool exchange, making them ideal for high-speed, multi-size tapping operations. This setup not only enhances productivity but also offers a cost-effective solution for batch and mass production environments.

v  Die Holder Model DH – Versatile Threading Solution: The Die Holder Model DH transforms a standard tapping attachment into a high-efficiency threading tool with a simple die-holder insertion.

🎯 High-Precision Features:

v  Improved Thread Quality: Gauge-Perfect Thread Quality Consistent thread geometry is ensured through precision alignment and optimal cutting dynamics achieving top-tier thread quality with every pass.

v  Production-Ready: Capable of handling both batch quantities and mass production with ease.

v  Amazing Tap-Changing Efficiency: The HRF/TCNF model features a smartly engineered Quick Change Tap Adaptor (QA) system that allows rapid and effortless tap replacement. This not only minimizes downtime but also enhances operational efficiency perfect for fast-paced production environments where time truly is money.

📐 Technical Operating Range:

v  Threading Speed: 300–1000 RPM depending on material and tap condition (Always use coolant for finish-grade threads and longer tap life.)

v  Material Hardness: 50–60.5 HRA, 81–97 HRB, 0–20 HRC, [ Rockwell ]

v  Max. Tapping Depth: Up to 3× to 4× the tap diameter. [ Length × Diameter ]

📝 Note: The given Torques include a wear factor of 100% for material having a tensile strength ≤B 1000 N/mm = 145,000 Lbs/sq. in. with respect to dia. of pre-drilled holes, cutting fluid, centering of tap etc. When tapping non-ferrous material such as aluminium alloys and brass, the torques can be considerably less than shown in the tables. This rulling is also valid when taping fine-pitch threads. On the other hand, when tapping tougher materials, the torques may be increased by the 50%value and in cold forming threads, the torques may be increased by 40 to 100% value stated in the table.

 

The provided abbreviations refer to different thread standards. AI stands for ANSI Inch, AM for ANSI Metric, UF for UNC/UNF ISO Full, UR for UNC/UNF ISO Rel (where "Rel" likely means related), BF for BSW ISO Full, BR for BSW ISO Rel, J for JIS (Japanese Industrial Standard), and D for DIN (Deutsches Institut für Normung - German Institute for Standardization). These abbreviations are used to specify the type and standard of a screw thread. 

v  AI (ANSI Inch): Refers to the Unified Thread Standard (UTS) as defined by the American National Standards Institute (ANSI). This includes UNC (Unified National Coarse) and UNF (Unified National Fine) threads. 

v  AM (ANSI Metric): Refers to the metric screw threads defined by ANSI, based on the ISO metric thread standard. 

v  UF (UNC/UNF ISO Full): Likely refers to Unified National Coarse (UNC) and Unified National Fine (UNF) threads, where the "Full" indicates a standard thread form as defined by the ISO (International Organization for Standardization). 

v  UR (UNC/UNF ISO Rel): Similar to UF, but the "Rel" might indicate a related or modified version of the UNC/UNF thread form, possibly with slightly different tolerances or minor variations from the full ISO standard. 

v  BF (BSW ISO Full): Refers to British Standard Whitworth (BSW) threads, a very old British thread standard, where "Full" likely indicates the standard thread form as defined by ISO. 

v  BR (BSW ISO Rel): Similar to BF, but the "Rel" might indicate a related or modified version of the BSW thread form, perhaps with minor deviations from the full ISO standard. 

v  J (JIS): Refers to the Japanese Industrial Standard for screw threads. 

v  D (DIN): Refers to the German Institute for Standardization (Deutsches Institut für Normung) standard for screw threads. DIN standards are widely used in Germany and other parts of Europe. DIN 931, DIN 933, DIN 934, and DIN 970 are common DIN standards for bolts and nuts.  

v  IS : While "IS" itself might refer to "Indian Standard", in the context of threads it's often used as a shorthand for ISO (International Organization for Standardization) threads, which are a globally recognized standard for metric threads. 

v  BSW : British Standard Whitworth, an older British standard for screw threads. It was the first national screw thread standard. 

v  UNC : Unified National Coarse, a thread standard within the Unified Thread Standard (UTS) primarily used in North America. 

v  UNF : Unified National Fine, another thread standard within the UTS, characterized by a finer pitch than UNC.

🔩 Tap Adaptor QA – Quick Smart Summary

🔑 Key Features

v  QA Style Tap Adapters: Designed for DIN shank taps with metric threading.

v  Size Range: Covers M1 to M33 taps across QA 0 to QA 3 models.

v  Precision Dimensions: Each adapter includes detailed specs like diameters (D, D1, D2) and lengths (L1, L3, L4, L5).

v  Multiple Styles Available: Includes QA, QASB, and QRE styles for varied chuck compatibility.

⚙️ Operating Highlights

v  Quick Change Mechanism: Tap insertion and ejection via push-fit and knurled sleeve for fast tool swaps.
