Sunnen Products Co.
Sunnen Products Company, a global leader in high-precision honing, bore sizing, and engine rebuilding equipment, announces that it will be highlighting its advanced honing technology for the firearms industry at The NSSF SHOT Show, January 20–23, 2026, at the Venetian Expo + Caesars Forum in Las Vegas, NV. The company will be showcasing its HTE-1600W Tube Hone at booth 533318, demonstrating its capabilities specifically tailored for the firearms and defense market.
The HTE-1600W represents the pinnacle of Sunnen's honing technology, designed to meet the exacting demands of firearm barrel manufacturing. This advanced machine can hone gun barrels with internal diameters ranging from 4 to 20mm (.15 – 0.79") and lengths up to 1,500mm (59"), making it suitable for a wide variety of firearm types.
One of the key features of the HTE-1600W is its all-electric design, ensuring consistent performance and easy maintenance, critical in precision firearm manufacturing. The machine’s 100% process control with tool overload protection prevents tool breakage and maintains high-quality standards for firearm barrels.
The HTE-1600W’s active 3-axis function control, which provides superior bore geometry and high accuracy, is essential for improving firearm performance and consistency. It also offers variable stroke speeds, allowing for precise control and optimization of the honing process for different firearm barrel materials and designs.
Efficiency is at the forefront of the HTE-1600W’s design. Its temperature-compensated spindle ensures constant performance without warm-up time, increasing throughput in firearm manufacturing. The Windows-based touchscreen control enables easy storage of tool-specific settings for different firearm models and calibers, with the ability to save up to 999 setups.
Safety and precision are paramount in firearm production, and the HTE-1600W addresses these with its optional safety system and unique feed control system. The latter automatically corrects tight sections in gun barrels, ensuring uniform bore diameter. Additionally, the machine’s traveling steady rest provides crucial support for tooling used with long barrels, maintaining precision throughout the honing process.
Visitors to booth 533318 at SHOT Show 2026 will have the opportunity to speak with the company's experts and learn about how the HTE-1600W can elevate precision firearm manufacturing.
