Sunnen Highlights All-Electric HTA Tube Hone for Enhanced Precision and Efficiency in the Energy Industry

Sunnen Products Company, a global leader in high-precision bore finishing and measurement, highlights its innovative entry level HTA Tube Hone machine, setting a new standard in bore finishing for the energy industry. With over 375 sold to date, the HTA Tube Hone represents a significant advancement in honing technology over manual honing, offering a range of features that deliver superior performance, efficiency, safety, ergonomics, and precision perfect for modern energy production environments including gas metering tube finishing, steam turbine rotor refinishing, and numerous other low stock removal applications.

Its all-electric design ensures quieter operation and eliminates oil leaks and heat buildup over hydraulic machines. It also provides better control and greater accuracy during bore reversals, vital for producing precision components used in energy equipment. This lean design boasts a smaller footprint compared to traditional horizontal tube honing systems, saving valuable floor space and capital in OEM, job shop, and repair facilities.

At the heart of the HTA Tube Hone is a Siemens Servo Stroker Motor with steel reinforced Belt Drive, providing quiet and precise operation, ideal for maintaining strict tolerances in rebuilding critical energy sector parts such as pump liners and oil rig hydraulic cylinders. The 3 HP (2.24 kW) spindle unit, combined with a servo stroker capable of speeds from 5 to 90 ft/min (1.5 to 27.4 m/min), delivers ample power for resurfacing and repairing at speeds of 20–300 RPM. 

The HTA Tube Hone features a programmable auto tool feed system, increasing efficiency and consistency. A 55-gallon paper media coolant filtration unit with quick disconnects, casters, sight glass, and manual paper bed filter maintains clean coolant, improving honing performance and extending abrasive life and maintaining surface finish in energy facilities.

Ergonomics and safety are prioritized in the HTA Tube Hone’s design, reducing the risk of injury associated with manual honing that is often used for these components.

Operators benefit from the easy to use Siemens PLC with a color touch screen, which controls all machine functions such as stroke reversal, speeds, and a cross hatch calculation. The stroker joystick allows for precise positioning of the honing tool and stroke length adjustment during setup, while stroke control override enables short-stroking in any part of the bore for clean-up.

The HTA Tube Hone offers flexibility with its swiveling operator station that accommodates space constraints common in energy production environments. Multiple language options and metric/inch conversion are selectable from the touch screen, enhancing ease of use across global energy operations.

Additional energy-focused features include a load meter for quickly identifying tight bore spots in components like gas metering tubes, a universal chain vise work holding system to accommodate a range of part sizes, and an integral work tray for maintaining a clean, organized work area. 

The HTA Tube Hone is compatible with ANR-275 tooling, allowing energy sector machine shops to leverage existing stone supports, master holders, and abrasives, thereby reducing tooling costs.
