Sunnen Products Co.’s entry-level HTA Tube Hone machine offers advanced features that improve performance, efficiency and precision in bore finishing for various industries. The HTA Tube Hone is well-suited for hydraulic cylinder repair applications.
The all-electric design of the HTA Tube Hone provides quieter operation, eliminates oil leaks and offers better control and greater accuracy during bore reversals. This lean design also features a smaller footprint compared to traditional horizontal tube honing systems.
At the core of the HTA Tube Hone is an electromagnetic Siemens Servo Stroker Motor with Belt Drive, providing quiet and precise operation. The 3-hp (2.24-kW) spindle unit, paired with a servo stroker capable of speeds from 5-90 ft/min (1.5-27.4 m/min), supplies ample power for resurfacing and repairing applications at spindle speeds of 20-300 rpm.
The machine includes a programmable auto tool feed system, enhancing efficiency and consistency in the honing process. 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.
Ergonomics and safety are key aspects of the HTA Tube Hone’s design, reducing the risk of injury by minimizing manual work with repetitive motions. The Siemens PLC with a color touch screen controls all machine functions, such as stroke reversal, speeds and a cross hatch calculation. The stroker joystick enables 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 in tight spaces.
The HTA Tube Hone offers flexibility with a swiveling operator station. Multiple language options and metric/inch conversion are selectable from the touch screen.
Additional features include a load meter for quickly identifying tight spots in the bore, a universal V-block work holding system for flexible and quick fixturing of various workpieces and an integral work tray that combines with the enclosure and operator console for a clean and efficient workspace.
The HTA Tube Hone is compatible with ANR-275 tooling, enabling shops already using ANR-style tooling to utilize existing stone supports, master holders and abrasives.
