New Honing System for Hydraulic Actuators is First All-Electric Design - Richly Featured, Lean in Cost

Ideal for cylinder resurfacing, the HTA actuator hone is PLC controlled, handles parts up to 12 feet long, 21 inches diameter and 4000 pounds.

February 2009 - The new HTA actuator hone introduces the first all-electric, lean design, engineered specifically for hydraulic service facilities doing resurfacing and repair of actuators for construction, mining, farming and forestry equipment. The machine is available for 6-foot (2 m) and 12-foot (4 m) part lengths, with bore ID of 2.5 to 21 inches (63.5 - 533 mm) and maximum part OD of 24 inches (610 mm), and part weights to 4000 pounds (1818 kg). It includes high-end features, such as Siemens drives and PLC-control with touch-screen HMI for setting all machine parameters, including stroke reversal point, spindle/stroking speeds, and crosshatch angle calculation. The control features a load meter to determine areas of bore tightness, with capability for dwelling the tool in multiple areas to correct part geometry. Other advanced capabilities include automatic tool tensioning, set through the PLC.

The HTA actuator hone is ideal for resurfacing and repair work where light-duty stock removal up to 0.030 inches (0.76 mm) is needed to oversize deeply scratched actuator bores. It is designed for optimum performance with Sunnen ANR275 tooling and abrasives, sold with matching coolants and gauging as part of the machine package. An electronically controlled, 3-hp (2.24 kW), AC gear motor powers the spindle at 0-300 rpm, while the servo-driven stroking system has a speed range of 0 90 ft/min (27.4 m/min). The all-electric machine eliminates the noise, leaks, valve adjustments and performance variability inherent to hydraulic systems.

Also suitable for reconditioning of die casting shot tubes, plastics extruder barrels and flow-tube weld cleanup, the HTA hone is ergonomically designed with a moveable operator station and a modular work holding system for rapid setups. It includes a 48-gallon (182 L) coolant reservoir and paper-media coolant filtration unit. Set on casters for easy maintenance, the coolant tank tucks under the machine frame to conserve floor space.

Sunnen is the world leader in the development of tube honing systems, with more than seven different model sizes in production, ranging up to a maximum 25 feet (7.62 m) in stroke length and 40-hp (30 kW) spindle power.
