"Sunnen's HTG Series tube hones are designed as oilfield workhorses with high-volume throughput and increased part capacity," said a company spokesperson. The standard HTG Series is capable of handling standard part lengths up to 44.7' (13.6 m) and weights up to 17,600 lbs. (8,000 kg). The HTG's I.D. range is 2 to 24' (50.8 to 609.6 mm), double that of previous generation machines, with an O.D. capacity of 26' (660.4 mm) standard, and up to 48' (1219.2 mm) as an option.
"The machine is ideal for down hole equipment applications, such as drilling jars, pumps/motors and hangers, and large hydraulic cylinders such as those found on offshore oil platform stabilizers," said the spokesperson. "A new proportional load control hydraulic system enables maximum utilization of hydraulic power, delivering power where needed during operation for maximum efficiency. The system can deliver up to 40 HP (29.83 kW) to the spindle and up to 18 HP (13.42 kW) to the tool stroking system, for metal removal rates of 200+ in3/hr (3,500 cm3/hr) using superabrasives in steel.
"For increased speed and accuracy, the HTG uses a new precision hydraulic feed system that combines the brute force of hydraulics with the finesse of a sophisticated control. This includes servo position control of the feed system actuator, electronic pressure control and closed loop feedback. The machine features a 100-foot/min (30.48 m/min) maximum stroke velocity, 0-300 RPM spindle, and a tool feed force of up to 2,500 lbs. (11,200 N). The new servo system on the feed axis provides increased accuracy, as well as improved maintenance, service and set-ups with no tuning required."
The HTG is available in six standard model sizes with stroke lengths of 4, 6, 8, 10, 12 and 13.75 m (13.12, 19.7, 26.5, 32.8 39.4 and 45.1'). Custom lengths and base designs are also available.
"To save floor space, the HTG's electrical panel is mounted with the hydraulic power unit designed for ease of maintenance with accessible components, an easy-to-clean tank, cleanable air filters on the oil heat exchanger, and oil temperature/level indicators on the machine and control," said the spokesperson. "A new work base has an improved design sloped to the center of the machine for removal of honing 'mud,' and it includes standard full-time coolant flush. This means operators spend less time shoveling out the base of the machine during high-production runs.
"The HTG features a new Siemens PLC touchscreen control system with zero shutoff, feed pressure control, cross hatch angle calculator and a joystick to allow the operator to move the honing tool over the stroke length. The new control system features complex software to maximize process efficiency in the background while providing intuitive touchscreen operation. The power of the hydraulic system is controlled with precision, enabling better control for tough parts such as blind bores and shoulders. A load meter enables detection of tight bore conditions, and the bore profile is included on the display. Other features designed to increase productivity include feed system soft start, and integral load meter and recommended settings based on part dimensions and material."
The standard chain vise fixture is designed for ease of movement on the machine rails for locating during set-ups, as well as improved ergonomics and adjustments.
Sunnen develops tube honing systems with seven models with I.D. ranges from .2" (4 mm) to 39" (1,000 mm), stroke lengths from 39" (1 m) to 46' (14 m), and spindle power from 1.5 HP (1.1 kW) to 40 HP (30 kW).
