Upgraded Vertical Honing Machines
June 1, 2013
Sunnen Products has introduced new servomotor and drive technology for its three primary vertical honing platforms. The company's existing SV-1000, SV-400 and SV-500 models are being replaced with the SV-2000, SV-2400 and SV-2500 series of machines.
The new models have upgraded capabilities such as selectable tool feed, constant crosshatch and faster automatic bore detection for reduced cycle times. The machines can process bore IDs from 3 mm to 300 mm, typically found in parts such as fuel injectors, piston pumps, engine/compressor cylinders, diesel cylinder liners, landing gear and similar components.
The new models now include a 7.5 kW (10 HP) servo spindle. The SV-2000 platform offers a choice of controlled-force or controlled-rate tool feed. Controlled-rate allows automatic tool feed in increments as fine as 0.1 µm (0.000010"). Controlled-force tool feed monitors force in the tool feed system. It feeds the abrasive at the highest rate possible for part conditions for shorter cycle times and longer abrasive life.
The SV-2400 platform now includes selectable constant spindle load and controlled-rate tool feed as standard.
Other new capabilities on the upgraded models include whole-bore, constant crosshatch angle. Constant crosshatch eliminates the flattening of the crosshatch angle at stroke-reversal points, a feature required by some engine manufacturers and MilSpec parts. The new drive technology also enables the machines to be set up to hone only on the pull stroke or produce custom profiled and tapered bores.
All the new platforms include safe-drive technology that monitors all safety devices on the machine with a separate PLC, which stops or limits the speed of the drives if triggered.
