SH-4000 digital, servo-stroke honing machine from Sunnen
From its styling and touchscreen HMI to its digital repeatability, Sunnen says that the SH-4000 is barely recognisable as the successor to a line of general-purpose honing machines that boasts 2,400 units across the world.
This next-generation of power-stroked honing machines merges a Siemens touchscreen PLC and digital-servo drives with a patent-pending servo-hybrid tool feed system.
The machine is engineered for medium to high production of parts with bore diameters from 1.5 to 102 mm. It features a 4.1 kW spindle drive, 1.1 kW stroke drive and 400 mm stroke length. Spindle speed is infinitely adjustable from 200 to 3,000 rpm, with stroke rates of 10 to 550 SPM. Cutting pressure can be adjusted in 4.5 N increments to a maximum of 2,224 N.
With 45% fewer parts and greater reliability than its mechanical predecessors, the SH-4000 introduces patent-pending digital-servo tool feed and cutting pressure control, says the company.
