New Generation of Bore Sizing, Finishing Machines

"The new SH-6000 builds on Sunnen's 25-year heritage of high-precision CGM and KGM series KROSSGRINDING machines, delivering precision roundness, straightness, bore size and finish - and with tighter tolerances," said a company spokesperson. "The SH-6000 yields consistent and accurate bore size control tolerances to .00025 mm (.000010") by utilizing diamond plated or metal bonded abrasive tooling for maximum performance."

"The SH-6000 is the result of a four-year development process acquiring global input with all aspects of the CGM and KGM machines analyzed for improvement," said Phil Hanna, Sunnen Product Manager. "It is engineered for jobs requiring ultra-accurate size control, but we also improved operator productivity with a focus on easy set-up and operation, as well as better reliability and simple maintenance."

Designed to allow inexperienced operators to run the machine efficiently and safely, the SH-6000 comes standard with stone wear compensation, feed speed regulation, multi-step feed, spindle reverse, in-process speed change and short stroking, part counter and 13 operator languages. The Siemens PLC interface with a large 225 mm (9") touchscreen stores more than 1,000 setups.

A runout-adjustable spindle with direct CGT tooling connection makes it well suited for quick changeover for medium-to-high volume production operations. The SH-6000 is compatible with Sunnen CGT, CRT, MMT, SRT and TC tooling series.

A 25 mm Bosch Rexroth servo controlled ball screw stroker is designed to provide precise positioning and consistent performance and wide stroker carriage accepts all standard fixtures. Custom fixturing plates can be ordered.

The ergonomic work area comes standard with a rear-mounted, large-capacity electrical enclosure, but can be ordered on the right or left side to easily adapt to floor space limitations. The standard coolant system has a 208L (55 gallon) capacity and is equipped with a PF filter cartridge, magnetic separator, quick disconnect lines and a level gauge.

Both high-speed and high-torque models are available to replace existing CGM/KGM models and for new applications.
