The SV-20 honing system, a large part machine for job shop part production, features a linear, vertical servo-stroking system to produce precision bore geometries on compressors, oilfield components, automotive/truck blocks and similar parts.
"The SV-20 is equipped with a variable speed 15 - 550 RPM, 4.1 kW (5.5 HP) spindle motor, powerful enough to drive two-stage, metal-bond diamond abrasives for short cycle times with high accuracy and minimal labor," said a company spokesperson. "The SV-20's linear stroking system keeps the honing tool concentric with the bore throughout the full stroke length to produce a consistent diameter from top to bottom of the bore."
The machine features a work envelope of 915 mm x 1015 mm (36" x 40"), front loading design and weight capacity up to 680 kg (1,500 lbs) for versatility in processing a range of large parts. The SV-20 can be used to hone bores with inside diameters from 19 - 200 mm (0.75 - 8.00").
The PLC-controlled SV-20 utilizes a color touch screen with a toggle switch to jog for fast set-up. The swiveling operator panel can be adjusted for viewing from a variety of positions. A hand wheel on the machine allows left/right positioning of the column on its 760-mm (30") X-axis. The machine comes standard with a 208 liter (55 gallon) internal coolant system equipped with two standard canister filters.
The SV-20's rotary servo tool feed system can be used with two-stage hone heads to complete roughing and finishing without stone changes for faster processing times. The machine is compatible with all of Sunnen's past and current tooling for CK/CV/SV-series machines, including diamond abrasive hone heads and brushes, GHSS single-stage hone heads with CBN or diamond abrasives and brushes, and GHTS hone heads for two-stage honing with CBN or diamond abrasives.
The SV-20 is available with a 400 V/50 Hz/3 Ph or 460 V/60 Hz/3 Ph electrical system. Options include a T-slot base, manual rollover cradle for engine blocks and sump pump to allow connection to an external coolant supply.
