Sunnen's new SV-410 automated CNC honing system gives performance builders and production rebuilders a new level of control for achieving precise cylinder geometry, surface finish and crosshatch parameters for superior ring seal, uniform lubrication, minimal leak down and highest horsepower. Ideal for high-nickel and CGI blocks, the automated, high-horsepower honing system allows engine builders to deliver customized results quickly, with automated efficiency, for consistent quality, highest performance, and longest engine life. The flexibility of the system allows for in-line 4- and 6-cylinder engines, as well as all V-6/8 blocks.
The SV-410 combines automated operation with a 7.5 kW (10 hp) spindle to drive high-accuracy CBN and diamond tooling for short cycle times and high-quality results with minimal labor. Utilizing two-stage metal-bond diamond tooling, the machine eliminates tool changes and completely finishes the bore surface with a plateaued finish. The fully automated system indexes the tool from bore to bore and (for V-blocks) the servo fixture rolls the block for access to all cylinders, ending with a rollover of the block to dump oil/coolant. The servo fixture adapts to any angle V-block via the setup screen without manual adjustments. A work envelope of 915 mm x 1015 mm (36" x 40") and weight capacity up to 680 kg (1500 lb) combine with convenient front loading for versatility in processing a wide range of in in-line or V-blocks. A 500-pound V-block can be rotated in one second, bank to bank.
An optional tool-guide assembly and variety of bore-diameter gaging systems combine with a servo-controlled X-axis travel of 1143 mm (45") to allow automated honing of multi-bore blocks with high precision. Straightness sensing capability provides a display of the bore profile during the cycle. Combined with a patented, servo stroking system, it allows the SV-410 to auto-dwell in any part of the bore to correct straightness automatically in the shortest cycle time. Crosshatch is controlled and set via the control screen for every ring application. The SV-410 can be used to hone blocks with bore diameters from 19-200 mm (0.75-8.00"), depending on the tool options selected.
Designed from the ground up for automated processing, the SV-410 features full-height/walk-in access doors and stainless steel enclosure preconfigured for use with automated part loading systems, while the CNC control includes a built-in automation interface. Setup is simplified with a multi-axis hand wheel for fine-tuning vertical stroke, tool feed, column position and optional cradle position. The system easily walks the operator through setup.
The PC-based, color, touch-screen control features multi-language capability, pull-down menus, unlimited capacity for job setups, and programmable custom tools. In addition to optional in-process air gaging, a variety of optional post-process air-gage systems can integrate with the control for SPC data collection, as well as automatic compensation of size, taper and straightness. The control allows easy programming of multiple bore positions.
The SV-410 is built on a malleable iron base for rigidity and vibration damping. The machine's servo-controlled, straight-line stroke motion is driven by a servo ballscrew at rates of 1-160 strokes per minute, while a powerful 7.5 kW (10 hp) spindle provides ample torque for fast metal removal with tools outfitted with metal-bond CBN and diamond abrasives or standard aluminum oxide and silicon carbide stones. Oversized, lubed-for-life guide ways for horizontal and vertical axes provide smooth operation and long, maintenance-free life. An optional manual rollover fixture is available for less demanding applications.
The precise control of the SV-410, coupled with Sunnen tooling and abrasives tailored to the job, means a high quality bore for every engine application every time. Whether the job is rebuilding for everyday use, building 4-cylinder tuners, or creating the latest high powered V-8 crate engine, the SV-410 produces optimum cylinder geometry and surface finish. This translates to better ring seating, less blow by, reduced oil consumption, and more power.

Seco Tools has announced the availability of its new CBN 170 grade, the first PCBN grade ever developed specifically for the finish turning of nickel-based super alloys commonly found in aerospace, power generation and automotive components. Designed for both toughness and wear-resistance, CBN 170 works well in materials such as Inconel 718, UDIMET, Waspaloy, MAR M and others. In field tests run using CBN 170, it has increased tool life by 40% and cutting speed by 45% as compared to whisker ceramics.
Designed to satisfy the exacting surface finish, tolerance and length of cut requirements typically found in finishing operations for nickel-based super alloys, CBN 170 incorporates a unique whisker ceramic binder, which enhances tool life and reduces insert indexes. These whiskers of silicon carbide crystals add tensile strength and fracture toughness to the grade.
The new grade can be applied to finish machining of hardened and unhardened nickel-based superalloys from cast, forged, powdered metal or machined from solid source. It can achieve depths of cut up to 0.020” at cutting speeds of 900 – 1300 sfpm. Designed for continuous cutting applications, coolant must be applied to the operation.
To further enhance tool life, Seco recommends the use of its Jetstream tooling, which delivers coolant at high pressures close to the cutting edge, cooling the work area and producing smaller, hard, brittle chips.
