Sunnen HTE Tube Hone for precision, small-bore parts
New honing system takes aim at long, small-bore parts
One-piece base and ultra-sensitive tool-overload detection system make new HTE tube hone ideal for producing smooth, round bores as small as 0.150” (4 mm) diameter.
July 2014 – Sunnen’s new HTE honing system, the company’s most cost-effective small-diameter hone, produces ideal bore geometry and surface finish, while eliminating problems from bad tool-to-part alignment and excessive feedrates that cause tool breaks and scrap parts. The new tube hone’s one-piece base maintains excellent tool/part alignment, and a special feature of the feed system provides maximum protection against tool overloading. Tool specific force limits and run settings are stored in the Windows-based touch-screen control. A unique feed system senses tight sections in the part and corrects them automatically.
The HTE handles parts up to 60” (1524 mm) long and has an ID range of 0.15 - 0.79” (4-20 mm), making it ideal for improving the finish and performance of safety valves in oil field parts, tubing for nuclear energy fuel rods, raw materials for pharmaceutical stents and gun barrels as small as .17 caliber, among others. “The one-piece base not only improves the machine’s performance, it makes it more affordable,” said Dennis Westhoff, business development manager for Sunnen. “The spindle power is also reduced on the low end, making the machine extremely sensitive to tool overloads in long, narrow bores.”
The HTE’s servo-controlled, variable speed spindle (5-2100 RPM) and stroke motors (1-98 ft/min, 1-30 m/min) produce superior stock removal rates in Inconel, 410 stainless steel, zirconium and titanium alloys. The HTE can utilize a variety of Sunnen tooling types including MMT, LFT-DX and GH tools.
Three fixturing options are available: a manual chuck, a pneumatic chuck, or a V-type chain vise for parts with OD’s up to 6” (150 mm). A travelling steady rest is standard. An optional guide pot automatically guides the honing tool straight into the bore without operator assistance. Standard, non-CE guarding includes easily removable covers for each end of the honed part, while optional CE guarding includes a light curtain and wire mesh enclosure. The Swiss-designed machine is built in the U.S.

Sunnen SV-20: large-part vertical honing for job-shop volume
New large-part honing machine for job-shop volume drives diamond abrasives with a linear vertical stroke for ideal bore geometry
760-mm X-axis, 680-kg weight capacity and 508 mm stroke length offer large-part capacity. Ideal for job shops or repair facilities handling oil/gas components, cylinder liners, motorcycle/ATV engines and automotive/truck blocks.
July 2014 – The Sunnen SV-20 honing system is the first competitively priced large-part machine for job-shop part production with a true linear, vertical, servo-stroking system to produce precision bore geometries on compressors, oilfield components, automotive/truck blocks and similar parts. Ideal for job shops and repair facilities, 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.
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's work envelope of 915 mm x 1015 mm (36" x 40"), front-loading design, and weight capacity up to 680 kg (1500 lb) combine for versatility in processing a wide 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 setup. 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-litre (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 400V/50Hz/3Ph or 460V/60Hz/3Ph 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.
Additional information on the SV-20 vertical honing machine is available from Sunnen Products Company, 7910 Manchester Rd., St. Louis, MO 63143. Tel: 1-800-325-3670; fax: 314-781-2268 or email firstname.lastname@example.org.
Sunnen celebrates its 90-year evolution in honing technology: from Hupmobile to high-tech
Founder Joe Sunnen’s quest to sell his honing inventions started 90 years ago with cross country sales calls made from the back of his "RV," a 1916 Hupmobile. Today, Sunnen technology is used worldwide to make energy exploration equipment, chain saws, aerospace components, gears, fuel injectors, fluid-power components and more. And Joe's Hupmobile still has a place of honor in St. Louis.
ST. LOUIS, Mo – Joseph Sunnen’s entrepreneurial spirit drove him to start a “mobile” business, selling his engine servicing tools out of the back of his Hupmobile truck in 1924. Early success led him to develop and patent his manual cylinder hone for auto garages. Decades later, his basic honing device has been evolved into a highly capable CNC machining process by the company he founded.
St. Louis, Missouri-based Sunnen Products Company is today the world's largest vertically integrated manufacturer of precision honing systems, employing more than 650 people at 11 worldwide facilities and holding dozens of technology patents.
“As we celebrate our ninetieth anniversary, my grandfather would be proud to see that his spirit of innovation lives on in our drive to develop new products and techniques,” said Matthew Sunnen Kreider, company president. “The Hupmobile is still on display at our St. Louis headquarters, and it reminds us not only of where we came from, but also what we can accomplish.”
What's honing all about?
Automotive, marine and air race winners learned in the 1930's their engines got a nice performance boost from precisely sized and finished cylinder bores made with Sunnen hones. Today, pressure for more speed, power and accuracy – with lower noise, emissions and fewer maintenance problems – is leading manufacturers to use Sunnen honing systems for an ever-expanding range of products, in more industries than ever before.
The company's latest generation of automated honing systems provides a unique capability to control hole size with accuracy of ten millionths of an inch (0.000010"/0.25 µm), correct geometric (shape) errors in the bore, and produce a specific surface finish to enhance lubrication and sealing properties. The result is gearboxes and transmissions that run quieter, smoother and longer. Hydraulic systems that are more precise, responsive, efficient and leak-resistant. Chainsaws and weed trimmers that deliver higher power densities with lower emissions. And firearms that are more accurate and easier to clean.
Sunnen controls all R&D, manufacturing, service and support of its products, including specialized abrasives and tooling. This allows development of end-to-end processing systems that are custom designed and single-sourced to ensure they meet customers' required quality and production levels. In addition to its U.S. headquarters, Sunnen has operations in Switzerland, France, Italy, U.K., China, Russia, Brazil, Belgium, the Czech Republic and Poland.
