Honing Machine handles prototype to production volumes.

October 15, 2014

Merging Siemens 9 in. touchscreen PLC and digital-servo drives with servo-hybrid tool feed system, Model SH-4000 is engineered for medium to high production of parts with bore diameters from 0.060–6.50 in. Horizontal honing machine features 5 hp spindle drive and 1.5 hp stroker drive with 15.75 in. stroke length for deep bores. Spindle speed is infinitely adjustable from 200–3,000 rpm with stroke rates of 10–550 spm. In addition, cutting pressure can be adjusted in 1 lbf increments to 500 lbf. Read More

All-Electric Tube Hone handles bore ID's up to 35.41 in.

September 22, 2014

Combining servo precision and cycle-automation features with 0.004 in. stroke repeatability, Model HTR can hone blind bores or correct tight spots in bore without operator intervention. Modular design can be configured for stroke lengths from 8–46.2 ft. Machine's 12 kW spindle motor, combined with 4-step gearbox, produces constant power band through entire speed range of 10–470 rpm for fast metal removal. To manage all functions, machine includes 12 in. Windows® touchscreen control. Read More

Aluminum-Oxide Honing Stones provide heavy stock removal.

August 5, 2014

Available for Sunnen General Hone tools as well as those of other manufacturers, 60-grit Premium Red Aluminum Oxide Abrasive resists chip loading and galling, even in stainless steel. Product is specifically formulated for machining oil/gas industry parts where fast, base-metal removal is critical to enlarging bore in short cycle time. Abrasive offers alternative for shops where inexperienced machine operators might damage faster-cutting, but higher cost superabrasives.

Precision Small Diameter Honing System handles small-bore parts.

May 22, 2014

Able to produce smooth, round bores as small as 0.160 in. dia, HTE tube hone handles parts up to 60 in. long and has ID range of 0.160–0.750 in. One-piece base maintains optimal tool/part alignment, and sensitive feed system feature maximizes protection against tool overloading. Tool-specific force limits and run settings are stored in Windows®-based touchscreen control, and feed system senses tight sections in part and corrects them automatically. Three fixturing options are available. Read More

Honing Machines utilize single-pass process.

April 24, 2014

Available in 3 models with up to 6 spindles, VSS-2 Series provides precision sizing of bores from 0.149–2.0 in. dia in stamped parts, hydraulic valve bodies, gears and sprockets, parking pawls, and rocker arms. Spindle carriage provides 28.5 in. stroke and up to 250 ipm stroking speed. Using series of progressively larger superabrasive tools adjusted to pre-set diameter, High-Precision Single Stroke Honing® process produces <2 micron cylindricity in bores up to 10x longer than diameter.

Front-Loading Large-Part Honing Machine handles job shop volumes.

July 25, 2013

With 760 mm X-axis, 1,500 lb weight capacity, and 508 mm stroke length, SV-20 offers true linear, vertical, servo-stroking system to produce precision bore geometries on parts. PLC-controlled machine is equipped with variable-speed (15–550 rpm), 5.5 hp spindle motor capable of driving 2-stage, metal-bond, diamond abrasives. Linear stroking system keeps honing tool concentric with bore throughout full stroke length, producing consistent diameter from top to bottom of bore. Read More

Vertical Honing Machines employ servo technology.

January 11, 2013

Processing bores IDs from 3–300 mm, SV-2000/-2400/-2500 series have 10 hp servo spindle and offer such capabilities as selectable tool-feed, constant crosshatch, and automatic bore detection. Series SV-2000 offers choice of controlled-force or controlled-rate tool feed; latter allows automatic tool feed in increments as fine as 0.1 µm, while former monitors force in tool feed system. Series SV-2400 includes selectable constant spindle load and controlled-rate tool feed as standard. Read More

Vertical Honing Machines offer selectable tool-feed.

January 10, 2013

With updated servomotor and drive technology, Models SV-1000, SV-400, and SV-500 models are being replaced with Models SV-2000, SV-2400, and SV-2500. Range of machines can process bore IDs from 3–300 mm, typically found in parts such as fuel injectors, piston pumps, gun barrels, and hydraulic components. Upgraded models feature 7.5 kW/10 hp servo spindle, constant crosshatch angle, automatic bore detection, and safe-drive technology, which monitors safety devices on machine with separate PLC.
