Sunnen’s SV-1000 series vertical CNC honing machine is designed for manufacturers of outdoor power equipment striving to improve the durability and power output of small two-stroke engines. Using TC superabrasive tools—custom designed for blind, ported cylinder bores—the manual or auto-loaded honing machine produces cylinders with micron-accurate size, geometry and exact surface finish to enhance combustion efficiency, engine durability and power output. TC abrasive tools are suited for cylinders plated with chrome, Nikasil and other hard coatings. Servo tool compensation, coupled with optional automatic post-process air gaging on the machine, delivers high process capability in an automated manufacturing environment.

Designed for part diameters ranging from 0.120" to 2.56" (3 to 65 mm), the modular system is capable of mounting multiple spindles to handle roughing and finishing operations. The basic, single-spindle module is designed for future automation with removable side enclosure panels to facilitate flow-through part processing. The machine is available with a fixed tooling plate or servo rotary table with 12-position rotary air union for fixture control. The machine’s cast-polymer base is said to provide quality vibration damping and structural rigidity.

Fully automated versions of the honing machine can be specified with the servo rotary table or linear part transfer, integrated part handling systems and as many as four spindles. For unmanned cellular processing, the machine can be equipped with integrated post-process air gaging to provide closed-loop control of bore size and geometry, along with downloadable SPC data and feedback control. Post-process air gaging with one to four servo columns can provide size, taper and straightness feedback control. Matched with the company’s TC multi-stone mandrels, the air-gage-equipped machine can automatically control bore size to submicron accuracy.
