New Honing Process Produces High-Precision in Manufacturing

Single Stroke Honing from Sunnen is a single-pass process that sizes and finishes a bore with a series of progressively larger superabrasive tools adjusted to a pre-set diameter. Single Stroke Honing tools rotate while passing through the bore one time and then withdrawing. The machine's servo-controlled stroking system provides flexibility with adjustable speed and various feed profiles, such as pecking, short stroke, dwell, etc. Column feed and spindle speed can be varied throughout a cycle using the machine control. 
Developed in Europe by Sunnen Products Company, the Single Stroke Honing® process for cast-iron hydraulic valve bodies produces less than 2 µm cylindricity in bores, achieving almost 200 percent more precision than previously possible.

Ultra-Precise Double-Disc Grinding Machines

Fast grinding disc changes are possible through easy accessibility and a precise change unit on the Thielenhaus-Nissei double-sided grinding machine.
This cost-efficient, compact double-disc grinding machine from Thielenhaus-Nissei is ideal for large-scale production of flat precision parts.

Space-Saving Grinder Automation

Because of its size, the new wheel changer does not increase a machine’s footprint, so shops can add the automation while conserving valuable factory floor space. The wheel changer accommodates up to six grinding wheel sets or electrodes with maximum diameters of 150 mm. It also features a newly developed belt-driven spindle that increases the grinding/eroding length by up to 40 mm over the maximum length of a conventional Mini Power with its two spindle ends.
A a new compact wheel changer from United Grinding provides more set up and part processing flexibility and boosts overall output through continuous uninterrupted machine operation on Walter Helitronic Mini Power grinding machines and Helitronic Diamond Evolution two-in-one eroding and grinding systems.
