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.

Tool Grinder Handles Complex Cutting Tools

The U Grind has a NUM Fleximum control with the latest generation of NUMROTOplus tool grinding software for all types of cutting tools, including complex step/form tools, hobs, burs, shape cutters, T-slot cutters, high performance endmills and drills, routers, form tools, porting tools and more.
The flexible, high-accuracy U-Grind 5-axis CNC tool grinder from Strausak is ideal for small batch production, regrinding, and high-precision tool grinding.

High Accuracy Cylindrical Grinding for An Affordable Price

For precision, efficiency and productivity, the wheelhead features a highly rigid main body, a heat-treated nitride steel wheel spindle and a large ø 510 mm wheel. To maximize stability and load capacity, the wheelhead and table feed include wide, V-flat guiding surfaces. The high damping performance and equalization of lubricant provided by the oil film’s squeezing effect ensure long-term smooth and precise grinding. Non-concentric hydrodynamic bearings secure an optimal wedge angle. Bearings are ground to a high degree of precision with an exclusively developed grinder for bearings.
GAE Series CNC Angular Cylindrical Grinders from Shigiya are ideal for heavy grinding precision and, when combined with an angle head type wheelhead, perform face grinding with ease.

Angle Grinders Maximize Material Removal

The key features in the 1660 and 2260 angle grinders include dual auxiliary handle positions, reversible throttle handle and interchangeable guards that allow for versatility to fit any application.
The 1660 and 2260 Angle Grinders from Cleco Tools have a streamlined angle head and all metal housing for ultimate ruggedness that minimizes shop downtime, enhances productivity and increases the bottom line.
