Armstrong Introduces the VariSharp CNC band saw sharpener
Armstrongs VariSharp CNC band saw sharpener features a two-axis CNC system to grind virtually all band saw tooth patterns used by sawmills today. Touchscreen control, industrial-grade Pentium computer, and brushless servo-driven ball screws replace the two-cam system previously used. With VariSharp, it's possible to sharpen saws you are using today, while you design those you will use tomorrow.
Grinding parameters, including on/off the face, gullet depth, and number of grinding passes can be controlled by operator inputs on the touchscreen or manually as on a standard No. 4 sharpener. Grinding wheel rpm and teeth per minute are also touchscreen controlled. A powerful 2-hp grinding wheel motor and variable frequency drive provide optimum grinding performance.
The on-board Armstrong tooth library includes over 300 standard, variable pitch (VP) and variable pitch and depth (VPD) tooth patterns available on the touchscreen. Operators can view, modify, and save a single tooth, or a VP/VPD pattern with up to ten teeth in the segment. The tooth library will hold an unlimited number of tooth patterns. When ordering saws, saved patterns can be supplied from the library to the saw manufacturer for use in producing the exact tooth pattern.
Machine specifications for a VariSharp are the same as for a conventional No. 4 Armstrong band saw sharpener. All No. 4 sharpener options are available for the VariSharp. Sidewinder feed finger, StrongArm power gate, and ShapeUp grinding wheel dressing system are required.
