Vertical Rotary Table Surface Grinder: Full‑process Record of Saw Blade Grinding from Rough Grinding to Mirror Finish

Saw blade machining demands extremely high grinding efficiency and flatness. Conventional processing methods usually involve multiple procedures including rough grinding, fine grinding and polishing, which require repeated re‑clamping across different machines. Such workflow suffers from low efficiency and unstable precision.

The vertical‑spindle rotary‑table surface grinder from Shandong Linmo is equipped with a heavy‑duty circular electromagnetic chuck on the worktable. Supported by advanced silicon‑controlled magnetizing and demagnetizing technology, it delivers powerful and easily adjustable holding force. Multiple saw blades can be clamped in a single setup for simultaneous grinding, enabling full‑process operations from rough grinding to finish grinding on one single machine.

For actual saw‑blade grinding, the machine adopts wheel‑face grinding. Combined with workpiece rotation of the circular electromagnetic worktable and cross‑ram reciprocating motion, the three elements generate a composite “rotation + reciprocation” machining path, which greatly cuts grinding cycle time.

Model MP7450 vertical‑spindle rotary‑table surface grinder is specially developed for saw‑blade grinding. It can process rough saw‑blade blanks up to mirror‑like surface finish, fully demonstrating the machine’s strengths of high efficiency and high accuracy.

In real‑world industrial applications, Shandong Linmo vertical‑spindle rotary‑table surface grinders reliably process fundamental components such as bearings, valve plates and saw blades. They are also well‑suited for hard‑and‑brittle materials including ceramics and quartz.

Capable of completing full‑range processing from rough grinding to mirror‑finish within one machine unit, it effectively reduces equipment investment for saw‑blade manufacturers. Meanwhile, it improves batch consistency and overall product quality, bringing tangible economic benefits to saw‑blade producers.
