AI Technical Summary
Traditional pipe end cutting machines generate powder splashes during the cutting process, which requires protective covers and dust collectors, taking up a lot of space and costing a lot of money.
The toothless saw adopts passive rotary cutting, which drives the toothless saw to cut by the rotation of the workpiece itself. Combined with limit device and brake device, it can achieve precise control and speed adjustment, avoid powder splashing and reduce equipment cost.
It achieves a low-dust, high-precision cutting process, reducing equipment footprint and production costs, while improving cutting accuracy and stability.
