Before 2008, band saws were the primary processing equipment in the wood processing industry, using traditional methods. The production efficiency was low, as only one board could be cut at a time. However, log multiple-blade saws equipped with multiple saw blades on the saw shaft could cut an entire log in one pass, significantly increasing production efficiency. They had shorter production cycles, faster delivery times, and larger factory capacities, allowing businesses to quickly grow and expand.

In terms of safety, the transmission and saw band of band saws were completely exposed, making them prone to accidents and injuries. Log multiple-blade rip saws were designed with full enclosures, greatly improving safety performance.

In terms of technical requirements, band saws required workers to possess specialized skills, including precise positioning and tooth setting. Circular multiple-blade saws were customized for production, and ordinary workers could operate them with minimal training, resulting in significantly reduced labor costs.

Log multiple-blade saws used alloy saw blades, operated at high speeds, and produced precise boards (with an error margin of no more than 20 wire thicknesses). The boards had smooth and even surfaces, requiring only direct sanding. On the other hand, band saws relied solely on manual operation, resulting in crooked and rough boards with a fuzzy surface, requiring additional planing processes that were time-consuming, labor-intensive, and costly. As a result, many board purchasers only buy boards produced by circular multiple-blade saws, while boards from band saws have poor market demand.

Maintenance of Multiple-Blade rip Saw Blades

  1. When the cutting surface of the log multiple-blade rip saw blades becomes rough and no longer sharp, it must be promptly reconditioned. Precision is crucial during reconditioning to avoid altering the original angles and compromising dynamic balance.
  2. If the multiple-blade rip saw blades are not frequently used, they should be stored flat or hung up, covered with plastic sheets, and protected from moisture and dust to prevent rusting.
  3. For higher precision maintenance tasks such as internal diameter correction and positioning hole processing of the multiple-blade rip saw blades for logs, it is advisable, if possible, to entrust them to the manufacturer. Poor machining can result in suboptimal product performance or potential hazards. When enlarging holes, the principle is not to exceed the original diameter by more than 2cm to avoid disrupting the balance of stress.
