PURPOSE
The DSNA-42/RR planer is designed for planing a layer of wood on one side of an element in order to obtain its specified thickness and appropriate surface roughness. To obtain straightness, the lower surface of the element should be prepared on a planer.
The thickness of the planed layer and the feed speed depend on the width of the planed element and the desired surface smoothness.
The machine is intended only for operation with a central or individual sawdust extraction.
DESCRIPTION
The compact body of the welded construction guarantees good operation of the mechanisms placed in it. Top cover – opened allows quick and easy access to all points of adjustment and lubrication of the mechanisms of the knife shaft subassembly and feed rollers. The knife shaft is mounted in rolling bearings. The feed rollers are driven by a motoreducer through a chain transmission. The cast iron table of the machine tool is guided in the vertical guides of the machine body.
The desired thickness of the processed material is obtained by setting the table in relation to the knife shaft. To improve work safety, the machine has: all rotating elements covered, anti-kickback pawls protecting the operator against the kickback of the processed material. In addition, to increase safety during adjustment, sharpening and replacement of knives, the machine tool is equipped with a device that prevents the machine tool from being turned on when the top cover is open. The main drive motor has an electromechanical brake, which allows for a quick stop of the machine tool.
