FIELD: process engineering.
SUBSTANCE: proposed mill comprises stationary bed with guides, working stand driven by drive cod-rods to reciprocate in guides, top and bottom rack engagement, intermediate and front cartridges, pipelines connected to tank with lubricant-coolant and devices to feed the latter into strain source connected with pipelines located at stand inlet and outlet. Invention differs from known designs in that lubricant-coolant feed device located at stand inlet, behind the intermediate cartridge, is composed of sprayer mounted at the frame secured at the bed. Note that lubricant-coolant feed device at stand outlet is composed of circular support secured at front cartridge and provided with crossbars. Aforesaid sprayer is hinged therefrom and made up of two hollow cases opening at replacing front cartridge cams. Casing for wiring is arranged between said crossbars screwed to circular support to prevent sprayer opening in rolling. Sprayers are furnished with channels to feed lubricant-coolant to top rack engagement from stand inlet and outlet sides.
EFFECT: higher reliability, ruled out loss of lubricant-coolant at reciprocating mill stand.
