Specification: Gear ratio: 4:1 Roller Width left up: 85mm Middle Roller width: 50mm Round Diameter: 60mm Maximum opening: 0-5 mm Flat area ( /- 0.01mm): 53 mm Square wire (+/-0.01mm): 1,1.5, 2, 2.5, 3, 4, 6 Round wire (+/-0.01mm): 2,3,4,5,6,8 Combination Round length shape: 120mm Ring shank - half round ellipse(mm): 2.5x1, 3x1.25, 4x1.5mm Features: Thickness of up to 6MM The thinnest can reach 0.03mm The handle can be installed on the left or right side 60 HRC durable metal Cut with V shaped grooves Suitable for gold, silver, copper, aluminum, and other metals with good ductility. 3 IN 1 Rolling Mile Consists of two smooth, highly polished, hardened steel rolls, mounted in the housing parallel to each otherDesigned to produce thinner sheet metal and wire gauges, create round grooves and square grooves of different specifications.Half of the roll is smooth(for sheet metal) and half is grooved (for wire). Handle adjustment gear The pinion drives the oversized gear to save effort and makes the pressed metal flakes more even.The distance between rollers can be easily adjusted by the top gears.Reduction gear ratio of 4:1 allows the rollers to make one complete turn for every four turns of the rolling mill handle. Heavy-Duty & Stable With forged handle, simple and convenient to use. Easily mounts the rolling mill to your workbench using the mounting holes.The outer 3 mm of the rolls are hardened to around 60 HRC for superior deformation resistance.All powder-coated body for superior corrosion protection and appearance. Steps for usage: first of all, please fix the machine on a firm object (figure 6)then install rocker (FIG. 1)Rotate the two drum balancing gears to the bottom at the same time (FIG. 3)Install lifting drum gear (FIG. 2)Remember to inject lubricating oil before using the machine. Lubricating oil must be injected wherever there is a transmission (FIG. 4) (lubricating oil must be injected on both sides of the injection holes marked in the picture)After the above steps are completed, it can be processed and used on the roller (figure 5) Guidelines： 1--rocker 2--Lifting drum gear 3--Drum balance gear 4--Lubricating oil injection hole 5--forming drum 6--Machine fixing hole
