YUKO Flex Horn #SC120 BC Type Silicon Carbide Shaft Diameter 4.3mm SC120 BC-12.7 1 Piece

Catalog number: BC-12.7 Features: ● A structure with balls made of sintered artificial abrasive grains attached to the fiber resin feet protruding from the shaft. ● The feet are made of nylon resin and are highly elastic, so they can be used to polish burrs and uneven surfaces on the inside of workpieces. Applications: ● SC (silicon carbide) Workpieces made of relatively hard materials (cast iron, carbon steel, hardened iron, etc.) ● AO (alumina oxide) Workpieces made of relatively soft materials (aluminum, stainless steel, copper, etc.) <Coarse grain size> #60, 120, 180, mainly for deburring <Fine grain size> #240, 320, 600, mainly for polishing <LA rubygate alumina> #1000 equivalent (for mirror finishing) (#20, #40, #80, #400, #800 are available as special orders) ● Deburring, polishing, finishing, and chamfering the inner surfaces of cylindrical parts of various equipment and parts. ● Honing finish for internal combustion engines, hydraulic cylinders, and various other cylinders. ● Rust removal, cleaning, and polishing of the inside of tubes and pipes. Specifications: ● Shaft diameter (mm): 4.3 ● Suitable inner diameter (mm): 12.0-13.5 ● Total length (mm): 203 ● Abrasive grain: silicon carbide ● Abrasive grain length (mm): 63 ● Shaft diameter (mm): 4.3 ● Rotation speed varies depending on the workpiece, but is used between approximately 300 and 1200 rpm ● Working time varies depending on the material of the workpiece and the purpose of use, but as a guideline, it is 10 to 20 seconds, and the reciprocating motion is approximately one reciprocating motion every 2 seconds ● Grinding fluid is an aqueous solution (solub type) or spindle oil ● Tools used: electric drill, drill press, machining, etc. Material/Finish: ● Abrasive grain: silicon carbide ● Shaft: galvanized wire ● Brush part: nylon
