Supal Carbide Reamer with Flat End for your CNC Machining
High dimensional accuracy: good stability of cemented carbide material and high manufacturing precision of flat bottom reamer cutting edge can make the hole size error after processing extremely small, which can control the hole tolerance in a very small range to meet the requirements of precision parts processing. For example, in aerospace parts processing, the hole size accuracy requirements are harsh, it can accurately ensure that the hole diameter meets the design standards.   Excellent shape accuracy: The flat bottom design enables the reamer to ensure the flatness and straightness of the bottom of the hole when machining blind holes, so that the cylindricity and other shape accuracies of the holes are good, which provides a reliable basis for the subsequent assembly and use of parts.   Low roughness: high hardness and wear resistance of cemented carbide, sharp and durable cutting edge of reamer, smooth cutting during machining, little extrusion and scraping on the hole wall, low surface roughness of the machined hole wall, which can reach Ra0.4 - Ra1.6μm, making the parts more beautiful and facilitating the installation of seals and fittings inside the holes. Strong durability: The high hardness and good thermal hardness of cemented carbide allow the flat bottom reamer to maintain the sharpness and integrity of the cutting edge under high speed and high load cutting conditions, and it is not easy to wear and breakage. Compared with ordinary reamers, it significantly reduces the frequency of tool change, improves machining efficiency, reduces tool costs, and is suitable for large-volume hole processing. Small cutting force: Reasonable tool geometry parameters design, with the advantages of carbide material, so that it cuts smoothly during cutting, small cutting force, can reduce machine power consumption, reduce the deformation of the workpiece, especially suitable for thin-walled, easy to deform the parts of the hole machining.
