    Indexable Negative Carbide Lathe Inserts VNMG160408 For Cutting Tool Holder

    Indexable Negative Inserts VNMG160408 For Cutting Tool Holder DVVNN/DVJNR/L


    Application:


    Carbide inserts are replaceable and usually indexable bits of cemented carbide used in machining steels, cast iron, high temperature alloys, and nonferrous materials. Carbide inserts allow faster machining and leave better finishes on metal parts. Carbide inserts can withstand higher temperatures than high speed steel tools.


    For Roughing, use a tough coated insert grade with a large nose radius, heavy honed cutting edge and large chipbreaker. Cut at a low SFM with a large Depth of Cut (ap) and high Feed Rate per Rev. (fn)

    For Universal, use a hard, tough & wear resistant coated insert grade with a medium nose radius, honed cutting edge and medium chipbreaker. Cut at a medium SFM with a medium Depth of Cut (ap) and medium Feed Rate per Rev. (fn)

    For Finishing, use a hard & wear resistant coated insert grade with a small nose radius, sharp to light honed cutting edge and small chipbreaker. Cut at a high SFM with a medium Depth of Cut (ap) and medium Feed Rate per Rev. (fn)


    Optimum: Insert Wear, decrease Spindle Speed (n) and/or increase Feed (fn) or change to a harder insert grade. Insert Chipping, increase Spindle Speed (n), decrease Feed (fn), and/or change to a heavier honed edge or change to a tougher insert grade.


    Coolant: Use Coolant, if the insert grade allows, and always use high pressure coolant to remove the hot chips and heat from the insert to reduce thermal shock


    C and W type turning inserts are often used for rough machining due to their larger point angle, which makes them more rigid. Inserts with a smaller point angle, such as D and V, are often used for finish machining. Although they have less strength, the smaller angle can reach more part details.


    1. Substrate - The alloy carbide's properties, grain size, and cobalt content.

    2. Geometry - The physical characteristics of an insert that differentiates one shape from the next.

    3. Tolerances - The allowed deviation of all insert dimensions.

    4. Relief Angle - The angle measured from the vertical line perpendicular to the cutting edge of the insert and the cutting face of the insert.

    5. Rake Angle - The angle formed on the insert from the top surface area and the bottom of the insert chip flow area when parallel to the floor. 6. Chipbreaker - The formed groove or recess along the cutting edge of the insert that breaks chips into small manageable lengths.

    7. Edge Preperation - The process used to prepare the insert's edge cutting condition for specific application and material. Achieved by honing, chamfering, "T" land or any combination there of.

    8. Coating - Thin layer of titanium nitrade on the surface of the insert that allows for greater cutting speeds, wear resistance and longer insert life.

    9. Grade - A combination of substrate and coating that determines the hardness and toughness of the insert.


    Description:


    Turning inserts employ highly engineered composite structures, coatings, and geometry features to achieve great accuracy and high material removal rates. The benefits of using replaceable inserts for turning tools include: ·

    1. Some inserts can be indexed to use other edges when one becomes worn ·

    2. Inserts are quickly and easily replaced at the machine


    Turning tool is the most widely used tool in metal cutting without signature.It can be machined on lathe outside circle, end plane, thread, internal hole, also can be used for cutting groove and cutting.On the structure, the tool can be divided into integral tool, welding assembly tool and mechanical clamping blade.Mechanical clamping blade's turning tool can be divided into machine tool turning tool and indexable turning tool.The cutting performance of mechanical clamping tool is stable, and workers do not have to grind it, so it is applied more and more in modern production.


    CVD-coated carbide grades use ceramic thin film coating technology and provide stable, efficient machining at high speeds. They are also the right choice for heavy interrupted applications.

    Benefits of CVD-coated carbide

    CVD-coated carbide is suitable for low- to high-speed machining, from finishing to roughing. High toughness and crack resistance result in stable machining.

    The various combinations with 3D chipbreakers solve problematic chip evacuation and enable high-speed machining at high feed.
