Frequently Asked Questions

Technical Information

  • Turning

    The main turning operations in lathes are named either by the name of the cutting tool used or by the turning operation performed.


    • Examples of these are taper turning, drilling, threading, grooving, cutting, reaming, etc. can be given.
    • Turning is a combination of two movements. Rotation of the workpiece and advance motion of the tool. The feed motion of the tool can be along the axis of the workpiece, which means that the diameter of the part will be reduced to a smaller size.

    Internal Diameter Turning

    It is the process of enlarging the inside diameter of the hole along the axis of the workpiece and giving the desired shape with the rotation of the workpiece and the advancement movement of the tool.


    External Diameter Turning

    With the rotation of the workpiece and the advance movement of the tool, the chip removal from the diameter and the face along the part axis is the process of lowering the part to a smaller diameter and length.

  • Grooving

    It is the process of opening channels in the desired size range on the workpiece on the lathe or cutting the workpiece in the desired length.

    We can group grooving and cutting operations as following;


    • External diameter grooving
    • Internal diameter grooving
    • Faceplate grooving
    • Cutting
  • Threading

    In turning and milling machines, it is the outer diameter of the part or the desired pitch in the hole, depending on the thread type (metric, whitworth, gas thread, etc.) or special threading processes.

    We can apply these processes by removing chips from the part or by crushing method.

    We can briefly exemplify various threading methods as following;


    • With guide
    • By Rubbing
    • With thread comb
    • With thread mill
    • By hobbing
    • With thread tips
  • Milling

    It is called chip removal by moving according to the form of the part on the workpiece with the fixed, rotating movement of the cutting tool around its own axis.

    We can exemplify milling operations as following;


    • Surface milling
    • High Feed
    • Cocoon Grooving
    • T Grooving
    • 90 degree milling (side wall milling)
    • Rough milling
    • Finish form milling
    • Pool draining
    • Chamfering
    • Hole enlargement
  • Drilling

    It is the process of drilling holes in the workpiece in the desired dimensions on lathe, milling or drill benches.

    In the milling and drilling machine, the workpiece can be drilled with the rotational movement of the fixed cutting tool around its own axis.

    In the lathe, the workpiece rotates around its own axis and drilling can be done by the linear movement of the cutting tool.

    We can exemplify drilling tools as following;


    • With carbide drill
    • With a plug-in drill
    • With U-Drill
  • Boring

    It is a precision hole machining process in the desired dimensions on the workpiece. The desired dimensions on the bar can be precisely adjusted and micron-sized chip removal can be performed.
