Combining hard turning and grinding into a single machine platform gives the process engineer much greater flexibility to handle strengths of each operation. A process can be optimized more easily using both hard turning and grinding in a single workpiece handling rather than moving the work from one machine to another. What Kind Of Machine?
TURNING OPERATIONS INTRODUCTION : •This operation is one of the most basic machining processes. That is, the part is rotated while a single point cutting tool is moved parallel to the axis of rotation. •Turning can be done on the external surface of the part as well as internally (boring).
This process has two advantages; the turning process is considerably faster than grinding flat surfaces and wear and tear on the grinding tools is vastly reduced with only finish grinding operations carried out. Since the workpiece is machined in a single setup, the whole process is more efficient than when carried out on two machines.
Turning is usable on the outside of a cylinder or on the inside. The latter operation is called boring. Grinding. CNC grinding machines use a rotating grinding wheel to remove material. The objective is to give a high precision finish to a metal part. The achievable surface quality is very high.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
On Ukrainian front, grinding war and weary anticipation of invasion But after eight years in the trenches, there is a weary acceptance that the status quo cannot last forever, that the Russian military, which dwarfs their own in power and wealth, will likely come sooner or later.
Turning, drilling, boring and grinding can all be performed in a single part handling. The second spindle picks off the workpiece from the first to allow back-working operations. Conventional metalworking practice suggests that processing hardened, precision, parts-of-rotation should be done in proper order. Blanks are first cut to length.
