cnc cylindrical grinder This machine is designed for the grinding of workpieces in series production operations. It is therefore ideally suited for use in the automobile industry and all sectors where small cylindrical precision components are produced in large series under economical conditions.
The most widely used workholding method for cylindrical grinding is done between centers. Between-centers grinding does not require a centerless ground workpiece. In fact, many agree that the only way to create a perfectly round part from raw stock, in one setup, is to grind between centers. Many tool designers start with this methodology in mind.
Work Head. NN bearing designed work spindle offers heavy duty load capacity, optimal rotation accuracy, and high rigidity. The servo motor drive offers steady speed and torque during the grinding operation. A positive air purge system keeps grinding swarf and coolant out of the work head, thus it prolongs its life.

In-feed grinding — also called plunge grinding — is used to grind cylindrical parts with notches or complex shapes, such as gear shafts. Here, the workpiece rest blade needs to be tooled to match the shape of the part, and the grinding and regulating wheels must be dressed to match the part's desired profile cut.

3. Cylindrical Grinding. Cylindrical grinding involves the process of grinding the outer surface of a cylinder. These surfaces may be tapered, contoured, or straight. In contrast with other CNC operations, this method resembles the lathe-turning operations.
Kinds Of Centerless Grinding. Like center-type cylindrical grinding, which can use plunge or traverse motions to grind a workpiece, centerless grinding too has different ways to get the job done. The two most common centerless grinding techniques arie infeed and thrufeed. Setting up for infeed is the less complicated of the two.

I have some time on a Fitchburg cylindrical, but was grinding all carbide with a 20" green wheel. The rest of my experience is doing (a fair amount of) cylindrical and taper work on surface and tool and cutter grinders. So take the above with a grain of salt. Maybe it will inspire others to chime in & we'll both pick up more tips. smt

Lets say I have a 20' workpiece mounted in the center on a cylindrical grinder with a 60" table with center pivot. I indicate the left and right extremities closest to zero and take a small .003 cut. Grinding wheel removes material on entire length. I take a micrometer to it and get a .010 taper (exagerated of course). My question is this:
International Tool Machine's (ITM) Universal OD Grinder was developed for grinding cylindrical or tapered parts with multiple steps or profiles. To hold the tightest tolerances the parts are clamped between high precision centers, which allow grinding along the complete part length without the necessity of reclamping.
The reciprocating motion of the wheel-head and reversal of direction in your machine can be similar to the External Cylindrical Grinder. You can swivel the work-head for doing taper grinding operation. Your machine has a coolant …
Work head can be Swiveled upto 90˚ towards grinding wheel and 30˚ towards operator for taper and conical grinding. The drive to work head spindle is given by and electric motor through V-belts.
