The machine which was originally developed to position and grind accurately straight or tapered holes only is _____

The most important development in Jig Grinder is that it can grind contour forms which may include a combination of radii, tangents, angles, and fiats.

In a Jig Grinder, holes distorted during the hardening process can be accurately brought to the correct size and position.

Using a Jig Grinder, holes and contours requiring taper or draft may be ground such that fitting of parts become easy.

Using Jig Grinder, mating parts, such as punches and dies can be finished to size, eliminating the tedious Job of hand fitting.

Because more accurate fits and better surface finishes are possible, the service life of the part is greatly prolonged.

Many parts requiring contours -can be made in a solid form, rather than in sections as was formerly necessary.

The accuracy of Jig boring machine table is

In Jig Grinding, _____________ machining principle is employed.

Identify Outfeed Grinding

Identify Plunge feed grinding.

One of the important part of a Jig Grinder is its high speed pneumatic spindle

In a Jig Grinder, it has provision for dressing of grinding wheel without disturbing work piece set up.
