No,.1,544 939 Claims. Cl Sis- 13 This. invention. appertains to a taper grinding tool and more particularly to a removable grinding head for association with any preferred type of machine, tool such as a Tree vertical milling machihassee my39Patent No. 2,664,789 issued January 5, 1954.
Another salient object of my invention is to provide a versatile precision grinding tool having both a line radial adjustment and an angular adjustment, whereby the grinding wheel can be accurately positioned for various types oi39cl39ose tolerance grinding in the making of dies, fixtures and the like.
The invention relates to a grinding head for attachment to a grinding machine for machining internal profiles, with high precision and high reproducibility characteristics, starting from a generator profile or master-cam.
The object of the invention is to provide a grinding head in a simple and convenient form.
The invention is more easily understood by reference to the following description and the appended drawing wherein.
FIG. 1 is a perspective view showing a sketch of a grinding head.
FIG. 2 is a simplified vertical section through a grinding machine comprising a grinding head according to an invention design.
A grinding dresser or wheel dresser is a tool to dress that is, slightly trim the surface of a grinding wheel. Grinding dressers are used to return a wheel to its original round shape that is, to true it up, to expose fresh grains for renewed cutting action including cleaning away clogged areas, or to make a different profile cross-sectional shape on the wheels edge.
Nbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbsp To grindmeans to abrade, to war away by friction or to sharpen.nbsp In manufacturingit refers to the removal of metal by an abrasive wheel rotating at high speedsand working on the external or internal surface of a metallic or other part hardenough to be abraded, rather than indented by the grinding wheel.nbsp Theaction of the grinding wheel is similar to that of a milling cutter.nbsp Thegrinding wheel is composed of many small abrasive particles bounded together,each one acting as a miniature cutting point.
Base It has a driving mechanism hydraulic device,tank and motor. It has column at the back for supporting the wheel head.
May 01, 1984nbsp018332Shank tools are relatively simple to design and apply. However, their inherent drawbacks--longer cycle time and shorter life--have resulted in an increasing use of rotary diamond dress rolls for forming and dressing grinding wheels. Rotary dressers are far more complex than shank tools. They are generally motor driven.
The work rest located between the grinding and regulating wheel supports the workpiece. The regulating wheel is usually a rubber-bonded wheel of the same grit characteristics as the grinding wheel. It Figure L-16 Roll grinding machine for grinding steel mill rolls. Figure L-17 Principle of the centerless grinder.
If there is no driving equipment for the machine tool, taking into account the dressing clamp, processing method and the size of the diamond rotary dresser. 6.5 Grinding parameters It includes the linear velocity of grinding wheel, RPM of the workpiece, feed amount, feed speed, dressing cycle, grinding.

The design value of the outer diameter of the reamer is too small The cutting speed is too low The feed rate is too large The main deflection angle of the reamer is too small The cutting fluid is not selected properly The worn part of the reamer is not worn off during sharpening, and the elastic recovery reduces the aperture When reaming steel parts, the margin is too large or the reamer is not Sharp, easy to produce elastic recovery, so that the hole diameter is reduced The inner hole is not round, and the hole diameter is unqualified.
Although wheel dressing is often done manually between work cycles, some grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life.
Modify the size of the pre-processed aperture Reduce the material hardness or switch to a negative rake angle reamer or a cemented carbide reamer Control the swing error within the qualified range Increase the entering angle Pay attention to timely removal of chips or use a bladed angle reamer Pay attention to the quality of sharpening.
