Tool chuck understanding

The tool chuck provides a standard connection between the various cutting tools and the machining center spindle. It works in a similar way to an adjustable drill chuck, just as a home repairman can replace a drill bit. The tool chuck provides a standard connection between the various cutting tools and the machining center spindle. It works in a similar way to an adjustable drill chuck, just as a home repairman can replace a drill bit. Machining center spindle holes and tool holders shanks and flanges are manufactured to standards that have evolved worldwide over the past 25 years. In general, these standards are well established and provide a solid, high degree of concentricity as long as both the spindle and the tool chuck meet the standards.

Tool grinding machine

As the tool material is very hard, so generally can only use grinding to change its shape. Tool manufacturing, grinding common in the tool grinder are the following:

1. Grinder machine: grinding bits, end mills and other tools slot or back.

2. Polishing angle machine: grinding cone taper angle (or eccentric angle).

3. Repair transverse edge blade: the horizontal edge of the correction bit.

4. Manual universal tool grinder: grinding cylindrical, groove, back, top corner, horizontal edge, plane, rake and so on. Commonly used in a small number of complex shape tool.

5.CNC grinder: generally five-axis linkage, the function is determined by the software. Generally used for grinding a large number of high precision, but not complicated tools, such as drill bits, end mills, reamers and so on. The main suppliers of such grinders come from Germany, Switzerland, the United States, Australia and Japan.

Diamond tool orientation choice

Diamond anisotropy, so not only the crystal surface hardness, wear resistance is different, that is, the same crystal surface in different directions wear resistance is also different. If the crystal orientation is improperly selected, the sharpening efficiency will be greatly reduced even if the crystal face is properly selected. At the same time as the diamond crystal compressive strength than the tensile strength of 5 to 7 times, so in the sharpening process to choose the easy-to-wear direction of the crystal surface, while the edge to meet the blade grinding wheel linear speed in the positive direction (that is taken Inverse grinding) to ensure sharpening efficiency and reduce the micro-level edge cleavage.
