The present invention discloses a scrap removing device for cutting a wheel rim which comprises a main body having a working surface, a wheel rim positioning member, a first blowing member and a second blowing member sequentially disposed on the working surface from a top side thereof.

A kit for making an aperture in an object of interest comprises: a hand-held tool configured for securing a milling cutter therewithin and a guiding member conformally shaped to the aperture. The guiding member is securable to a portion to be removed of the object of interest. the guiding member has a rim. The hand-held tool is provided with a bulge guidable by the rim such that such the milling cutter, when being manually movable along the rim, cuts the aperture in the object of interest.

An intelligent tungsten carbide cutter may include a shank, at least a cutting portion, and a sensor. The shank made of tungsten steel comprises a first end, a second end, and at least a first connecting portion, and the first connecting portion is located adjacent to the second end of the shank. The shank and the cutting portion are thermally connected through high frequency oscillation heating method, and the cutting portion is secured on the first connecting portion of the shank. An accommodating channel axially penetrates through a center portion of the first end of the shank and extends toward the second end, and the sensor is installed in the accommodating channel so as to be positioned close to the cutting portion, thereby achieving the direct and accurate sensing.

Disclosed is a machining center. The machining center includes a bed structure deflected along a deflection curve by a load distribution thereon, a palette structure secured to a first end portion of the bed structure, a spindle assembly to which a machining tool is secured and secured to a second portion of the bed structure, a table movably secured to the bed structure such that a table loading is applied to a load point of the bed structure and an automatic aligner automatically detecting first and second installation errors of the table and the spindle assembly and automatically correcting the first and the second installation errors such that the workpiece and the tool are aligned with each other. The misalignment between the workpiece and the tool is automatically detected and corrected in the machining center.

The present invention relates to a machining center, and more particularly, to a machining center which allows a bed and a column to be integrated, thereby being capable of reducing the overall size of the apparatus and saving production costs and allows vibrations and displacements occurring in each of 5 axes to be rapidly transmitted to other axes to minimize relative vibrations and displacements between the axes, thereby being capable of performing high-precision machining.
