Benefits of technology

The patent describes an apparatus for cylindrically grinding workpieces. It includes a first holding tool for positioning pre-grinding workpieces, a second holding tool for positioning partially ground workpieces, and a first grinding wheel for grinding the pre-grinding workpieces. The first grinding wheel has a semicircular bottom wall and two slanted walls connected with it. The technical effect of this invention is to provide a more efficient and precise method for cylindrically grinding workpieces.

Problems solved by technology

However, the central apparatus can only cylindrically grind one workpiece at a time.

Embodiment Construction

[0017]Referring to FIGS. 1-5, in a preferred embodiment, an apparatus for cylindrically grinding workpieces, includes a first grinding wheel 10, a first holding tool 20, a second holding tool 30, and a second grinding wheel 40. The holding tools 20, 30 are configured for positioning workpieces 60. In this embodiment, the workpieces 60 are optical elements, such as infrared cut filters and ultraviolet cut filters.

[0018]Referring to FIG. 3, the first holding tool 20 defines a first groove 24 for containing pre-grinding workpieces 60. The pre-grinding workpieces 60 can be optical elements having a non-cylindrical shape. In this preferred embodiment, the workpieces 60 are in substantially square form. Therefore, the first groove 24 is configured to have a V-shaped cross section, for compliantly receiving the pre-grinding workpieces 60 therein. Understandably, the cross section of the first groove 24 can be of other shape depending on the form of the pre-grinding workpieces 60. The pre-g...

Abstract

An exemplary apparatus for cylindrically grinding workpieces (60) includes a first holding tool (20), a second holding tool (30), and a first grinding wheel (10). The first holding tool is configured for positioning pre-grinding workpieces, and the first holding tool defines a first groove (24) for containing the pre-grinding workpieces to be partially ground. The second holding tool is configured for positioning the partially ground workpieces, and the second holding tool defines a second groove (34) for containing the partially ground workpieces. The first grinding wheel is configured for grinding the pre-grinding workpieces in the first holding tool. The first grinding wheel defines a first grinding groove (104), and the first grinding groove is defined by a semicircular bottom wall (1042) and two slanted walls (1044) connected with the semicircular bottom wall.

Description

FIELD OF THE INVENTION [0001]The present invention generally relates to cylindrical grinding apparatuses and, more particularly, to a holder for holding workpieces during a cylindrical grinding process.DESCRIPTION OF RELATED ART [0002]Usually, optical elements such as camera lenses and spectacles are in used in cylindrical form. However, original optical workpieces (i.e. lens blanks) are most easily manufactured in the form of a square. Therefore, these original optical workpieces have to be cylindrically ground before use.[0003]A typical example of a contemporary cylindrical grinding apparatus is a central apparatus. The central apparatus typically includes a pair of holders for holding the original workpiece, where each holder has a hollow chamber communicating with a surface of the holder. The holder can hold the workpiece on its surface by using an air pump pumping the hollow chamber, a grinding wheel is then used to cylindrically grind the workpiece. However, the central appara...
