| 摘要 |
The present invention relates to a grinding machine (100) comprising: tool spindles (1, 1.1) for accommodating a grinding tool (2) around a tool rotary shaft (B) and being driven in order to be rotatable; a first workpiece spindle (3) for accommodating a first workpiece (C1); and a second workpiece spindle (4) for accommodating a second workpiece (C2). The first workpiece spindle (3) and the second workpiece spindle (4) are arranged in the lateral side of the longitudinal direction of the grinding tool (2) accommodated in the grinding spindle (1), both workpiece spindles (3, 4) are arranged in parallel, the grinding spindle (1) is mounted so that displacement is possible along a first linear guide (5) extended to be parallel to a horizontal tilt axis (Y), the first workpiece spindle (3) and the second workpiece spindle (4) are separated from the horizontal tilt axis (Y) in the same vertical and horizontal distance (a1), and the tool rotary shaft (B) forms an acute angle (W) greater than 0° by including the horizontal tilt axis (Y) in a horizontal projection method. |
