我厂是砂轮制造专业厂,生产中需要大量不同规格圆垫板。经过多次摸索我们利用旧三爪卡盘自制成功了圆周气割装置(见图)。一年多来的生产实践表明,该装置具有转动灵活、使用方便、可任意调节加工尺寸、与手工切割相比切割效率可提高2～3倍的优点。这种装置加工误差为1～2毫米,光洁度可达▽_3,切割钢板厚度为6～100毫米。 I plant is a professional manufacturer of wheel manufacturing, production requires a large number of different specifications round pad. After repeated exploration we used the old three-jaw chuck self-made circular gas cutting device (see photo). More than a year of production practice shows that the device has the flexibility to rotate, easy to use, can be adjusted processing size, compared with manual cutting cutting efficiency can be increased by 2 to 3 times the advantages. This device processing error of 1 to 2 mm, smooth up to ▽ _3, cutting steel thickness of 6 to 100 mm.
