今天的动力工具不仅不受限于我们的视野,也不受限于我们的研究方法。它们主要用于磨光、钻削、铲切和螺钉、螺帽的紧卸。目前,“设计”动力工具实际上是在稳步的发展使工具更适合使用条件。现在人们对动力工具的要求不仅仅是能用于一些厂矿的特殊场合,而且也考虑它们对人体的影响。事实上,很多工具制造厂商除讲究工具的效果外,还注意到起动、冲击、振动等问题。现在我们要力求对工具与操作者的相关问题提供相应的科学与技术。这也意味着研究人的工作能力和所能接受的环境。重点是噪声、振动、重量、平衡和操作 Today’s power tools are not limited to our vision, nor are they limited to our research methods. They are mainly used for polishing, drilling, scooping, and unloading of screws and nuts. At present, the “design” power tool is actually developing steadily to make the tool more suitable for use conditions. Nowadays people’s requirements for power tools are not only applicable to special occasions in some factories and mines, but also consider their impact on the human body. In fact, many tool manufacturers not only pay attention to the effects of tools, but also notice problems such as starting, impact, and vibration. Now we must strive to provide relevant science and technology to the problems related to tools and operators. This also means researching people’s ability to work and the environment they can accept. The emphasis is on noise, vibration, weight, balance and operation
