1. Damage caused by splashed chips and protection measures
In lathe processing, no matter what kind of steel your project is, it has good toughness. Chips produced by turning riches plastic crimp, sharp edge. So when you cut steel in a high speed will form a red, hot and long chip, which is very easy to hurt people. And these long chips often wound on workpieces, turning tools and knife rest. So, these chips should be cleaned or broken with iron hook in time. Sometimes we should stop the machine to clear those chips if necessary. But it is not allowed to clean or break them by hands. In order to avoid damage caused by hot chips, we often break them, control the direction of chip flow and add a variety of protective baffles. Measure we take to break chips is to grind out cutting grooves or steps on turning tools, or adopt appropriate chip breaker and adopt mechanical clamping tool.
2. Installation of workpieces
In the course of turning, there are a large number of damages caused by improper installation of workpieces, such as damages to machine tools, breaking or bumping of cutting tools, and falling or flying of workpieces. All of these may get people injured. Therefore, in order to ensure safety during turning processing, we must pay more attention on clamping workpieces. Choose appropriate fixture for those workpieces with different sizes and shapes. No matter its three jaw or four jaw chuck or special fixtures, its connection with spindle must be stable and reliable. When it comes to workpieces, we need to clamp it appropriately and tightened. To tighten large pieces, you can use sleeve to ensure that the workpiece can sustain high-speed rotation and strong cutting force without shifting, falling off and throwing out.
3. Safe operation of turning machine
Before launching machine, you should check your machine tool and confirm it is in a good condition. Make sure the clamping of workpiece and cutting tool are in a correct position. Workpieces on the machine should be firm and reliable. If you need to change cutting tools on machine, first step is to stop your machine. Do not touch or wipe your workpiece with cotton thread when it is rotating. Cutting speed, feed and laboring depth should be selected properly. It is not allowed to do overload processing. The head of your machine, your knife rest and surface of your machine must not place workpieces, work fixtures or any other sundry. When using a file, you should move turning tools to a safe position. Except specialized person, no one should be allowed to use or maintain machine tools.
Remember these things in your mind and keep yourself away from danger. Always remember, safety is the first.
