Analysis of processing errors
Analysis of processing errors Error in the machining principle. The error in the machining principle is that in the actual machining process of mechanical parts, the use of methods, tool contours and gear ratios similar to the theoretical machining methods will cause the resulting parameters of the part to deviate from the theory. The most […]
CNC machining center CNC method
CNC machining center CNC method There are two programming methods commonly used in CNC machining centers today: ① Simple contours – contours consisting of straight lines and arcs, directly programmed by the G code of the CNC system. ② Complex contours – three-dimensional surface contours. Use automatic programming (CAD / CAM) software to draw three-dimensional […]
Processing principles of CNC machining center
Processing principles of CNC machining center Defining the machining route The machining route of the CNC lathe feed refers to the path that the turning tool travels from the tool setting point (or fixed machine origin) until it returns to this point and completes the machining program, including the cutting path and non-cutting operations such […]
Two ways to compensate for tool length
Two ways to compensate for tool length 1) Use the actual tool length as tool length compensation (this method is recommended). Using the tool length as compensation means using the tool setter to measure the tool length, and then inputting this value into the tool length compensation register as tool length compensation. The reasons for […]
Tool length compensation
Tool length compensation The concept of tool length Tool length is a very important concept. When we program a part, we must first specify the programming center of the part, and then we can set the part programming coordinate system. This coordinate system is simply the coordinate system of the workpiece, and the zero point […]
Sharpening of turning tools
Sharpening of turning tools After the turning tool becomes dull, it needs to be sharpened to restore the correct shape and angle. Turning tools are generally sharpened on a grinding machine. Use a white aluminum oxide grinding wheel to grind high-speed steel turning tools, and a green silicon carbide grinding wheel to grind carbide turning […]
Requirements for tools in milling processing
Requirements for tools in milling processing In the process of cutting metal, the cutting part of the tool operates under conditions of greater cutting pressure, higher cutting temperature and strong friction. When cutting is uneven or interrupted, the tool will be subject to strong impacts and vibrations, so the part of the material cut by […]
Difference Between CNC Lathe and CNC Milling Machine
Difference Between CNC Lathe and CNC Milling Machine The first thing to understand is the difference between a lathe and a milling machine, not the difference between CNC. A lathe is a machine tool that mainly uses turning tools to turn rotating workpieces. Drills, reamers, counters, taps, dies and knurling tools can also be used […]
Basic angles and functions of turning tools
Basic angles and functions of turning tools The basic angles of turning tools are the rake angle (γo), clearance angle (a0), main angle (Kr), secondary deflection angle (κr’) and cutting edge inclination angle (λs). To determine the angle of the turning tool, three coordinate planes are set: the cutting plane, the base plane and the […]
C6132 (or C616) Components and functions of lathes.
C6132 (or C616) Components and functions of lathes. The C6132 lathe consists of a bed, headstock, gear box, feed box, polished rod, screw rod, drawer, tool stand, bed legs and tailstock. Lathe bed: It is the main part of the lathe. It is used to support and install various components of the lathe to ensure […]
