Vertical machining centers are easy to install, operate, observe machining conditions, debug programs, and have a wide range of applications. Below we will explain the common problems and solutions during the use of vertical machining centers.
3+2 positioning machining and 5-axis linkage machining are suitable for different industry objects. 5-axis linkage machining is suitable for surface machining, while 3+2 positioning machining is suitable for flat machining.
When milling, the teeth start cutting from the surface of the workpiece each time, so it is not suitable for processing workpieces with hard skin. During reverse milling, due to the high friction between the cutting teeth and the workpiece, the cold hardening phenomenon on the machined surface is more severe.
Thermal deformation is one of the common factors affecting the positioning accuracy in ball screw systems. Here are some methods to deal with the effects of thermal deformation: Choose appropriate materials: choose materials with good thermal stability and low thermal expansion coefficient, which can reduce the impact of thermal deformation on the system. Common choices include high-strength materials such as stainless steel and aluminum alloy.
Do you know what 7:24 in BT knife handle represents when dealing with knife handles every day? The tool holder is the connecting body between the machine tool and the cutting tool. It is a key link that affects concentricity and dynamic balance, and should not be treated as a general component. Concentricity can determine whether the cutting amount of each cutting edge of the tool is uniform when it rotates once; Dynamic imbalance during spindle rotation will generate periodic vibrations.
If the spindle speed is abnormal, that is, after the spindle is given a command speed, the response speed on the CNC machining center is not consistent with the command speed (usually less than the command speed). Perhaps the spindle of the CNC machining center is not smooth and there are abnormalities. The sound is loud and slow, and in some cases, the motor may even trigger an overcurrent alarm. For the spindle of a CNC machining center, in response to the encoder, the speed command "S" given by the CNC machining center machine is followed by a number, which will reflect the same value on the system flash.
