Common machining problems in vertical machining centers

Vertical machining centers often have various problems in actual processing and production. In order to better improve the processing efficiency and ensure the processing quality, this paper summarizes the common problems of vertical machining centers, and gives effective improvement methods to debug the cutting speed, feed and cutting depth more accurately. Common problem 1: Overcutting of workpieces

The accuracy of the workpiece when machining the horizontal machining center

First, the error synthesis method to eliminate the error of the machine tool itself is the most important way to ensure the final processing accuracy of the workpiece. The error synthesis method requires the measurement of the original errors of each axis of the machine tool. Because of its high measurement accuracy and flexible application, laser interferometer is the primary testing instrument for horizontal machining centers.

What are the advantages of horizontal machining centers?

Horizontal machining center is a CNC machining center planned from scratch on the basis of the general CNC machining center, which is compared with the general CNC machining center is that the speed is faster than the general CNC machining center, the fast displacement speed is faster than the general CNC machining center, and many adjustments and optimizations have been made in the mechanical structure.

What aspects should be paid attention to in the design of vertical machining centers

1. Site selection environment requirements. The location should be away from vibration sources, avoid direct sunlight and thermal radiation, and avoid the influence of moisture and air flow. If there is a vibration source near the CNC machine, anti-vibration grooves should be set around it.

Design requirements for CNC lathe feed system

In the mechanical transmission device of CNC machine tools, the linear feed movement mainly has three directions: transverse, longitudinal and vertical, namely X, Y and Z; The feed axis of CNC lathes is X axis and Z axis, and the CNC milling machine or machining center is X, Y axis and Z axis. Whether it is a CNC lathe or a machining center machine tool, their horizontal feed shaft and vertical feed shaft are basically the same in structure, mainly composed of transmission part and support part. The installation of the vertical feed shaft needs to consider the self-locking of the lead screw to prevent the headstock from sliding due to a sudden power failure, so a brake device must be installed.

Horizontal machining center coaxial hole turning machining and alignment

The horizontal machining center coaxial hole turning processing is aligned, and in the production, parts with high coaxial hole system accuracy and large span are often encountered. Such coaxial holes are difficult to machine. If it is processed on a vertical machine tool and boring is used, it is impossible to find a suitable boring bar. Due to the slender and poor rigidity of the boring bar, it is difficult to ensure the machining accuracy of the coaxial hole system. Coaxiality and surface roughness cannot be guaranteed with extended drills. In addition, due to the turning and clamping process, it is difficult to guarantee the coaxiality and parallelism of the holes. Therefore, processing by conventional methods not only cannot meet the requirements of drawings, but also brings certain losses to production.

What do I need to pay attention to when using a horizontal machining center?

Installation environment of horizontal machining center: should be installed away from the source of the earthquake, away from direct sunlight, no thermal radiation and humidity. If there is a seismic source near the installation site of the horizontal machining center, a seismic groove should be set around the horizontal machining center.

Four precautions in the use of horizontal machining centers

Horizontal machining centers should be installed away from the source of the earthquake, away from direct sunlight, thermal radiation and moisture. If there is a seismic source near the installation site of the horizontal machining center, anti-vibration grooves should be set around the horizontal machining center. If the anti-vibration groove is not installed, it will directly affect the machining accuracy and stability of the horizontal machining center, and over time, it will affect the poor contact and failure of electronic components, and affect the reliability of the horizontal machining center.

Temperature and humidity directly affect horizontal machining centers

Horizontal machining centers can generally only work normally in an environment below 30. Generally, the distribution box of the horizontal machining center is an exhaust fan and an air cooler to ensure that the electronic parts and machining work at a constant temperature. If the temperature and humidity are too high, the service life of each part of the control system will be reduced, resulting in an increase in unprovoked failures of horizontal machining centers. If the humidity increases, the dust on the integrated circuit board will increase, directly causing poor contact and short-circuit failure.

Three common problems in vertical machining centers

In the specific production of vertical machining centers, various problems usually arise. In order to improve production efficiency and ensure production quality, the network Xiaobian summarizes the common problems of vertical machining centers, and provides reasonable and effective improvement methods, so that everyone can adjust the cutting speed, feed and cutting depth more accurately.
