what are the processing processes of the horizontal machining center? the horizontal machining center refers to the machining center in which the spindle axis is parallel to the worktable, and is mainly suitable for machining box parts. his working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different tools, automatically change the spindle speed of the machine tool, and complete the multi-process processing on multiple surfaces of the workpiece in turn. its advantage is that it can greatly improve the production efficiency, but it occupies a large area and costs a lot.
the control system can control the machine tool according to different processing procedures, automatically select and replace the tool, automatically change the machine tool spindle speed, feed rate and the movement track of the tool relative to the workpiece and other auxiliary functions, and sequentially complete the multi-process processing on multiple surfaces of the workpiece. and there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
due to the concentration of processes and active tool change, the machining center reduces the time for workpiece clamping, measurement and machine tool adjustment, so that the cutting time of the machine tool reaches about 80% of the time when the machine tool is started (common machine tools are only 15-20%);
at the same time, it also reduces the workpiece turnover, transfer and storage time between processes, shortens the production cycle, and has significant economic effects. the machining center is suitable for the production of small and medium batches with complex shapes of parts, high precision requirements, and frequent product replacements.
when using a horizontal machining center, we do not pay special attention to its operation points, and some detailed problems are often easily overlooked.
1. ensure that the processing content of the workpiece is completely completed within the stroke range of the spindle.
2. try to complete all processing contents in one clamping. when it is necessary to replace the clamping point, special attention should be paid not to damage the positioning accuracy due to the replacement of the clamping point, and clarify it in the process document if necessary. .the contact between the bottom surface of the fixture and the worktable, the flatness of the bottom surface of the fixture must be guaranteed within 0.01-0.02mm, and the surface roughness is not greater than ra3.2um.
3. the fixture should have as few components as possible and high rigidity.
4. in order to simplify the positioning and installation, each positioning surface of the fixture has the appropriate coordinate scale relative to the processing origin.
