We all know lunan seiko manufacturing machine tools, so what is the processing center operation skills? Machining center is composed of mechanical parts and CNC system two parts, on behalf of the high level of development of today's machine tool industry, due to the continuous reduction of the price of machining center, has not been like the original only large enterprises can afford to buy equipment, now there is a common processing plant is not what a new one or two.
Machining center is CNC system highly integrated equipment, high processing accuracy, processing efficiency has become an indisputable fact, but any processing equipment has its processing skills, machining center is not included, this paper briefly introduces the machining center operation skills:
As a skilled operator processing personnel, to understand the requirements of processing parts, process route, machine characteristics, before the machine to complete the processing tasks.
1) Fixture should have as few components as possible and high stiffness.
2) Ensure that the workpiece processing content is completed within the range of the spindle stroke.
3) The contact between the bottom surface of the fixture and the workbench, the flatness of the bottom surface of the fixture shall be guaranteed within 0.01-0.02mm, and the surface roughness shall not be greater than Ra3.2μm.
4) To ensure that the installation orientation of parts is consistent with the direction of workpiece coordinate system and machine tool coordinate system selected in the program, and directional installation.
5) It can be disassembled in a short time and changed into a fixture suitable for the new workpiece. Because the auxiliary time of machining center has been compressed very short, the loading and unloading of supporting fixtures can not take up too much time.
6) For the machining center with interactive workbench, due to the movement of the workbench, up, down and rotating action, fixture design must prevent the space interference of fixture and machine tool.
7) The fixture should be open as far as possible, the space position of the clamping element can be low or low, and the installation fixture can not interfere with the tool track of the working step.
8) Try to complete all the processing content in one clamping. When the clamping point must be replaced, special attention should be paid not to destroy the positioning accuracy due to the replacement of the clamping point, which should be explained in the process document if necessary.
9) In order to simplify positioning and safety, each positioning surface of the fixture relative to the processing origin of the machining center, should have precise coordinate size.
