High-speed die cutting machine with high efficiency, high precision, high hardness hard material cutting, high surface quality of the workpiece a series of advantages, is to solve the aviation engine blade mold manufacturing an effective means. To date, high-speed cutting technology is the most widely used and most successful in the aerospace, automotive and mold industries. Applications in the aviation industry focus on the high-speed cutting of the overall structural components of aircraft and high-alloy parts of aeroengines (mainly blades), while the technologies and processes related to high-speed milling of aero-engine compressor blades and turbine blade molds are concerned Not many people.
High-speed mold machine process generally consists of the following components:
Process is one or a group of workers in a work area for the same or at the same time on several parts of the continuous completion of that part of the process. It is the basic part of the process, but also the basic unit of production planning and economic accounting. It is also the basis for determining the load of equipment, equipping workers, arranging homework and the quantity of tools. Whether the division is the same process is mainly based on the work place (equipment), the processing object (workpiece) is changed and the processing is completed continuously. If one of the changes or processing is not completed in succession, it should be classified as another process.
How to determine whether a workpiece in a working place is continuous processing? Now a batch of workpiece on a hole drilling, hinge processing as an example. If each workpiece is drilled in the same machine and then reaming, then the hole drilling and reaming process is continuous, should be considered the same process. If all the workpieces are drilled through the hole on the machine tool and then reaming one by one, the drilling and reaming process on a workpiece is not continuous. The drilling and reaming processes should be divided into two processes. For another example, in the "machining center" machine tool mold parts complex cavity, as long as not to the processing of another part, then all the processing belong to the same process.
Installation is the workpiece (or assembly unit) after a folder that part of the process completed. A process can be installed only once, but also can be installed several times.
For example, both sides of the car belong to a process, but need two clamping. More than one fixture will not only increase the loading and unloading of the workpiece time, but also produce clamping error. Therefore, in the process should minimize the number of clamping.
The station is for completing certain process sections, each position occupied by the workpiece (or assembly unit) together with the movable part of the fixture or device relative to the stationary part of the tool or device after the workpiece has been mounted.

Step is in the processing of the surface and processing tools unchanged case, the continuous completion of that part of the process. A process can include several steps, there may be only one step. As long as the processing surface and processing tools change one, they should be counted as different work steps. For example, drilling, reaming and reaming the same hole should be taken as three steps. In the process card, according to the process of writing each processing step, it provides for a specific operation of the procedure and order.
For a number of identical workstations that are continuously carried out in a single fixture, it is usual to write a work step to simplify the process. Such as drilling 4-ф15, in order to improve efficiency, with a few tools or a composite tool at the same time processing a workpiece on several surfaces called composite steps, composite steps are also considered as a step. As shown in Figure 2-2, turret lathe with a turret for lateral movement to the car end face 2, 4 and with the turret mounted car wheel 1, 3 and the car hole 5, is the example of a composite step .
Cutting tools in the machining surface cutting, then cut to go one layer of material that a feed, a step can be a feed, you can also feed multiple times.
High-speed mold machine process card is a process as a unit, a brief description of the mold or zero, part of the process (or assembly) process a process file. The contents of the process card is relatively simple, but from the card can understand the parts of the process and processing programs.
Mold processing process is the mold factory (workshop) for technical equipment, production and guide the production of the organization, in accordance with the rules of production will be able to get qualified parts.
High-speed mold machine for a variety of metal molds, injection molds, alloy steel molds, graphite electrodes, precision parts, zippers, case, carburetor, shoe molds, seals, badges and other handicrafts and other machining semi-fine milling and fine Carving; can do plane, three-dimensional, relief carving and other processing; widely used in aviation, machinery, electronics, light industry and other industries. 【Suzhou Mold Casting】
