Die high-speed milling technology for processing the key technology

1) tool system;

Tool system is the structure constitutes a tool of the system, which mainly refers to tool material, tool and toolholder. Tool material has high hardness and wear resistance, good strength and toughness, good heat resistance and technics. At present, high-speed milling tool materials used in the main diamond, cubic nitride studio, ceramic cutting tools, carbide cutting tools, such as cutting tools and coatings.

The main tool is the overall structure and set of two teeth. Inlaid teeth mainly machine tool folder institutions, high-speed milling cutter role as a result of centrifugal force, this will result in destruction and blade clamping bodies off, so clamping cutter body must have a high strength, fracture toughness and rigidity to ensure the safe and reliable .

Handle system in the high-speed milling, the main settlement of less than rigid, repetitive precision of instability, the effects of centrifugal force, handle issues such as inconvenient for rapid tool change.

2) machine tool system;

Machine system is a means to achieve high-speed milling elements of the structure of security system, mainly to ensure that high-speed cutting speed, high-speed spindle system and access to accurate feedrate rapid feeding system.

High-speed spindle system is one of the keys to high-speed milling. High-speed spindle system should have sufficient rigidity and high precision rotary; light weight, compact structure, small inertia; good thermal stability; vibration and noise; good cooling and lubrication system.

3) Die CAD / CAE / CAM software system;

Model (CAD), analysis (CAE) and manufacturing (CAM) software system for the process must be able to receive from other systems and process data from these data, it is necessary to have a consistent, standardized interface. At present, the most commonly used mold interface standard is IGES (original graphics exchange standard). The key to high-speed milling CAD / CAM programming devices used to automatically adjust the best machine tool processing.

4) CNC control system.

CNC control system security should have the fast data processing capabilities and higher functional characteristics, in order to ensure high-speed cutting has a good processing performance. High-speed milling mold on the request of CNC control systems are mainly the following points: (1) a good feed control; (2) program segment short cycle time; (3) high interpolation accuracy, in order to ensure high-speed under the interpolation accuracy, should be the number of feed-forward and ahead of pre-processing program segment, in addition, can also be the use of non-uniform rational B-spline interpolation, to accelerate the return to red, smooth interpolation, speed up, such as bell-shaped contour control technologies; (4 ) interface data-processing networks, in order to shorten the data processing time, CNC controller must pass the "Ethernet" net direct delivery procedure.

The mould mills) cutter system of key technology of paring technological processing at a high speed; The cutter system refers to forming systematic structure of the cutter, among them mainly refer to the cutter material, cutter structure and one one hundred sheets of handles. The cutter material has higher hardness, wearability, good intensity, toughness, good heat resistance and craft. At present, milling the cutter material used while paring at a high speed mainly has diamond, cubic nitrogen canopy, ceramic cutter, hard alloy cutter and coating cutter,etc.. The cutter structure is mainly the whole and inlays two kinds of teeth. Inlay the tooth cutter main adoption machine and insert the organization, mill and pare the cutter because of the function of the centrifugal force at a high speed, will cause and clamp the organization to destroy and get rid of the blade, so a one hundred sheets of body must have higher intensity, fracture toughness and rigidity to clamp the organization, it is safe and reliable to guarantee. One hundred sheetses of handle system while mills and pares at a high speed, solve rigidity insufficient, if unstable centrifugal to repeat precision mainly. 2)Lathe system; Lathe system mean realize at a high speed milling structure to sharpen the key element ensuring the system, guarantee cut high-speed main shaft system of speed and win stock to the stocking to the system fast of the speed accurately at a high speed mainly. The high-speed main shaft system is the key to milling and paring at a high speed. The high-speed main shaft system should have enough rigidity and high gyration precision; Light, compact, inertia is small; Good heat stability; Vibration and noise are little; Good cooling and lubricating system. 3)Mould CAD/CAE/CAM software system; The model constructs (CAD), analyze and (CAE) make (CAM) course software system must can accept from other data that system come and deal with data these, so there must be unanimous, standardized int
