Abstract
The invention provides a method for cutting a tungsten nickel iron alloy device with a slow speed wire, relating to a method for linearly cutting a tungsten nickel iron alloy plate so as to obtain high precision. The method is characterized of comprising the steps of: firstly clamping the tungsten nickel iron alloy plate on an electric spark small hole machine in the process of cutting; locating awire-penetrating hole for cutting an inner groove; piling up the tungsten nickel iron alloy plate; and clamping the tungsten nickel iron alloy plate on a slow speed wire machine table to be cut. Themethod piles up the tungsten nickel iron alloy plate to have a certain depth, increase the rigid of the plate, improve the cutting efficiency, guarantee an effect for conducting heat energy generatedby the electric spark in the process of wire cutting, and meet the precision machining requirement of the device.
Description
Technical field
A kind of method of cutting tungsten nickel iron alloy device with slow speed wire relates to and a kind of tungsten nickel iron alloy sheet material is carried out the line cutting processing, thereby obtains high-precision method.
Background technology
Tungsten nickel iron alloy device is usually used on the Medical CT machine as critical component, its external form is the strip sheet material that has many narrow grooves of processing, its depth of parallelism to inside groove requires less than 0.01mm, to the processing dimension tolerance between 0.02～0.05mm, flatness is required in 0.10mm, roughness to machined surface requires less than 1.6 μ m, thickness of detector is generally between 1.5～2.5mm, general processing method is difficult to reach high-precision requirement, and the tungsten ferronickel closes the sheet alloy clamping and the location is relatively more difficult, must find a kind of suitable clamping method and processing method.Originally many employing laser and numerically-controlled precise method for processing prepare, and not only working (machining) efficiency is low, and yield rate does not guarantee.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists on the above-mentioned prior art, provides a kind of and can effectively satisfy machining accuracy and roughness requirement, and the tungsten nickel iron alloy device flatness is good, the method method of the cutting tungsten nickel iron alloy device with slow speed wire that working (machining) efficiency is high.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of cutting tungsten nickel iron alloy device with slow speed wire, it is characterized in that its cutting process be earlier with tungsten nickel iron alloy sheet material clamping on the electric spark small hole machine, the location processes the used wire hole of cutting inside groove, then tungsten ferronickel sheet material is piled up, refilled to be clipped on the board of being careful and cut.
The method of a kind of cutting tungsten nickel iron alloy device with slow speed wire of the present invention is characterized in that its cutting process takes the method for repeatedly cutting, and adopts main cutting once, repaiies the method for cutting again.
The method of a kind of cutting tungsten nickel iron alloy device with slow speed wire of the present invention is characterized in that it is 3-8mm that its tungsten nickel iron alloy sheet material is piled up thickness.
Method of the present invention is piled up certain thickness with tungsten ferronickel sheet material, has increased the rigidity of sheet material, has improved cutting efficiency, has guaranteed the conducting effect of electric spark generation heat in the line cutting process, has satisfied the requirement on machining accuracy of device.
The specific embodiment
Plant the method for cutting tungsten nickel iron alloy device with slow speed wire, its clamping is characterised in that earlier that with clamping workpiece the wire hole location processing that inner chamber is used is piled up thickness less than the 8mm workpiece with tungsten ferronickel sheet material on the electric spark small hole machine, clamping cuts on a cutting machine of being careful.
Embodiment 1
To be of a size of 1.5 * 75 * 255mm tungsten nickel iron alloy sheet material clamping on the electric spark small hole machine, with dial gauge with one of them true edge centering, according to the relation of the position between the wire hole wire hole is processed, then 5 tungsten ferronickel sheet materials of having accomplished fluently wire hole are piled up into the workpiece that thickness is 8mm, clamping on a board of being careful, with dial gauge to the benchmark centering above the workpiece, cut inner chamber earlier, main cutting once repaiied and cut once, and last leapfrog comes out profile is once cut.Machining accuracy and roughness meet the requirements, and the tungsten nickel iron alloy device flatness is good.
Embodiment 2
To be of a size of 1.5 * 75 * 255mm tungsten nickel iron alloy sheet material clamping on the electric spark small hole machine, with dial gauge with one of them true edge centering, according to the relation of the position between the wire hole wire hole is processed, then 2 tungsten ferronickel sheet materials of having accomplished fluently wire hole are piled up into the workpiece that thickness is 3mm, clamping on a board of being careful, with dial gauge to the benchmark centering above the workpiece, cut inner chamber earlier, main cutting once repaiied and cut once, and last leapfrog comes out profile is once cut.Machining accuracy and roughness meet the requirements, and the tungsten nickel iron alloy device flatness is good.
