Embodiment 1

[0029] A back milling method, the specific steps are as follows:

[0030] Step 1. Clean the worktable and flat-nose pliers to ensure that there are no chips on the worktable and fixtures that affect the machining accuracy;

[0031] Step 2. Install the reverse milling tool on the main shaft of the milling machine first, and then correct the head of the milling machine to prevent the machine head from being tilted and cause the surface of the workpiece to be uneven after processing. Preferably, the milling machine adopts an XS5040 vertical milling machine, and can also use For other types of milling machines, as long as they meet the requirements for reverse milling, this application does not limit this;

[0032] Step 3. Adjust the speed of the milling machine and control it at 950r / min;

[0033] Step 4. Clamp the used fixture on the worktable of the milling machine, make the clamp firm, and then clean it again to ensure that there are no chips on the worktable and the fixture....

Embodiment 2

[0040] Step 1. Clean the worktable and flat-nose pliers to ensure that there are no chips on the worktable and fixtures that affect the machining accuracy;

[0041] Step 2. Install the reverse milling tool on the main shaft of the milling machine first, and then correct the head of the milling machine to prevent the machine head from being tilted and cause the surface of the workpiece to be uneven after processing. Preferably, the milling machine adopts an XS5040 vertical milling machine, and can also use For other types of milling machines, as long as they meet the requirements for reverse milling, this application does not limit this;

[0042] Step 3. Adjust the speed of the milling machine and control it at 1180r / min;

[0043] Step 4. Clamp the used fixture on the worktable of the milling machine, make the clamp firm, and then clean it again to ensure that there are no chips on the worktable and the fixture. Preferably, the fixture uses flat pliers. When clamping workpiece...

Embodiment 3

[0050] Step 1. Clean the worktable and flat-nose pliers to ensure that there are no chips on the worktable and fixtures that affect the machining accuracy;

[0051] Step 2. Install the reverse milling tool on the main shaft of the milling machine first, and then correct the head of the milling machine to prevent the machine head from being tilted and cause the surface of the workpiece to be uneven after processing. Preferably, the milling machine adopts an XS5040 vertical milling machine, and can also use For other types of milling machines, as long as they meet the requirements for reverse milling, this application does not limit this;

[0052] Step 3. Adjust the speed of the milling machine and control it at 1500r / min;

[0053]Step 4. Clamp the used fixture on the worktable of the milling machine, make the clamp firm, and then clean it again to ensure that there are no chips on the worktable and the fixture. Preferably, the fixture uses flat pliers. When clamping workpieces...

Abstract

The invention discloses a reverse milling machining method. The reverse milling machining method comprises the following steps that firstly, a worktable top and flat tongs are cleaned; secondly, a reverse milling tool is arranged on a main shaft of a milling machine, and then a machine head of the milling machine is corrected; thirdly, the rotation speed of the milling machine is adjusted and is controlled to range from 950 r / min to 3,000 r / min; fourthly, an adopted clamp is clamped to the worktable top of the milling machine; fifthly, a tool piece needing to be machined is fixed to the clamp;sixthly, the highest point and the lowest point are found on the surface of the tool piece needing to be machined, and flat milling is conducted with the lowest point; seventhly, rough edges and burrs are removed, a machined plane serves as a bottom face, and reverse milling is conducted; eighthly, the machined plane is clamped to the clamp, and the tool piece needing to be machined is milled inplace in the width direction; and ninthly, the machined tool piece is subjected to surface polishing. According to the reverse milling machining method, design is novel, the work efficiency is improved, rough material hexagon forming fine machining is achieved, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of workpiece processing, in particular to a back milling processing method. Background technique [0002] Machine tool (English name: machine tool) refers to a machine that manufactures a machine, also known as a machine tool or machine tool, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. [0003] Milling is a high-efficiency machining method that uses a rotating multi-blade tool to cut a workpiece. When working, the tool rotates (for the main movement), the workpiece moves (for the fee...
