How the profiling machine works

Profiling machine

Used for turning special-shaped curved surfaces. The template is made according to the shape and size of the special-shaped curved surface. During processing, the radial feed of the tool is used to make the roller close to the template by the spring or air pressure or hydraulic device, so as to turn the required outer circle shape.

• Introduction

If it is equipped with a machine tool loading and unloading device, the profiling machine tool can realize stand-alone automation or be included in an automatic production line. Some general-purpose machine tools can also achieve profiling after the profiling device is attached. The profiling movement can be divided into plane profiling and three-dimensional profiling. The machining accuracy of the profiling machine tool varies with the cutting amount, generally within the range of ±0.1 to ±0.03 mm, and the surface roughness is generally Ra5 to 1.25 microns.

• Development

In 1578, J. Besson of France used the profiling method to process wooden ornaments and threads for the first time. After that, machine tools for mechanical profiling appeared and were promoted in the 19th century. At the beginning of the 20th century, profiling machine tools with electromechanical servo systems appeared. In 1923, the production of electric contact copying milling machines began. In the 1930s, Switzerland, Germany and the United States successively produced hydraulic profiling devices, and then underwent a series of improvements.

• Working principle

1. First, place the metal workpiece to be processed on the machine table and fix it with a fixture.

2. Next, install the milling cutter on the machine tool spindle, and adjust the position and angle of the milling cutter for processing.

3. Before processing, the shape and size of the milling cutter need to be adjusted to match the shape and size of the workpiece to be processed.

4. When machining starts, the machine tool spindle starts to rotate, and the milling cutter cuts along the workpiece surface to a certain depth to achieve the desired shape and size.

5. During the machining process, both the machine tool spindle and the worktable can perform various movements in order to complete complex machining tasks.

6. After the processing is completed, the workpiece is removed from the machine tool, and the necessary follow-up processing is carried out, such as grinding, polishing, etc. In short, the automatic copy milling machine realizes the processing of metal workpieces by rotating the milling cutter and adjusting the position of the machine tool spindle and worktable, so as to achieve the required shape and size

• Classification

Profiling machine tools include profiling lathes, profiling milling machines and profiling planers. In addition, there are special profiling machine tools, such as blade profiling milling machines, mold profiling milling machines and propeller profiling milling machines. The profiling movement includes plane profiling and three-dimensional profiling, etc.

MXZ7203L automatic profiling router is controlled by single-chip microcomputer program, which can choose full-automatic/semi-automatic or manual operation; the rotation speed of the worktable can be controlled in sections by sensors; the cylinder is positioned in advance to ensure the accuracy of feeding, mainly For  peripheral profiling processing of circular, oval, rectangular and other shaped workpieces, such as bamboo and wood brushes, cup lids, knife handles, tableware, toys, etc.

By the 1950s, hydraulic profiling machine tools increased rapidly. After the 1970s, due to the rapid development of electronic technology and numerical control machine tools, copying machine tools gradually decreased. Profiling has certain limitations. For example, the radian of some parts of the workpiece is too small, and the tool cannot be processed. Now LDSWOODWORKINGMACHINE has developed and manufactured a CNC profiling router, which greatly increases the range of processed products, and can quickly convert processed products. As long as there are CAD graphics, the graphics can be imported into the equipment program through the USB interface, and the processing route can be automatically generated. The different radians of the surrounding shapes can be realized by changing the tool.
