Processing advantages of surface grinding machine and use method of measuring tools

1、 High precision and stable quality of machined parts

The surface grinding has high positioning accuracy and repetition accuracy, which is easy to ensure the consistency of the size of the parts. As long as the process design and procedures are reasonable, correct and detailed, the accuracy and high accuracy of the parts can be ensured, and the quality control process can also be carried out.

2、 High degree of automation, which can reduce the manual labor intensity of the operator

For the program automatically input in the machining process, the operator needs to start the replacement of tools, EDM machine tools and tools, load and unload workpieces during the machining process, mainly to observe and monitor the operation of the machine.

3、 The dimension shall conform to the characteristics of grinding machine processing

In numerical control programming, all points, lines and positions are based on the origin of programming. Therefore, it is better to give the coordinate dimension directly, or try to use the same reference size.

4、 Uniform geometric type or size

The shape of the parts and the inner chamber should preferably adopt a uniform geometry or size, so as to reduce the number of tool replacement, and the control program or special program can also be used to shorten the length of the program. The shape of the parts should be as symmetrical as possible, so that it is easy to program the processing function using the mirror surface of plane grinding to save the programming time.

5、 Reliable positioning datum

On the grinding machine, the machining process tends to be centralized, and it is very important to use the same datum. Facilitate the development and modification of new products. Generally, the mill processing does not require many complex technologies and equipment. The complex shape and high-precision parts can be processed through the processing program. When the product is modified and the design is changed, as long as the program is changed, no design tool is required. Therefore, the grinding machine can greatly shorten the product development cycle and provide a fast way for the development of new products, product improvement and product improvement.

6、 It can be developed to a more advanced manufacturing system

Plane mill and its processing technology are the basis of computer aided manufacturing.

7、 High production efficiency

The surface grinding process can be clamped on multiple processed surfaces again, and usually only tested first, so that you can save many intermediate processes during the processing of ordinary machine tools. Because the processing quality of grinding machine parts is stable, it brings convenience to subsequent processes, and the comprehensive efficiency is significantly improved.

Usage of surface grinding measuring tools

The grinding machine is mainly used for grinding the grinding wheel around the grinding wheel, cast iron, non-ferrous metals and other materials. Different clamping and positioning methods are adopted according to the material and shape of the workpiece. The general plane can be processed by electromagnetic suction or directly fixed on the workbench. Plane, right angle, arbitrary angle, cylindrical end face, etc. the use of surface grinding tools is briefly described.

1. First, take the required block gauges (the number of block gauges for general size is 1-3, except for more than 3 for special size).

2. Compare the loss of the block gauge on the tolerance table.

3. Clean the two smooth surfaces of the block gauge, and then force the two block gauges together, first in the shape of a cross, then rotate them into parallel, and stick them together. When sticking, stick the words on the outside.

4. The selected block gauge value shall be very close to the measured size, within 0.005 μ Within.

5. Return it in time after use.

2、 Dial indicator of surface grinding measuring tool

1. The scale of each small grid is 0.002mm.

2. The most accurate range of use is ± 0.02mm, that is, in the zero position, the left ten grid and the right ten grid, the included angle between the table and the vertical surface of the workpiece is inclined by 30.

3. When checking the zero point, if the meter is small, the watch will hit the right, and vice versa.

4. The dial on the watch can be rotated to correct the zero point.

5. The heads of the hands are 0.4 mm and 1.0 mm, which can be selected with 0.4 mm. These steps are less than 1. 00 mm, less than 1. The slope of a 10 mm pointer is greater than 1. 0 mm.

3、 Micrometer of surface grinding measuring tool

1. The horizontal scale of the micrometer is 0.5mm and the vertical scale is 0.01mm.

2. When measuring the size, first take the horizontal scale integer, which can be accurate to one place after the decimal point, and then look at the vertical scale value. The zero scale shall prevail, and take the corresponding value.

4、 Number of surface grinding measuring tools (thousands)

Hold the ruler with your right hand, slide it at the position of your thumb, and clamp the cutting edge of the caliper on the workpiece to be measured. (the cutting edge should be parallel to the workpiece surface, and cannot be placed obliquely. Then the value displayed on the display screen is the measured size.
