The machining advantages of surface grinders and the usage of measuring tools

1、 The surface grinding machine has high precision and stable quality in machining parts. The positioning accuracy and repeatability of surface grinding are high, which makes it easy to ensure the consistency of part size. As long as the process design and program are reasonable, correct, and detailed, the accuracy and high precision of the parts can be guaranteed, and it is also easy to carry out quality control processes

Secondly, the automation level is high, which can reduce the physical labor intensity of the operator. For the program that is automatically inputted during the machining process, the operator needs to start the replacement of the tool, the electric discharge cutting machine, and the tool, load and unload the workpiece during the machining process, mainly by observing and monitoring the operation of the machine

3. Dimensional annotation should conform to the characteristics of grinding machine processing. In CNC programming, all points, lines, dimensions, and positions are based on the origin of programming. Therefore, provide the coordinate dimension directly or try using the same reference size

Fourth, Unified Geometric Type or Size

The shape of parts and chambers should adopt a unified geometric shape or size, which can reduce the number of tool changes and shorten the program length using control programs or special programs.

. The shape of the parts should be as symmetrical as possible, making it easy to use flat ground mirrors to program processing functions and save programming time

Fifth, reliable positioning reference

On a grinder, the machining process tends to be centralized, and using the same reference is very important.

. Facilitating the development and modification of new products. Grinding machine processing generally does not require many complex technologies and equipment. Through processing programs, complex shapes and high-precision parts can be processed. When the product is modified or the design is changed, as long as the program is changed, no design tools are needed. Therefore, grinding machines can greatly shorten the product development cycle, providing a quick way for the development of new products, product improvement, and product enhancement

Sixth, the development of manufacturing systems that can be upgraded

Abstract: Planar grinding machines and their processing technologies are the foundation of computer-aided manufacturing.

7. High production efficiency

Surface grinding processing can be clamped on multiple processing surfaces again, usually only tested first, so you can save a lot of intermediate processes during ordinary machine tool processing. Due to the stable processing quality of grinding machine parts, it brings convenience to subsequent processes and significantly improves overall efficiency.

Instructions for using flat grinding tools

Grinding machines are mainly used for grinding wheels around grinding wheels, cast iron, non-ferrous metals, and other materials.

. According to the material and shape of the workpiece, different clamping and positioning methods are used. A general plane can be machined by electromagnetic attraction or directly fixed on the workbench. The usage of flat grinding tools, including flat, right angle, arbitrary angle, and cylindrical end face, is briefly described

1. First, hold the required block gauges (generally, there are 1-3 block gauges for different sizes, except for special sizes where more than 3 block gauges are needed)

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

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

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

5. Return it promptly after use

2. Micrometer for flat grinding measuring tools

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

2. The usage range is ± 0.02mm, which means within the zero position, left ten grids, and right ten grids, the angle between the surface and the workpiece is tilted by 30 degrees

3. When checking the zero point, if the instrument is too small, the watch will crash to the right, and vice versa

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

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

3. Micrometer for flat grinding measuring tools

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

2. When measuring dimensions, first take the integer on the horizontal scale, which can be accurate to one decimal place, and then look at the vertical scale value. Use the zero scale as the standard and take the corresponding value

Fourth, the digital display of the flat grinding measuring tool in thousandths

Hold the ruler in your right hand, place your thumb, slide left and right, and clamp the cutting edge of the caliper on the workpiece to be measured (the cutting edge should be parallel to the workpiece surface, not tilted, and the displayed value on the screen is the measured size).
