What is a real high precision centerless grinder?

High-precision centerless grinding machine, which should be considered from different angles:

1.The accuracy of the machine tool parts, which is related to the processing equipment. Only high-precision parts can be assembled into precision centerless grinding machines.

2.Accurate assembly accuracy requires perfect assembly technology and skilled assembly technicians.

3.materials and their heat treatment. The proportion of the composition of the centerless grinding machine casting is important, and the proportion of the copper alloy must be accurate. Castings must be heat-treated and aged.

4.The running surface of the casting must be scraped. Otherwise, the positioning accuracy will not be accurate.

5.The structure and design of the machine tool should be scientific.

6.The real precision centerless grinding machine must be equipped with a CNC system and a grating ruler to ensure accurate feeding.

7.CNC CNC centerless grinding machine is usually exponentially controlled centerless cylindrical grinder, the workpiece is not centered and supported, but placed between the grinding wheel and the guide wheel, and the grinding machine that grinds the rotating surface of the workpiece by centerless grinding method is supported by a supporting plate and a guide wheel. The grinding accuracy of the centerless grinder is generally:

The roundness is 1-2 microns, the dimensional accuracy is 1-3 microns, and the high-precision centerless grinding machine can reach microns and 2 microns respectively. CNC Centerless Grinder Number; Model HFC-1808CNC, HFC: stands for brand number, 18 stands for:

The grinding wheel size is 18 inches, and 08 represents the grinding wheel width of 8 inches.

Answer: The parts and components used in precision grinding machines are imported, and ordinary grinding machines refer to high-precision grinding machines with high precision and low-end grinding machines.

1. Centerless grinding machine: It is a kind of grinding machine that does not need to use the axis positioning of the workpiece for grinding.

2. Grinding machine: It is a machine tool that uses abrasive tools to grind the surface of the workpiece.

Second, the way is different.

1. Centerless grinding machine: mainly composed of three mechanisms of grinding grinding wheel, adjusting wheel and workpiece support, wherein the grinding grinding wheel is actually responsible for grinding work, adjusting wheel controls the rotation of the workpiece, and controls the feed speed of the workpiece, as for the workpiece support is to support the workpiece during grinding, these three kinds of parts can have several ways to match.

2. Grinding machine: The grinding machine can process materials with high degree of hard burial, such as hardened steel, cemented carbide, etc.; It can also process brittle materials, such as glass and granite. The grinding machine can be used for high-precision grinding with little surface roughness, as well as high-efficiency grinding, bending cavities such as powerful grinding, etc.

Third, the processing method is different.

1. Centerless grinder: through-type, cut-in type and cut-in one-pass type, through-type centerless grinding. The workpiece is fed along the axis of the grinding wheel for grinding.

Adjust the slight inclination angle of the guide wheel axis to achieve axial feed of the workpiece. It is suitable for grinding slender cylindrical workpieces. Stub shafts without center holes and sleeved workpieces, etc.

2. Grinding machine: the grinding wheel with high-speed rotation is used for grinding processing, and a few are processed by using other abrasives such as oil stones, abrasive belts and free abrasives, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machines.

Dear users, the reason for the large middle of the product may be due to the fact that the precision centerless grinder grinds out the middle of the product in the following aspects: 1The wear of the grinding tool is uneven.

If the grinding tool is worn unevenly, it will cause the middle of the ground product to be large, because the uneven wear of the grinding tool will cause the diameter of the ground product to be uneven. 2.The stiffness of the machine tool is insufficient.

If the stiffness of the machine tool is insufficient, it will cause the middle of the grinding product to be large, because the insufficient stiffness of the machine tool will cause the diameter of the ground product to be unstable. 3.The temperature during the grinding process is too high.

If the temperature during the grinding process is too high, it will cause the middle of the ground product to be large, because the macro belt temperature is too high, which will cause the diameter of the ground product to expand. 4.Improper selection of grinding tools.

If the grinding tool is not selected properly, it will lead to a large middle of the grinding product, because the improper selection of the grinding tool will lead to the instability of the diameter of the ground product. The above is the reason why the middle of the product may be large due to the direct grinding of the precision centerless grinder, which needs to be analyzed on a case-by-case basis.

Centerless grinding machine refers to the workpiece is clamped without core, generally supported between the guide wheel and the supporting frame, and the workpiece is driven to rotate by the guide wheel, which is mainly used for grinding cylindrical surfaces.

A centerless grinder is a type of grinding machine that does not require the use of a workpiece shaft for grinding. The grinding wheel, the adjusting wheel and the workpiece bracket are composed of three mechanisms, in which the grinding wheel actually carries out grinding processing, the adjusting wheel controls the rotation of the workpiece, produces the workpiece feed rate, and the workpiece gripper is ground.

There are three ways to support the workpiece, and the principle is the same except for stopping the grinding.

Centerless grinding machine manufacturers are introduced as follows:

1. Yuhuan Jianghuan machine tool****

All belong to cylindrical grinding machines.

1. Ordinary cylindrical grinding machine, positioned by the center hole, can grind the step shaft, and the efficiency is lower than that of the centerless grinding machine.

2. The centerless grinding machine is not positioned with the center hole, and the step shaft cannot be grinded, which has high efficiency and saves the process of punching the center hole.

Centerless grinding machine is a kind of cylindrical grinding, which is an efficient equipment for mass production grinding of equal diameter cylindrical.

Centerless grinding machine is just a classification of grinding machines, grinding machines are machine tools that use abrasive tools to grind the surface of a workpiece.

Centerless grinding machine is a kind of grinding machine that does not need to adopt the axis positioning of the workpiece and grinding, mainly composed of three mechanisms of grinding grinding wheel, adjusting wheel and workpiece support, wherein grinding grinding wheel is actually responsible for grinding work, adjusting wheel controls the rotation of workpiece, and controls the feed speed of workpiece, as for workpiece support is to support workpiece during grinding, these three kinds of parts can have several ways to match, except for stopping grinding, the principle is the same.
