Industrial Grinding Machine

Grinding machine

Lapping machine is a grinding machine that grinds the workpiece surface with a grinding tool coated or embedded with abrasive material. It is mainly used for grinding high precision plane, inner and outer cylinder surface, conical surface, sphere, thread surface and other surface. The main types of grinding machines are disc grinding machines, rotary shaft grinding machines and various special grinding machines. The grinding machine control system takes PLC as the control core, and the text display is the control mode of man-machine dialogue interface. Man-machine dialogue interface can talk with people about equipment maintenance, operation, failure and other information; Operation interface is intuitive and convenient, program control, simple operation. All-round safety considerations, abnormal state misoperation invalid. Real-time monitoring, fault, error alarm, easy maintenance.

A grinder that grinds the surface of a workpiece with a tool coated or embedded with abrasive material. It is mainly used for grinding high precision plane, inner and outer cylinder surface, conical surface, sphere, thread surface and other surface.

Features:

Grinding is an important machining method in ultra-precision machining, which has the advantages of high machining accuracy and a wide range of processing materials.

The main types of grinding machines are disc grinding machines, rotary shaft grinding machines and various special grinding machines.

Disc grinding machine

It is divided into two kinds of single disc and double disc, and the double disc grinding machine is the most common application. On a double disc grinder (see figure [Double disc Grinder]), multiple workpieces are simultaneously placed in cages located between the upper and lower grinding disks, and the cages and workpieces move in parallel plane driven by eccentric or planetary mechanisms. The lower grinding disk can rotate parallel to the upper grinding disk without turning or against the lower grinding disk, and can move up and down to compress the workpiece (the pressure is adjustable). In addition, the grinding plate can also rotate an Angle around the column with the rocker arm in order to load the work parts. Double disc grinding machine is mainly used to process two parallel surfaces, one plane (need to add pressing workpiece accessories), cylindrical surface and spherical surface (using V-groove grinding disc). When machining the outer cylinder surface, because the workpiece should slide and roll, it is necessary to choose the cage hole groove type and arrangement Angle reasonably. Single disc grinding machine has only one lower grinding disc, used for grinding the lower plane of the workpiece, can make the workpiece of different shapes and sizes of the same plate processing, grinding accuracy is high. Some grinders also have mechanisms that automatically correct the grinding disc during the grinding process.

Rotary shaft grinding machine

The workpiece or grinding tool (adjustable grinding ring or grinding rod) is driven by the spindle with positive and reverse rotation. The structure is relatively simple, and it is used for grinding the inner and outer cylindrical surface.

Special purpose grinding machine

According to the different grinding workpiece, there are center hole grinding machine, steel ball grinding machine and gear grinding machine. In addition, there is a centerless grinding machine, which uses a similar principle of centerless grinding, for grinding cylindrical workpiece.

Three roller grinding machine

Main application and characteristics: three roll grinding machine is widely used in paints, coatings, dye, printing ink, plastic, leather, rubber, lead, medicine, food, cosmetics, and insulation materials and other chemical industry raw materials of wet grinding machine, the machine has shattered, scattering, emulsion, homogeneous, toning, multiple functions such as recycling waste materials, It is widely used in scientific research, testing, formulation and microdebugging production of crushing.

The main parts of this machine are three rolls, using Cr12 steel for strengthening protection treatment, anti-wear hardness of HRC52°-58°, surface rough hardness of 0.2-0.1, the machine is easy to operate, easy to change color, beautiful appearance, low noise, preferential price, used for all kinds of materials research and hone.

Structural components: The machine is mainly composed of (1) body (2) electrical switch (3) discharge board (4) roll (5) baffle board (6) adjustment system (7) transmission system (8) motor. It consists of eight components.

Working principle: the raw materials by the two rollers and two pieces of gear plate composed of natural hopper to join, after, in the two groups of asynchronous rotation, the opposite of a sharp turn raw material, cut, between raw material molecular structure stress surface grinding, then through, even before the roller in the high speed of the secondary grinding, thus achieve high-speed uniform mixing of various kinds of raw materials.

Automatic grinding machine

1, automatic grinding machine for high-speed grinding machine, precision grinding machine. Emery cloth belt is adopted, the electric appliance adopts Japan Hequan, Fuji, machine spray, the color is microcomputer color.

2. Guide rail is Taiwan linear guide rail.

4. This automatic grinder, high-speed grinder, precision grinder can be used for mechanical scraper and manual scraper grinding.

5, special grinding wheel design, grinding cloth belt no pressure, scraping no deformation, no ripple phenomenon, to ensure grinding accuracy.

6, grinding Angle to match the efficiency of various special printing.

7. The grinding machine is equipped with dust cleaning device, which can reduce industrial pollution and is conducive to the health of staff and the maintenance of equipment.

8, automatic grinding machine, high-speed grinding machine, precision grinding machine is easy to operate, no professional technology can be operated.

Notes to note:

Mill in thermal power plant were widely used in the coal pulverizing system, but its transmission shaft vibration and little rock broken teeth has been plagued by system of safety in production, I plant the coal pulverizing system before one period is under these two defects, even affected the unit fuel supply, the maintenance staff adjustment for many times, the effect significantly, the shaft vibration is lower than 0.08 mm.

Specific measures:

1. Top gear clearance is one of the important assembly parameters of gear transmission device. It is stipulated in the regulations that the gap between large and small teeth is 7.5-8.5mm. In the actual adjustment process, the tooth top clearance should be adjusted to 8.5-10mm to reduce the impact caused by the tooth top clearance, resulting in tooth overload and fracture.

2. The insufficient tightening force of the large gear ring is also one of the important reasons for its deformation. In practice, in addition to increasing the bolt tightening force, 10mm thick steel plate will be used to connect the joint surface of the large gear ring, increase the fastening surface, prevent the deformation of the gear ring, ensure that the angular velocity of the master and slave wheels is consistent, prevent the inertia force caused by the change of transmission ratio, resulting in fatigue fracture.

3, full of drive shaft bearing lubrication is also ensure the smooth running of the main reasons, the traditional manual of regular, come on, although the move will also be able to ensure adequate lubrication, but easy to cause excessive or insufficient, the amount of lubricating oil recommended mechanical timing, quantitative add grease scientifically, so as to ensure the appropriate lubrication of bearings, reducing vibration, Avoid bearing wear and cage rupture, prolong life.
