What are the types of grinding wheel?

2024-07-29

Common grinding process types can be divided into cylindrical grinding, surface grinding, internal grinding, forming grinding, high-speed grinding and high-efficiency grinding and so on.
1. Cylindrical grinding
Cylindrical grinding can be divided into central cylindrical grinding and centerless cylindrical grinding. The central cylindrical grinding of the workpiece around the fixed central axis rotation and positioning, and centerless cylindrical grinding of the workpiece rotation center is not fixed, by its own surface positioning. The drive of the centerless cylindrical grinding workpiece mainly depends on the friction between the workpiece and the pallet or the adjusting wheel.
During centerless grinding, the workpiece is positioned by the machined surface itself and is supported by a pallet between the grinding wheel and the guide wheel for grinding. The axis of the workpiece will be slightly higher than the center of the connection between the grinding wheel and the guide wheel.
2. Surface grinding
Grinding wheel surface grinding can be divided into horizontal spindle grinding wheel peripheral grinding and vertical spindle grinding wheel end face grinding two categories, and each fine class is divided into reciprocating table and rotary table two categories.
Rotary worktable can realize non-stop loading and unloading of workpiece, compact structure, smaller footprint, conducive to multi-grinding head layout, can achieve coarse and fine integrated processing. The rigidity of the vertical shaft grinding head is better and is suitable for heavy-duty grinding. The bowl-shaped grinding wheel or sand tile supported by the steel plate is commonly used as the grinding tool. Its coverage width is large, and it often does not require transverse feed movement, but only axial feed movement. It is often used for high-volume grinding with high flatness requirements.
The disadvantage is that heat dissipation and chip removal are not as easy as the horizontal spindle category. In industrial production, the horizontal spindle grinding wheel peripheral grinding table is usually used more reciprocating grinding.
3. Internal grinding
The common form of internal grinding process is the most widely used feed grinding. CENTELESS INTERNAL ROUND GRINDING OF THIN-WALLED SLEEVE OF DIFFEREST RIGIDITY. Among them, the high-speed rotation of the grinding wheel inside the workpiece is the main motion, and the low-speed rotation of the adjusting wheel of the empty sleeve drives the workpiece to rotate and make a circumferential feed motion. The roller of the empty sleeve will play an auxiliary supporting role.
4. Surface grinding
Grinding wheels are commonly used to grind curved surfaces by forming grinding, trajectory grinding and swell grinding.

Rotation direction of grinding wheel of grinding machine

2024-07-29

The direction of rotation of the grinding wheel of the grinder should be such that the debris flies downward away from the grinding wheel, which is usually counterclockwise. This arrangement ensures safety during operation and prevents wear debris or workpiece fragments from flying to the operator, thereby reducing the risk of accidents. In actual operation, it should be ensured that the rotation direction of the grinding wheel conforms to the safety regulations, and avoid standing in the opposite direction of the grinding wheel rotation to prevent fine particles from being ejected and ensure the safety of the operator.

Check the grinding wheel: Before use, carefully check the grinding wheel for cracks and confirm whether the installation is firm. Make sure that the grinding wheel has not suffered any damage and is installed correctly.

What is the grinding wheel used?

2024-07-29

Grinding wheel is a kind of tool used for grinding. It consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) by bonding agent, and has a certain strength of consolidated abrasives. The main components of the grinding wheel include abrasive, bond and pores, which are collectively referred to as the three elements of the fixed abrasive. There are many kinds of grinding wheels. According to the different binders, the common ones are ceramic (binder) grinding wheels, resin (binder) grinding wheels, rubber (binder) grinding wheels, etc. Grinding wheels are widely used and can be rotated at high speed for rough grinding, semi-fine grinding and fine grinding of metal or non-metal workpieces, as well as grooving and cutting operations. In industrial applications, grinding wheels can process the outer circle, inner circle, plane and various types of surfaces of the workpiece.
