Manual precision surface grinder features:
●The workbench uses imported steel wire rope to drive the tabletop to move back and forth, with low noise and stable operation. The accuracy reaches 3u.
●The front and rear slideways of the Precision manual surface grinder adopt double V-shape, which can grind grooves and flange sides.
●The precision spindle uses a direct-connected V-3 low-vibration motor.
●The grinding head is manually advanced vertically, and the operation is convenient and controllable.
●The main castings are annealed and quarternized. The whole machine unit is rationally designed, extremely rigid and non-deformable, making it most suitable for super-hard molds and workpiece forming and grinding.
●The precision surface grinder has a beautiful appearance and a position for installing a digital display device is reserved on the machine tool.
When operating a manual surface grinder, we must pay attention to ensure that the oil circuit of the manual surface grinder is normal and reliable, so that it can run for a long time. For the operator, there are three major factors to master when operating a manual surface grinder:
1. The precise configuration of the grinding wheel of the precision manual surface grinder. Different grinding wheels are used for different workpiece materials. The grinding wheel is dressed with a sharp diamond pen. The speed of the carriage should be adjusted when dressing the grinding wheel. Only by achieving the sharpness of the dressing wheel can the workpiece be ground more smoothly.
2. Grinding machine hygiene. A manual surface grinder can be used for a long time if it is kept clean. This requirement is very important. It seems ordinary, but it requires perseverance. Just like people wearing neat clothes, a clean table and unobstructed oil circuits make people feel comfortable when operating the grinder. Cleanliness can keep the accuracy of the machine unchanged, and the accuracy can be maintained, so that the products can be high-precision!
3. Hand feel control. The hand feel depends on years of experience. Different masters operate the same manual surface grinder, and the workpieces coming into the grinder are different. Especially when grooving, fine grinding, and polishing products, you must be careful and take your time to produce fine work.
