rough griniding

Rough grinding is the good way to use grinding wheel to remove the most material from the hard part surface .Finally ,the machined part have rough shapes and roughness .

precision grinding

Precision grinding is a way to remove microns of materials to achieve a particular surface finish and tight roughness,It is one of the most important process before polishing the surface of part .

forming grinding

Forming grinding is one of the efficient grinding ways. Firstly,skilled workers grind by forming the grinding wheel with demanding shapes ,then grind the part to achieve the shapes requirements .The forming grinding is normally used for machining the tool steel with hardness .

polish grinding

Polishment after grinding is the final process of the whole machining process .The polished surface will be looked as a mirror .

What is the Surface Grinding

The grinding surface is one of the precision grinding options, It is used to remove the extra material on the workpiece surfaces and give the flat surface great finish and accuracy.
The surface grinder is mainly comprised of an abrasive wheel, a working holding device and a rotary table. The workpieces were fixed in the working holding table and grinded by the wheel。
Together with other grinding operations ,the surface grinding finish is decided by a wide range of factors ,such as wheels ,grinding materials ,feed rate ,wheel speed and worker’s experience .
In addition, the surface grinding works well with the tungsten carbide, tools steel, aluminum and so on.

The Benefits of Surface Grinding

  • 1

    High accuracy and quality stability

    Surface grinder has high positioning accuracy and repetition accuracy. In the surface grinding process ,the dimensional precision of the mass workpieces has good consistency. So it is convenient for quality control during processing.

  • 2

    High Degree of Automation

    The grinding service can be processed automatically according to the program, it will greatly save manpower and reduce machining mistakes.

  • 3

    Suitable for Flat, Radius and Grooving Grinding.

The Experience of Grinding the Steel with Little Thickness

How to make sure the high precision and great parallelism during grinding a very thin steel ?It’s a common problems for us .Let’s take an example .the part has 30mm long,20m wide and 1mm ,the parallelism should reach +/-0.002μm ,the accuracy should be +/-0.003μm .these kinds of parts are used to plug gauge. The following way is the better way from SUND TOOLS :

  1. We should make sure the raw material has no magnetism
  2. The fixture is ready. The minimum height of this fixture is 10mm, we should make there’s no magnetism when putting the part in the fixture, and the fixture should be bigger than the grinding part, then we’ll use block to fix the position of the grinding pats.
  3. When critical size is almost up to the target dimension, it is easy to scrap or out of dimension.so we suggest worker to mark the grinding surface with color pen, workers can process the grinding feeding according to the color.
