Q&A:

1.Can this file process molds?

Answer: This file can process high hardness steel above 55-60 degrees, such as hard alloy and quenched steel parts.

2. Is it suitable for filing jade?

Answer: Yes, this file can process non-metallic products with higher hardness and brittleness, such as ceramics, glass, jewelry, and jade.

3. May I ask how to choose the file grit?

Answer: The thickness of the file is selected based on the size of the machining allowance, machining accuracy, and material properties of the workpiece. Rough file cutter is suitable for workpieces with large machining allowance, low dimensional accuracy, large positional tolerance, and large surface roughness values; On the contrary, a fine-grained file should be selected, with 140 # being coarse and 600 # being fine. The larger the # number, the finer the particle size.

4.How to choose the size of the file?

Answer: The size specifications of the file should be selected based on the size and machining allowance of the workpiece being processed. When the machining size and allowance are large, a large-sized file should be selected, and vice versa, a small-sized file should be selected.

5.How to choose the shape of the file?

Answer: The shape of the file should be selected based on the shape of the part being filed, so that the shapes of the two are compatible. When filing the inner circular arc surface, a semi circular file or a circular file (small diameter workpiece) should be selected; When filing the inner corner surface, choose a triangular file; When filing the inner right angle surface, flat files or square files can be used.
