Mold (Sprue hole)

Before
Tool

Round bar grindstone

Problem

Manual use of rod grindstone. It was necessary to form the tip of the grindstone to polish the tapered portion. Manual processing resulted in unstable polishing quality.

After
Tool

XEBEC Brush Crosshole (CH-A12-3M)

Results

Work efficiency improved because the shape of a brush fits to the tapered portion of a workpiece. Enables to remove cutter marks in a shorter time.
