Checking for Positive DraftOn occasion tool marks can be so deep that they reduce the draft or the polisher accidentally takes off the draft. The key is to always check for positive draft by putting a six-inch scale on the wall and comparing the angle it makes to the parting line. It takes just a [...]
One of the most difficult jobs for any polisher is getting a high diamond finish on aluminum. Achieving a good shine in soft gummy material that constantly clogs stones and easily takes deep scratches from sandpaper is enough to challenge anyone. Brushing and buffing can easily lead to grooves and lines in the finished surface [...]
If you think of texturing as the paint on a finished car, you can then draw the comparison that the paint job is only as good as the bodywork beneath the paint. And so, texturing can be optimized by the quality of the surface to be textured. […]
When choosing plating for your mold or mold components, you must first identify the problem to be solved or the problem to be prevented. […]
The origin of mold design and moldmaking in China is traceable to metal stamping die makers, rubber moldmakers and die cast die makers. […]
the CAD/CAM system is another equally important component. Today’s CAD/CAM systems have greatly advanced over the years, […]
Continuing within the circle, tool-holders play an important role in hard milling. Because hard milling requires a large range of rpms-from low rpms for a roughing application to high rpm for HSM-only the HSK interface between the toolholder and spindle interface should be used. […]
What was once considered a black magic has become a more calculable science. Still, many variables affect the clamping force of a magnet. Some of these variables include: material composition, surface finish, contact area, vibration and cutting forces. […]
The graphite industry is constantly striving to produce higher quality grades. Graphite materials have continued to evolve along with the other aspects of the EDM industry, […]
two new types of milling magnets entered the market – magnetic setup blocks and permanent milling magnets. […]
