Injection mold makers everywhere will almost always be looking for ways to enhance their operations. In whatever way you'll be able to shorten your delivery date and improve your quality must be seriously investigated.
Jig-grinding is almost always overlooked as being a meaningful machine tool for injection mold making. Yet, from my experience, it is a very valuable machine that gets the task done quickly and extremely accurately.
Exactly why is the jig-grinder overlooked?
It can be overlooked partly since the majority toolmakers view it being an out of date machine which reaches just best for round holes or frustrating contours that needs to be done on a CNC milling machine. It's true, it is not quite normal, it is primarily utilized for round holes, and it does master contours just like you will dsicover in the gauge for inspection.
That is why this is a ace in the hole for creating a plastic mold. Because it's so overlooked, so efficient therefore accurate, you should please take a second look as of this tool from the not so distant past. Some shops run their jig grinder all day every day, performing a selection of tasks.
How can the jig grinder save me time and money?
Some good samples of some time consuming tasks it may prosper:
Blind hole floors. These are generally always a problem to accomplish; either you mill them extra deep before heat treat and grind to match, or else you leave stock for post heat treatment machining. No matter what, it's a bother to obtain the depths directly in a prompt manner. Using the jig grinder, you depart them shallow before heat treat, and just use a CBN wheel to in a short time grind the depth perfectly. This is considerably quicker and simpler than hard milling or guessing in the depths when grinding.
Bosses and other details. Why EDM them when you can do it in a fraction of times?
Adding relief to cores and core pins. You may either utilize a Ded-Tru machine, or possibly a spin fixture on the surface grinder, or hard turn your cores. You can also do high of the project with a jig grinder.
Ejector and core pin holes. While nearly all knock out holes are WEDMd these days, there are still applications when it is smart to jig grind them.
Pockets, whether round, square or rectangular. It's irresistible a jig ground pocket. A great application for locators within the core and cavity blocks. This way you're assured of perfect alignment.
