One Of The Secret Weapons In Injection Mold Making
Injection mold makers everywhere are invariably looking for ways to improve their operations.
However you can shorten your delivery date and boost your quality must be seriously investigated.
Jig-grinding is actually always overlooked like a meaningful machine tool for injection mold making.
Yet, from my experience, it is a very valuable machine which gets the job done quickly and
Exactly why is the jig-grinder overlooked?
It's overlooked partly since the majority of toolmakers view it being an old machine that's only
best for round holes or frustrating contours that needs to be done with a CNC milling machine. It is
true, it's not at all quite typical, it is primarily used for round holes, and yes it does master
contours just like you will discover inside a gauge for inspection.
That is why it is a ace in the hole for building a plastic mold. Which is so overlooked, so efficient
therefore accurate, you should have a re-evaluation only at that tool with the less than distant
past. Some shops run their jig grinder all day every day, carrying out a various tasks.
How can the jig grinder save me time and cash?
Good quality samples of some time consuming tasks it may do well:
Blind hole floors. These are generally always a pain to perform; either you mill them extra deep
before heat treat and grind to fit, or else you leave stock for post heat treatment machining. No
matter what, it is just a bother to find the depths directly in a timely manner. Using the jig grinder,
you allow them shallow before heat treat, and just use a CBN wheel to very quickly grind the
depth perfectly. This is faster and easier than hard milling or guessing in the depths when grinding.
Bosses and similar details. Why EDM them when it's possible to undertake it inside a fraction of
Adding relief to cores and core pins. You can either use a Ded-Tru machine, or a spin fixture on a
surface grinder, or hard turn your cores. Additionally, you can do much of the project over a jig
Ejector and core pin holes. While nearly all eliminate holes are WEDMd these days, you can still
find applications when it is smart to jig grind them.
Pockets, whether round, square or rectangular. It's hard to beat a jig ground pocket. A great
application for locators in the core and cavity blocks. Using this method you might be assured of
