Injection mold makers everywhere are invariably researching to improve their operations. In whatever way you'll be able to shorten your delivery date and enhance your quality needs to be seriously investigated.
Jig-grinding is almost always overlooked being a meaningful machine tool for injection mold making. Yet, from my experience, it's a very valuable machine that will get the work done quickly and very accurately.
How come the jig-grinder overlooked?
It's overlooked partly since most toolmakers consider it as a possible outdated machine measuring only great for round holes or frustrating contours that needs to be done over a CNC milling machine. It is true, it's not common, it's primarily employed for round holes, and yes it does excel at contours just like you will spot in a gauge for inspection.
This is the reason it is a secret weapon for creating a plastic mold. Which is so overlooked, so efficient therefore accurate, you ought to please take a re-assessment as of this tool of the not distant past. Some shops run their jig grinder all day every day, performing a selection of tasks.
Just how can the jig grinder save me time and expense?
Some really good instances of enough time consuming tasks it could flourish:
Blind hole floors. These are always a pain to do; either you mill them extra deep before heat treat and grind to match, or else you leave stock for post heat treatment machining. Either way, it is a bother to find the depths in a timely manner. Together with the jig grinder, you allow them shallow before heat treat, and merely utilize a CBN wheel to quickly grind the depth perfectly. This really is faster and much easier than hard milling or guessing in the depths when grinding.
Bosses and other details. Why EDM them when you are able get it done in the fraction of times?
Adding relief to cores and core pins. Either make use of a Ded-Tru machine, or a spin fixture over a surface grinder, or hard turn your cores. Additionally, you can do a lot of the work on a jig grinder.
Ejector and core pin holes. While virtually all knock out holes are WEDMd these days, you may still find applications when it makes sense to jig grind them.
Pockets, whether round, square or rectangular. It can be unequalled a jig ground pocket. A great application for locators within the core and cavity blocks. In this way you might be assured of perfect alignment.
