Injection mold makers everywhere will almost always be searching for ways to enhance their operations. However you can shorten your delivery date and improve your quality needs to be seriously investigated.
Jig-grinding is nearly always overlooked like a meaningful machine tool for injection mold making. Yet, from my experience, this is a very valuable machine that gets the task done quickly and intensely accurately.
How come the jig-grinder overlooked?
It can be overlooked partly because most toolmakers consider it just as one outdated machine which reaches just best for round holes or time intensive contours that you should done on a CNC milling machine. It's correct, it's not common, it really is primarily utilized for round holes, and yes it does do well at contours just like you will spot inside a gauge for inspection.
For this reason it is just a secret weapon for creating a plastic mold. Because it is so overlooked, so efficient and thus accurate, you need to have a second look only at that tool with the not so distant past. Some shops run their jig grinder all day long, carrying out a variety of tasks.
How can the jig grinder save me money and time?
Some really good instances of time consuming tasks it may flourish:
Blind hole floors. These are always annoying to do; either you mill them extra deep before heat treat and grind to suit, or else you leave stock for post heat treatment machining. In any event, it is just a bother to obtain the depths directly in a simple manner. Using the jig grinder, you exit them shallow before heat treat, and just utilize a CBN wheel to rapidly grind the depth perfectly. This can be much faster and easier than hard milling or guessing in the depths when grinding.
Bosses and other details. Why EDM them when you can do it inside a fraction of that time period?
Adding relief to cores and core pins. You can either work with a Ded-Tru machine, or even a spin fixture with a surface grinder, or hard turn your cores. Or do much of the task on the jig grinder.
Ejector and core pin holes. While almost all knock out holes are WEDMd these days, it is possible to applications in the event it makes sense to jig grind them.
Pockets, whether round, square or rectangular. It is irresistible a jig ground pocket. This is a great application for locators inside the core and cavity blocks. Using this method you are assured of perfect alignment.
