Grinding Wheel Dressers And Precision Surface Grinding

Despite the fact that a great deal of precision surface grinding has been replaced by Wire EDM, there is still a demand for the skillful use of grinding wheel dressers. This is one of those toolmaking skills that requires considerable time and patience to master.

The skill to accurately dress angles and radii on surface grinding wheels is half art and half science, well maybe mostly science. However, it does take considerable experience to become accomplished and accurate.

Grinding Copper Electrodes

By far the majority of copper electrodes are manufactured on CNC machines these days (thankfully!), but the need for grinding copper electrodes still comes up frequently.

The main difficulty with grinding copper electrodes is the loading of the wheel and the burrs thrown up. There are several simple solutions to this problem.

With the proper technique you can even use fine wheels, such as a 120 grit aluminum oxide wheel to grind the copper electrodes. Find out just what the secret is by visiting our website:

Tips For Plastic Injection Mold Making-Good Mold Design

Do not skimp on the design

Some shops do not have an in-house designer and must outsource their design work. This is fine and works quite well- unless the boss decides to save money by cutting costs on the design. This is just asking for trouble.

Even with high-quality mold design, building an injection mould is fraught with potential problems. When the design is faulty or missing details it can eat up the profit margins very quickly. For example a simple feature like radii that interfere in a shut-off area can be very time consuming to troubleshoot and handwork at the end of the job.

The fit of precision holes to their components is another rather common omission in mold designs as well. Often this does not show up until assembly, at which time the mold maker must make new components or modify existing ones.

Another overlooked area is the draft angles of molding surfaces. The mold maker might not question the design when no draft is specified, and as a result, the part will not eject in molding. Draft angles are obviously much easier to the machine before the mold is finished!

Top Tips For Injection Mold Making-Be On The Same Page

Make sure the project manager, mold designer, and mold maker are all on the same page.
It helps immensely to take some time at the outset of a job to have a meeting where the big picture is discussed. It is always much easier to work on the various aspects of the job when you have a clear idea of what is required.
Many hours are wasted when several people figure out the same problem independently. Mistakes can be minimized by going over the procedure together, plus everyone knows who is responsible for what.

Use A 3D Model To Get The Picture

As a mold maker, I’ve never understood why some bosses are so reluctant to allow the mold maker five minutes to familiarize himself with the molded part he is about to build a mold for. This would save a lot of visualizing and guessing. It is always much easier to begin with the end in mind.

This seems so obvious, but it is rare that the moldmaker actually gets to see what it is he is making! It is almost as if somebody thinks it is cheating or something! Why not go ahead and give the poor guy an advantage? It only means higher productivity!

Tips For Plastic Injection Mold Making-Concentrate On Your Best

Every shop has it’s own strengths and weaknesses. Do what you do best and leave the rest is usually good advice. You may really want to learn something like horizontal milling, but does it make sense to sacrifice your limited time and energy?
It is surprising how much time you can waste pursuing pet projects that suck up your time and energy. I know a guy who was bent on having his EDM dept. set up to use pallets. He wasted thousands of dollars and a lot of time until he came to the realization that it is a great idea but just would never work in his case.

Online OSHA Safety Training

With travel costs going through the roof and the economy slumping, our business travel had been reduced to revenue generating or essential travel only. Sometimes the powers that be fail to realize the critical needs of the company.  Especially when requirements such as OSHA Safety Training and hazmat training is needed for over half of our employees. Sending the guys away to get trained was no longer an option so I need to find an alternative.  While searching Google for OSHA certified training companies close to our location I came across a company that offers Online OSHA Safety Training.  I didn’t even realize you could get OSHA 10 hour and OSHA 30 hour training online.  That was exactly what I was looking for.

The process for signing everyone up for class was fast and painless.  I was even able to get a bulk discount because of the number of employees that we needed trained.  One of the guys that took the online safety course mentioned how he really liked the fact that the course was self-paced and that he didn’t have to complete it all at once.  In fact most of the guys took two or three days to complete their courses and had no problems.  Everyone passed which was good news for me.  They were also able to print their certificates right then and there once they passed the training and completedd the online exam.

I would recommend online training to anyone that needs OSHA safety training.  The process is so easy and you don’t have the hassle of travel expenses, car rentals, hotel and airfare and everything else that seems to create problems when someone has to travel.

My experience was superb and I will be signing our Hazmat guys of for the Online Hazmat Training courses as well.  If you are responsible for finding OSHA training for your employees I highly recommend getting them online courses.  Some of the courses we signed up for were only $20. I thought that was an awesome deal. The site that I found most useful was it was pretty easy to find the classes I wanted because they seemed to have a pretty broad selection and the actual sign up took less than 5 minutes.  It was the best site I found of Online Osha Safety Training.  I hope you all have as good of an experience as I did.

Small Business Medical Insurance Options

People that work for small businesses or non-profits are regularly offered various medical insurance choices by the business owner. The insurance covers practically almost everything, from trips to the doctor to prescriptions to emergency room trips, etc.

To assist owners of small business make a decision as to what kind of small business health plan fits best with the company budget and the needs of their employees, the below offers information relating to the various types of plans available.

Indemnity plans – These main health plans generally include a deductible. The insurance company will begin to pay the cost of coverage after the deductible has been met. After the covered expenses go past the amount of the deductible, medical bills are generally paid as a portion of the billed amount, generally around 80%. These plans generally offer the most versatility when it comes to selecting where to go for medical care.

HMO (Health Maintenance Organization plans – These main self employed health insurance plans typically allows the covered person to decide on a PCP (Primary Care Physician) from a directory of network authorized providers. A primary care physician is in charge of handling the health care of the covered person. If the covered person is in need of special care from any out-of-network provider, they need to obtain a referral directly from their primary care physician.

The insured individual needs to receive treatment from a doctor in the network in order to get paid by the HMO.

What is Centerless Grinding

In this article, you will learn exactly what centerless grinding is. Further, you will also learn what parts make up a centerless grinder. You will also learn exactly how these parts do their job in a centerless grinder. In particular, you will learn how these parts work in conjunction to prevent the piece being worked on from moving out of the cutting area on a centerless grinder.

If you do any type of metalworking, chances are you’ve probably heard of a centerless grinder. Conceptually and fundamentally, centerless grinders are probably the most misunderstood topic in metalworking. A centerless grinder does the same sort of material removal that a regular grinder does except for one huge difference, there is no spindle used in the process of centerless grinding. By using a centerless grinder, you can greatly increase your output. Centerless grinding will allow you to manufacture a lot of pieces in a short period of time.

Most people just can’t wrap their head around the concept of centerless grinding. It almost seems impossible for a centerless grinder to work the way that it does. At first blush, it’s completely understandable why centerless grinding is so confusing. One would believe that because there is no spindle holding the piece in place, the piece would just go where it pleases outside of the grinding zone. Despite the lack of a spindle, a centerless grinder will usually not allow the piece to get out of the grinding area. If you’re familiar with grinders, you already know that the material is held in place by a spindle or chucked and rotated against another grinding wheel which is rotating at a higher velocity. The other grinding wheel is usually powered by an external motor which is housed in the grinder’s workhead.

How does the centerless grinder work? The pieces worked on by using a centerless grinder will not require you to have holes in the middle, any type of driver, or a worked fixture. The piece you are working with is stabilized and held by a workblade. The work blades are placed in the middle of two other parts.  The workblade is in the middle of a grinding wheel which turns at an extremely fast rate, and what is usually referred to as a regulating wheel. The regulating wheel turns at a slower rate than the grinding wheel turns at. The regulating wheel also turns within a more confined diameter than the grinding wheel does.

Hopefully, the concept of centerless grinding has been made a little more concrete. Centerless grinding is a very efficient way to get large amounts of pieces done in a short amount of time. If you want to do grinding effectively and efficiently without having to rely on a center spindle, then you should definitely look into a centerless grinder.
