 Since 1957, General Die Casters has worked closely with their customers, to design, manufacture, and deliver the custom die castings they demand. In March 2010 they opened their new 90,000 square foot expansion casting foundry in Twinsburg, OH. service the Appliance, Automotive, Commercial, Computers & Peripherals, Electrical, Industrial, Lawn & Garden, Recreational and Transportation Industries.
Advanced Chemical Solutions was invited to discuss coolants that would not only perform well but also not have an odor, foam or cause dermatitis. Mark Pierson from ACS with closely with Keith Kish, the Director of Manufacturing Engineering at General Die Casters. According to Keith, "I was looking for an economical coolant that would not stink, foam or have skin issues for our employees. Advanced Chemical Solutions evaluated our facility and provided Nano Tech 6800 for testing." General Die Casters has a good number of CNC machines from Brother, Mori Seiki, Chiron, Takisowa, DMC, Kitako, and a good number Haas machines. Taking good care of their employees is important to the the company. Recently, several employees celebrated 20 years of service at the company. One of them was Anderson Grant, the first shift operator “In most companies, it’s very rare to see employees who reach 20 years of employment. At General Die Casters, it is common to see people reach 35 years at the company. We have a work culture where there is mutual respect and support of one another. When one of us succeeds, we all succeed”, says Anderson. Having odor free coolant that didn't cause dermatitis is part of keeping employee morale high. According to Keith, "Nano Tech 6800 is absolutely the best coolant we have ever used in our machines. No Monday morning odor, coolant stays fresh and clean." But what about tool life? Keith tells us "This coolant has dramatically improved our work environment helping to keep our machines cleaner and improving our tool life." compiled & edited by Bernard Martin  As more and more of our customers are using Martindale Gaylee Circular saws we put together this guide to the commonly asked questions such as "Is there a rule-of-thumb for the number of teeth?" or "How much side clearance should I have?" Here we cover a lot of the fundamentals of selecting the right circular saw blade configuration, some tips, tricks, and troubleshooting for when things go wrong. Circular Saw Feed Rates These are general cutting speed recommendations for circular saws used in metalcutting from Martindale/Gaylee. The may vary from application to application but are basically some general suggestions starting parameters when using high speed or carbide saws.
Selecting the Proper Number of Teeth in Your Metalcutting Saw Generally speaking, deep cuts and soft material require fewer teeth for chip clearance and stronger teeth (landed) Thin material requires more teeth, but keep-in-mind that at least 2 teeth on the blade need to be engaged in cut.
Rake Angles and Side Clearance AnglesSIDE CLEARANCE (Tangential Clearance Angle) This is also known as dish or hollow grind. You measure down the side of the tip and the difference it is the difference between front and back. As you cut, material it gets compressed and springs back after the cutting edge passes. A steep side clearance angle gives plenty of room for the material to expand and prevents thermal expansion of the base material. Keep in mint that a very flat side clearance angle can provide a smoother cut in some materials. For stainless steel and tenacious metals such as copper, zinc, tin or lead an increase in the side clearance is desirable as these materials tend to "spring back" (thermal expansion) on the blade. RAKE ANGLES Rake angle is the term used to describe the direction of the blade’s teeth, as referenced from the rotation and central axis of a saw blade. If you imagine a line going from the exact center of the blade to each tooth, having the front of the tooth directly on that line would be a zero degree rake angle. The rake angle of the blade is described in comparison to that imaginary line. A positive rake angle meana that the teeth are angled more towards the angle of rotation, while a negative rake angle would mean that they are angled backwards, away from the direction of rotation. Generally speaking, the preferred rake angle is:
 Why do Circular Saw Blades Break? It's commonly known that when saw thickness is less than 0.125″, keyways can cause stress risers and cracks. That is why washers are often used. However, Breakage, Wobble and Rubbing problems are often caused by how the washers are mounted on either side of saw.
Remember, washers drive the saw in the absence of a drive key. They must always be clean, flat and bur-free. A speck of dirt will let saws wobble and cut oversize. If a saw breaks, it may score the washers. Always check for scoring marks around saw hole for dirt, chips or grit. Shiny spots, as small as a pinpoint, indicate that chips where imbedded under washers. Circular skid marks indicate the nut was not tight. Generally speaking:
Saw Blade Teeth most often break as a result of:
NOTE: HSS saws will turn colors as they heat during cutting. A straw color is the limit. The saw will lose its temper when it starts turning blue. In January of this year we welcomed a new member to our Browne & Co. sales team and with manufacturing companies opening up again, it's about time we introduce you to Jeff Terrace!
Just before joining Browne & Co in January 2019, Jeff worked at Hoffmann Group, a German cutting tool, hand tool, workstation and storage solutions manufacturer. Jeff has been working as an InovaTool representative since February of 2019 and recently joined Browne & Company at the beginning of 2020 as our Cutting Tool Specialist. Please send Jeff and email or give him a call to introduce yourself or pick his brain about an application question.  As companies begin to implement policies to protect from any outside physical interaction in their facilities due to the coronovirus, our entire team as Browne & Company is still available to to meet with you via voice or video call (Face Time) to provide technical support.
