PCD Router Bits for Abrasive Composite Materials

Machining composite materials often represents a challenge with standard tooling.  Special cutting geometries are required to perfect the finish on very abrasive, hard to machine materials such as HDF, fire-rated MDF,  Thermoplastics, Phenolics,  fiberglass-reinforced plastic composites, cement fiber panels and other similar composite panels.   GDP | GUHDO has introduced some standard PCD tipped tooling  to machine such challenging materials, available from stock.  These router bits feature solid carbide bodies and 2 continuous PCD tipped flutes that are positioned on opposing axial shear with PCD bottom cutting to provide cleanest finish.   Very suitable for nesting applications.  Typical machining parameters for Thermoplastics are 15,000-18,000 rpm and a feed rate range between 1 – 5 meters / minute.  For other composite panels 18,000-24,000 and  6-9 meters / minute.  If too much heat is generated while cutting plastics, the rpm should be reduced to maximize tool life and performance.

Protect your spindle when not in use!

Our HSK63-F spindle filling piece serves as a protection plug to prevent dust from entering into the router motor while the CNC is either being moved, or is performing a saw/grooving or horizontal drilling application. Item# 6375.100.00. A great way to insure against more costly spindle repairs that are avoidable. #HSK63Fdsc_0393

Are PCD Blades Right for Your Shop?

Regardless of whether you’re a small to medium sized cabinet shop or a large production facility, if you haven’t considered PCD (polycrystalline diamond) saw blades perhaps now is the time!  Materials such as particle board, MDF, laminates and solid surface are all excellent candidates for diamond saw blades. When comparing Diamond v. Carbide, depending on the machine and the material application, diamond saw blades can outperform carbide by a ratio of 30-50 times!  

PCD Main Blade

PCD Main Blade

Over the years, diamond saw blade production has improved tremendously and as an industry, we’ve seen steady prices reductions.  With the multitude of suppliers now offering PCD tooling it’s important for you, the buyer, to do the proper vetting of the individual supplier.  There are many factors to consider when looking at the price of a diamond blade, including the plate and diamond quality, the amount of diamond used, and the cost to service the tool.

Here is an example use case from one of our customers:

A cabinet manufacturer located in Florida and utilizing a Holzma Model 430 beam saw found they were changing their carbide main and scoring blades on a daily basis! At the beginning of 2016, they invested in a 450 mm PCD main and 180 mm PCD scoring saw. The diamond saw blades were put into production on January 4th and were removed from production for sharpening on April 7th, 69 production days! Needless to say, a second diamond set was ordered.

From replacing carbide saw blades on a daily basis to running 69 production days on one diamond set! Considering the cost of a diamond set can be 10 – 12 times the price of a carbide set it leaves little doubt that in this case, the initial cost factor is far outweighed by the extended tool life most certainly justifying the investment. In addition, this doesn’t take into consideration the cost of having to maintain the huge number of carbide sets needed for rotation purposes or the machine downtime savings created. When deciding whether to switch, be conservative in your cost analysis and base your justification on the diamond tool lasting 25x longer than carbide.  You won’t be disappointed!
