In the automotive industry, it’s all about high volume and automation in a demanding production environment. But there are other challenges, too, such as switching to aluminum or composites to lighten the load. Our tools solve many of these problems. Consistent tool geometry and quality allows repeatable results. We help automakers save money not by offering the cheapest tool but by offering a premium tool that produces the lowest cost per part.
RobbJack’s Advanced Applications Testing Facility is available to help solve your automotive applications. Send us your material and we will develop a solution.
When one automotive manufacturer switched to aluminum, over 20 toolmakers tried to cut the part at 80 inches per minute—and failed—on multiple counts. However, RobbJack’s A1-303 ran at maximum RPM and cut 400 inches per minute with zero chatter—a 500% advantage. Plus, the tool lasted 10x longer than the nearest competitor. The RobbJack A1-303 was the only tool series that could meet the design and performance benchmarks required.
Composite materials are prized for their durability, weight-to-strength ratio and corrosion resistance, but often challenge automotive machinists with tool wear, delamination, uncut fibers, fiber pullout and scrapped parts.
The innovative W-point geometry on RobbJack’s Solid PCD-tipped W-point drill supports the material as it pierces through and its sharp outer edge shears the material without delamination, uncut fibers or fiber pullout. One manufacturer was using competing tools to drill holes in ¼” thick carbon fiber epoxy, and only got 180 holes drilled. When they switched to RobbJack’s Solid PCD-tipped W-point, they got 4,500 holes drilled with just one bit—a whopping 2500% difference.
Hardened Tool Steels, Stainless Steel and Powdered Metals
Hard milling applications are becoming more complex with tighter tolerances. To complicate the matter, poor tool life requires tool changes in the middle of a job that often result in costly scrapped automotive parts.
The RobbJack DM/MDM Die/Mold Carbide end mill offers tighter tolerances, lasts longer in difficult areas like parting lines, and produces better finishes that reduce or eliminate the need for polishing. It performs well on materials up to 70 HRc and can handle dry cutting and high temperatures. The RobbJack DM/MDM Die/Mold is made of a new carbide material and a new coating combination that lasts 450% longer than comparable carbides and coatings designed for hard metal applications—and reduces wear by 909%.
