  • Speedgrip Chuck Company Design B-39461

    With over 40 years of experience, Quality Tool and Gear in Redford, Michigan has become known as a leader in the Gear Industry. They recently purchased a new Mazak QTU-350 CNC Lathe to turn their small family of input gears. The new machine made them more efficient, however their current method of holding the parts nullified the benefits of the new machine. Fred Pelle, plant manager, contacted John Kaczmarek of Marathon Industrial Sales. John is the representative for Speedgrip Chuck Company for eastern Michigan. John gathered the necessary data for the Speedgrip engineering staff to design a solution. The result was Speedgrip design B-39461. Mounted directly to the machines A2-8” spindle and connected to the drawtube, actuating the assembly was simple and efficient. This special external diaphragm chuck incorporates several interchangeable pin and ring assemblies that are designed to locate on the pitch diameter of each gear. The original chuck was designed to hold five different parts. They have since added three more pin and ring assemblies.    

    Angelo Berlasi, plant manager commented, “The biggest improvement this new chuck produced is the reduction in cycle time and the overall quality of the parts. Because the chuck locates on the pitch diameter of the gear it eliminates the need for the operator to indicate the part. This reduced the run time per part by 30 to 60 seconds or more, based on the operator's ability to indicate. The quality of the part has also improved since the variance in the indicating has been eliminated. The chuck also insures that the spline is within specification, resulting in a more consistent part is provided to the next operation of grinding the gear teeth. Another benefit we have realized is the ability to reduce the amount of stock left for gear grinding during the hobbing operation. This has reduced the gear grinding cycle time, reduces grinding wheel wear, and reduced the frequency of dressing of the grinding wheel.”
