Why You Should Take Another Look at Shrink-Fit Tooling

Shrink fitting uses heat to clamp the cutting tool into the toolholder. A machine using an induction heating device or hot air heats the outside diameter of a toolholder, expanding the inside bore, which starts slightly smaller than the cutting tool shank's outer diameter. An adjustable stop disc ensures the toolholder isn't overheated.

A Pitch for Thread Grinding | Cutting Tool Engineering

To reach the bottom of a 200-tpi thread form, the tip radius of the grinding wheel must be 20µm to 25µm (0.0008 " to 0.001 ") wide. "In the past, people would always ask us to help them grind threads under a 0.005 " tip radius, and we'd all duck and hide," Hitchiner said. "There just wasn't a good answer.

1/2″ (12.5 mm) or less in diameter, a straight shank drill is placed in a Jacobs chuck. The Jacobs chuck is then fitted into the tailstock spindle. Holes larger than 1/2″ (12.5 mm) in diameter are made with taper shank drills, Figure 15‑7. Drills that have taper shanks too large to be fitted in the

Getting reaming right | Cutting Tool Engineering

The surface finish obtainable when reaming generally depends on the workpiece material. The range for cast iron is 50 to 80 rms and 30 to 60 rms for steels, and a PCD reamer can impart a finish as fine as 8 rms in aluminum, according to Bysterbusch. Sometimes a hole is bored prior to reaming, but that's not mandatory.

One hundred and fifty years of history of the Morse taper: …

A Morse taper is defined by the angle that the taper surfaces make relative to the longitudinal axis of the component and by the mismatch angle between the male and part. The original Morse taper angle defined by Stephen Morse for tools was a relatively small angle of 2° 50′, with the mathematical relation that tang 2° 50 = 5 %.
