The is no general rule to cutting tool shank insertion as a multiplier for shank diameter. All tool holder types have different requirements.

Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.

Deep hole boring comes with challenges created by the inevitable deflection that occurs when trying to finish a hole of a substantial depth. Various factors determine the best approach to solving the issue, and it’s important to consider all factors before choosing a solution for your boring needs.

Even among experienced machinists, choosing the right insert for boring a hole remains a difficult process that is fraught with myth and misconception. However, it is no myth that insert selection can completely save or kill performance on an application.

What to check when boring performance goes bad.

The importance of meticulously prepping, starting, and finishing holes can’t be emphasized enough.

BIG DAISHOWA has introduced a new, high-precision hydraulic chuck for clamping straight shank tools with diameters ¼" to 1¼" and 6mm to 32mm.

The limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. Enter the relatively simple and affordable twin cutter, which can solve this and virtually any other holemaking problem.

Gearench produces more than 40 different product lines for the oil industry and selected the Speroni MAGIS 400 tool presetter for its precision.

With a little knowhow and the right tools, see how you can significantly reduce cycle time by rough boring instead of performing a helical interpolation with a mill.

Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.

Lead angles close to 90° more effectively combat potentially damaging chatter and vibration because they apply the least amount of radial pressure.

BIG DAISHOWA has launched the HMCJ, a super-slim milling chuck with peripheral coolant supply, designed to support heavy-duty and finish end milling tasks with power and precision using Ø1/2” or Ø12mm cutters.

BIG DAISHOWA has expanded its lineup of Fullcut Mill FCM tools to include larger diameters and additional lengths.

Runout can be fickle, but finding a solution for it can pay significant dividends. How a little wobble can really increase your costs.
