To achieve efficient tool life, proper finish and productivity in high-speed work, tool holders need to be as rigid, compact and short as possible to keep the whole assembly stable. Here's what you need to know when choosing a high-speed tool holder. 

When high accuracy, long tool life or high-speed capabilities are important, collet chucks are often the holder of choice.

Chattering and deflection have always been the bane of machinists’ existence, so much so that the sight of a long and slender tool holder will immediately cause goosebumps. If you understand why a long tool holder behaves the way it does, you’ll know that there are ways to fight back against this bending.

Deep pockets in mold cavities can be difficult to machine. Toolholder length-to-diameter ratios are stretched to the max and cutting forces are high. Without the right toolholder, these conditions create the perfect storm for chatter, poor tool life and failing quality control molds. To avoid such problems, consider a wide range of factors when selecting a long-reach toolholder.

Many shops are unaware that a lot of their spindles are BIG-PLUS, so they don’t realize the capabilities they possess.

Constantly optimizing processes and equipment to achieve an advantage over other race teams, Team Penske adopted tooling improvements based on its decision to expand usage of the BIG-Plus spindle interface and tool holders.

Tapping is an efficient way to create threads in a drilled hole and it makes the overall machining process easier. Burley goes on to discuss this in further detail by emphasizing how tapping has changed within the industry over the years.

In a recently published article in Manufacturing Engineering, BIG KAISER contributes to the conversations of the evolution of five-axis machines.

Valuable information on a new standard for balancing tools and tool systems that apply to today’s relevant variables for safe and productive machining.

This topic is important as toolholders provide the critical connection between a machine spindle and the cutting tool.
