Technology sheet: Turning Spinning Tool technology

History

The first spinning-tool technology was developed jointly by Mori Seiki and Kennametal around 2008.
Designed to distribute heat and wear more effectively than a single-point lathe tool, the new turning spinning-tool technology can increase productivity by up to 500% and tool life by up to 2,000%. This cutting technology employs a specialized insert similar in design to a round, or full-radius insert mounted at the bottom of a cylindrical tool shank held in a rotary spindle.

Technology sheet: Machining CFRP/GFRP Composite material.

Introduction.

*CFRP stands for Carbon Fiber Reinforced Plastic.

Technology sheet: Why we can machine graphite with Diamond tools.

Definition

Graphite has specific properties that make machining a challenge. It’s strong, but also brittle, and is susceptible to chipping if not handled properly. Cutting Graphite (or carbon) is different from cutting Metals. Metal exerts plastic deformation when a tool edge cuts it producing a curl or chips. When graphite is machined small powder-like particles separate from the work piece as a result of brittle fracture caused by the stress produced by the cutting tool edge.

Technology sheet: Carbide inserts Wear Failure modes.

Definition

Tool wear describes the gradual failure of cutting tools due to regular operation. It is a term often associated with tools used for example on turning, milling, drilling and other types of machining operations where chips are made. We could also say “We started with a new cutting edge and at the beginning of the operation everything was working well. After a certain amount of time things started to change.

Technology Sheet: POLCA

Definition:

POLCA stands for Paired-cell Overlap Loops of Cards with Authorization. POLCA is a production steering and control system for high mix/low volume and custom made products environments aimed at keeping the lead time at the shop floor short.
