Octagonal Inserts for Semi-Finishing and Finishing
New octagonal inserts offer eight cutting edges for more economical facing, shouldering, slotting, recessing and chamfering applications. […]
Square, Multi-Purpose Helical Inserts for 90′ Shouldering
The most recent and growing family of inserts are square, helical shapes for improved economy and performance. These new square insert geometries combine the helical cutting edge on all four edges with an additional wiper on one of the extremities to perform for 90′ sidewall milling operations. […]
The Basic Insert Geometries for Milling
For multifunction operations in machining small slots and shapes, various companies offer a single endmill body on which various interchangeable heads can be mounted. The versatility of the system allows shoulder milling, slot milling, small surface face milling, profiling, drilling, chamfering and ramp down operations. […]
Introduction to Basic Types of Tool Concepts
For the machining of dies and molds, a very wide selection of cutting tools is necessary. As an example of a complicated shape requiring a large variety of cutting tools, you might observe the lower part of a mounted mold for injection molding of an electronics panel part,The mold requires facing of large and small [...]
Three Scenarios affect cutting tool cost
To adequately analyze the situation, three scenarios were considered as they applied to the machining community: (1) a decrease in cutting tool cost, (2) an increase in cutting tool life and (3) an increase in cutting tool cost coupled with the resulting increase in productivity. In the first situation, a 30 percent discount was taken [...]
How to Achieve Effective Data Exchange
Although these nine issues may be addressed individually, looking at all of them together is often more effective. Many companies are turning to a centralized and automated data exchange center (DEX Center), which address physical translation, security, system requirements, transmission and data management issues to establishing effective data integration. […]
How to exchange Data in high quality
This is the first – and often the only – area considered by most companies. Current CAD capabilities provide robust data exchange, including standards-based methodologies such as IGES (Initial Graphics Exchange Specification) and STEP (Standard for the Exchange of Product Model Data), as well as direct translators. […]
Introduction to External Heating (Coil Heater)
Coil heaters have been introduced to the hot runner system – greatly increasing the cycle speed and the quality of the product produced. Due to an even heat around the nozzle body, the material is not subject to excessive temperature changes, […]
Introduction to Nozzle Heaters
The torpedo system is one of the first hot runner heated nozzles introduced to the moldmaking industry. The concept is simple – a cartridge heater is inserted into a gun-drilled hole running through the center of several flow channels. […]
Introduction to Tubular Heating Elements
Tubular heating elements are inserted into a milled slot into the manifold. This allows for a more accurate location of heat at the areas that require the most (i.e., nozzle exits). […]
