What is indution hardening and what is Induction Heating?
Induction Hardening: Induction hardening is a method of steel surface heat treatment. In order to be able to induction heat treat (harden) the surface of a steel, […]
What is Hardenability?
Hardenability is the ability of the steel to produce the appropriate hardness in relation to the amount of martensite when quenched for its austenitizing temperature into the appropriate quench medium. The resulting hardness will be according to its cross-sectional area and chemistry (composition). […]
Introduction to Characteristics of Tool Steels
Water Hardening Tool Steels: Low hardenability, water quench necessary to form martensite.Oil Hardening Tool Steels: High wear resistant steels. […]
How to identify tool steels
In order for tool steels to be identified by a toolmaker, it is necessary for the toolmaker to understand the method of identification and classification of tool steels. The purpose of gaining this understanding is that there are so many different tool steel manufacturing companies that will produce a very high grade of tool steel [...]
Introduction to History and Applications of aluminum tool
Using aluminum tooling for injection molding is not an entirely new concept. Initially, prototype molds were most commonly made out of aluminum, although the automotive industry has used it for years and it has slowly been gaining popularity with companies outside the automotive realm. […]
Feature Considerations in graphite electrode milling
Dust ProtectionSince graphite is such an abrasive material, protection of the CNC’s working parts from graphite dust is extremely important. Some machine tool manufacturers have developed turnkey solutions1 that address these application-specific needs. […]

How to Choose the Correct Grade of graphite
Now that we know generally how graphite is made, how do we choose the correct grade? In order to maintain cost effectiveness, an EDM shop needs to choose EDM graphite that provides dependable quality at a good price. […]
achieve top accuracy in electrode manufacturing
More accurate electrodes will reduce leadtimes by eliminating the need for secondary processes such as polishing. Shorter leadtimes allow moldmakers to turn jobs over more quickly, driving higher volumes and better profits. […]
Graphite and EDM Performance
EDMing thin ribs is a difficult application. High-speed machining of the elec-trodes has made it possible to fabricate these electrodes from grades that are not capable of maintaining the detail in the cavity. The ideal graphite grade for thin ribs should have a flexural strength above 10,000 psi. […]
