Face milling, especially high volume, with the High-Feed Milling method is perfect for creating a good platform for further machining operations or a final finishing. In most HFM applications, you’ll often get such close tolerances that only final finishing is needed. […]
Today, as more shops are equipped with high-speed CNC machining capability and sophisticated CAM programs, high-feed milling (HFM) is becoming the methodology of choice to remove as much material as possible in the shortest time. Basically, HFM is a roughing method developed for high metal removal rates to increase productivity and save machining time. [...]
HeatBy using trochoidal paths you can minimize heat build-up. Controlling heat is paramount in getting consistent performance from high quality tools in difficult alloys. Heat dramatically reduces tool life and is a major cause of tool failure. […]
The type of fouling (chemical make-up and physical characteristics) or residue the molding process leaves behind on your tooling will help determine your cleaning requirements. Many resins contain stabilizers, […]
Mold cleaning is a process where major maintenance bottlenecks often occur because molds are pulled faster than they can be cleaned and made production-ready. I have visited plants where molds waiting to be cleaned line hallways and toolrooms, taking up valuable bench space. […]
Creating a repair plan for some companies usually means setting a mold on a repair technician’s bench with instructions such as “mold flashing, fix it.” Other companies might have a log or notebook that follows the mold, which the technician must decipher and then decide what to fix. […]
Regardless of mold type, the goal of a maintenance shop always is the same: get a mold production-ready after it has been removed from service. […]
In order to understand the causes and related problems associated with heater failure we should first understand the construction of a heater. […]
Temperature control has a great deal to do with the life of your heater. There are many different types of temperature control on the market today. It will be impossible to cover all of them, so this article will cover the benefits, as they would affect heater life. […]
Heater removal can be very difficult, if the heater has arc welded itself to the inside of the heater hole. You will continue to experience heater failure if the heater is not removed with care. When a heater is removed by drilling with a size-for-size drill, the drill will cause scallops in the heater hole, [...]
