Carbide Coatability: Trade Shows & Events
A clear and intact substrate surface is important to the success of a coating deposited on a carbide insert. This article looks at the surface problems and contamination, introduced by the insert manufacturing process, that the coating company or insert user must correct before the insert is ready to be coated.
Saving Saw Bucks: People & Companies
Advancements in bandsawing are allowing shops to closely control the cost and precision of the operation. This article looks at such innovations as informational computer programs that provide advice on workpiece positioning and machine settings. Improvements in blade design and the applicability of these new blade geometries is also covered.
A Simple Groove: Turning Performance
This article discusses the trend among insert makers to consolidate chipbreaker designs and carbide grades. The result is the three-chipbreaker/three-grade matrix many insert makers have adopted in some form. The evolution of the chip-forming groove is also traced, and an ANSI proposal for a grade identification system is described.
Bushings Get It Straight
Guide bushings are used in difficult holemaking applications to ensure that the drill produces round straight holes. This article discusses the types of bushings commonly used and the materials they are made from. Guidelines for sizing bushings for a given operation are also supplied.
Eye on Ions: Drilling Performance
Ion implantation bombards a tool's surface with accelerated metal ions. According to this article, the process increases tool life and the performance of tool coatings. Two theories explaining why the process works are also discussed.
Switch Drills?: Drilling Performance
For drilling standard holes in metal, there are three primary types of drills: twist, spade and indexable insert. This article discusses the pros and cons of each design and the applications for which each might be appropriate. Factors considered include hole depth, tool cost, drill speed, coolant delivery, tool inventory required, machine tool requirements and expected tool life.
Deep Thoughts: Drilling Performance
When hole depths exceed four times the drill diameter, problems with cooling and chip evacuation can arise. This article discusses these problems and the drill geometries, machining parameters and coolant options that can minimize them. Charts are included giving speeds and feeds for various workpieces and drill diameters.
The Common Code: Turning Performance
In 1995, the Big Three automakers dropped their individual quality programs and requirements for suppliers and adopted a common program based on ISO 9000. This article discusses how the automakers' standard, called QS-9000, was developed and how they plan to implement and enforce it. Some advice for suppliers planning to earn QS-9000 registration is also given.
