Tooling & Workholding
Search and find specs for these machines.
A rigid machine and hard cutting edge are the beginning. Other considerations relate to system rigidity and keeping the cutting force steady.
Form tools are traditionally associated with non-CNC machines, but in certain applications they make sense on modern machines as well.
This company is embracing high-performance tooling on its turning centers. The "sticker shock" is no reason not to do this. In one case, though, the shop found a way to limit the cost of the tool and increase productivity at the same time.

Horn has added a type-842 cartridge system featuring smaller dimensions for machining smaller workpieces to its 940 modular grooving system comprising a basic holder, a grooving toolholder and a cartridge.
Chip control is the bane of every shop’s existence and knowing how to consistently break chips and control burrs in ductile steels like SAE 1018, 1020, and 8620 is the holy grail of the tooling industry. When a shop experiences chip control issues, it affects their bottom line either through machine downtime, scrapped or reworked components, lost inventory due to broken tools or even employee injury.
Components for automotive transmissions are typically made of ductile steels such as SAE 1018, 1020 and 8620. Turning these parts is often plagued by problems with long, stringy chips. This article from Sandvik Coromant addresses the complex variables and strategic trade-offs that must be considered in designing the most effective insert for this application. The insights into the problem and its solution will help anyone think more clearly about vexing chip control issues.
The developers are calling it the world’s largest anti-vibration boring bar—one that is capable of machining a bore 12 inches in diameter and as long as 165 inches. Sandvik Coromant designed and manufactured this boring bar in cooperation with lathe builder Gurutzpe Turning Solutions.
The hardness and toughness of a tool are generally counteractive forces, and finding the right mix can be a challenge. Wouldn’t it be nice to have both?
