What is the advantage in 2-D and 3-D?
3-D design differs from 2-D design in a pivotal way: in 2-D, drawings are the master documents that define how each part in a tool assembly should be made and illustrate how the product comes together. […]
Feedrate Optimization is very important in CNC machines
What if you could run almost all of your CNC machines, not just your high-speed equipment, 10, 20, even 30 percent or more without tool life or equipment longevity decreasing, and improve the surface finish of your molds. […]
Introduction to Machine Simulation in CAM system
Because of the additional complexity of multi-task programs with their multiple tools cutting at the same time, multiple spindles, and parts being exchanged between multiple spindles, the need to accurately simulate and validate the programs before executing them on the machine tool becomes very important. Within machine simulation, there are a number of distinct phases: [...]
Introduction to Heat Shrinking Technology
toolholding system to note is heat shrinking technology. This technology is based on heating up and cooling down a toolholder through induction technology. […]
Introduction to Universal Toolholders
toolholding system to be discussed are universal toolholders. With two choices available—one for light-duty applications and one for medium- to heavy-duty applications—users have the possibility to gain the very important advantage of vibration damping for improved tool life and workpiece surface finish at a price point competitive with most high-end colleted toolholder systems. [...]
Introduction to toolholders for Polygonal Clamping
The polygonal clamping system is one of those highly engineered devices that is surprisingly simple: a ground polygon-shaped bore rigidly clamps a cutting tool in three places.For high-speed applications, polygonal clamping is a great solution since the clamping of the tool shank is done by the elastic deformation of the holder. The main advantage of [...]
Introduction to Hydraulic Toolholders
Special toolholding solutions are applied for particular customer solutions. There is one toolholder that can be applied for most of the applications—a hydraulic toolholder. A hydraulic toolholder uses a different way of clamping the cutting tool compared to systems of conventional toolholders. Introduction of force is done via a screw (with a screw, a piston [...]
We should consider Balance in high-speed machine
With machine tool capability a given, and the proper choice of cutting tool and toolholder being made, HSM is a snap, right? Not exactly. Particular focus must be given to the assembly of tool and holder. […]
Toolholding is very important in High-speed machine
Cutting tool challenges such as the ability to avoid chatter, deflection and minimize runout are equally determined by the rigidity, concentricity and balance of the toolholder. There are numerous choices for toolholding, and no one set answer for all applications. Among these are collet style, those that use a (arbor) set-screw, hydraulic holders and of [...]
What are Cutting Tool Requirements in high-speed machine?
To permit for these maximum rpm applications, cutting tools have to be precise and long lasting, or more accurately, predictable, especially in unmanned operations. They also have to be capable of holding tolerance at these high speeds, and resist deflection and vibration especially in applications with longer overhangs. Balance, edge preparation, geometry and cutting tool [...]
