I.D. Grinding Quills
Inner Diameter (I. D.) grinding quills are used by manufacturers and users of CNC grinding machines. Years ago, a grinding quill was just another steel tool, and precision was limited by the skill of the man who guided the tool. Even today a trained professional can achieve impressive results with primitive implements, but it is a time-consuming task.
High Quality, Fast Throughput
The market wants quality, and wants it fast. Manufacturers depend on machines for craftsmanship, and high quality depends on superior tools. A new type of craftsmanship is involved in the making of tools. Grinding wheels of new abrasive materials and bondings have improved mechanical properties. But they do tougher work than earlier tool generations. So while cubic boron nitride (CBN) grinds more effectively than silicon carbide does, it also requires a higher grinding pressure.
As new manufacturing processes evolve, grinding quills become increasingly critical for high precision operations. They must satisfy unconditional criteria:
- Rigidity to withstand high pressure
- Lightweight to counteract critical eigenfrequencies
- Perfect rotation to achieve speeds up to 20,000 rpm
The "Hole" is the Sum of its Parts
All machining processes depend on smooth interaction within the system. The grinding quill, the collet, the wheel clamp, and the CNC machine itself must merge to a perfect entity to ensure a perfect result. A quill rotation of 2 to 3 microns can achieve a finish smoothness of 6 to 8 microns. Today, a quill is a vital component in the grinding process. By choosing the optimal grade of tungsten carbide, the quill's properties can be tailored to meet each specific task. A fine bore for running the coolant through the interior of the quill is a sought-after innovation.
Only the Best
Today's market demands place heavy responsibility on the quill fabricator. There must be machining resources for processing in a variety of metals while adhering to minimum tolerances. There must be know-how concerning tungsten carbide grades. There must be quality control resources to enable precision checking of each individual quill. A grinding quill is part of a customized solution, unique for each customer. A quill must meet the requirements of grinding wheel manufacturers as well as OEM machines for numeric control.
For all customer demands and for all makes of machine, you need a tool fabricator you can rely on. By means of flexible manufacturing services, top-class quills are assured to meet all specifications, allowing you to keep your own commercial promises further down the line: grinding with the highest attainable precision and efficiency.
