Thread Grinding with ‘A’ Axis

With several factors propelling a surge in demand for parts with technically complex external and internal threads with large pitches, the need for better accuracy and efficiency has created challenges.


Finding Significant Increases in Honing Accuracy

Single Stroke Honing is a single-pass process that sizes and finishes a bore with a series of progressively larger superabrasive tools adjusted to a preset diameter.


Compact Cylindrical Grinding Machine for High Production

United Grinding recently introduced its Studer S11 small-parts production grinding machine to the North American market. An online video demonstrates an interesting cam-actuated loading system that’s available with the machine.


Faster Setup for Centerless Grinders

The new series of Jupiter centerless cylindrical grinding machines from Erwin Junker Machinery (Elgin, Illinois) addresses the limitations to applying this process to small- to medium-sized batches.


The Benefits of Vertical Thread Grinding

Holding a workpiece in an upright position improves numerous aspects of thread grinding. From top to bottom, this approach represents a major change in the way precision leadscrew-type parts are produced, as embodied on Mitsui Seiki VGE60A.


Anatomy of a New Bond Technology

A new vitrified bond technology features proprietary chemistry to achieve higher performance as well as extended wheel life for today’s advanced grinding machines.


Labor Savings in Grinding

Representatives of a grinding equipment supplier comment on how this critical process can be made more efficient.


In-House Tool Grinding: the “Indirect” Machine Tool Investment

Though CNC tool grinders are used primarily by cutting tool manufacturers and regrinding services, several factors have made these machines increasingly attractive for in-house tool grinding by production facilities.


Tool Grind Workholding System Limits Runout

Precision manufacturing requires minimal tool runout, but the amount of runout that is acceptable can be dependent on part tolerances and is often related to the size of the tool.


Small Grinding Center Offers Big Productivity Boost

This vertical grinding center for small chucked components with a maximum diameter of 100 mm was developed specifically to meet increasingly higher output levels and shorter cycle times.
