Machining

In a typical machine-tool-axis positioning system, the workpiece is mounted on a table that slides along flat, straight guide ways. The table may be supported on the guide ways by rolling elements or by a thin film of oil or grease. A screw controls the table position along the guide way. The rotation of the screw in the nonrotating nut that is fixed to the table drives the table left or right. The rotation of the motor translates into linear table position through the pitch of the screw.

A shop I once worked at had a beautiful cast iron welding table. It was 5' wide × 12' long and had started life as a surface plate for assembling diesel engines. The owner bought it at auction for $100. With a screen in the middle, two guys could work on it at once.

Efficiently machine stainless steel parts without breaking endmills. 6-flute, solid-carbide endmills.

The cutting zone in a machine tool is dangerous. Hot chips and large quantities of coolant are often safety threats, but a tool rotating at a high speed is an even greater one.

Efficient removal of heat from the tool/workpiece interface is the main route to high-productivity machining. Several conventional methods are available to accomplish that -- dry machining, minimum-quantity lubrication, flood coolant and high-pressure coolant -- but cryogenic machining can be added to the list.

A technique I call roll grinding is used to finish corners to match bend radii. Long weld seams that need to be rounded can be handled using a rolling technique with the disc grinder. It takes a little practice, but once you've mastered it, the results look just like a formed corner.

Increase threading productivity while reducing scrap. High-performance, through-coolant thread formers.

Streamline the digital parts library used to produce workholders. Strategic parts management software.

Do you process existing jobs the same way every time? If not, you may be throwing money away every time those jobs are run by having to reinvent the process over and over. If a few weeks or months go by in between runs of the same part, you may forget some nuance, whether it's a specific cutter, a dedicated fixture or a unique method for locating the part.

Capacitance sensors are noncontact sensors used in machine tools to measure the distance between a noncontact probe and a target sensor. Because the probe does not physically touch the target, capacitance sensors are beneficial in instances where the target surface is moving, such as a rotating spindle, or delicate, such as a silicon wafer.
