Machining

Jones and Shipman introduces their new Suprema 1000M cylindrical grinding machine with productivity enhancements not found in their current 1000mm machine.

Emuge Corp. announced the introduction of an extensive, expanded thread milling program for oil and gas manufacturing applications, including a new line of solid carbide thread mills and insert thread milling systems.

For the 44th episode of the Grinding Doc Video Series, a shop recently asked Dr. Jeffrey Badger, Cutting Tool Engineering magazine's Ask the Grinding Doc columnist, to settle an argument about the best way to run the dresser when rotary plunge diamond dressing aluminum-oxide wheels.

Since the May issue, I have been writing about our combustion shop's migration from batch processing to single-piece flow, or machining one part at a time. Single-piece flow eliminates work in process. This is desirable because WIP hides part defects and increases lead times and inventory levels.

Continuing the theme of the previous three columns, here are additional tips for enhancing the operation of a CNC milling machine from Shop Operations columnist Tom Lipton.

Boost productivity when machining hubs and other parts. Replace an outdated vertical machining center with a new one.

Reduce energy costs as part of a sustainability program. Replace a waterjet cutting machine with a fiber optic laser cutting machine.

Eliminate part deviations when performing lights-out machining. CAM software with the properly adjusted post-processor for automatically measuring parts on a machine tool.

Representing your company through community involvement accomplishes two goals. Hopefully, you're doing something positive and, in return, raising the reputation of you and your company. You may also gain access to another network of valuable contacts and potential leads.

Spindle bearings support the spindle in the housing and transmit cutting forces to the machine structure. The bearings are intended to hold the spindle accurately in position.

In parting, or cut-off, operations, the objective is to efficiently and securely separate one part of the workpiece from the other. To achieve this, a straight cut is made to a depth that equals the radius of a bar, or workpiece.

Retrofitting old machine tools with new CNCs can make more sense than buying new -- particularly for larger machines.
