Aqueous Cleaning Optimization

Effective parts cleaning is achievable with the proper chemistry and mechanics. Proper equipment design, coupled with appropriate product selection and process control, assures sustainable and cost-effective performance. And a preventive maintenance program makes the performance consistent over time.

In the article “Optimizing Aqueous Cleaning Requires Proper Design and Maintenance,” David Gotoff, product manager at Chemetall, explains how each area of an aqueous process must be optimized, including system design and mechanical action, chemistry selection, key performance indicators, soil management, maintenance, rust protection, rust preventive selection, water chemistry, and drying.

Quick-Change Starts with the Lock Nut

Changing tools in the close quarters of a Swiss machine tool can be a painful exercise as hands tend to brush up against tool tips that are sharp and close to the tool that the operator is trying to change out. Packed with 15 to 20 cutting tools, the space between each toolholder, especially in gang-type setups, can be as small as 2 inches. Not much room for a hand.

REGO-FIX Tool Corp. has created a simple tool to help shops alleviate the cuts and abrasions that so often come from tool changing on a Swiss machine. We published an article that discusses the advantages of this new lock nut wrench that enables the operator to access the lock nuts on collets without contacting adjacent cutters.

Manufacturer Finds Solutions to Common Shop Issues

Manufacturer Finds Solutions to Common Shop Issues

MicroSwiss Inc. out of Naples, Florida, is always looking for clever solutions to common shop issues. One such product development has helped Shop Owner Jeff Bonner doubled part production with a superior surface finish compared with previous processes. The medical device manufacturer runs one Citizen A20 and three L20 CNC Swiss lathes and lives and dies by its ability to provide more parts with better quality and efficiency.

After machining a part for a customer in-house, the company discovered they needed a more efficient solution. Although a grinding wheel was considered at first, screw machines are not designed to handle grinding operations. So Mr. Bonner designed a grinding wheel with a 10-mm shank and a 30-mm head diameter to provide the maximum possible cutter speed. Further modifications were made, and with these changes a single grinding wheel could now produce 30,000 parts.

Multitasking Takes a Turn

Turn-mill machines are capable of both rotating-workpiece operations (turning) and rotating-tool operations such as milling and cross-drilling. Typically, the machine is recognizable as a horizontal or vertical lathe, with spindles for milling and drilling available at some or all of the tool positions.

Willemin-Macodel, Inc. offers a line of multitasking machines designed as five-axis bar-fed milling machines, but they include 6,000-rpm turning capabilities on the A axis and tool magazines ranging in capacity from 24 to 72 to accommodate both milling spindles and turning toolholders (a certain number of which can lock the tool, oriented at a specific angle to cut as the spindle turns like a lathe).
