RETROFIT BRINGS MASSIVE FLOOR-TYPE MILL UP TO MODERN STANDARDS
Mine of Information: An old Gray horizontal boring mill used in the mining industry was electrically upgraded with CNC technology from NUM Corporation by automation systems integrator MasterControls to achieve higher precision, compatibility with RS274 G-code programming, probing functionality, and an industrial PC front-end with unlimited program storage and networking . . . all for a fraction of the cost of a new machine.
PROPER CARE AND MAINTENANCE
Even though a machine tool spindle is a high-precision machine component, more often than not it is handled carelessly, forced to perform well beyond design limitations, or otherwise abused to the breaking point. Ed Zitney of SKF Machine Tool Services shows how proper care and maintenance can make all the difference in both its operation and longevity in service.
ALL PURPOSE INDUSTRIAL VACUUM DOES IT ALL
The compressed-air 110 gal Reversible Drum Vac™ from EXAIR Corporation handles coolant, hydraulic oils, spills, sludge, tramp oil and waste water. Coolant sumps are easily refilled, floor spills vacuumed, or contaminated liquids transferred to filtration tanks in minutes.
THE FOUR MOST FREQUENTLY ASKED QUESTIONS ABOUT SPINDLE REPAIR
In the decision-making process on how best to return a failed spindle into service, Ed Zitney of SKF Services answers four frequently asked questions that are applicable to any operation considering spindle remanufacture.
STICK SLIP! OR, WHAT MAKES SLIDEWAYS AND VIOLINS DIFFERENT?
Minimizing friction is the prime target for many lubricant applications. But this primer from Mobil Industrial Lubricants explains why that is simply not good enough in machine tool slideways, and how smooth and precise slideway operation require special attention to the friction properties of the lubricant.
“DROP-IN” REPLACEMENT ACTUATOR IMPROVES COOLANT HEAD POSITIONING ACCURACY IN GEAR GRINDING
A powerful and compact RSM rod-style screw actuator from Tolomatic is modified to more accurately position a heavy coolant head and improve productivity on a Phoenix II 275G gear grinding machine from Gleason.
SECOND GENERATION: ADAPTATION AND REINVENTION
Winner Take All: Imagine encountering a sluggish economy, technological change, industrial shifts and changes in consumer preferences, all at the same time. To compete within all of these challenges, Emerson Bearing restructured, increased the size of their warehouse and offered strategic inventories at several price points.
PORTABLE VACUUM RAPIDLY HANDLES MOUNTAINS OF STEEL SHOT
Ideal for cleaning large amounts of non-dusty materials such as cast iron, steel, or aluminum chips and sludge, the 1020B industrial vacuum from VAC-U-MAX removes heavy debris in one-fifth of time of manual labor.
MONITORED COOLING FOR ROBOT SPOT WELDING UNITS
Dr. Egon Huefner of Bürkert Werke GmbH & Co. KG explores how the fast detection of leaks in the cooling system enhances the reliability of welding robots.
BEARING FAILURE AND ANALYSIS
Steven Katz of Emerson Bearing shows why the accurate diagnosis of a bearing failure is imperative to prevent repeat failure and additional expense.
REBUILD OR BUY NEW? GRINDING IT OUT
Remanufacture with no prints or buy new at $4 million per machine? That was the question that three different sized 1950s-era cylindrical-type grinders posed for a large crankshaft supplier to the energy, power generation, earth moving, locomotive, mining, marine, stamping and forging industries. The answer?
SUCCESS AGAINST THE MESS
Ed Zitney of SKF Machine Tool Services shares universal lessons learned from four success stories of operations that managed to achieve positive outcomes from the machine tool spindle breakdowns they were encountering.
