Tallying True Costs
When a machine spindle goes down, much more is involved than simply the bottom-line review of a repair bill or the purchase price of a new spindle. Additional underlying costs include more than dollars. Ed Zitney of SKF Machine Tool Services examines what you can do to help save time and money when a good spindle fails.
MAINTENANCE PROGRAM FOR CONVEYORS AND CHIP PROCESSING SYSTEMS
The Managed Maintenance Program (MMP) from PRAB uses customer service field technicians to ensure conveyors and chip processing systems are working properly and at peak efficiency by identifying potential wear parts or components before they become an issue.
POINT-OF-USE: CUTTING OVERHEAD EXPENSES IN TOOLING AND SUPPLIES
With the incredible pressure to gain efficiencies and cost savings wherever and whenever they are available, David Simbari of Supply Pro examines how even small manufacturers can benefit from point-of-use applications.
GEAR OPTIMIZATION SOFTWARE REDUCES TIME TO PART, IMPROVES PRODUCT PERFORMANCE
Excel-lentTM gear/gearbox design and analysis software from Excel Gear quickly determines optimum product parameters for various industries, realizing time savings in hundreds of engineering hours.
Spindles By (External) Design
Ed Zitney of SKF Machine Tool Services explains why understanding how a particular machine tool spindle design will benefit an application can provide a big assist in helping to realize its ideal operation and performance consistent with the job at hand.
CABLE CARRIERS REDUCE AUTOMATION COSTS
Reduce wear and stress on cables and hoses: Check. Prevent entanglement and improve operator safety: Check. Withstand high speeds and accelerations: Check. Cable carriers from igus can do it all and even be pre-configured online, too. Let’s see . . . Added value: Check.
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.
