The Art of the Machine Tool Rebuild

An advanced CNC retrofit package based on NUM technology doubles the accuracy of Klingelnberg SNC 30 hob sharpeners. (first view)
An advanced CNC retrofit package gives a new lease of life to hob sharpeners by doubling accuracy and immensely increases machine productivity.

Machine Tool Rebuilding Takes Center Stage

A technician shoots for alignment precision on a table-design portal milling machine from the 1970s that is being dramatically modernized by Schiess.
Since retrofits, rebuilds or remanufactures typically cost between one-third to two-thirds the price of a new machine, many shops are choosing this route to improve their uptime and availability. Here are some re-cent examples.

Tier 2 Automotive Supplier Retrofits Tailout Feeders for Coil Lines

COE designed the stand-alone tailout feeders to retrofit within the space downstream from the primary coil feeder. The feeder extension is operated through a motorized screw assembly.  During normal operation the primary feed indexes the coil into the die. Once the tailout sequence is initiated, the secondary feeder takes over the feed cycle.
COE Press Equipment retrofit the equipment to three coil lines feeding 500 ton progressive die presses for ARJ Manufacturing.

Next Generation Machine Condition Monitoring

Robust, programmable, and modular technology can be tailored to accommodate a wide range of challenging mill conditions, including harsh operating environments, process parameter changes between steel grades, variable and low-speed equipment, shock loads, and frequent roll changes. Typical applications include main drive roughing and finishing stand gearboxes and pinion stands, rolling mill work and backup roll bearings, and fans, among others. 
The latest machine condition monitoring technologies for steel mill suppliers of flat sheet, coil and structural metals can be tailored to monitor critical equipment assets operating in a wide range of harsh functional environments, process parameter changes, variable and low-speed equipment, shock loads and frequent setups. For shops, there is also virus protection for machine tools.

Servomotors and Drives

HPB Motion Control will exhibit a Direct Drive motor (Torque Motor) and other servomotors and drives.
New AC servomotor and AC drive systems from HPB Motion Control include a Direct Drive Torque Motor, a permanent magnet Linear Servomotor, and an indexing Rotary Table.

Maximum Speed Without Sacrificing Torque

The TMK rotor and stator. Buried magnet technology provides a higher flux concentration that can produce up to 30 percent more continuous torque compared to traditional torque motors of the same size. 
Direct drive motors from ETEL improve the performance of machining centers, milling/turning machines, rotary tables/milling heads, and multi-spindle and transfer machines.

Magnetic Field Sensor For Space Critical Applications

Thanks to its small dimensions of 3.8 x 24 x 3 mm, The BMF 243 is the ideal choice for particularly small grippers and cylinders with C-slots. With its integrated bracket, the sensor is simply inserted into the slot from above, fitting completely into the cylinder without protruding. The BMF 243 is supplied with a cable clip that guarantees optimum strain relief and secures cable routing. 
The flush mounting compact BMF 243 drop-in C-slot sensor for position detection from Balluff offers high performance reserves for cylinders with both weak as well as with strong magnets and offers high repeat accuracy and small hysteresis.
