Laser Marking Equipment
Trumpf, Farmington, CT, offers a complete turnkey solution for an ultrashort pulse laser in a marking station. The TruMicro Mark 2000 laser’s ultrashort pulses make it possible to mark metals with a particularly deep black color and with virtually no heataffected zone. This cold processing enables fabricators to mark the material in a way that will always remain corrosion free, saving both time and money traditionally required for refinishing. In addition, the ultrashort pulses enable it to mark chromed plastic surfaces without removing any plastic. Several control loops, in conjunction with a patented fast external modulator, guarantee maximum process stability and the set pulse parameters for each individual pulse.

High-Torque Retention Knob
A high-torque retention knob from JM Performance Products, Fairport Harbor, OH, prevents toolholder deformation, a common problem in milling centers. Retention knobs can present critical productivity issues for manufacturers due to toolholder expansion. The high-torque knob addresses this problem by maximizing the length of the knob to fit the toolholder. As a result, all thread engagement occurs in a region of the toolholder where the diameter is large and where there is correspondingly more material to resist deformation. When properly installed with a retention knob socket and torque wrench, the patented design prevents toolholder deformation.

RFID-Coded Welding System
Herrmann Ultrasonics, Bartlett, IL, has integrated an RFID reader and an optical sensor into its ultrasonic welding system to ensure safety and security when changing welding tools during the production process. An RFID reader has been integrated into the tooling to guarantee that the right tool is installed for the production. The reader is built into the sonotrode as well as the fixture. The system automatically associates the correct parameter setting for parts to be welded with the installed tooling. The optical sensor verifies that the correct part in terms of shape and color has been placed into the fixture before each ultrasonic welding process.

LSR Equipment
Graco Advanced Fluid Dispense, North Canton, OH, has launched new barrel stack designs for its F-5 and F4- 55 two-component liquid silicone rubber (LSR) injection molding meter, mix, and dispense equipment. The updated barrel stacks are available in both multi-pass and single pass designs. The new stacks are easy to clean and assemble and have no tapered national pipe thread (NPT) threads. The new barrel stacks use plastic molded mixers, which stack upon each other. These mixers prevent the sidewalling problem that may occur with older stainless steel mixer designs caused by repeated removal and installation. The plastic mixer also does not suffer from installation damage due to a tight tolerance between the hosing and mixer. Greater clearance makes the new barrel stack easier to clean by reducing thread galling.

Segment End Mills
Emuge Corp., West Boylston, MA, has introduced new end mills designed to enable substantially more material removal with fewer passes in five-axis machining. The circle-segment cutters are ideal for machining turbine blades, impellers, and blisks, and for use in mold making applications. They feature unique forms with large radii in the cutting area of the mills, allowing a larger axial depth of cut during prefinishing and finishing operations. The solid-carbide end mills are offered in four geometries: barrel-shaped, oval form, taper form, and lens shape. Oval and taper form mills are ideal for curved shapes such as blades or straight-walled pockets, freely engaging more of the cutting edge. Barrel design mills provide highly effective flank milling to the sides of spiral grooves and similar applications, while lens shape mills are best for narrow channels or in lands on molds.
