Carlton Die Castings, a Scottish die casting and CNC machining specialist, provides quality and service to ensure that castings arrive on time every time with no rejects

Ironwood Designs, a San Jose, CA-based designer and manufacturer of wooden gun stocks, has more than tripled since replacing a manual pantograph with a four-axis CNC router. Made of high-quality hardwoods, Ironwood Designs' products are purchased by individual gun owners, gun dealers and firearms manufacturers to replace the inexpensive plastic or softwood stocks of many imported military guns such as the FN-FAL and the AK-47. Ironwood Designs also sells a four-piece wooden set that includes the butt stock, pistol grip and an upper and lower hand guard.

A CNC mill or lathe is just a pile of metal and wires until the g-code - the software - begins to drive it. Therefore, any improvement in the software that runs a machine will have a direct improvement in the productivity of that machine.

This capability can save secondary bending operations or even the need for a second bending machine.

Many CNC users have two or more highly similar CNC machines made by different machine tool builders. Depending on work load, most need to run the same jobs on any one of the similar machines at any given time. Say, for example, you have two 20-horsepower, eight-inch chuck, turning centers. One is made by brand X and the other by brand Y. As each job comes up you would probably like to run it on whichever turning center frees up first.

This vertical Nd:YAG laser drilling machine for 12'' cube parts (300 × 300 × 300 mm in X, Y, Z), the model VLD-300, was developed by Mitsui Seiki (Franklin Lakes, NJ) in collaboration with several aerospace engine component manufacturers who expressed a need for a higher-speed, more accurate laser-drilling machine than was currently available.

Axial chip thinning is a way of "cheating," sort of, to achieve a higher feed rate. At least it seems like cheating. Under the influence of chip thinning, the chip thickness no longer equals the advance per tooth. Instead, the chip is smaller-meaning the rate of advance per tooth can increase.

The need to create small, precise holes with high depth-to-diameter ratios in hardened materials is on the rise. Such holes are used as start holes for micro wire EDM work for machining miniature molds and stamping dies. They may also be found on small vacuum plates, turbine blades, and miniature medical and electronics components that require tiny, burr-free holes.

IMS51 series ac bipolar drivers are CE compliant to meet safety protocols when powering ultra high torque step motors. Output current can be selected as 1.4 A/phase or 2.8 A/phase, depending on requirement. With basic step division of .72[degrees] full step at 500 steps/revolution and .36[degrees] half step at 1,000 steps/revolution, driver suits NEMA size 17, 23 or 34 5-phase step motors. Requiring no power supply, units operate from 120 or 220 Vac.

Rapid manufacturing and prototyping specialist, Ogle Models, has introduced a flame retardant plastic to the range of materials that it uses to produce components for customers. Designated PA 2210 FR, the powder is produced by EOS for use in its laser-sintering machines, of which Ogle operates three, two of which were bought in June 2008 as part of a £1 million investment.

Jonathan Schwartz has found a way to turn math concepts into real problems. A math teacher at Colfax High School for 13 years, Schwartz believes students learn not only in a traditional classroom, but also when they work with their hands.

Changes that address the leadtime required to make a mold tend to focus on the machining cycle. A faster machine following suitable tool paths can allow machining cycles for cores and cavities to proceed considerably faster. However, saving time from these cycles can only go so far; significant time is also lost elsewhere. Making a mold demands not just machining time, but also programming time-and much of that programming may not even involve the core and cavity.
