Parallel Keepers - Separators are available from Sta-put123.com. They are hardened and ground, plated, 0.0002" flat, and parallel.

Kurt's new KHU6 hydraulic unit comes ready with both single- and double-acting capabilities providing a convenient option to the users preferred clamping method. Single-acting method uses hydraulic clamping and spring return for unclamping. Double-acting capability uses both hydraulics to clamp and unclamp for faster, more precise setup.

Lexair's new Flex Grip closers are designed for versatility and efficiency, and they are proven to boost productivity for a variety of machining operations including 5-axis, rotary indexer and stationary applications. The manual/hydraulic closers are clamped through a screw pump with a spring return opening.

WDS Component Parts Ltd. has extended its offering of medium-tensile T-bolts with the addition of a forged steel option that provides more strength and wear resistance than mild steel. These are aimed at applications where the high strength of low-alloy, high-tensile steel bolts is not appropriate.

If you're lucky, the veterans in your shop will take a rookie aside and pass on their hard-won knowledge of good machining practices. Most of this information is priceless. But some of it … not so much. For example, there are a lot of myths about balancing out there that, if not refuted, can cost your operation a lot of lost time and money. In this article, Haimer USA LLC addresses these misperceptions and offers a more factual view of best practices for balancing toolholder assemblies.

Using Finite Element Analysis (FEA), Kurt designed and optimized the new XL6 XtraLong vise to be better performing than its predecessor vise the 640XL. Boasting a 14.50" opening, the XL6 manual vise clamping capacity is .50" more than the 640XL vise and accomplishes the increase even while the over length was reduced by .42" to 24.10".

Top jaws should be designed to hold the workpiece as close to the chuck face as possible. Excessive jaw height reduces the effective gripping force available and is detrimental to accuracy.

GTI Spindle Technology says spindle repair and rebuild is the heart of what the company does, and it prides itself on being able to handle any spindle that comes through the door. All spindles can be repaired, though the associated cost for some can eclipse that of a brand-new spindle. When this happens, GTI Spindle Technology turns to Peron Spindle for a replacement.
