New Emuge Tap Holder Boosts Tool Life And Optimizes Thread Production On Machines With Synchronous Spindles.

NORTHBOROUGH, MA ( March 1, 2002 ) - Emuge has introduced an innovative Tap Holder, specially designed for thread cutting on CNC machines using synchronous spindle control systems.

The holder, named "Softsynchro", features a small compensation range in compression and tension of about .020" ( 0.5mm ), designed to compensate for spindle overrun and inherent inaccuracies in synchronous tapping cycles. Inaccuracies occur with minimal pitch differences between spindle and tap, which leads to high thread flank friction forces. Softsynchro works like a damping element between the spindle and tap, making up the differences in pitch, keeping excessive axial forces and inaccurate cutting of threads to a minimum.

"Test results using Softsynchro with Emuge Taps in thread production have been very impressive," said Peter Matysiak, President of Emuge. "Depending on the application, it is possible to increase tool life to 150 %, with significantly improved thread surface quality as well.

Other Softsynchro capabilities contributing to high performance thread production are superb runout accuracy similar to a rigid tool adaptation and the ability to clamp the tap rigidly through collets with square adaptation.

Softsynchro also accommodates internal coolant supply (up to 700 psi) for machines with spindles that have this feature. Internal coolant, exiting through axial boreholes or along flutes in the tap make thread cutting very efficient, as chips wash out through the threaded hole while optimum lubrication is achieved.

The Softsynchro Holder allows taps to be adapted through the use of 3 different types of Emuge Steel Collets; standard according to DIN 6499 (Type ER), with square drive (TypeER/GB) and with length compensation in tension direction (Type ET-1-PCM).

Emuge, part of the 1,000+ employee German parent company Emuge-Werk Richard Glimpel KG, has been the product technology and performance leader in their field for over 75 years. The company manufactures an exhaustive line of taps, end mills, thread mills, holders and attachments, over 100,000 items sold through distributors worldwide.

North American Headquarters of Emuge are located in Northborough MA USA , where applications solutions are managed and over 10,000 types of cutting tools and accessories are stocked for prompt shipment. Emuge also offers end user technical support through a network of in-the-field engineers with extensive tooling experience.
