Advanced Tool Holders and Shrink Fit Technology

In Booth W-1452, Haimer USA (Villa Park, IL) will display many products and technologies, including their new modular interface Duo-λock® for carbide cutting tool heads, Safe-λock® tool clamping system, and Power Mill end mills. Other technologies and products being prominently displayed will be their Power Clamp Shrink Fit Machines, Shrink Fit tool holders and collet chucks, Tool Dynamic Balancing Machines, 3D Sensors, and the Cool Flash coolant delivery system.

The modular interface Duo-λock for carbide cutting tool heads combats the steadily increasing cost of carbide by creating a very stiff, precise interface. The concept of Duo-Lock™ provides maximum stability and stiffness based on an innovative thread with the patented double cone connection and an additional third supporting pilot at the base of the interface. The Safe-λock Clamping System has revolutionized the manufacturing industry by providing reliable pullout protection that withstands even the toughest materials. The Safe-Lock™ principle works like this: Spiral-shaped grooves integrate into corresponding carbide drive pins in the tool holder, uniting frictional clamping force and positive locking. This allows for increased cutting depths and feed rates and doubles metal removal rates. The design provides increased MRR without sacrificing runout or balance accuracy. Now available in an even greater variety of sizes, tapers, and clamping systems.

The Power Mill end mill series is made from K20-K40 grade fine grain carbide developed to be matched with premium Haimer tool holders. These premier end mill geometries utilize unequal flute and helix designs to provide chatter free high-end machining. Power Mill end mills have integrated Safe-Lock shanks for optional use with the Safe-Lock tool holding technology. Its variable helix design provides vibration-free machining and a runout accuracy < 0.0002 in for ultimate precision. Power Mill end mills are precision ground and fine balanced, so shops are also guaranteed consistent and repeatable performance and maximum metal removal rates. An expanded offering is available in inch and metric.

Haimer is the leading developer of inductive shrink fit technology. Their Power Clamp shrink it machines provide 360 deg gripping torque with repeatable balance at the touch of a button. If the triple threat of being easy to use, fast to operate, and having the highest gripping torque isn’t enough, consider the unsurpassed 0.00012 in runout accuracy their shrink fit technology provides. Power Clamp shrink fit machines provide a precise and repeatable tool change every time. The variables that slow down productivity have been removed, such as frequent and lengthy tool changes, unbalanced tool holders and variation between tool changes, which is why more shop owners and plant managers are turning to Power Clamp. This product line has the world’s largest range of shrink fit machines and coils. From the Basic Line to the Premium Line of Power Clamp shrink fit machines, they have the right shrink fit technology for any need.

Their Shrink Fit tool holders provide 0.00012 in runout precision with the highest, 360 deg gripping torque of any holder, along with a repeatable balance (G2.5 @ 25,000 rpm) that gives shops ultimate tool life and surface finish. Shrink Fit technology has no moving part and clamps the same way every time so there is no variation between tool changes. Mini Shrink Fit is the perfect solution for the requirements of micro-machining. Mini Shrink Fit has an extremely slim profile design that eliminates part interference and a 3 deg taper for longer reach capability with shorter tool overhang. It also provides 0.00012 in runout accuracy with the highest balance, quality and stability. Mini Shrink Fit is ideal for the Power Clamp Nano shrink fit machine.

ER Collet Chucks provide more versatility for any application. They are fine balanced at G2.5 @ 25,000 rpm, with high runout accuracy, and come in a variety of lengths and sizes. The Power Series – including Power Shrink Chucks and Power Collet Chucks – are suitable for all applications but ideal for high-performance machining, as well as heavy milling with a high chip volume. The Power Series is designed with more mass for greater vibration dampening and better surface finishes.

Tool Dynamic Balancing Machines provide highly precise measurements to ensure the tools are balanced. Balance is the key to increased productivity. Imbalanced tool holders cause chatter, bad surface finish, shorter tool life and increased spindle wear. This imbalance forces operators to slow down production until acceptable tolerances, surface finish, and machining sound have been attained. This increases cycle times, which in turn reduces machining profitability. Balancing a shop’s entire tooling assembly with Tool Dynamic Balancing Machines ensures longer cutting tool life, reduced machine spindle wear, better surface finish, and the ability to run their cutting tools faster.

3D Sensors make locating the edge in XYZ as easy as 1-2-3. Quickly find the exact positioning of the spindle axis on the edges of the workpiece without the math of calculating the probe’s diameter – these sensors are pre-calibrated to incorporate the probe tip radius offset. With these sensors, zero on the indicator means zero on the machine. Tramming in a workpiece or fixture to a machine, measuring lengths and depths, checking flatness, or aligning work pieces and vise? Easy!

The Cool Flash system guarantees optimal coolant delivery even at the highest rpm. While other delivery systems lack reach, accuracy (and can easily be moved out of place), and cannot be used at high rpm due to lack of sufficient pressure, the patented Cool Flash technology has proven to outperform across the board. The Cool Flash design directs coolant into T-slots at the nose of the holder and works with the centrifugal force of the rotating tool to lead the coolant along the shank of the cutter and directly to the flutes at any speed. This method of coolant delivery minimizes temperature of the cutting edges, eliminates welded balls of chips on the cutting tools, and optimizes runout accuracy, extending tool life up to 100 percent!

Haimer USA is the exclusive North American importer of the full line of products from Haimer GmbH (Munich, Germany), and is also responsible for distribution, sales and service throughout North America.
