BIG KAISER, a leader in premium high-precision tooling systems and solutions for the aerospace, automotive, energy, medical and watch-making industries, today announced the AG90 Light Weight Type with BT30 (BIG-PLUS) taper, a fixed 90-degree angle head.

Part of the BIG KAISER family of angle heads, new AG90 Light Weight Type weighs less than 2kg. This makes it one of the lightest angle heads in the world, and it is therefore compatible with the automatic tool change of small machines.

By allowing vertical, horizontal and angular operations without repositioning the workpiece, BIG KAISER angle heads increase accuracy and productivity. Being able to use just a single set-up, and to easily change the angle of the cutter over a 360 degree range, speeds up production and eliminates errors due to multiple set-ups.

Angle heads enable users to benefit from new capabilities without replacing their current machining center, saving the cost of a new machine.

“The new AG90 combines advanced design features and high quality components, while keeping its weight down to the absolute minimum,” says Peter Elmer, CEO of BIG KAISER. “It complements our existing range of angle heads, which enable customers to find the right solution for almost any application.”

The AG90’s compact design minimizes overhang, which adds rigidity and strength. The minimized overhang also helps to eliminate interference with the ATC and adjacent storage pockets in the tool magazine.

An advanced non-contact seal prevents coolant and particle contamination better than other sealing methods. A unique coolant jacket efficiently directs coolant coming through the stop block to the tool cutting edge, while simultaneously cooling the angle head.

To minimize noise and vibration, the AG90 is made from superior quality components, including hardened and ground chrome-nickel steel spiral bevel gears, super precision hardened and ground spindles, and high precision angular contact ball bearings.

BIG KAISER provides many different types of angle heads such as the AG90 family for milling and drilling or the AGU30 with adjustable angle. In addition, numerous special options can be ordered, and the angle head is available in a wide range of tapers, lengths and designs.

The AG90 Lightweight Type is available now.

ISCAR is introducing the BHD MB50-50X60 – a new boring head with a digital display.

KAISER Precision Tooling, a leader in premium high-precision tooling systems and solutions for the automotive, mil/aero, energy, medical and watch-making industries, recently announced its EWH precision boring head. The EWH has been developed specifically for effective use with exotic materials such as titanium, making it ideal for the aviation industry.

Built for use with coolant pressures of up to 70 bar, the EWH is designed to the highest standards, with an ultra-rigid monoblock construction. This means it can meet the requirements of rigid tools and high coolant pressure that are needed for the efficient machining of difficult work piece materials.

The new boring head is available with a length of 95mm or 155mm and includes HSK/SK/PSC interfaces.

The EWH hydraulic clamping delivers a form- and force-locked connection that clamps the tool holder perfectly, with high pressure around the entire circumference. This is a superior solution to clamp over side lock screws, which have a point and line contact on the circumference.

High coolant pressure of over 50 bar is important to ensure effective cooling, especially when cutting HRSA and titanium work pieces with low heat conductivity. If coolant was supplied with insufficient pressure, it would vaporize, and temperatures would therefore rise – reducing the hardness of the cutting material, and decreasing the lifetime of the cutting edge. The high coolant pressure supports chip breaking and helps achieve enhanced chip forming.

“Its robustness and advanced design make the EWH an ideal solution for the aviation industry, and other applications that include exotic materials,” says Peter Elmer, CEO of KAISER Precision Tooling. “By enabling high coolant pressure and rigid clamping, the new head improves the quality of boring, and saves money by increasing cutting edge lifetime.”
