DrillMeister Range Expanded

DrillMeister incorporates a unique self-locking interface that enables simple and secure drill head exchange. Since drill heads can be replaced without having to remove the drill body from the spindle tool setup time can significantly be reduced, eliminating presetting, offset, and touch off of the replaced tool.

UNISIG highlights benefits of trepanning

UNISIG, Menomonee Falls, Wisconsin, demonstrates why trepanning is beneficial when drilling deep holes that are too large for high-pressure coolant drills or gundrills. Utilized in the aerospace, defense, material production, as well as oil and gas industries, trepanning reportedly offers higher productivity in many applications and uses less power than other drilling strategies.

EWE Digital Boring Heads

Due to the small sizes of these boring heads, the digital display will no longer be present on the head itself, rather the adjustment value will be shown on a separate mobile device or tablet that has the BIG KAISER App installed. Once connected to the head, the App also can be used to set the target diameter and tolerance. This information will stay assigned to the specific head connected until it is changed by the operator. Along with the last measured cut information (entered by the operator each time an adjustment needs to be made), the App can show the adjustment required to get the head set to the target diameter. n

EWA Automatic Adjustment Fine Boring System

The EWA68 boring head has a travel range of .866" on diameter, and with the smallest insert holder, it covers the range of Ø2.677-3.543". This means that similar-sized bores on the same part could be produced with a single boring head. With the addition of two larger insert holders, the range can be extended up to Ø5.197".

An engineered approach to deep-hole drilling

Books have been written on how to produce deep holes using milling machines or lathes, but trying to drill deep holes with depth-to-diameter ratios greater than 15-1 (D-d) using standard machining centers often leads to frustration, costly scrap and poor use of shop resources.

BoreMeister Series Setting Device

Setting the tool to the correct center height is one of the important factors to achieve the right dimension tolerances and surface integrity of the component. The new setting device enables easy, systematic, and accurate settings of tool center height. Its serrated interface with a magnetic locator in the center makes attachment and detachment to the tool body easy and accurate. The setting device comes in two sizes: AVC-SET16-25 covers BoreMeister diameters 16, 20, and 25 mm and AVC-SET32-60 diameters 32, 40, 50, and 60 mm.

DrillForce-Meister Line With Smaller Drill Diameters

DrillForce-Meister incorporates a unique seat design that enables easy and swift drill head exchanges, while maximizing the clamping security, making drilling easy on curved surfaces, inclined exits, or components with a stability problem. The seat is designed with a maximum possible contact surface to hold the drill head in place for secure stability during demanding large-diameter bore drilling with the IT9-IT10 hole tolerance.

SNG Coolant-Through Holders

Designed for the internal grooving of bores with diameters as small as 8.0 mm (.315″) up to 24.0 mm (.945″), while promising reliable chip evacuation. The shanks are made of either steel for economy or tungsten carbide for long reach areas where tool steadiness is vital. Virtually eliminate chip nests, reducing part scraps and machine downtimes, while improving machining efficiency.
