Reamers & Boring Tools

The cartridges provides the possibility to design custom tools incorporating the ES-Bore lay down cartridges, allowing customers to receive special tools within a shorter delivery time and at a lower cost. Additionally, the release of the new fine boring cartridges gives customers the opportunity to build their own special tool because the customer only needs an ES-Bore lay down cartridge that can be mounted onto the boring bar being manufactured.

The insert of the Supermini Type 105 system requires only one tool holder for well over 1,000 insert variants. This applies equally to left-hand and right-hand versions. The carbide inserts are available in coated and uncoated versions in different grades for every application including hard machining up to 66 HRC. The patented droplet shape of the cross-section has a vibration-damping effect and delivers excellent repeatability when changing the insert. Internal coolant supply to the insert increases tool life, enhances cutting performance and improves chip removal.

The 3ETECH+ provides improved diameter adjustment accuracy of one micron, making it the ideal choice for customers who need to hold precision hole tolerances on expensive parts. High-production environments such as aerospace, heavy equipment and automotive also greatly benefit from the enhanced digital readout module to be used on Wohlhaupter digital boring tools including VarioBore versatile boring head, 420 (410) series boring heads, 465 (464) series balanced boring heads, 538 (537) fine boring cassettes, custom boring solutions and the newest Wohlhaupter product, the ES-Bore series of fine boring laydown cartridges.

Jack Burley, president and COO of BIG DAISHOWA Inc., took time during Eastec 2023 to highlight a number of the company's products, including tooling technology focused on trochoidal milling, high-precision fine boring heads with digital readouts, and the BIG-PLUS spindle system that is designed so the shank contacts the spindle taper and the spindle face at the same time.n

The exact adjustment of the damper, made of a carbide rod supported in O-rings, is made from the outside via an adjustment screw. Adjustment is achieved by fine-tuning the pre-tension of the O-rings. This allows the boring bar to be precisely set according to the vibration occurring in each application. As standard, Horn offers the tools from stock in the length/diameter ratios 5 x diameter and 8 x diameter.

As with other tool systems, high-performance reaming systems are also subject to demanding requirements. In addition to high process reliability, long tool life and low tool costs, modern reaming tools must fulfil further criteria. These include, among other things, the modularity of the tools. While machining with an HSS reamer is partially limited in this respect, modern reaming systems can be improved by replaceable heads with carbide inserts, modular tool lengths and various adjustment options. These include, for example, µ-accurate adjustment of concentricity and runout. Precise concentricity of the reaming inserts is the path to success. In practice, this should be within 5 µm.

The CBN-tipped mini boring bars feature BX310 uncoated CBN grade that increases the grade's wear resistance when used at low to medium cutting speeds, making it perfect for machining small bores from as small as 2.8 millimeter (.110 inch) diameter of hardened steel parts.
