BTA COUNTER BORING MACHINES FOR FRONT FORK

CRAFTED WITH PRECISION AND DETAIL

The BTA Counter Boring machines are WIDMA’s specialized machines that cater to the needs of the front-fork manufactures of scooters and motorcycles.
We have supplied several machines of this series to customers in India and Southeast Asia over time. Extensively designed and tested, these machines are designed to meet the critical accuracies of bore size, surface finish (0.1-0.2 µRa) and geometrical accuracies as required on a typical outer tube component. A unique feature of the machine is the option of both horizontal and space saving vertical configuration, making it compact.

The BTA Counter Boring CNC machine has linear motion guides for slides and a ball screw for linear slide movement. The variable frequency drive ensures spindle speed variation. The high-pressure coolant system improves the manufacturing quality, reduces the manufacturing cost, and helps increase the product life. Some of the other features include a chip conveyor, a fully enclosed sheet metal guard, panel cooler, a hydraulic powerpack (HPP), and a nylon disc or a compact band filter for fine filtration

Along with the machine, we also offer tools and accessories such as BTA tubes and heads, guide bushes, coolant retainers, and damping bush. WIDMA also provides optional features that can be added on request such as A.C. servo motor for spindle drive, refrigeration unit for coolant tank, mist collector system, and paper bank filter.
