Bumotec product range

Bumotec solutions are a reference in the production of high precision multi-functional machining centers for the complete production of small workpieces.

The range of machines allows Bumotec to satisfy the demands of high volume markets with transfer machines as well as more complex niche markets using single spindle solutions.

In a single production process, 5-axis machining centers perform machining operations on 6 sides using a counter spindle. The goal is to avoid multiple production cycles for machining a complex part or to abandon the use of additional and complementary production units. The process starts from a bar or blank to a finished part produced on an single compact machine, optimizing floor space, part handling, and cycle times thus obtaining the best ratio of productivity.

From an early-stage project, customers will be supported with adapted machine configurations, time studies, and prototypes or small series to ensure a successful project. The application department will study and develop an optimized manufacturing process to get the perfect part in the shortest production time, speeding up part time-to-market as well as enhancing client’s profitability. Combining flexibility, small footprint and efficiency, Bumotec machine lines are known as being user friendly facilitating production parameters, machine setup and training.


SIP product range

Ultra-precision technology applied to the production of industrial applications in Aerospace and Transportation industries.
The product range comprises of horizontal and vertical machining centers, jig boring machines in 3, 4 and 5 axis models.
The essentials of precision start with scraping.
Highly skilled in the process of scraping, SIP specialists perform the finishing geometry adjustments on machining centers using this process, ensuring a machine that is free of all mechanical tension and a stable structure. A perfect mechanical geometry is achieved through intensive scraping. This process has earned SIP the universally acknowledged reputation as an unrivaled builder of ultra-precision machines for many years.

SIP technology is also very useful for Bumotec machines because it is extremely effective in ensuring perfect mechanical precision. We do not stack parts with electronical compensation. The goal is to provide a sound machine geometry but above all a precise geometry through mechanics. It is still today, the only way to ensure excellent repeatability and accuracy over time.
