About A-1 Engineering
and the "Ultimate"
5-Axis Work Stop


A-1 Engineering manufactures tooling for the machine industry. Besides making the 5-Axis Work Stop tool, we also manufacture specialized replacement parts and customized machinery.

The original idea for the 5-Axis Work Stop began as early as 1995 when machinist Rudi Pankratz began his quest to develop a truly useful and practical work stop for CNC machine centers, milling machines and drill presses.

Rudi was frustrated with the common and continuous problems associated with most types of work stops on the market. As the owner/operator of a machine shop, Rudi's intent was to design a work stop tool that would be versatile to fit many different machines and applications, quickly installed with fast set-up time, and having maximum access, accuracy and rigidity.

Following two and a half years of research and development Rudi's design was perfected. Unlike all previous work stops, his work stop contains a 5-axis pivoting and positioning rigid locking system that attaches to any standard table on CNC machine centers, milling machines and drill presses. Rudi has developed the ultimate work stop and the solution to problems faced regularly by machinists and the machine industry.

Its universal and quick machine installation, versatile job application, and precise access and accuracy, set it apart from any other type of work stop on the market today. Truly innovative and unique.

The 5-Axis Work Stop is made of high-quality aircraft aluminum and stainless steel and is manufactured on CNC machines.

The 5-Axis Work Stop tool is presently marketed throughout North America and internationally. The majority of customers are manufacturers of precision products.

Rudi continues to work on innovative ideas as head of research and development for his company.
