The Advantages and Improvements of Using Supertec Machines
Since incorporating Supertec machines into their operations, Duval has seen several key improvements that have directly impacted their grinding performance:
CNC Grinding Advancements and Automation
The transition to CNC grinders such as the G20P-50CNC and G32P-60CNC has transformed grinding operations by significantly reducing manual setups and increasing precision. Features like automatic dressing and size compensation help maintain repeatability and minimize operator error, demonstrating how CNC technology drives quality assurance and productivity in machine shops.
Optimizing the Grinding of Complex Geometry and Tough Materials
Modern precision manufacturing demands versatile grinding capabilities, such as handling multiple diameters and complex geometries in a single setup. This is especially critical when working with tough materials like Inconel, common in aerospace components. Frequent wheel dressing—often every few parts—is essential to maintain geometry and tight tolerances. By combining automated dressing with skilled operator adjustments, manufacturers ensure consistent quality and reduce scrap in high-precision applications.
Supplier Relationships as a Critical Success Factor
Working with Supertec, Duval gains access to quick deliveries of parts like wheels, fixtures, and service of programming, which helps reduce downtime and accelerates job turnaround.
Programming Support and Ease of Use
Duval mentions the ongoing programming support from Supertec, with quick, responsive assistance, exemplifies how technical support and easy-to-use software can dramatically shorten the learning curve for complex CNC equipment.
Recommendation for Supertec
Duval speaks highly of Supertec for companies and shops looking to elevate their precision grinding operations. Supertec’s commitment to quality and service aligns perfectly with Duval’s mission to provide top-tier grinding solutions to their clients.
With the reliable machines and customer support, Supertec has been a trusted partner in Duval’s journey toward greater success. Duval is confident that their continued partnership with Supertec will enable them to maintain their competitive edge and deliver outstanding results for their customers.
“I wish I could fill up my business with more of these supertec machines. They’re really easy to run and program. If we’re having any issues they’re more than willing to come down and help us out. I’ve had these machines for a couple of years now, and I would definitely highly recommend purchasing these Supertec Machines”
