JUNKER Brings Innovative Solutions for Compressor Screw Rotor Shaft Machining
JUMAT 6L Integrated Grinding Solution-JUNKER's latest research and development achievement, completes the overall grinding of the screw and rotor shaft with the highest precision. This fully automated grinding machine not only exceeds user expectations, but also brings innovation to the entire grinding market.
As the leader of the CBN grinding process in the global market, JUNKER has set a new milestone in the field of screw rotor shaft manufacturing.
The partners of your precision grinding simplifies the grinding process and develop a flexible and efficient grinding scheme : all key dimensions are measured online, including profile scanning and automatic size correction, which only achieves the highest quality for you.
Realizing the highest precision fast and efficient processing
Since 2011, Sullair LLC., located in Michigan City, Indiana, USA, has become a user of JUNKER grinding machines. Sullair air compressor has made major changes to its surface treatment process, eliminating the requirement of rotor pairing, and greatly improving the efficiency of the compressor.
In the past, multiple grinders and multiple clampings were required to complete the grinding of a rotor shaft. Before grinding the groove, the diameter and end face of the rotor shaft must be ground on the JUNKER QUICKPOINT point grinder.
Now, with JUMAT 6L, all machining tasks can be completed with only one machine tool and a single clamping.
In addition, in order to change models faster and control processing quality, the machine tool performs online measurement of key elements and makes corresponding automatic corrections, so that the highest quality can be produced without manual intervention.
JUNKER has developed the ability to automatically measure complex spiral groove profiles and adjust the dressing path of the CBN grinding wheel.
High-efficiency precision grinding
Dressing is very important because the pressure of the grinding wheel varies with the contact area on its profile. The incorrect profile must be trimmed, so that a perfect workpiece can be processed.
For this, the JUNKER grinder is familiar with it and achieves excellent accuracy, with a lead error of +/-3 microns and a profile error of less than 6 microns.
JUNKER uses intelligent processes to ensure high productivity
For rough grinding and fine grinding of different spiral groove profiles, the machine tool is equipped with a grinding wheel replacement system.
The machine program can call the correct grinding wheel and manage the life of the grinding wheel. If a piece of grinding wheel has reached the end of its service life, the control system will request a replacement of the grinding wheel and remind the production manager to purchase a new grinding wheel.
The workpiece is transported to the machine tool by a fully automatic conveyor belt. Load the workpiece into the machine tool through the internal gantry system. Therefore, the safety of the entire system is guaranteed, and the grinding can be carried out with no added mineral oil.
Economical, intelligent and precise
The JUNKER rotor grinding technology requires only one clamping to complete the efficient grinding of the compressor rotor shaft, achieving the highest efficiency and maintaining stable quality.
The JUMAT grinding machine from JUNKER is a revolutionary new solution.
