The Quickpoint cylindrical grinding machine from Junker possesses capacity and flexibility through a single clamping process.
Sisamex processes an average of 160,000 gear shafts per year in Mexico with the Quickpoint high-speed grinding machines. The production facility is located in General Escobedo, Nueva Leon, an industrial center in Mexico.
Sisamex produces gear shafts with maximum precision while reducing auxiliary process times; this ensures an effective production with low handling costs.
“This machine unites precision and maximum flexibility, as the cylindrical grinding machine is versatile in use and has an enormous capacity,” said Francisco Vélez García, who is responsible for processes at Sisamex.
One of the technical advantages is the grinding of the gear shaft in a single clamping process. The gear shaft is clamped between centers for processing the outer diameters and end faces. The CNC tailstock withdraws for processing of the inner cone, with the gear shaft being held and guided by the steady rest. The industrial company processes different gear shaft workpiece families on Quickpoint, showcasing the Junker grinding machine’s versatility.
“Various workpiece types are swapped several times a day. We can flexibly retool the grinding machine without complications and in the shortest possible time. The temperature in the plant is controlled at 23 to 26°C. This ensures a stable grinding process with the in-process measuring systems used by Junker. A high process capability (CpK) is achieved by the use of the Junker grinding machine,” said Vélez García.
The grinding machine is equipped with an internal loading gantry for loading and unloading. Switching to new workpiece types on a Quickpoint is possible at low costs, reducing auxiliary process times to a minimum.
“The Quickpoint grinding machine is the heart of production, which is why fast service is very important to us. It was possible to significantly reduce downtimes with Junker’s technical support,” Vélez García said. “The installed components of the grinding machine are customized, variable, and of the highest quality. Using them saves Junker additional maintenance costs. “With Junker’s grinding machine, we have reduced production costs and optimized the grinding process.”
