Friction free linear movement in a harsh working environment
The fit and forget quality of HepcoMotion linear motion components is an important contributor to the reliable performance of a uPVC sash centraliser system for uPVC manufacturers. This innovative system is available different variants and designed for harsh production environments.
A sash centraliser system, developed by F.W. Frost, is a manufacturing fixture that allows a uPVC door to be mounted within the frame very accurately. The company manufactures many variants but a common feature of each of these innovative fixtures is HepcoMotion linear motion products.
HepcoMotion LBG linear ball guides are responsible for carrying the two symmetrically opposed sliding frames of the centraliser, maintaining their co-ordination throughout the range of motion. They provide low friction movement, an important feature as the frames are manually positioned.
The three arms that position the central clamping units are supported by a HepcoMotion UtiliTrak guide and the system also uses HepcoMotion Pacific Bearings. These provide low friction guidance to pneumatically operated lifts that elevate the door from its frame for hinge fitting.
To support and guide the multiple clamp heads, positioned along the length of the centraliser to clamp the frame and the sash independently, F. W. Frost specified HepcoMotion GV3 single edge linear slides.
"These slides provide a very smooth and reliable solution," explains Tony Bayliss, the company's Sales Manager. "The centraliser is manually operated and used repetitively, so smooth and easy movement is vital in preventing operator fatigue."
Another factor governing F. W. Frost's selection of the HepcoMotion GV3 system is its ability to provide consistent and reliable operation in harsh manufacturing environments. The V-principle that is the trademark of the HepcoMotion linear motion concept is a key factor in this regard as it provides an effective self-cleaning action.
Swarf from drilled mounting holes and fasteners that have been misplaced are characteristic of the sash centraliser's working environment. So the ability of HepcoMotion GV3 to prevent the ingress of debris onto the contact faces is vital to smooth movement and the system's suitability for use in a high production environment.
