Gradient grinder grooves marble easily
Until the introduction of the Gradient GrinderT, kitchen furniture manufacturers and stonemasons had little option but to create drainage holes in marble and granite worktops by hand.
When this Black Forest company was seeking to create an automatic assembly machine for its new high precision worm gears, it had to be certain that the linear motion system chosen would be available in a short lead time, be easy to install and require little or no additional engineering.
Against strong competition, a HepcoMotion DTS Driven Track System met all these criteria, providing a fully integrated, turnkey solution, thereby saving time and costs.
HepcoMotion is the new name for Hepco Slide Systems, a company dedicated to supplying quality solutions for almost all linear automation needs.

The extensive menu of design elements within Hepco's GV3 linear slide programme allows specifiers to create the optimum linear motion system to suit both application and budget.
System building expertise saves money
Designers interested in Hepco's system-building capability could do no better than pay the company a visit.
The worm gears are an integral part of a new generation of electro-mechanical servo steering mechanisms - EPAS systems - developed by IMS Gear.
The new system assembles, tests and registers the gears.
It is a two-row configuration and comprises 34 interlinked stations.
At each of these stations the workpiece supports are driven, guided and positioned by a HepcoMotion DTS Driven Track System.
"One of the reasons why we chose the Hepco system is that it is delivered in just three parts ready for installation," explained Helmut Ketterer, Equipment Design Engineer at IMS Gear.
"And to our surprise it was up and running in just 2 hours." By specifying DTS, IMS Gear saved design, build and test time.
Supplied as table top sub-frames or as stand-alone systems, DTS circuits can be oval or rectangular and with adequate belt support, straight lengths are almost unlimited.
Load capacity per carriage is up to 160kg dynamic load and 400kg static.
Its nearest competitors typically have a maximum load of 12kgs per carriage.
The unique trip latch mechanism on the DTS disengages the belt from individual carriages if drive forces exceed 60N.
The clips remain attached to the cogged belt until they are re-engaged.
At IMS Gear, the maximum torque for the geared motor that drives the DTS has also been limited.
And for increased safety the company's design engineers have fitted additional sensors that constantly check positioning at the individual stations.
For maximum flexibility, DTS users can choose the best drive option to suit the application.
The standard options include three-phase geared motors, worm gears with IEC motor flange or a free actuator shaft; customised solutions are also available.
IMS Gear chose a three-phase geared motor with frequency inverter.
Pulley bearing cassettes are sealed for life and other life-extending features include lubricators on the carriages that apply effective track lubrication.
These are scheduled to be refilled annually by IMS Gear during routine maintenance.
The positioning accuracy required by IMS Gear of +/-0.5mm is within the standard specification of the DTS.
This repeatability is ensured on the longitudinal sides by the system's carriage locking mechanism.
On the front of the installation, additional pneumatic cylinders have been fitted to perform the same task.
"We've had no problem whatsoever with the HepcoMotion DTS," concludes Ketterer. Request a free brochure from HepcoMotion ...
"It has achieved our objective of reduced engineering and just as importantly it was delivered ready-to-install in just 6 weeks from our order - another benefit that augers well for the future.".
