THE R Series Rack Grinding Machines

Overview: Gear rack and profi le milling like never before.
The machines of the Kesel R-Series aren’t just updated versions of our previous models, they are completely new rack milling platforms. With a brand new bed and slide construction, a world-fi rst twin-table system, a completely new milling head and the possibility to fully automate loading and unloading of parts; the R-Series really is a true game changer.
Available in four size variations from the R2500M up to the R5500M and fi tted with either our powerful F1-HSK or more compact F2-SK milling head, there is a confi guration to fi t every application. The R-Series machines are capable of milling up to module 32 on work pieces with a maximum length of 5,500 mm. Built with the latest SINUMERIK ONE operating system from Siemens the R-Series is equipped for the challenges of today and tomorrow.

特徴

Milling

The R-Series platforms can be fi tted with either the F1-HSK or the F2-SK milling head. With both models built on zero backlash drive units with intelligently controlled power transmission, running smoothness and tooth quality are maximised at all times.
The F1-HSK, our latest model, has the additional benefi t of a HSK arbor-coupling which, when used alongside our new outboard bearing, can deliver up to 350% higher running trueness as well as superior rigidity.

X2T Twin-Table System

As well as the conventional, single table setup, the R-Series is also available with the world-fi rst X2T twin-table system. The X2T comprises of 2 tables, each of which is capable of holding racks half the length of the machine’s maximum capability. This system allows one table to be machined whilst concurrently the second table is loaded / unloaded. The result is up to 2.7 times more productivity! And should the machine’s maximum milling length be required, the tables can be coupled in under 3 minutes for ultimate manufacturing fl exibility.

B-Axis

Helical tooth profi les of up to ±25° can be milled. This axis is available as either manual or driven.

Clamping Systems

The R-Series is available with a wide variety of clamping systems to suit all work pieces including magnets, vises and hybrid solutions.

Automation

All models within the R-Series can be supplied with fully automated load / unload cells in order to allow frictionless machine operation with minimal operator infl uence. With an integrated cleaning system and magazine bays for easy and fast material access the R-Series automation is the perfect solution for maximising ROI.
