Proper tooling maintenance is critical to produce high quality parts, increase machine uptime and extend tool life.

RSM Sharpening System ensures the proper result for every sharpening operation.

With RSM easy-to-use touch screen interface, powerful high-output motor and ability to accept any tooling style, keeping your tooling in optimal condition has never been easier!

Drive System:

PEXROTH/THK/HIWIN imported linear guide rail and ballscrew. Imported SKF/NSK bearings.

Control System:

Imported servo motor, Imported PLC, 7’’ touch screen


lFully enclosed work area ensures safety.

lDoor interlock prevents operation with door open.

lAbrasive mist contained during sharpening process. Keeps work area clean while eliminating slip hazards. Keeps abrasive sharpening mist out of the air and off of other expensive machinery.

lCE and QPS certified.


1.A wide variety of punch press tooling systems are fully compatible with the Rsm Sharpening System.

2.Small diameter punches can be ground without breakage.

3.Rooftop shear may be sharpened easily by using the graduated tilt mechanism.

4.The machine even sharpens complicated whisper shears on Trumpf-style punches.

5.Large station dies can be sharpened quickly with high quality surface finish

Problems for most of sheetmetal factory

l  Passivated tool core will decrease the punching quality

l  Return of material is a common condition caused by disqualification punching grinding

l  Tool change time increased caused by bad grinding quality

l  Machine working time becomes short caused by short life tool

l  Grinding cost increased

l  Storage cost increased caused by purchasing 2-3 sets tooling

Automatic CNC grinding machine can solve all the above problems:

Our machine is mainly for the grinding of CNC punching machine, it can be achieved by setting the parameter on the touch screen, max grinding diameter is 160mm; punch holder can be installed on the rotary working table; multi-channel cooling water device; our grinding structure use imported linear guide and ballscrew, servo motor and with high accuracy; CBN good quality grinding wheel with high induction, and can improve the tooling life time.
