Hi Vipul

Compare accuracy. repeatability. sturdiness. programmability. acceleration , deceleration , tool-changes. max speeds , drive mechanism.

What controller are they using?

I would say prepare typical test files of what you need it to do and get demos (time and observe).

The fastest machine at the quality you want should win.

The CNC driller-routers can do either or both operations in combinations.

Drilling is the operation of producing holes as specific locations.

Routing is the operation of producing grooves or similar cuts, with or without holes in the grooves.

The machines you are bidding on should do the job. If you require high accuracy of location you may need a CNC-Brain, <SafeguardRobotics.com> temporarily off line at the present time.

If you are asking what the machines are then contact the seller or manufacturer.

If you are asking what the difference is between the two then...

Drills are only to be used for making holes axially. The spindle bearings are not designed for the radial loads that occur during routing. I cringe when I see people use positioning tables on drill presses to cut slots and key ways. You can get away with this by making light cuts. But do not get in the habit as you will gradually become more impatient and aggressive. Eventually you will ruin your spindle.

Routers have spindle bearings that allow them to handle axial and radial loads.

Hendrik's pretty much got this one - just wanted to add that you might want to ask if one of folks working there has experience with similar machines, and solicit their input. Some subtle diferences that may be particular to your operation could make more than subtle differences in daily operations.

Buy the driller/router. You can not only drill, but route the perimeter as well.

Verify the model number. Excellon routers model number ends with an R.

Let me know how manny spndles and the RPM. Routers max speed is 60 000 and driller speed is 80 000 RPM
