Machine Features

Built-In Okamoto Conversational Programming System .... developed by Okamoto and based

on our long experience with many different types of grinding applications. This software is based

on the three basic types of grinding ... Form (Plunge), Surface, and Multiple-Step.

The Conversational Programming promotes fast, easy set-up. Saves time...boosts productivity.

When you need more flexibility in grinding, an RS232 Port and PC Card slot

is available for G & M code programming transfer.




“Teach” Input Programming System ... Operator simply moves the grinding wheel manually

to the grinding start position and using an input key teaches that position to the machine,

then he moves the wheel to the cross reversal position and using the input key, teaches that

position to the machine, etc. He then inputs stock removal, air cut, dressing interval, etc.

and the control automatically calculates total movement and all start and stop points.


“Drawing” Input Programming System ... Input the actual dimensions from the

workpiece drawing and the control automatically calculates the cycle sequence.

Built-In Conversational Dress Programming ... is based on the three basic types

of dressing menus -- “Side”, “R”, “V”, and “SLOT”. “FREE” style may also be used utilizing

“G” and “M” Code programming. All of the three basic types of dressing menus have

the capability to dress the following forms.



Vertical & Cross Incremental Feed ... with Multipliers of 0.00001”/0.0001”/0.001”.


Automatic Lubrication...All DXNCP Models utilize a proven Gravity Feed Automatic Lubrication System.

Lubrication oil is pumped to an oil reservoir located at the top of the column and is gravity fed

to all guideway surfaces and positioning screws.


Extended Saddle and Table Ways ... Reduced overhand of the saddle and table at

maximum limits provide long effective life of the machine tool and ensure its built-in accuracy.



Double-Walled Column Construction ... H-Shaped guideways with 3 tapered gibs provide the strength



Double Vee Way Table & Saddle Construction ... providing true tracking, greater table load

support, and longer life of the built-in accuracy.
