Introduction
Dear customer:
We feel greatly honored and express sincere gratitude to you for using our products!
This manual describes matters concerning interface and operation of HNC-8 CNC milling system in detail.
However, we cannot describe all the matters which must not be done, or which cannot be done, because there are
so many possibilities. Therefore, matters that are not especially described as possible in this manual should be
regarded as “impossible” or “not allowed”.
In order to ensure safety and normal use of the product, please thoroughly read this manual before installation or
use.
Safety warning
Improper operation will result in a safety accident, so operators must be qualified for transportation, installation,
commissioning and machining.
Copyright
Copyright of this manual should be reserved by HNC. Any units and individuals' publication or duplication should
be deemed as illegal behavior and we will hold them accountable.

HNC-8 System Operating Manual (Milling Machine)
1 Overview
HNC-8 CNC milling system includes HNC-808Di-M, HNC-8Di-M,
HNC-8Ai-M, and HNC-8Bi-M. This manual is based on HNC-808Di-M
panel type. In case of discrepancies, please refer to the specification
provided by the machine tool manufacturer.
1.1
Basic Operation
HNC-808Di-M system is a CNC controller for CNC milling machine.
The MCP panel is furnished with 6 working mode keys "Jog, auto, single
block, MDI, incremental/handwheel, and reset". During operation of
CNC lathe, function description and content of these 6 working modes
are shown below.

1.2
Basic Function
To complete different work under different working modes,
corresponding application functions should be used. The NC panel of
HNC-808Di-M CNC device is furnished with 6 function keys "machining,
setup, program, diagnosis, maintenance and user-defined (MDI)". Every
function key corresponds to a group of function sets. User can select
corresponding functions and interfaces form the function set through
function soft keys (for soft key function menu and display interface, refer
to chapter 3 "Display interface").

Description:
* While configuring standard version function set, for ease of operation,
some identical soft key functions are configured in different function
sets (function set can be configured according to user need)
**For other series than HNC-8 Di series, user-defined key is often set as
the MDI function.
1.3 Basic Display Interface
HNC-808Di-M system can realize different application functions through
function keys and function soft keys, and display corresponding
interfaces. The display interface of this system mainly includes
machining display interface, program selection and editing interface,
machining setup interface, parameter setup interface, and fault alarm
display interface, and so on.
The operator can know the current status and information of system
through interface, or have a man-machine conversation in the
conversation area to realizecommand input, parameter setup and other
operations.
All interfaces are briefly introduced based on HNC-808Di-M standard
configuration.
1.3.1 Machining Display Interface
The machining display interface enables the operator to observe the
machining process and has 4 display forms: big character coordinate +
program, joint coordinate, graphics path + program, and program. These
4 interface can be switched through 『Display switch』 soft key.
