SP2005 Automated Stamper Punching System
Description
SP2005 is a highly accurate automated punching system designed to service the needs for
precision alignment of the data area to the physical center hole. In manufacturing or the
injection molding process, the stamper eccentricity needs to be as low as possible to allow
require the entire error budget to be within specified range. By having a highly precise
punching alignment process and keeping eccentricity as low as physically possible, the
molding process (where mass production takes place), is allocated the most room for error.
The SP2005’s advanced digital imaging system that originated in the US aerospace industry
is the key to performing highly accurate alignment of the data center to the punch hole. The
same technology that allows guided missiles to recognize ground pattern is used to
recognize pit and groove structures at high speed to identify the data edge. As the stamper
is turned the edge movement indicates the run out between the physical center and the data
center. When the 2 centers approach alignment, the run out approaches 0. The minimum
achievable eccentricity is ½ the track pitch since the data edge is composed of a spiral.
This means that the higher the density or closer the track pitch, the more accurate this
system will be.
Why is eccentricity important?
As transfer speed escalates exponentially to deal with faster loading time or transfer time
from the optical media, the linear velocity or rotational speed also is increased. As rotational
speed increases, the pickup on the playback or recording device must move much faster to
properly track the single groove or data track. When the eccentricity is high, this groove or
track swings wildly from side to side and the head must move farther to keep up with the
tracking. If the eccentricity is low, the track appears to be stationary and tracking is vastly
more improved. Better tracking means better seek time and better playability for your media.

For the job information, each stamper data are stored according to the customer’s tracking
information along with the actual inline eccentricity measurement. As data collect, a customer
can tabulate how many stampers had been punched per shift or day or week or month and
how well! This is a first in the industry. The data can be exported out to a central database
and the job information for the punch can easily be incorporated into the central file. The
summary report can provide valuable information to the operational team as a feedback tool to
improve productivity.

The interface is simple, process oriented and large buttons are used to draw the operator’s
attention to the key functions. For example, a job can simply consist of the following:
1. Click <HOME>
2. Set stamper on the stage
3. Key in production tracking information
4. Click <EXECUTE>
5. Wait until the punch is finished
6. Remove the stamper
Other functions can allow troubleshooting and control at each step.

| If manual control is needed, the buttons are readily available. All the hard work or intensive be activated for ease of troubleshooting if needed and will log every command issued by the machine. With an automated digital imaging and inline testing system, efficiency is vastly improved without having to sacrifice quality. |
