Presetting
Expands Toolroom Capacity
Heinz
Kaiser AG (Rümlang, Switzerland), for more than 50 years an
international manufacturer of high-precision boring tool systems,
has been in the business of developing and producing high-precision
modular tooling systems for boring, drilling, milling and tapping
applications.
The company has more than 100 employees and a business that has been constantly
growing serving its customers in the automotive, aerospace, machine tool,
mold and tool, and job shop industries.
Heinz Kaiser enjoys licensing agreements with BIG Daishowa
Seiki Co. Ltd. (Osaka, Japan). Under one licensing agreement, Heinz
Kaiser manufactures the BIG-PLUS tool holding system. Under another
licensing agreement, BIG Daishowa Seiki manufactures Heinz Kaiser's
precision boring tools for the Asian market.
With its business growing, Heinz Kaiser's team of engineers
and operators began looking for ways to increase the company's
toolroom capacity. Knowing the importance of tool-presetting and
the impact it has on setup time, the company, which had been presetting
its tooling for more than 40 years, began looking for the newest
and most accurate technology to complement its existing presetting
system.
The evaluation of tool presetting and measuring equipment
was spearheaded by Heinz Kaiser's Peter Feller, plant manager,
and Thomas Terstiege, production manager. Their objective was to
identify and incorporate a system that would work with the company's
existing tooling and could easily communicate with its existing
Benz TDM tool management software.
The company purchased a tool presetter and measuring system
from Speroni S.p.A. (Pavia, Italy). The system selected was a fully-automatic
Esperia STP 46 CNC system with ProVision software that promised
the level of accuracy and repeatability required to meet critical
tolerances, delivered with user-friendly, simple programming software.
"We worked with Heinz Kaiser to deliver a system that
would meet their needs and could be integrated into their existing
setup," explains Speroni's international product manager,
Michael Müller.
The new unit offers both manual and fully-automatic operation.
Manual mode allows tool measurements to be made quickly and easily
on single tools during prototyping. Automatic mode can be used
for all tools that are set up in the database.
Another advantage of the automatic CNC/vision system is
that no matter which operator is using the system to measure whichever
tool, the results are always the same. This leads to an improvement
of tool life and part finish due to the accuracy and consistency
of the tool measurement.
On manual units with projectors, focusing is set by the
operator, leaving more room for variation and errors. Because the
Speroni Esperia STP 46 unit has automatic focusing, the possibility
of human error is removed from the measurement process, and repeatability
and accuracy are improved.
Heinz Kaiser, Benz TDM, and Speroni supplied the required
input for the installation and Speroni and Benz TDM made the necessary
adjustments to their systems to integrate the presetter system
into the Heinz Kaiser facility.
"Integrating the Speroni software with our system was
a shared effort," comments Andy Kolb from Benz TDM. "The
software was very accessible for me to program the interface and
exchange the data." Similar ventures with other companies
usually are more complicated and take much longer, he adds.
The collaboration of the companies helped achieve clear communication between
the two systems. Now, tools in the database require no additional definition
once they are entered, and they can be measured right after being selected
from the tool list. Furthermore, if a more complicated tool contour is
defined with the Speroni software, the data are shared with Benz TDM software
for future measurements.
The Speroni's high-precision spindle with quick-change adapter
allows Heinz Kaiser to switch easily between adapter systems (like
ISO, HSK, VDI and Capto). When an operator goes through 100 tools
per shift, this feature allows for a quick switch, while maintaining
precision and repeatability between adapters. Additionally, because
the system can store 999 adapters or zero points, it's simple to
add a new one at any time and adjust its zero point to any machine
tool on the floor.
The ProVision software allows operators to navigate between
screens without losing any data. This flexibility is convenient
if, for example, a single tool needs to be preset in the midst
of a setup sheet or tool kit.
The click and drag function allows operators to modify existing
icons from the database and store them as customized measuring
icons. This makes current and future tool crib work much easier,
enabling Heinz Kaiser to automate even very complicated tasks.
ProVision's user management feature allows all operators
to have access to the system, but with different authorization
levels. This allows Heinz Kaiser to provide the necessary access
to certain employees, while safeguarding against unauthorized usage.
