JPT Way Integration

What are Best Practices?

The casual observer may interpret the term "Best Practices" and consider that such a concept is subjectively slanted with many personal points of view. Within the context of the JPT White Paper and Case Study Offerings are experiences drawn from successes as well as failures since our founding in 1971.

JPT "Patented" Generating Tools (Motion) for Machining Differential Carriers

Protected Under United States Patent Numbers: 5,086,676 & 5,211,088

Plus Other U.S. and Foreign Patents Pending

Since 1983, JPT has designed and manufactured Diff-Carrier tooling evolving into our "Best Practices" or “The JPT Way”.

Our specialty application experience covers Many, Many different types of parts and associated materials that require exacting tolerances.

Differential Carriers are a PRIME FOCUS of JPT.

There are many ways to machine Differential Carriers.

  • Eccentric Spindles or Holders.
  • Circular Interpolation.
  • Padded "Style" Tooling.

During this time JPT has established a great library of application knowledge ........... Including (5) Diff-Carrier part prints in the past three years alone.

As a result of this, JPT has developed the Patented "JPT Differential Carrier Generating (Motion) Tool" that provides extremely high quality workpieces and tool life.

This success is due to VERY SPECIFIC JPT design and manufacture focus on;

  • Fixture design.
  • Insert material, geometry and tolerancing.
  • Recommended speeds and feeds.
  • Workpiece material and process.
  • Machine Tool Specifications.
  • Part "In" condition.....prior operations.
  • Locate and clamping points / method.
  • Tool Setting Offset Gaging.
  • Run-off requirements.

In addition to the above, JPT is frequently involved in the process and fixture concepts as well as the machine tool application and maintenance. Our involvement in all of the mentioned elements produces very successful applications.

So successful are these that a number of elements have United States and International Patents (and Patents Pending)....including the "JPT Differential Carrier Generating (Motion) Tooling System" utilized by Machine Tool Builders for converting new or existing equipment into Diff-Carrier machining cells.

When we are asked to "quote a tool" along with "back-up" inserts.........without the aforementioned involvement.....the outcome is generally poor and all involved have generally been displeased. We are certain that this is due to the "Manufacturing Marketplace" viewing this type of tooling as a "COMMODITY" (such as a standard catalog toolholder or insert) and fairly often not understanding the discipline required and the complexities involved.

Subsequently, JPT's increased involvement in all areas of Diff-Carrier manufacturing has grown out of necessity as needed by our customers.
