FAQs

What is single-pass honing?

Single-pass honing is a manufacturing finishing process that uses one or more progressive tools to finish bore IDs by taking them from the incoming condition to required tolerances.

Why use single-pass honing over traditional honing?

Single-pass honing is a stable, predictable, stable process that is a direct function of tool condition, setup, material, and process variables. Traditional stroke honing is corrective (i.e. chases the size target) and feedback-driven. Therefore, Cpk cannot be applied to the stroke honing process.

Aspect Stroke Honing Single-Pass Honing
Size control Corrective (chases target) Predictive (hits target)
Process loop Closed Open
Output driven by Feedback & intervention Tool + process capability
What is the ideal amount of stock to leave for single-pass honing?

There is no “ideal” amount of stock. Accu-Cut’s diamond tooling can be engineered to remove any amount of stock. When considering stock removal, we want to consider the following:

  • What size tolerance can you comfortably hold incoming to the Accu-Cut process?
  • What is the incoming geometric error?
  • What is the incoming surface texture vs. required surface texture?
  • Are there any processing restrictions (e.g. fixture restrictions beyond the bore, etc.)?

Our engineers use the answers to these questions and more to work with your team to calculate how much stock is best for your application.

Does Accu-Cut keep tool sizes in stock?

Since every application is unique, even among identical parts, we do not have an inventory of tools on our shelves ready to ship. While ID bore sizes and tolerances may be identical, the part and/or incoming conditions may differ. Features such as material type, stock amount, incoming geometry, heat treat process, and more can vary from company to company, even with the same part. This could require different solutions.

What is your lead time?

Our lead time for standard tooling is typically 20 business days. Specialty tools may require additional time. Orders can be expedited for a small fee for quicker delivery.

How much do your turnkey systems cost?

Like our tools, our turnkey systems are unique. Before designing a system, we work closely with your team to determine the best way to support your application requirements. From there, we engineer the tooling solution and build a system around it. System features such as motor type and power, fixture design, automation, post‑process gaging, and more are all tailored to your specific objectives.
