J & L Diamond Dressers

Braemar USA J & L Diamond Dressers are precision single-point diamond tools designed for Jones & Lamson thread-grinding machines. Their sharp, accurately positioned diamond points dress conventional abrasive wheels to the precise profiles required for producing consistent thread forms.

Thread grinding demands exceptional wheel accuracy because small variations can affect the finished thread angle, pitch diameter, root radius, and surface finish. Therefore, Braemar USA manufactures each J & L diamond dresser with a rigid steel shank and carefully selected diamond for clean dressing action and repeatable results.

Diamond Dressers for Jones & Lamson Thread Grinders

J & L Diamond Dressers restore the grinding wheel’s required shape while exposing fresh abrasive cutting points. During dressing, the diamond removes loaded bond material and dull abrasive grains from the wheel surface. As a result, the wheel cuts more efficiently and maintains a more accurate thread profile.

The rigid 0.250-inch shank securely supports the diamond under demanding dressing conditions. In addition, controlled diamond exposure helps minimize vibration, chatter, and premature point wear.

Benefits of J & L Diamond Dressers

Precision Thread-Grinding Applications

Braemar USA J & L Diamond Dressers are well suited for:

Precision thread grinding
Grinding-wheel form dressing
Thread-angle generation
Root-radius and crest-form dressing
Straight and tapered wheel-face dressing
Grinding-wheel truing and conditioning
Tool-room wheel maintenance
Automotive and aerospace component production
Precision fastener and threaded-part manufacturing
High-volume production grinding

These diamond dressing tools are commonly used with conventional aluminum-oxide and silicon-carbide grinding wheels. However, proper selection depends on the abrasive, bond, grit size, wheel diameter, thread form, and dressing conditions.

Standard J & L Diamond Dresser Specifications

Braemar USA offers J & L Diamond Dressers in the standard Jones & Lamson-style configuration:

Shank diameter: 0.250 inch
Overall length: 1.000 inch
Diamond size: 0.07–0.08 carat
Diamond grades: Standard and Select

The Select-grade option provides a higher-quality diamond for applications requiring improved point integrity, consistent form retention, and longer service life.

Custom Thread-Grinding Diamond Tools

Thread forms vary by application. For this reason, Braemar USA can manufacture J & L Diamond Dressers with custom included angles, point radii, diamond grades, and shank configurations. These options allow the dressing tool to match the Jones & Lamson machine, grinding wheel, and finished thread requirements.

When requesting a custom J & L dresser, specify the machine model, shank dimensions, included angle, point radius, wheel specification, and required thread form.
