Description

The Paprsky Thread Scale Centre Gauge – 55° serves as a highly precise stainless-steel instrument engineered specifically for lathe threading applications. It is utilized to verify and establish the exact angle of single-point screw-cutting tools, square the threading cutter perpendicularly against the workpiece, and supply reference graduations for standard thread pitches. Tailored for 55° Whitworth thread profiles, this gauge facilitates precise tool grinding, exact positioning, and accurate thread evaluation. Its streamlined, portable design makes it a highly effective asset for maintenance crews, machinists, and educational workshops requiring dependable thread-cutting setups.

Key Features 

  • 55° Whitworth Thread Reference: Engineered specifically to establish and verify tools meant for standard 55-degree thread profiles. 
  • Thread-Pitch Scale: Features engraved reference graduations for 14, 20, 24, and 32 threads per inch (TPI). 
  • Single-Point Tool Setup: Facilitates the accurate establishment and verification of angles on single-point threading cutters. 
  • Threading-Tool Alignment: Aids in squaring the cutter exactly perpendicularly to the workpiece prior to initiating the threading pass. 
  • Tool-Grinding Support: Acts as a reliable master template when shaping and grinding cutter bits to the necessary thread angle. 

Usage Instructions 

  1. Verify that your target thread profile dictates a standard 55-degree Whitworth angle. 
  2. Choose the appropriate scale on the gauge that matches the necessary thread pitch for your operation. 
  3. Apply the tool's 55° cutout to evaluate or shape the single-point cutter to the exacting angle required. 
  4. Set the gauge firmly against the material and square the threading tool perfectly perpendicular to the axis of the workpiece. 
  5. Utilize the engraved thread scales to verify that you are set up for the designated pitch. 
  6. Double-check your cutter alignment and tool angle prior to engaging the lathe. 

Applications 

  • Lathe Operations: Preparing equipment for precise screw-cutting tasks and turning operations. 
  • Machining Workshops: Verifying threading tool alignments and angles throughout daily machining processes. 
  • Aerospace and Automotive: Aiding in the setup of cutting tools and the verification of thread profiles on rigorous machine components. 
  • Tool Grinding: Serving as an accurate reference guide while fabricating and shaping single-point cutters. 
  • Technical Training: Educating apprentices on pitch identification, correct tool positioning, and interpreting thread angles. 
  • General Maintenance: Assisting with routine tool setup and thread evaluations during industrial facility upkeep. 

Paprsky supplies functional precision instruments crafted to aid in uniform setups and accurate dimensional assessments across maintenance, fabrication, and machining workspaces. This Thread Scale Centre Gauge – 55° delivers a highly portable, stainless-steel template for identifying thread pitches, confirming angles, aligning equipment, and grinding Whitworth threading tools.
