Krasnic Electric Tapping Machine and Its Operating Modes

Used in workshops for fast, practical and precise threading of large and small workpieces, the Krasnic Electric Tapping Machine makes the operator’s job considerably easier thanks to its high torque and articulated arm mechanism.

Watch Temak Teknik’s video below explaining the machine’s technical specifications and operating modes:

Key Technical Specifications

• Tapping Capacity: Taps threads over a wide range from Metric 6 to Metric 30 (M6 – M30) [00:00].
• Power Requirement: Runs on a standard 220 V mains supply [00:09].
• Spindle Speed: Reaches a maximum speed of 200 revolutions per minute (RPM) [00:09]. Forward and reverse speeds can be set independently (e.g. 150 RPM in, 200 RPM out) [01:08].
• Holding System: Uses torque-limiting adaptors with a 31 mm shank diameter [01:30].
• Display & Interface: Features an easy-to-use digital touchscreen control panel with a Turkish-language interface [00:24].

Operating Modes of the Machine

1. Manual Mode

   • After locating the tap in the hole, the operator taps the thread by holding down the button on the arm [02:05].
   • Once tapping is complete, the operator presses the reverse button to withdraw the tap from the hole [02:21].

2. Automatic Mode

   • The target hole depth (e.g. 15 mm) is set on the display [00:59].
   • With a single press of the Start button, the machine taps to the preset depth and, on reaching it, automatically reverses and withdraws from the hole [02:46].

3. Peck Tapping Mode

   • Used especially for deep holes or materials with a high risk of chip packing [00:30].
   • The peck depth and retract distance are set on the display (e.g. advance 5 mm, retract 2 mm) [03:23].
   • The machine advances step by step, breaking the chips, and withdraws automatically once the operation is complete [04:20].
