Positioning Sleeve 428145 for Powermax125 Plasma Cutting Torch Consumables Kit: Duramax Hyamp 180° machine torch mounting sleeve

1. Product Identification & Overview

• Hypertherm Part Number: 428145

• Product Name: Positioning Sleeve, Duramax Hyamp 180° Machine Torch

• Common Name: Mounting Sleeve, Torch Mount, Tool Holder.

• Primary Function: This is a precision mounting accessory for the Duramax Hyamp 180° machine torch. Its sole purpose is to provide a secure, accurate, and repeatable method of attaching the torch to a CNC (Computer Numerical Control) plasma cutting machine's Z-axis.

2. Key Features & Design Benefits

• Precision Alignment: Ensures the torch is mounted perfectly perpendicular (at a 90-degree angle) to the cutting surface. This is critical for achieving square, non-beveled cuts.

• Repeatable Height: Provides a fixed, known datum point for the CNC machine's height control system to reference. Once the initial tool length (torch tip-to-work distance) is set in the CNC software, the sleeve ensures it can be repeated consistently.

• Secure Clamping: Designed to be firmly clamped by the torch holder on the CNC machine's Z-axis, preventing any movement or vibration during cutting.

• Durability: Made from a high-strength material (typically a engineered plastic or composite) to withstand the harsh environment of a plasma cutting table, including heat, sparks, and metal dust.

• Simplified Torch Changes: Allows for quick and easy removal and re-installation of the torch body without losing the critical alignment setting.

3. Compatible Systems

• Torch Body: This sleeve is designed specifically for the Duramax Hyamp 180° Machine Torch for Powermax125.

• The main torch body part number for this torch is 428147.

• Power Supply: Hypertherm Powermax125 and Powermax125 G3.

• Application: Exclusively for mechanized/CNC plasma cutting systems.

4. Relationship to Consumables

• Not a Consumable: It is crucial to understand that the Positioning Sleeve (428145) is not a wear item or consumable in the traditional sense like a nozzle or electrode.

• Fixture, Not a Wear Part: It is a mounting fixture. It does not directly interact with the plasma arc and has no prescribed service life. It is only replaced if it becomes physically damaged (e.g., cracked, broken, or warped by excessive heat).

• Part of a "Kit": It may be referred to as part of a "kit" because it is an essential component for setting up a complete, functional machine torch system alongside the torch body, leads, and consumables.

5. How It Works in Practice

1. Installation: The torch body (428147) is inserted into the bore of the Positioning Sleeve (428145).

2. Mounting: The entire assembly (sleeve with torch) is then clamped into the tool holder on the CNC machine's Z-axis.

3. Tool Length Offset Setup: The machine operator jogs the Z-axis down until the end of the positioning sleeve touches a known surface (e.g., the surface of the metal plate). This position is set as the "zero" or "touch-off" point in the CNC control.

4. Cutting: During operation, the CNC control uses this stored zero point to calculate the exact height to raise the torch for piercing and then lower it to the correct cutting height (standoff), ensuring perfect repeatability.

6. When is this Part Needed?

You would typically purchase this part in two scenarios:

1. New CNC System Integration: When installing a new Duramax Hyamp 180° torch onto a CNC table for the first time.

2. Replacement of a Damaged Sleeve: If the original sleeve is cracked, broken, or has become loose, compromising the rigidity and accuracy of the torch mount.
