DIGITAL MICROMETER HEAD 350 series

Upgrade Machine Precision with the Digital Micrometer Head 350 Series

Integrating precise linear movement into machinery demands rugged, high-accuracy hardware. Standard measuring heads often fail when exposed to coolant, oil, or cutting fluids. The Digital Micrometer Head 350 Series solves this problem completely. This IP65-rated drive unit delivers instant electronic readouts in harsh workshop environments.

What is the Digital Micrometer Head?

The Digital Micrometer Head 350 Series is a coolant-proof electronic head designed for direct machine integration. Engineers mount this specialized component onto translation stages, custom jigs, and automated fixtures.

Its advanced rotary sensor tracks spindle travel accurately without losing origin position. The clear LCD screen displays live travel distance down to 0.001 mm resolution, even when exposed to splashing fluids.

Key Features That Drive Performance

  • IP65 Water and Dust Protection: Fights heavy cutting coolant sprays and shop debris.

  • Large LCD Display: Eliminates reading mistakes and speeds up manual adjustments.

  • SPC Data Output Port: Exports live measurement values directly to external SPC network devices.

  • Non-Rotating Spindle Options: Prevents surface distortion on delicate parts during contact feed.

Core Industrial Applications

Automation engineers specify the 350 Series head across demanding manufacturing fields:

  1. Machining Fixtures: Provide adjustable reference stops on CNC workholding tools.

  2. Precision Stages: Control X-Y optical positioning inside dirty shop environments.

  3. Automated Gaging Units: Send real-time positional data to central quality databases.

Why Quality Teams Prefer It

  1. Protects Tool Longevity: IP65 sealing prevents liquid penetration and internal corrosion.

  2. Reduces Human Error: Crisp digital numbers eliminate traditional Vernier parallax mistakes.

  3. Streamlines Quality Audits: Direct SPC output automates manufacturing data collection routines.

How to Choose the Right Model

First, evaluate stem mounting needs like smooth or threaded stems with locknuts. Next, pick between flat or spherical spindle faces based on your contact workpiece shape. Finally, select models with ratchet thimbles for uniform contact force.

Simple Maintenance Practices

Wipe the spindle clean with a lint-free cloth daily. Check the battery seal during replacement to preserve water resistance. Store extra units in protective cases.

Upgrade your machinery with the Digital Micrometer Head 350 Series today to maximize positioning accuracy and stop fluid damage.
