Precision Z-Axis Zero Setter | 50mm CNC Tool Length Presetter

[Product Overview]

The Z-Axis Zero Setter is a must-have tool for any modern CNC machine shop. Relying on the old "paper trick" or touching off directly on the workpiece is not only inaccurate but also risks chipping expensive carbide end mills. Our Z-axis setter provides a safe, spring-loaded measuring surface. By simply bringing the cutting tool down until the dial indicator reads exactly zero, the operator knows the tool tip is precisely 50.00mm above the resting surface. This data is then easily entered into the CNC controller's tool offset registry, guaranteeing perfect part dimensions and preventing catastrophic machine crashes.

[Key Features & Advantages]

• High Precision & Repeatability: The internal mechanism and measuring face are precision-ground to guarantee an accuracy and repeatability of 0.01mm (0.0004").

• Standard 50.00mm Height: The exact 50mm height makes offset calculations incredibly simple for the operator, reducing the chance of mathematical errors during setup.

• Spring-Loaded Protection: The measuring plunge is spring-loaded. If the operator accidentally jogs the tool too far down, the setter will compress, preventing damage to the cutting tool and the machine spindle.

• Magnetic Base Option: Available with a built-in magnetic base, allowing the setter to be mounted sideways on CNC lathes or horizontal milling machines without falling off.

• Large, Clear Dial: Features a large, easy-to-read mechanical dial indicator. (We also offer photoelectric/electronic versions that emit a light and beep upon contact).

[Why Partner with Pingyuan Zhenghao Machinery?]

• Direct Manufacturer Savings: Bypass trading companies and source premium CNC measuring instruments directly from our factory for highly competitive wholesale pricing.

• Strict Calibration: Every Z-axis setter is rigorously tested and calibrated on a master height gauge before packaging to ensure the 50.00mm height is absolute.

• Protective Packaging: Each unit comes in a fitted, shock-absorbing wooden or aluminum case to ensure it arrives at your facility in perfect calibration.

• OEM & Customization: We offer custom laser engraving of your brand logo on the setter body and customized packaging for retail distributors.

Frequently Asked Questions (FAQ) - Selection Guide

Q1: How exactly do I use a 50mm Z-Axis Setter?

A:

1. Place the setter on the machine table or the top of your workpiece.

2. Slowly jog the Z-axis down until the cutting tool touches the setter's plunge pad.

3. Continue jogging in small increments (0.01mm) until the dial indicator needle points exactly to "0".

4. At this point, your tool tip is exactly 50.00mm above the resting surface. Input this offset into your CNC control.

Q2: Do I need the version with the magnetic base?

A:

• If you are only using it on a Vertical Machining Center (VMC), a standard non-magnetic base is usually sufficient as gravity holds it in place.

• If you plan to use it on a CNC Lathe or Horizontal Mill, you must choose the magnetic base version so it can stick to the chuck or sideways fixtures without falling.

Q3: Is this better than using a piece of paper to touch off tools?

A: Absolutely. The "paper trick" relies on the operator's "feel," which varies from person to person, and usually only provides an accuracy of ~0.05mm to 0.1mm. It also risks chipping brittle carbide tools. A Z-axis setter provides a safe, consistent, and highly accurate (0.01mm) measurement every single time.

Q4: Can I use this with very small micro-end mills?

A: Yes, the spring inside the setter is calibrated to be sensitive enough not to break small tools, but firm enough to provide an accurate reading. However, for extremely fragile micro-tools (under 1mm), an optical/laser tool presetter might be recommended.
