Mechanism Details

Engineered for Unfailing Performance

NextasTech Zero-Point modules are the foundation of modern manufacturing efficiency. Each module is crafted from high-grade, hardened alloy steel for maximum rigidity and service life. The ingenious internal mechanism uses pneumatic pressure (typically 6 bar) to overcome powerful springs for unlocking. When the air is removed, these springs instantly and forcefully pull in and lock the clamping stud, creating a positive, vibration-proof connection that is completely secure.

Selection & Integration Guide

How to specify a zero-point system for your machine

  1. Define your changeover goal: pallet swaps, fixture swaps, or both. This sets the receiver count and pallet strategy.
  2. Select receiver size: based on fixture weight, cutting load, and available footprint (85 / 120 / 160 / 195 mm options).
  3. Choose pull studs: standard vs. compact vs. anti-rotation, depending on clearance and datum requirements.
  4. Plan the sub-plate: optimize receiver spacing for tool access, chip flow, and coolant drainage.
  5. Decide air routing: bottom inlet for clean through-table plumbing; side inlet when through-table routing isn’t possible.
  6. Automation readiness: add clamp/unclamp confirmation sensors for APC/robot cells and safe PLC sequencing.

Typical retrofit paths

Zero-point systems pay off fastest when you standardize one interface across multiple setups. Here are the most common upgrade routes we support.

3-axis CNC → quick-change fixtures

Mount a receiver pattern on a sub-plate and add pull studs to your vises/fixtures. Great for mixed-batch work and short runs.

5-axis CNC → compact, high-access fixturing

Use dense receiver layouts and low-profile fixtures to maximize tool access and reduce re-indicating between operations.

Automation cell → pallet pool / APC / robot

Add clamp confirmation signals and consistent pallets to enable safe unattended changeovers and higher spindle uptime.

Receiver sizing & layout quick guide

These guidelines help early-stage planning for a quick-change pallet / fixture interface. Final selection depends on cutting loads, moments, and machine constraints — share your setup and we’ll propose a layout.

Frequently Asked Questions

How does the 'fail-safe' mechanical locking work?
Our zero-point system uses powerful pre-loaded springs as the primary locking mechanism. Clamping is mechanical and constant. Pneumatic pressure (typically 6 bar) is used to unlock. If air pressure is lost, your workpiece remains secured — ideal for unattended machining and automation.
What is the difference between the 'Bottom Inlet' and 'Side Inlet' solutions?
Bottom inlet routes air through the machine table or sub-plate for a clean, protected installation. Side inlet is a flexible option when through-table routing isn’t possible — air lines connect from the side of the module.
Can these modules be used for applications other than CNC machining?
Yes. We commonly see zero-point receivers used on CMM inspection stations, welding fixtures, assembly lines, and EDM processes — anywhere that repeatable positioning and fast changeover improve throughput.
What maintenance is required for the zero-point modules?
Keep the seating area clean, inspect periodically, and apply light lubrication as specified in the manual. In chip- and coolant-heavy environments, routine wipe-down and occasional leak checks help keep unlocking and seating consistent over time.
How do I integrate the system for automated position monitoring?
Automation-ready modules can be configured with sensor ports for proximity sensors that provide clamp/unclamp confirmation. This feedback can be wired to a PLC or robot controller to validate system status before an automated cycle starts.
How do I choose the right module size (85 / 120 / 160 / 195 mm)?
Start with pallet/fixture footprint, part and fixture weight, and cutting loads. Smaller receivers fit compact 5-axis fixtures and dense layouts; larger diameters provide higher load capacity and stiffness for heavier pallets, tombstones, and roughing. Share your table size and changeover goal and we can recommend a safe configuration.
Which pull stud should I use, and how important is stud quality?
The pull stud is the precision interface between your fixture and the receiver, so it impacts repeatability and wear. Choose the style based on clearance, fixture thickness, and whether you need anti-rotation. Precision-ground studs with consistent hardness and surface finish help keep repeatability stable over many cycles.
What air quality / filtration is recommended for stable long-term operation?
Use clean, dry air at the specified unlocking pressure (typically 6 bar). A filter-regulator or FRL unit helps protect seals and keeps unlocking consistent. Stable air quality is especially important for automated cells and repeatable unclamp timing.
Can I retrofit an existing fixture or vise to a zero-point system?
Yes. Many customers retrofit vises, chucks, and custom fixtures by adding pull studs to an adapter plate or the fixture base. The key is maintaining a stable datum scheme (flatness and bolt pattern) and providing chip/coolant clearance so the system seats cleanly every time. Send us your fixture drawing and we’ll propose a practical retrofit approach.
