Features

Constructed with aerospace-grade aluminum, the RockLock™ base embodies the perfect blend of versatility and robust durability. Its industry standard 96mm pull stud spacing ensures a seamless fit into your machining setup, reducing unnecessary bulk while maximizing workspace efficiency. One of the standout features of this system is its adaptability. Inside the RockLock™ base, you’ll find hardened steel internals that are engineered for precision and longevity. The RL96A-3613S3 is a multi-position RockLock™ plate built for maximum efficiency on small to medium vertical mills. The nested RockLock™ 96mm pattern allows for the operator to utilize one single large vise or two smaller vises. 100mm T-slot spacing for 3 axis mills.

Time = Money

Reduce setup times by 80-95%.¹

Swap Vises & Fixtures Quickly.

A standard mounting pattern allows for easy movement of vises, fixtures, and tooling from machine to machine no setup time.

High Accuracy

Patented free float design ensures equal force on all 4 pull studs guaranteeing repeatability of less than .0003″ (8 microns)

Standardize Your Setups.

Stop building custom adapters and subplates for every new job that comes into the shop. Job changeover becomes simple and repeatable with the RockLock™ system, saving you time and money.

Simplify Programming.

Established work offsets help speed up programming time when adjusting for different jobs and top tooling.

Easy Integration.

Pull studs are easily integrated into existing fixtures and subplates. Standard 52mm and 96mm spacing allow for compatability with competitive systems.

Built To Last

All RockLock™ baseplates feature hardened steel rings and locking mechanisms. This ensures repeatability and wear resistance for the life of the product.

Smooth Operation

All units are operated via a simple allen wrench. The leadscrew only needs to be operated from one side, but has access from both sides; no reaching around your vise or parts.

FAQ

How do I know what RockLock™ plate fits my machine?

We’ve designed RockLock™ plates in a variety of styles to perfectly fit your CNC machine. Whether you need low-profile plates, multi-position plates, risers, pyramids, tombstones, or right-angle adapters, RockLock™ is available in nearly any configuration you can imagine. Use our 3D machine configuration tool to find the best RockLock™ setup for your machine.

What is the pull-down force / clamping force of the RockLock™ system?

You should expect a pull-down force of 2000lb preload at each pull stud. There are four pull studs in every RockLock™ quick-change system.

How does the RockLock™ system work?

When the leadscrew is tightened using an Allen wrench, the clamping pull studs are pulled down by two free float cam pieces. The precision OD on the pull stud is located on the precision ID of the RockLock™ plate and the cam pieces locks the pull stud into position.

Is the RockLock™ system compatible with other systems on the market?

Yes, the RockLock™ quick-change system uses the industry standard 52mm or 96mm pull stud spacing. This allows interchangeability between competitive systems. Each manufacturer has a different patent on the cam system and how it interacts with the pull stud. This means that the base plate and the pull stud must be from the same manufacturer, but the vises and top tooling are completely interchangeable.

How do I align my RockLock™ plate with my CNC machine?

Ensure your RockLock™ base (RL96 or RL52) is securely mounted to your machine table or tombstone.
Engage the pull studs into the RockLock™ system by actuating the clamping mechanism (typically via a torque wrench).
Utilize a dial indicator or probe to touch off on the top and sides of the master pallet. Use the clearance holes to loosen or tight the masterpallet and continue to adjust until the master pallet is in alignment with your machine.

What is the max weight I can place on a RockLock™ plate?

We do not put a specific weight limit on the system. Here are so considerations when looking at the weight of your workpiece:
Clamping Force & Holding Torque – Systems like RockLock™ use pull studs and clamping mechanisms rated for specific loads. The 96mm system, for example, is designed to handle significant forces and is suitable for heavy-duty applications.
Workpiece & Fixture Weight – While the RockLock™ system can handle hundreds of pounds, the machine table’s load capacity often becomes the limiting factor.
Dynamic vs. Static Loads – While a system may hold a heavy static load, high-speed machining and cutting forces introduce dynamic loads that can impact stability.
Machine Table Limitations – The weight of the fixture + workpiece should not exceed the machine’s table weight rating.

Can I build my own subplates or adapters for the RockLock™ system?

Yes, the RockLock™ system was built to be open source and compatible with existing subplates and fixturing. We know fixturing and tooling is expensive and we designed the system to make existing subplates and fixtures adaptable to the RockLock™ system. We will provide you with the drawings to easily prep your fixtures to work with the RockLock™ system.
