Looking for the perfect 5-Axis Self-Centering vise to the test against a leading competitor's vise. We've rigorously evaluated both vises across four critical performance categories to help you make an informed choice for your workholding solution.

Test Categories: 

• Jaw Lift: We examine the vise's ability to securely grip your workpiece, ensuring it won't budge during the most demanding tasks. 
• Jaw Repeatability: How consistent is the vise in holding and releasing your materials? Precision and reliability are key. 
• Jaw Changeover: Time is money in any shop. Find out which vise allows for swift jaw changes, optimizing your workflow! 
• Jaw Recentering: We test the vise's capability to reposition and recenter your workpiece quickly and accurately, saving you valuable time. 

Discover the results and decide which vise is your ideal companion for all your projects.

At Jergens, we're committed to providing top-quality manufacturing solutions, and we believe in transparency. Our goal is to help you make an informed decision when it comes to your tools, and this video is just one example of that commitment.

When it comes to broad capability, there are a few clear machine tool choices that production units and shops consider most – Five-axis, Vertical and Horizontal Machining Centers. The criterion for choosing looks different depending on what seat you sit in – from ownership to management to purchasing and finance – but from the shop floor perspective it’s all about making chips.

Getting the most out of these highly sophisticated machines involves a combination of processes, programming, tooling, workholding and human creativity. Set up between them is very different, too. Workholding on a 5-axis and Vertical Machining Centers is very straight forward – literally – since the spindle points directly to the table.

Setting up a Horizontal Machining Center (HMC) requires quite a bit more thought because the spindle points to . . . well nothing, just into the open space within the machining envelope. So, what’s the call for it?

Over the years, HMCs have evolved from single station to double, with the use of pallet changers, to pool pallets for multiple setups, and now to even include hydraulics within the pallet to load and clamp on the machine. And the evolution continues.

Today’s HMCs have great productivity characteristics including the ability to continue machining in one location while part change can take place in another. Many feature automatic tool changers and automatic pallet changers making them well-suited for uninterrupted, unmanned and continuous machining.

Configurations with multi-axis spindles also permit true five axis machining. And thanks to gravity, the chips naturally fall away from the parts.

​To meet this great potential, requires a review of several workholding issues at the outset.

1.  Angle Plate or Tombstone
First, let’s get back to the open-air orientation. All machining on an HMC starts with a workholding solution. That’s either going to be an angle plate or tombstone (column) that mounts to the HMC indexing table to provide the position and orientation of the workpiece to the spindle. The choice of this fundamental base is dependent upon the answers to remaining things to consider.

2. The Four Basics
As with all machining, all fundamental requirements must be met. Workpieces must be held securely. They must be positioned to allow access to machine all sides (ideally without having to change). Operations have to be repeatable (within tolerance). And the setup has to be designed to be easy for the operator. That includes the ability to clear chips, load, move and other ergonomic factors with the safety of that individual always being priority one.

3. What is your current need?
If you’re gearing up for the next run of parts, it’s best to begin with an SOW (Scope Of Work) including everything from what you’re looking to accomplish now, to opportunities for greater productivity, and how to best support operator skill level.

4. What is down the road?
On the heels of that, savvy engineers are mindful of future needs. Plan for it now and be ready when the demand arises. This past-the-horizon approach saves time for further utilizing technology such as incorporating robotics and other automation.

5. Opportunities for increased productivity
There are two additional productivity boosters available depending on the application. The first is the move from an angle plate to a tooling column for the ability to load a greater number of workpieces for any given setup. This is just a matter of math – a two-sided column essentially doubles that number, three-sided triples, and four-sided quadruples.

For every incremental increase, there is a corresponding decrease in overall setup time (or downtime), and conversely an increase in productivity (or uptime).

​Connections are standard T-slots or grid patterns. The second opportunity is the addition of a quick-change system that allows the entire column to be removed, changed and the next one connected, fully loaded and all in a matter of minutes or even seconds. This quick on and off works when repeatability is high and avoids having to again find zero for every changeover.

Finding the sweet spot for your shop’s productivity is very much a human effort, and a matter of choosing the best combination of man and machine. In the case of high producers like HMCs, the goal continues to be loading and changing parts faster than the machine can make them.

Jack talks about how advancements in 5 Axis CNC machining technology has changed dramatically in the past 20 years. Dynamic Work Offsets and other capabilities have made workholding easier but also given shops even more opportunities to to improve process and reduce cycle time.

The anti-lift jaw system from 5th Axis is available for those customers requiring higher precision and accuracy during secondary operation machining.

The system uses a cleat and angled soft jaw to pull the jaw in and down when torque is applied to the lead screw.

Step 1
Loosen shoulder bolts and remove the standard master jaws from the vise base.

Step 2
Take the shoulder bolts and utilize them to bolt the cleats onto the vise base.  Torque shoulder bolts to 20 ft lbs.  (27.11 Nm)

Step 3
Take anti-lift soft jaw and insert the soft jaw into the cleat.  It helps if you insert the soft jaw at a 45 degree angle.  Ensure that soft jaw seats properly into cleat.

Step 4
Take soft jaw covers and place them on the backside of the jaw.  Tighten bolts to secure covers to the soft jaw.  These covers ensure that no chips on debris enter the anti-lift soft jaw.
