The Anti Lift Jaw System for a 5th Axis Vise & a Comparison between 5th Axis and Lang Workholding

2/18/2020

1 Comment

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.

Use Clamp Confirmation to Safely Load and Unload Your Unilock System

Clamp confirmation for any system, UNILOCK or otherwise, is a sound design criterion when building any workholding system.

It is very common to see clamp/un-clamp confirmation in many automated loading systems as safety interlocking of the CNC machine, robot, robot EOA (end-of-arm) tooling, and workholding can all be integrated to a single master control.

Un-clamp confirmation does have a place in manual situations as well, mostly in large part processing, where cranes are used to lift parts off.

When a clamping system is not directly visible underneath a large part, then this requires an external indicator confirming that the system has successfully un-clamped and that it is safe to lift.

The indicators and sensors can be pneumatic switches which are offered by BIG KAISER or electrical proximity switches as offered by many other companies.

Unilock zero-point automation systems can be implemented at various points of any automation cell.

Blue Photon Labor Saving Chart

2/15/2017

0 Comments

Complex part shapes have time consuming part loads to assure the part is properly nested before machining. Blue Photon makes a hard to load part easy and reduces the number of loads.

Traditional workholding does not usually utilize a machine’s full capabilities because of limited machining access therefore multiple workholding fixtures and process steps are required.

*Labor cost per part was calculated @ $50.00 per hour, based on 21 hours run time per (3) 8 hour shifts/5 day work weeks. 6,240 total hrs. per year

Blue Photon Workholding Labor savings chart

How the blue photon system realized reduce labor cost

With Blue Photon workholding technology, once the part is bonded to the transfer tool it can be loaded into all machines using the same machine mounted workholding fixture system such as Erowa, System 3R etc. The workpiece loads in seconds.

The ability of Blue Photon workholding technology to hold the workpiece on one side providing 5 and in some cases 6 side machining access is unheard of when machining castings and other near-net shape parts.

There is also reduced foot print for this cell and reduced capital investment to create the cell because multiple operations can be done in one workholding.

The concept of using guide pins to load large fixtures has been around for a long time, and it even applies when incorporating Unilock zero-point clamping systems in your fixturing.

The main Unilock clamping knob is very robust, i.e.: very hard, and as such it can cause damage to a Unilock chuck if a fixture is very heavy or large.

Guide pins are set up on the base, and their corresponding holes or notches located on the edge of the fixture pre-position the fixture so, that as it is being lowered, the knobs do not impact the critical location faces of the clamping chuck.

This also has the added benefit of keeping operators in a safe location not having to use their hands & fingers to fine-adjust a slightly out-of-place fixture being lowered.

Everything you wanted to know about the Microconic #Workholding System

10/12/2016

0 Comments

Matt Saccomanno, the inventor of the Microconic Workholding system discussed how it works at IMTS 2016.

Masa Tool has developed the Microconic™ system specifically for holding workpieces from Ø0.15mm to 10mm (Ø0.006" to 0.390") in any machine that has a collet-type chuck.

The system consists of two major components: The Microconic™ cartridge, which fits into your CNC machine spindle replacing the standard 5C, TF20 or TF25 collets, and the Microconic™ collet, which fits in the Microconic™ cartridge.

The Microconic™ system has unsurpassed concentricity: Our manufacturing tolerance is 3µm (.0001") and we guarantee our cartridges to be within 5µm (0.0002") in production use in your machine.

The Microconic™ system works with either draw-type or push-type standard collet systems that are in any machine.

The Over-grip collet capabilities of Masa Microconic™ System, introduces a whole new world of time saving opportunities awaiting. Our Overgrip Collets open up to 4mm (0.157") diameter larger than the clamping diameter.

In case you missed the episode of 5th Axis vises on How Its Made, you can re-watch it right here.

This may be useful in explaining what you do in your job.... even though there's a lot of talk about "carving", "shaping" and "Sculpting"
