Swing Clamps developed to meet your demand for high-speed, precise positioning and/or heavy arm applications in a 7 MPa operating pressure environment. One of the keys to this innovation is the patented spring loaded TuffCam™ design that was developed to improve strength and wear. Using the patented Vektek V-Groove, a stainless steel ball seat, these clamps have reduced static friction for improved clamp breakaway and reduced dynamic friction for improved life. This combination adds up to producing the most accurate and repeatable swing clamp cam assembly.
When do you recommend the use of TuffCam™ 7 MPa Swing Clamps over other Vektek product?
Sometimes there are applications where speed is essential. Sometimes size and weight are critical. Often an available power supply limits pressure available.
What kind of return on my investment can I reasonably expect by converting my manual clamps to TuffCam™ 7 MPa Swing Clamps?
Ask your Vektek sales representative for the Power Workholding Brochure. Time studies and costs are comparable justification.
What makes the cam follower ball seat so special in these units?
The three cams and three cam balls guide the rotation of the plunger and provide greater guide, support and directional stability. The patented cam follower design is unique in the industry and uses solid tungsten carbide balls and stainless steel ball seats. The ball seat design assures that the ball rolls in the cam rather than jamming and scraping resulting in wear on both the cam track and ball. This vastly improves swing repeatability, contacting the same point ±0.25 degrees.
I want to use work supports with TuffCam™ 7 MPa Swing Clamps. Can you give me some tips that will help me get the most from my clamping devices?
Vektek 7 MPa Work Supports and Swing Clamps are made in capacity sets as well as arm-to-support centerline measurement.
It is important to hit my part in the exact place every time in my application. Will your TuffCam™ 7 MPa Swing Clamps meet this requirement?
Standardized repeatability of ±0.25 degrees is "Best-In-Class" Worldwide.
What defines a TuffCam™ 7 MPa Swing Clamp?
TuffCam™ 7 MPa is a single direction tri-cam design swing clamp. These clamps produce the strength and reliability to support faster speeds and larger arms. TuffCam™ 7 MPa delivers notably better accuracy and repeatability over other brands. The clocking feature, dramatically reduces the time it takes to change arms for maintenance, replacement or design set up.
How can I measure the clamp speed?
The maximum speed of a swing clamp is applicable to both clamp and unclamp function, as the momentum on the cam track and cam follower apply to both movements. To approximate the speed of your application:
I want to use the jam nut only to hold my arm in place. Will this work?
It is unlikely that you can use the jam nut to hold arm orientation adequately. We have had customers modify clamps to include flats, pins, serrations or use set screws to hold orientation. These methods may work in specific instances. We still recommend our method of attachment, locknut and cross bolt for a secure, dependable, universal attachment. Other methods may complicate the replacement of clamps when they are damaged by a machine crash or other problems.
Why should I buy your arm rather than have my toolmaker make one?
Our arm is designed to hold orientation when properly installed. It has a relief to keep from over-stressing the locknut. It will probably cost you less than the total cost of making your own. You can rest assured that our arm is made to our specifications and will withstand the forces our clamps generate, when used as recommended.
I need an arm slightly different from those you make. Can I make or modify your arms?
Our first recommendation is to modifying our existing arms if possible. All VektorFlo® arms are able to be machined and welded. You should be able to easily modify any standard arm you purchase. We recommend this because our original design for the cross bolt orientation mechanism is the most secure, dependable and versatile orientation method available. Many customers and competitors have tried to copy it, some with limited success.
If you desire to make your own arm(s), detailed information is available to make your own arms. Please be sure to put in the 0.5 mm step for the locknut and relieve the cut in the arm so that the bolt will squeeze the plunger shaft. If you do not take these two steps, your custom arm may not work satisfactorily.
