Kurt MiniLock Clamp

The Kurt MiniLock™ is a small, screw down clamp that operates

much like a precision vise. Designed to hold small parts for machining, the MiniLock provides a

low cost, easy-to-use option for rigidly clamping components on machine tables, pallets andhttp://www.kurtworkholding.com/workholding/minilock.php

trunion fixtures.

Operation of the MiniLock is similar to the original Kurt Anglock® vise design. When a

quarter turn is applied to the MiniLock screw, the split clamp jaw of the MiniLock is forced both

laterally and down, precisely clamping the part while preventing the part from lifting.

The Kurt MiniLock is very versatile. It can be used in single holding, double holding or

multiples of both single and double holding applications. By using stationary blocks or pins, two

parts can be clamped using a single MiniLock. Its low profile allows for machining complete top

surfaces of parts without having to re-clamp the part. Also, steps can be machined into the

MiniLock jaw for machining operations that require parts to be raised above the pallet or the

machine table.

MiniLocks are ideal for use in dedicated fixture setups and for palletizing small parts to be

loaded into receivers on machine tables. Through the use of a variety of locating blocks,

workstops and MiniLocks, several similar components or a part family can be located and

clamped on a single pallet.

“The MiniLock is another innovative clamping option from Kurt that fills a need where

small parts need to be machined in large quantities,” reports Steve Kane, global sales and

marketing manager for Kurt Industrial Products. “Without the size, weight or cost, MiniLocks

operate like full-fledged vises. They work well on most machining centers. They are ideal for

hard fixturing using multiple pallets so while one pallet of parts is being machined, the operator

can unload/load a second pallet.”

Kurt DoubleLock HDL Series Vises

We have had some comments from customers that the metric jaw plate bolts are causing some confusion. This was originally done to hold down manufacturing costs and to provide a “Global” product.

In response to this issue Kurt is immediately adding all English versions of the HDLM4L, HDHLM4J, HDLM6J and HDHLM6J. For those versions we will drop the “M” in the part number. Until this can be accomplished internally, we will question all orders coming in and list the bodies and jaw kits separately to get the English version. Pricing will stay the same.

We sincerely apologize for any confusion this has caused.

New Kurt® HDM690 Vise Has Full 9-Inch Jaw Opening – Repeatable 0.0007 Inch Clamping Accuracy

Kurt’s new HDM690 vise is the ideal vise for precision clamping very large parts for tool and die and production CNC applications.


Featuring a full 9-inch jaw opening, this new vise clamps larger parts with repeatable 0.001 inch accuracy and minimal stationary jaw deflection. Designed with a rigid stationary jaw, the vise features top-down bolting and a tall body design to reduce deflection.

High precision roller bearings and a specially hardened vise screw mechanism enhances precision clamping and smooth operation. The design distributes up to 6,000 lbs of clamping force evenly and precisely across the full jaw surface. Kurt’s AngLock® spherical segment in the moveable jaw (originated and patented by Kurt) further reduces jaw lift. The pull-type body design stabilizes stress in the vise body resulting in more accurate clamping of all types of parts.

Adding to overall vise rigidity while absorbing machining vibration, Kurt HDM 690 vises have 80,000-PSI ductile iron bodies with precision machined components. Together, these features combine for many years of trouble-free, precise clamping backed by Kurt’s exclusive Lifetime Ironclad Warranty.

Setup features of this new vise include: Stationary jaw bolts down from top. No need to remove from table to disassemble vise. Bolting the stationary from the top reduces the stress in the body and will stay flatter after assembly. Narrower vise body width allows for more vises in the work envelope. Bolts and locates directly on standard grid plates: 40mm, 50mm and 2 inch. Has quick-change movable jaw. This HD movable jaw vise platform allows for quick-change jaw carvability to hold flat odd-shaped parts.

Additional features include: uses sine keys for alignment, GroveLock® jaw and workstop included, adaptable to double-actuating hydraulic operation for use with robotics (with custom parts), available with optional grid plate and swivel base.

“The new Kurt HDM690 vise fills a need between Kurt’s D688 and 3600 vise models,” reports Steve Kane, global sales and marketing manager for Kurt Industrial Products. “It gives machine operators another Kurt option to improve productivity and machining quality at a modest investment.”

Kurt Workholding Celebrates 50th Anniversary –

Grew From A Single Anglock® Vise Model

To Over 500 Different Workholding Product Choices

Minneapolis, Minnesota: 2010 marks the 50th anniversary of the Kurt AngLock Vise and Kurt Industrial Products. It all began with one vise model – the D60 AngLock and it quickly became the vise of choice by machinists everywhere because of its unique patented design.

“The Kurt AngLock vise was designed at the same time computer numerical controlled machines became the new manufacturing technology of the day,” reported William Kuban, CEO and son of the founder of Kurt. “It was truly a manufacturing revolution. Everything changed because CNC machines were smarter, faster and more precise. The AngLock vise provided the workholding accuracy and repeatability for these automated, high speed systems.”

From the start, Kurt was the industry leader and through the years developed many exclusive vise and workholding designs that defined that industry category. For its 50th anniversary, Kurt displays a special logo labeled the Kurt “360° Product Advantage”. The logo represents today’s hundreds of Kurt workholding product options. These include multiple station CNC vises, 5-axis vises, rotary table workholding, MultiChuck MMY static milling chucks, DockLock zero point clamping systems, a full line of tombstones for achieving maximum high density workholding and accessories to complement every workholding setup. Kurt is the exclusive worldwide distributor of NEMI vacuum workholding. Kurt also provides a full line of automated and manual gaging systems, SPC software and is a Fanuc integrator for automation.

During its 50 very successful years as the workholding leader, Kurt set new standards for quality, durability and precision. In 2002, it achieved the milestone of 500,000 vises sold with many of its first production models still in everyday, shop use. “We see those 40 and 50 year old Kurt vises on machines in shops all the time,” reports Mr. Kuban. “You can’t miss them because the bases are painted gray.” (Today’s Kurt vise bases have a blue finish so it’s easy to differentiate the new from the old).

Precision machined out of 80,000 lb PSI ductile iron, Kurt vises and all of the workholding products it manufactures are so durable and reliable that they are backed by a Lifetime Ironclad Warrantee. Numerous awards have been won by Kurt through its 50 years including international recognition for best vise and workholding brand.

“These achievements are made possible by our outstanding employee commitment through the years” reports Mr. Kuban. “Their continual dedication to precision and quality has moved us to where we are today and toward an even more promising future.”

Kurt’s 50-year milestone is underscored by a new facility Kurt moved into 24 months ago. The facilities include an impressive Automated Production system designed for eventual lights out manufacturing of many Kurt vise product lines.

“What’s most impressive about this system is that it incorporates a wide variety of Kurt workholding products,” reports Mr. Kuban. ”We utilize standard Kurt workholding, custom engineered workholding and towers, the DockLock system and automated custom engineered systems to put this cell together. We wanted to make this a showpiece of all Kurt’s technical abilities for present and prospective customers to see.”

Looking forward to the next 50 years, Kurt believes it has a very bright future. “Machinists, process planners and engineers, through continuous improvement programs, are continually upgrading workholding applications,” stated Mr. Kuban. “That means a growing need for new, innovative workholding designs. Kurt will continue to be the driving force for these innovative workholding designs.”
