History Of Vises Vises date back to the beginning of the Industrial Revolution. Their refinement parallels the advancements in machine tool technology, which was greatly accelerated in the 1960’s with the advent of computer numerical control (CNC) machines. |

 Are you Machining with 5 Axis?
Why not use a Kurt VB 5 Axis Schenke Clamping System?
Machine on 5 sides with one single clamping operation using the Kurt VB 5AX100 Schenke Clamping System. This patented clamping system provides up to 40 kN clamping force for obstruction-free machining on five sides. It allows high speed, continuous 5-axis cutting motion of sculptured surfaces, pockets and other 3-dimensional features in a single clamping setup. (read more) |

Using and maintaining your vise properly will insure long reliable service from your vise. Here are some things to consider to get the most out of your workholding.
By Steve Tschida, Engineering Manager, Kurt Manufacturing
| Clamping |
 When clamping a part in a vise, keep it down in the jaws as far as possible. The higher up in the jaws you hold a part, the more jaw deflection you will experience. |
 |
 Also, keeping your parts centered on the stationary jaw face is always good practice. This will apply uniform force across the face of the stationary jaw. Keeping the part to one side of the stationary jaw face will cock the jaw, creating misalignment. |
 |
 If you wish to clamp two smaller parts at the same time, place one on each side. |
 Never try to clamp more than two parts at the same time without special jaws to account for any part size variation. |
| Tightening |
 It is good practice to become familiar with your vise’s clamping forces. Too much clamping force could damage parts with thin wall sections. Also remember that repeatable clamping pressures will help you achieve better accuracy. When tightening a vise, never use a cheater bar or hammer to strike the handle. |
| This excessive pressure can cause damage to the vise’s internal parts. The handle of your vise is properly designed to allow for adequate clamping pressure. |
| Maintenance |
 To assure continuous service of your vise, it is important to regularly clean and maintain it. |
 Precautions should be taken during the machining cycle to never let chips pack inside the vise. |
This could cause damage to seals that protect from chip / coolant contamination. Your vise should be taken apart periodically and cleaned. Upon re-assembly, look at the seals for damage and replace if necessary. Also look at the thrust bearings for damage and replace if necessary. Make sure the threads in the nut are free from chips. Upon assembly, lightly oil the inside of the nut and install the screw. Grease the thrust bearing with a good wheel bearing grease and install. Lightly oil the way surface top and bottom so the movable jaw and nut ride freely. When finished assembling, lightly oil all machined surfaces to prevent rust.
Following the tips on clamping, tightening and maintenance will ensure that your vise performs as it was intended. |

How to improve part setup time from 5 minutes to less than a minute. Here's one 'Medical Miracle' which accomplished even more.
 Five Kurt HDL double station vises mounted side by side on a new Bridgeport VMC 1000 Xp3 vertical machining center (VMC) gave Vincent Precision Machining setup time improvement of under a minute per part compared to over five minutes per part for its 420 stainless steel medical components. The time saving was huge because five new vises are used in the new setup compared to just two in the earlier setup. (Read More)

 Kurt Self-Centering Vises
Kurt has two Self-Centering vises, a four inch jaw width (SCD430) and a six inch jaw width (SCD640). Jaw opening on the four inch model is 6.25", and 8" on the six inch. Centering accuracy from minimum to maximum opening is 0.0006" with 0.0002" repeatability. Both movable jaws are Anglock design with zero lift. A unique feature is an adjustment that allows the centerline of the jaws to be set. This is especially important when mounting several vises on one machine and all centerlines must match.
Additional features include:
Adjustable Gibs in each moveable jaw for maximum accuracy.

Is Zero-Point Workholding For You?
 The VB DockLock system is a patented, zero-point workholding system for increasing productivity and reducing setup and changeover. The VB DockLock system integrates with new or existing workholding devices such as Kurt vises and fixtures, and provides fast, ultra accurate setup on machining centers. Time consuming setup, alignment and bolt down tasks are eliminated.
The system consists of a patented hydraulic actuated locking cylinder device that positions and locks the vise or fixture onto the machine worktable. It allows the user to locate or remove the workholding from a machine, or move it offline or to another machine and/or back again in just seconds with zero-point positioning accuracy every time.
