 December 2004 - Vise selection and their characteristics (Part One of a Series)
The key factor in choosing a vise for a knee mill is the vise opening and whether or not a swivel base is needed. Also for consideration is the addition of a workstop on the machine table or affixed to the rear of the stationary vise jaw. If parallels are included, the no-lift moveable jaw will keep these parallels in contact with the part for correct alignment in the mill. (Click here to view more selection details) |

Reduce downtime and set up time.
The Clak parallels simply snap in and out of the master jaw, eliminates external clamps and locks thanks to the internal locking system.
The Clak system also increases the accuracy of finished parts and reduces scrap. Sets come with complete with jaw plates, six pair of parallels and storage box. Kits come complete with six pair of parallels and storage box. All components are hardened and precision ground.

Pinning jaw plates to accurately locate jaw plates to the face of movable or stationary jaw blocks are a common practice. Two dowel pins can be used (one diamond and one round) with drilled and bored holes both in the face of the movables and stationary jaws. Of course, drilled and bored holes should be in the jaw plates to match to the stationary and movable jaw block. |

Kurt AngLock vises are designed for maximum efficiency. Be sure your work piece is clamped correctly in the bed of the vises as low as possible. Use just hand tight forces with handle supplied so as to not damage the workpiece of vise. |

DoubleLock Maintenance
When performing maintenance of your Kurt DoubleLock vises, be sure the nut an screw assembly is properly timed when you assemble so the vise will work properly. Check with Mike Chester at Kurt Manufacturing if you have misplaced your timing instructions.

Diamond Coated Hard Jaws
There comes a time in the experience of every machinist when the job at hand requires a different approach. Before you exceed the recommended maximum torque and risk damaging your Kurt vise or distort the part, consider the following;
- On all single station vises, excessive clamping torque results in excessive deflection of the stationary jaw.
- Lowering the clamping screw torque could cause the part to move
Solution: There are two products on the market to increase friction between the vise and the part. Both involve sandpaper like particles of varying particle size imbedded in our vise jaws. Depending on whether visible marking of the part is allowable on not, use the largest grit size available. 280 grit and up will not visibly mark the part, but will not retain the part as well as 100 grit. The rule of thumb is that for a given clamping force, the use of these coatings will increase retention by a factor of 2 to 3 times. These are proven products, the costs differ as well as the effectiveness. Below are two suppliers that we have used;

Power Drawbar Adjustment
Approximately every three months loosen three cap screws (101-02), raise quill and manually push the head assembly up and down to realign the socket to the drawbar. Re-tighten the three screws (101-02). |

When using the Kurt power drawbar, remember to raise the quill all the way up to the tool change position. Not getting the tool all the way up will result in excessive wear at the spline end. |

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 that 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 surface top and bottom so the movable jaw and nut ride freely. When finished assembling, lightly oil all machined surfaces to prevent rust. |

Never use an impact wrench on any Kurt vises, especially the DoubleLock Series. Also do not use cheater bars or hammers. Kurt vise handles are designed to give the maximum clamping force for the vise. Failure to follow these rules could result in broken parts and a voided warranty. |
