Relock Vice System 19752 - 19768
What is...
Materials
The ReLock® Vice System combines high manufactured tolerances with unequalled versatility in providing two-station and 8-station production vices.
ReLock CNC Vices, available with machinable soft jaws, hard jaws, master jaws and parallels, or fixture plates, allow the machinist a variety of configurations with the same vice. Bodies are manufactured from 80,000 PSI ductile cast iron, and guide parts are flame hardened and ground to accuracies of ±0.0005". Manual and hydraulic two-station and 8-station vices are available in widths of 4", 6" and 8.
General Guidance

Features
Optimised Table Space
Compact modular design allows a multitude of mounting configurations. Vices can be mounted close together without hindering removal or attachments of jaws. The ReLock 8-station (shown) is ideal for horizontal machining centres, as well as with rotary indexers on vertical machining centres.
Loacting and Mounting
Locating and mounting options are simple and accurate. The bottom surface of the system has four precision dowel pin holes for locating and four drilled and counter bored holes drilled through from the top surface for rugged mounting. Side toe clamp slots are also incorporated for mounting.
ReLock Chip Shields
ReLock's unique three piece telescoping chip shield wraps completely around the SnapLock knuckles, keeping chips from getting into the vice's clamping mechanism. Shields can quickly and easily removed from maintenance purposes.
Single Station Conversion
Used in conjunction with SnapLock carrier jaws, the conversion plate allows the ReLock system to be converted from a double to a single station vice - ideal for larger workpieces.
Center Jaw Location
The ReLock's center jaw locating studs allow quick jaw mounting and indexing to accuracies of ±0.0005". Fool proof pin eliminates the possibility of the jaws being accidentally mounted in reverse.
SnapLock Knuckle
Exclusive SnapLock Knuckle allows SnapLock soft jaws and SoftLock carrier to be attached and removed in seconds.
Auto Offset Mechanism
Exclusive automatic offset mechanism allows non simultaneous workpiece clamping and unclamping to one of the three optional offset settings: 4” and 6”: 0.030”, 0.125”, or 0.250”; 8”: 0.125”, 0.250”, or 0.375”. The offset setting is the distance the rear jaw backs away from the workpiece before the front jaw begins to back away from the workpiece.
Technical Specs
a - SnapLock Carrier Jaws
SnapLock Carrier Jaws allow mounting of AccuSnap and QuickChange Master jaws by using an industry standard bolt size and pattern. Carrier jaws snap on and off the SnapLock knuckles in seconds.
Machinable Fixture Jaws
AccuSnap and QuickChange Machinable Fixture Jaws can be customised quickly to fixture a wide range of workpieces. The jaws snap or slide in and out of the master jaws in seconds. Available in either aluminium or pre-hardened steel.
Modular Workstops
AccuSnap Modular Workstops quickly mount to parallels in many different positions. As many as three stops can be mounted to a single parallel to accomodate multi-piece set-ups.
b/c - AccuSnap and QuickChange Master Jaws
SnapLock Carrier Jaws allow mounting of AccuSnap and QuickChange Master jaws by using an industry standard bolt size and pattern. Carrier jaws snap on and off the SnapLock knuckles in seconds.
SnapLock Reversible Machinable Fixture Jaws
SnapLock Reversible Machinable Fixture Jaws are the most versatile method of fixturing on the ReLock System. Customising options are endless. Jaws can be machined on two faces for additional set-up. Manufactured from high quality aluminium
Universal Workstop
The Universal Workstop easily mounts to the side of the ReLock in numerous positions. Optional extension is available for larger workpieces.
d/e - AccuSnap and QuickChange Parallels
AccuSnap and QuickChange Parallels are designed for a multitude of set-up variations when you need to position a workpiece between hardened jaws. AccuSnap parallels snap in and out of the AccuSnap Master Jaws in seconds. QuickChange parallels slide into position via a dovetail slot and gib.
Fixture Plate
Ideal for a wide variety of fixturing applications, such as holding many small parts or parts with difficult clamping or locating requirements. Fixture Plates can be attached or removed in seconds and are offered in two widths. Manufactured from high quality aluminium.
Workstop Presetting Gauge
The AccuSnap Workstop Presetting Gauge, in combination with a standard micrometer, allows you to precisely preset your modular workstop positions in relation to the X, Y, and Z machine datums.
Single Station Conversion Plate
The Single Station Conversion Plate quickly converts the ReLock from double station to single station vice for larger workpieces.
FAQs
Initial Cleaning
After unpacking your vice and checking the contents, wipe all surfaces with a clean rag or cloth to remove any debris or rust inhibitor that is present. This will ensure that the vice will operate at its maximum efficiency.
Operating Instructions
Behind the rear knuckle (opposite the handle end) you will find two hex screws. One is to adjust the automatic offset mechanism (discussed later) and the other is to adjust the brake mechanism for the vice (see drawing A)
Simply tighten the brake screw in a clockwise rotation until it is snug. DO NOT OVERTIGHTEN. Failure to set brake properly will:
- not allow vice to open and close properly and/or
- will not allow the automatic offset mechanism to operate correctly
- Offset Mechanism
- Break Assembly
Jaw Closure Warning
Do not fully close vice without jaws properly mounted on vice knuckles.
The ReLock vice should only be fully closed when:
- a three piece SnapLock Machine Jaw Set is on vice
- a SnapLock Carrier Jaw Set and AccuSnap or QuickChange Master Jaw configuration is on vice
Failure to do this could result in damage to the centre chip shield
Automatic Offset Mechanism
Behind the rear knuckle (opposite the handle end) you will find two hex screws. One is to adjust the automatic offset mechanism and the other is to adjust the brake mechanism for the vice (see drawing A on previous page). The automatic offset mechanism allows the user to set the distance that one jaw will break (i.e. open) before the next jaw breaks. The offset can be set to three distances: .030, .125, .250. The automatic part of the mechanism allows the user to change workpiece sizes without any further adjustment to the offset mechanism. For example: You set your offset to .250 and you are setting up a job where the workpiece is a 3" square then you switch to the next job where the workpiece is a 4" square, the offset mechanism will automatically break the back jaw .250 for both workpieces. Similarly, you can change the offset for both jobs simply by turning the adjustment screw to the desired distance. This feature is especially useful in a horizontal machining centre application. This will prevent both workpieces from falling out of your fixture at the same time and allows you to set the distance.
Jaw Opening & Closing
When closing the vice, the front jaw (handle end) will open first. Once contact is made to the workpiece, the back jaw will move. When contact is made by the back jaw both jaws will tighten together to your desired presuure. DO NOT OVER-TORQUE VICES. OVER-torquing will cause damage to the vice and could cause harm to the operator
Recommended clamping pressures:
- 4": 0-6,000 lbs.
- 6": 0-12,000 lbs.
- 8": 0-16,000 lbs.
