2. Safety Information
Always observe the following safety precautions when using the vise:
- Wear appropriate personal protective equipment (PPE), including safety glasses, at all times when operating machinery or handling workpieces.
- Ensure the vise is securely mounted to a stable workbench or machine table before use.
- Do not overtighten the vise. Apply sufficient clamping force to hold the workpiece securely without deforming it or damaging the vise.
- Keep hands and fingers clear of the clamping area during operation.
- Inspect the vise for any damage or wear before each use. Do not use a damaged vise.
- Keep the work area clean and well-lit.
- Do not modify the vise. Use it only for its intended purpose.
3. Product Components and Features
The Accusize Precision Screwless Toolmakers Vise is engineered for high accuracy and durability. Key features include:
- High Precision: Achieves parallelism of 0.003 mm/100 mm and squareness of 0.005 mm/100 mm.
- Robust Construction: Made from 20CrMnTi steel, carburized to a surface hardness of HRC55-60.
- Screwless Design: Provides quick and efficient clamping.
- Anti-Lift Mechanism: The movable jaw pulls into the base at a 45 to 60-degree angle, preventing workpiece lifting during clamping.
- V-Groove: Integrated V-grooves on the jaws allow for secure clamping of round workpieces.

4. Setup
- Unpacking: Carefully remove the vise from its packaging. Inspect for any signs of shipping damage.
- Cleaning: Wipe down the vise with a clean, lint-free cloth to remove any protective oils or debris.
- Mounting:
- Position the vise on a stable machine table or workbench.
- Utilize appropriate T-nuts and clamps (not included) to secure the vise firmly to the table through the mounting slots on its base.
- Ensure the vise is aligned correctly for your application.
- Initial Adjustment: Loosen the clamping screw slightly to allow the movable jaw to slide freely.

5. Operating Instructions
- Workpiece Placement:
- Place the workpiece between the fixed and movable jaws.
- For round workpieces, utilize the V-grooves for enhanced stability.
- Clamping:
- Slide the movable jaw towards the workpiece until it makes contact.
- Use the provided hex key to tighten the clamping screw on the movable jaw. Turn clockwise to secure the workpiece.
- Tighten firmly but avoid excessive force, which can damage the workpiece or the vise. The screwless design ensures consistent clamping force without lifting.
- Operation: Once the workpiece is securely clamped, proceed with your machining, inspection, or assembly tasks.
- Unclamping: Turn the clamping screw counter-clockwise to release the movable jaw and remove the workpiece.

6. Maintenance
Regular maintenance ensures the longevity and continued precision of your vise:
- Cleaning: After each use, clean the vise thoroughly to remove chips, coolant, and debris. Use a brush and compressed air if necessary.
- Lubrication: Periodically apply a light coat of machine oil to all sliding surfaces and the clamping screw mechanism to prevent rust and ensure smooth operation.
- Inspection: Regularly check the jaws and base for wear, nicks, or damage. Ensure the clamping screw operates smoothly.
- Storage: Store the vise in a clean, dry environment, preferably in its original protective case, to prevent corrosion and damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Workpiece not holding securely | Insufficient clamping force; debris on jaws; worn jaws. | Increase clamping force; clean jaws; inspect and replace jaws if severely worn. |
| Movable jaw sticks or is difficult to slide | Lack of lubrication; accumulated debris; minor damage to sliding surfaces. | Clean and lubricate sliding surfaces; inspect for burrs and carefully remove if present. |
| Vise not stable on machine table | Improper mounting; loose clamps. | Ensure vise is securely clamped to the table using appropriate hardware. |
