Sine & Toolmakers Vises
Precision Sine Vises and Toolmakers Vises designed for accurate workholding in machining, grinding, inspection, and toolroom applications. Ideal for holding small to medium-sized workpieces with high repeatability and dimensional accuracy.
Overview
Sine and Toolmakers Vises are precision workholding devices commonly used in toolrooms, grinding operations, CNC machining, and inspection environments. They are designed to provide accurate positioning, repeatability, and secure clamping of workpieces.
Sine Vises
A sine vise is a special-purpose precision vise designed to hold a workpiece at a highly accurate angle. The angle is set using gauge blocks based on the sine of the desired angle, hence the name sine vise.
- Screwless precision vise design
- Supported on two hardened and ground cylinders
- One cylinder acts as the pivot axis for angular adjustment
- Angle setting calculated using sine principles and gauge blocks
- Ideal for grinding, EDM, milling, and inspection operations
Toolmakers Vises
Toolmakers vises are compact, high-accuracy vises designed primarily for small precision parts. They are widely used when workpieces must be transferred between machines without losing alignment.
- Compact and lightweight design
- High clamping accuracy and repeatability
- Multi-step latch or screwless locking mechanism
- Lock-down jaw design minimizes jaw lift during clamping
- Commonly used on surface grinders, milling machines, drill presses, and inspection tables
Typical Applications
- Surface grinding and precision grinding
- CNC and manual milling operations
- Toolroom and mold-making applications
- Inspection and measurement setups
- Multi-machine workpiece transfer without re-clamping
Advantages
- High dimensional accuracy and repeatability
- Minimal workpiece distortion
- Suitable for precision angular machining (sine vises)
- Easy relocation of workpiece between machines (toolmaker vises)
- Ideal for small and precision components
Construction & Quality
- Manufactured from hardened and ground tool steel
- Precision-ground jaws and reference surfaces
- Designed for long-term accuracy and durability
- Corrosion-resistant surface finishes available
Limitations
- Typically limited to small or medium-sized workpieces
- Fewer accessories compared to CNC or machinist vises
- Manual setup required for angular positioning
