Our Range of CNC Workholding Clamps & CNC Fixtures

1. Collets –

A key component of CNC turning, a collet works in tandem with the spindle. When machining, collet chucks provide a consistent gripping force, enabling you to safely operate the machine at higher RPMs and reducing your run-time. Benefits of collets also include:

  • Fast set-up time
  • Higher accuracy
  • Custom collets are effective for off-centre CNC turning or holding odd-shaped parts

At Hyfore, we supply a wide range of ER, Autolock, R8 and 5C collets.

C-Style collets

C-style collets are cylindrical workholding devices used to clamp machine spindles for accurate, high-speed rotary machining. The spindle is inserted into the collet, and the collet is tightened using a nut, which squeezes the slits in the collet shut so it firmly grips the spindle. C-style collets are available in various sizes for a variety of applications.

2. Self-centring machine vices –

Compact mechanical, pneumatic, hydraulic and electro-mechanical centre-clamping vices are available from Hyfore’s catalogue. We provide vices in a variety of sizes and assembly variations.

Discover our range of centre-clamping vices for both conventional and CNC machining.

Spreitzer MZR

Mechanical centre-clamping vices that are used as a cost-effective solution for powerful raw material clamping.  There is no need for pre-stamping and can be used on multi-axis machining centres and automation systems, with the rigid base body being optimised for 5-axis. These are best suited for use where maximum centering and repetition accuracy is not required. The units include one-piece reversible jaws with integrated grip steps, allowing for clamping range to be easily altered and providing maximum length.

Spreitzer MZU

With the option of choosing reversible grip or soft block jaws, the MZU vice series allows the user a high level of flexibility and accessibility for multi-axis machining centres, even for short cutting tools. The reversible jaw distorts the surface of the workpiece, allowing for an increased holding force, with a protective coating applied to the product to eliminate the risk of premature wear and tear.

Spreitzer MZQ

The MZQ vices allow for the quick changing and replacement of jaws without the use of tools. They are designed specifically for use within pallet automation and have over 80% less setup costs than other vices. With reversible step jaws, these products allow maximum accessibility and have a large clamping range. Ideal for daily repeated retooling and has significant time savings when used on automation systems.

4. Expanding mandrel –

Mandrels work by expanding within the bore of a workpiece, coming into contact with 95% of the holding surface and preventing distortion during the precision machining process.

The key features of our expanding mandrel include:

  • Parallel gripping with maximum torque
  • A built-in safety stop, eliminating the risk of over-expansion
  • The ability to interchange collets

Our expanding mandrel

We provide a wide selection of Collet Style Expanding Mandrels, manufactured by industry leading partner Hardinge, offering solutions to difficult machining problems for turning, milling, grinding, assembly and automation applications. We guarantee exact workpiece lengths, even for particularly long parts, as our bespoke line of mandrels have extremely high stability.
