These chucks are used in the manufacture of broaches and thread rolling dies to include Mat threads.

Table Dressing

Table dressers are used to profile the grinding wheel and the come in a variety of types to include:

• Single point diamonds
• Chisel diamonds
• Rotary dressing discs
• Profile and flat rolls.

Application

• Used for development work before a profile roll is manufactured.
• Production work where a large number of different profiles are required.
• Used with the Grips programming system for contour generation.

High Frequency Grinding Spindle

High speed spindle located under the wheel head so that the correct surface speed of the wheel can be maintained to provide the optimum grinding performance. Small grinding wheels sometimes have to be used due to clearance requirements.

Internal Spindle

This application uses CBN grinding wheels and a horizontal spindle for the manufacturer of stator hydraulic components. The machine is equipped with special thermal compensation due to the condition of the grinding wheel.

Rotor Manufacture

This application use conventional or CBN grinding wheels and a horizontal spindle for the manufacturer of Rotor and vane slots for hydraulic components. The machine is equipped with special thermal compensation due to the condition of the grinding wheel.

Continuous Overhead Dressing

Continuous overhead dressing where the roll feeds continuously into the wheel giving the following benefits:

• Profile is maintained
• Wheel is conditioned
• Wheel is clean and sharp
• New grains are exposed.

Application

• Heat sensitive materials
• Difficult to machine materials

In Process Overhead Dressing

Using the PEA K 37 on a Blohm Jung machine, a diamond holder can support 6 diamonds so different radius diamonds can be kept in the machine. The machine can check the profile of the diamonds and adjust for wear in the profile. The same machine can also offer a disc so that continuous dressing can be performed whilst grinding.

Application

• Small profile parts with profiles up to 50mm wide
• Punches

In Process Overhead Dressing

In Process dressing where the roll feeds intermittently into the wheel giving the following benefits:

• Profile is maintained
• Wheel is conditioned to give the best grain exposure
• Wheel is cleaned
• New grains are exposed
• Cost saving over continuous dressing with a little loss of performance

Application

• Heat sensitive materials
• Difficult to machine materials

Rotary Tables

The machines can be equipped with single and double tables to enable 5- axis machining of complex parts. These tables allow the manufacture of large radii by rotating the part under a given point of the wheel to create a radius.

The tables allow simple parts to be machined on various sides which enables to part to be machined in one set up.

Applications include

• Nozzle guide vanes
• Turbine blades
• Seal segments
• Compressor blades
