APPLICATIONS
Carbide threading inserts for Standard and Petroleum
Industry thread forms. Circular form tools for Aircraft
and Automotive Industries.
MATERIALS
Diamond wheels for Carbide, Ceramics and Cermets.
Also Glass, Stone, Carbon, Reinforced Plastics and Nimonics.
CBN Wheels for HSS, Tool Steels, Stellites etc.
TOLERANCES
Very accurate wheel dimensions +0.003mm, angles +3'.
Less accurate wheels available for less exacting tasks.
Conditions of machine tool and especially spindle affect
profile geometry.
WHEEL
LIFE Between 3 and 5 meters for a Diamond Wheel
Grinding Carbide. Life is influenced by a number of
factors including:
- Coolant
type, volume and treatment (see below).
- Machine
tool conditions.
- Minimum
radii.
- Materials
being ground.
- Machine
operator.
CBN
Wheels grinding HSS can achieve in excess of 100 metres.
FEED
RATES Very accurate wheel grinding carbide cut at
between 15 to 25mm per minute at full depth of form.
Less accurate wheels will cut more quickly. Rate of
cut is affected by the following:
- Conditions
and age of wheel.
- Grit
size - determined often by surface finish or minimum
radii.
- Coolant
supply.
- Condition
and type of machine tool.
- Wheel
diameter.
- Width
of component.
- Depth
of cut.
SETTING
UP Cranden wheels should be clocked on the machine
using the groove or flange supplied. All Cranden wheels
are manufactured with minimum run-out within the wheel.
Typically a standard wheel will run-out less than 0.003mm
laterally and 0.002mm radially.
MULTIPLE
PROFILES Wheels can be produced with more than one
form when producing large volumes. Multiple forms can
be the same or different as long as they are compatible.
Forms can be sited with a toleranced pitch for grinding
two forms simultaneously or for ease of indexing. The
maximum number of forms is determined by profile and
wheel size.
