Broaching Machine Specialties
Broaching Machine Specialties builds a variety of standard lines of new broaching equipment and special machines for unique broaching applications.
Investigating the scuffing load carrying capacity of hypoid gear oils
A new test method has been developed consisting of a running-in procedure and a step test of up to 14 load stages as the main test phase, using a hypoid test gear.
Estimation of drag finishing abrasive effect for cutting-edge preparation in broaching tool
The performance of an abrasive mixture of SiC and Al2O2 at different grain sizes and percentages of mixture is used to prepare uncoated tungsten carbide broaching tools by a drag finishing process.
Calculating mounting distance tolerances
Although no reliable methods have yet been developed to calculate tolerances for the mounting distance in intersected-axes and crossed-axes gearing, required configurations of the gears in a gear pair are more commonly obtained by means of the ‘trial and error method.’
