Raloid Tool Company, Inc. Mechanicville, New York

The Raloid 20" CGIM Contour Grinder was developed to accurately grind bonded and riveted shoe and lining assemblies with automatic loading and unloading capabilities for maximum efficiency and performance from operator free loading, grinding, and unloading functions. The grinder has capabilities with selected options to grind the outside radius of the lining as well as the leading and trailing chamfers if required tangent to the radius, at either the (3) o’clock or the (6) o’clock grind positions, with appropriate squareness and true locating datums on the shoe assemblies.

The Gage is a precision product designed for accurate, repeatable, reliable performance with the manufactured parts built to extremely close tolerances and with the purchased components selected to rigid specifications. Each Gage is designed for specific shoesegment lining assembly and a specific tooling set-up on the Raloid 20" CGIM Contour Grinder for shoesegment lining assemblies. The Gage assembly can measure the deviation from the proper radius, amount of drop at each end of the ground assembly, as well as the squareness of the lining relative to the locating datums and locations all in a single pass.

Both the SE-F8 and the SE-F4 Disc Brake Bonding Clamps are designed to work with the DBT-77 and the DBT-88 Brake Assembly Tables and both clamps have the belleville spring system of the Full-Contact Clamps. The SE-F8 clamp holds 8 smaller shoe and lining assemblies that are 3-12" in overall length or less with no rear flanges or projections. The SE-F4 clamp holds 4 larger shoe and lining assemblies that are up to 8" overall length. The clamp has been designed so that the pressure bars are narrower and shorter to fit between the flanges and projections of the larger shoe.

As you already know, the Raloid Pneumatic Clamping Table, when used with Raloid’s Clamping System, is the perfect machine for clamping and releasing brake shoes in the bonding process. Simple and reliable, it has become an industry standard. Plant and production managers asked Raloid to automate the turning of the clamp jackbody. This would increase throughput, reduce workers’ repetitive wrist motion complaints, and eliminate inconsistencies in clamp pressure observed when different workers turn the jackbody by hand. After long, exhaustive research and field testing, Raloid is proud to announce the development of the Raloid Autoclamp.

Full Contact Clamps are used whenever there is a need to sustain high speed production of top quality bonds, especially on the newer weak-webbed brake shoes. The Full Contact Clamps are designed to support the underside of the shoe table along both sides of the web so that web strength is of minor importance during the bonding procedure. The PT4-200 series of Full Contact Clamps is designed with the Acme threaded jack, belleville spring system for pressure maintenance, and the fixture assemblies. The series is available for all foreign and domestic U.S. cars and their use avoids shoe bending that can occur in many of those models. They are available in both Metric and English sizes. Since many of the shoes vary only a small amount, Raloid Tool Company, requests that you send samples of the exact shoe you are bonding so that the Full Contact Clamps can be manufactured to those specifications.

The Raloid Electric Conveyor Ovens are ovens designed specifically for use in the bonding of friction materials. These ovens utilize electric power for their radiant heat elements, and are regulated by two automatic solid state controls. The first control for each oven section is a Dual Setpoint Digital Temperature Control. The first setpoint controls the auxiliary heating elements which are cycled appropriately to enable quick heating of the oven and of the cold brake shoes as they enter each section. The second setpoint controls the main heating elements and cycles them as required to maintain the optimum temperature.
