Custom Designed Machine for Manufacturing Bowling Balls.

Courtesy of Bespoke Machines


Our client is a specialist manufacturer of custom made machines. Having supplied machines for different industries, our client won a contract to build a machine to make the decorative grooves and marks for bowling balls.


The clients specification called for the ability to manufacture 50 balls per hour with a variety of marks and patterns. Bespoke Machines Ltd. used a 1 axis TRM motion controller with MAP software, a 1.2 Nm servomotor with 1000 ppr encoderm, a proximity sensor for home position and a custom TRM electrical cabinet. All wiring between the electrical cabinet and controller was pre-made at TRM's facilities allowing our customer to build a machine to meet and exceed his clients requirements. The machine is now producing 60 bowling balls per hour and is capable of making many more patterns than before.

Bowling Ball Patterns

TRM supplied all the electrical controls and motor mentioned above when the machine was 80% built, since all the wiring was pre-made it was quick to install and ready to start the initial tests soon after delivery. Today the machine is manufacturing bowling balls with more patterns and better quality than ever and still remain competitive with labour costs down and greater production.

In order to make the grooves, marks and patterns, the servomotor rotates the bowling ball with high accuracy. Then, using the digital outputs, the controller turns the tool motors On and Off. Using the controller’s capability for storing up to 100 user programs, different programs are created for making different patterns as shown on the photo above.

The controller was programmed using the Motion Application Programme ‘MAP’. ‘MAP’ has been used in a vast variety of machines and applications giving the user a greater control of costs, saving money and time on software development.

One of the great advantages of MAP is that it allows end users to create their own programs with no need for a skilled programmer. MAP has been used in different applications from Sash Windows Machines, Bowling Ball Machines, Tube Bending Machines, XYZ tables, Pallet Manufacturing Robots, rotary axes and milling machines to pharmaceutical mixers among other applications.


Point to Point move:
Moves a single axis from point to point with no acceleration, or velocity parameters. This command is mainly used by the profile generator or for holding  position.

Trapezoidal move:
Moves a single axis from point to point, using programmed acceleration and velocity parameters. If the velocity can not be reached the function will generate a triangular profile.

Linear Interpolation:
This function allows up to 4 axis to be linked together to produce a linear profile. Full use is made of the acceleration and velocity parameters.

Circular Interpolation
This function allows two axis to be linked together to produce a circular profile. Full use is made of the acceleration and velocity parameters.
