Hiring Problems…Time to Automate!

Wednesday, September 1, 2021 | News

With the current labor shortage and cost, it may be time to justify moving up from the single-sided labor-intensive Surface and Blanchard grinding and take that leap into Single and Double Disc Grinding with C&B Machinery.

Case Example:

A Full-time dedicated operator was needed to load/unload and grind Push Rod Seats on a Blanchard grinder to get 500 parts per hour.

Dedicated Operator Hand Loading Blanchard Grinder

Solution:

C&B built a custom Single Disc grinder complete with automatic load and unload which only required 20% of the operator’s time and increased their productivity to 3600 parts per hour.

C&B Machinery Expands the Models and Features Available on Its Line of CBV Series Clamp Bore Grinders.

Tuesday, August 21, 2018 | News

C&B Machinery’s lineup of Vertical Clamp Bore micro-finishing grinders has been expanded yet again! C&B continues to strive to be an industry leader in meeting customers’ ever-growing needs for flexibility, throughput volumes, integration with plant automation, and maximizing perishable tooling life.

Our single spindle models can be an economical choice for lower volumes and lower tooling costs. Our double spindle models work well for applications where different work holding at each station has advantages and volumes are a bit higher. To the other extreme, our rotary index models can offer tooling flexibility and the very highest level of throughput.

We now offer a higher-speed grinding spindle option to maximize efficiency for customers using CBN grinding wheels vs. conventional free-cutting, self-dressing vitrified wheels.

The CBV Series offers multiple part handling options including operator hand load/unload, robotics integration (Fanuc Authorized Integrator), gantry load/unload with part flipping capabilities, and in-process gauging with load pre-check for stock and runout. The gauge fixture is designed for quick adjustments with no tools required. Software is designed for control of stock removal on each side and part orientation entering or exiting the cell. Error proofing for part load and part type can also be designed into this system.
