What other manufacturer knows more about sating the throngs of coffee addicts lined up outside your cafe in the bleary morning hours? Rancilio moves beyond high-end commercial espresso makers with their professional line of grinders so that you can control everything about the shots of liquid energy your baristas craft for your customers.

The smallest of the MD line, the MD 40 is a Semi-Automatic grinder constructed of die-cut aluminum wrapped in polished steel and topped with a super-large, blue tinted and UV protected bean hopper designed to hold over a pound of roasted espresso beans. Appointed with tempered steel grinding plates that shred through beans, the MD 40 can produce over 7 pounds of fresh espresso in the span of an hour. Rounding out its features, the integrated doser makes it easy for the busy barista to tap out just the right amount of grounds into the waiting portafiliter or press. Simply put, this grinder is a must-have for any cafe looking for quality, consistency and productivity from their grinder.

How the Rancilio MD 40 Commercial Burr Grinder Works

  • Fill the bean hopper with beans
  • Adjust to the appropriate setting
  • Turn on grinder
  • Read the manufacturer manual for full instructions on operation

Features & Functionality of the Rancilio MD 40 Commercial Burr Grinder

Discover the professional features and automatic functionality that makes Rancilio grinders the preferred choice among some of the world's finest cafes.

  • Commercial Capacity: The powerful motor and grinder unit of this machine can turn beans into espresso in two seconds flat. Designed to deliver over 7 pounds of ground coffee in an hour, there isn't a coffee shop or cafe around able to provide demand that exceeds the Rancilio's ability to deliver.
  • Steel Burr Grinder: The heavy duty 55mm burr grinding plates are made of tempered steel and operate at a super low RPM (rotations per minute) to prevent unnecessary heat build-up and transfer to your coffee beans. The grinder's motor is housed in thermal protection to prevent overheating.
  • Coffee Dosing System: The MD 40's dosing system adjusts from 5 to 10 grams per dose.
  • Semi-Automatic: You'll manually adjust the machine to fill the dosing chamber, which gives you a tad more control over output.
  • Great Bean Hopper: Made of blue tinted molded plastic with a black lid, the Rancilio hopper keeps 1 pound of coffee beans well sealed so they remain fresh and ready to grind. The blue tint is designed to prevent UV rays from damaging the beans while they are in the hopper.
