MACKMA - BTT Series - Metal Chip Briquetting Machines [made in Italy]

The Mackma briquetting machine range, versatile and compact solution, compresses metal shavings and recovers processing oil or emulsified coolant.

Able to briquette iron, aluminum, steel, stainless steel, cast iron, copper, brass, bronze and even some types of plastic. The machine works automatically, can be timed and can be interfaced with lathes or machine centers.

The BTT Line Briquette Machines feature all-inclusive technology, including advanced control and automation systems to maximize efficiency. These machines are designed to be intuitive and user-friendly, reducing staff training time and enhancing productivity.


The Mackma BTT50 Briquette Machine is the most compact in its class, offering advanced technology within a footprint of just 80×120 cm. Its height is adjustable, ranging from a standard 110 cm down to 60 cm or up, depending on the customer’s needs. This machine compresses

shavings, reducing their volume by up to 90% with a pressure of 1000 Kg per cm² and extracts 98% of the liquid present in the shavings. It features a 50-liter liquid collection tank, a float, and an automatic pump that directs the liquid to the central processing unit.

It has various accessories such as an external shredder to reduce the size of long chips or skeins; an external hopper with vibrator for shavings that tend to compact; an integrated drainage system for chips with a high percentage of oil; an ultrasonic level sensor to check the filling status of the hopper.

The main advantages of using Mackma briquetting machine are:

Volume reduction -70%
Constructed with high-quality materials - long-lasting durability and reliability.
Reduction of handling and transport costs -80%
