The blurb says:
As for the HB model, the HBM lathe is a high-end bench lathe made with all the parts (size, reference, dimension, brand) that have made the reputation of our HB1 and HB2 models: bench, shafts, pulleys, bearings, motor, fan support, fans, claw, rotating tip, etc … Its sliding head keeps perfect alignment while creating a turning side in the air adjustable in length. The motor located in the rear part is fully integrated into the drive head with transparent door for access to the pulleys and tensioner. Without doubt the most technical, robust and precise manual bench lathe on the market.
