Technical offer – HPR50 – Vertical manual milling head – manual mounting HPR50 FEATURES Vertical milling head HPR50 is designed for RET10X, RET10P, RET100B horizontal milling and boring machines as optional technological accessory. HPR50 milling head allows milling in parallel planes or drilling in perpendicular planes in relation to the spindle axis. Milling head is mounted manually on the headstock (centring hole of the spindle housing). Milling head is positioned manually. MAIN PARAMETERS Clamping taper Tool shank Max. transmitted power Max. spindle speed torque Speed transmission from machine spindle to milling head spindle Angle range of the rotary part Hydraulic power supply to the front of the headstock Total milling head weight BRIEF TECHNICAL DESCRIPTION Milling head consists of two compactly connected basic parts, which can be rotated against each other to achieve the required position of the milling head spindle. The angle of rotation in the milling head intersection surface is set by means of a socket handle after releasing the rotary part of the milling head. The rotary part of the head is fastened with screws on the periphery of the dividing plane. The angle setting can be read on the peripheral nonius scale. For precise setting of basic positions 4x90 °, the milling head is equipped with a lock. For more precise setting of the general position of the milling head spindle, it is necessary to use appropriate check and measuring tools. SPINDLE Milling head spindle is driven by the machine spindle and the direction of its rotation is identical with the direction of rotation of the machine spindle. Milling head interior includes the complete drive mechanisms (gear wheels) and bearing (in precision spindle bearings) of the head spindle.

Technical offer – HPR50 – Vertical manual milling head – manual mounting Tool is mechanically clamped to the milling head spindle using a set of disc springs. Tool unclamping is provided hydromechanically with the supply of oil pressure from the machine. Tool is inserted into and removed from the conical cavity of the milling head spindle manually. (This is applied also to machines equipped with an automatic tool changer in the machine spindle.) Control of clamping/unclamping a manually inserted tool is identical with the control of the machine clamping system. LUBRICATION Lubrication of the...
