The CFB130 CNC Floor type horizontal boring & milling machine is a top-grade numerical control machine tool with independent intellectual property right, is developed by our company via a modular method through borrowing ideas from advanced technologies at both home and abroad and carrying out computer three-dimensional moulding and finite element analysis. It can work together with related accessories to carry out part milling, drilling, boring, tapping, thread processing and multi-procedure processing for two-dimensional and three-dimensional curved surfaces. 

2.1 Big basic parts such as the lathe body, the columns, the slide carriage, the headstock, and the back tail barrel are all high-strength resin bonded sand iron castings and receive two times of heat ageing treatment.

2.3 The Material Forming the Main Shaft: 38CrMoAlA. The surface of the main shaft undergoes nitrogen treatment and finishing with a hardness of above HV900.

2.4    The Guide Rails: a Schneeberger MR heavy-duty roller straight line guide rail made in Switzerland is adopted for X-direction guide rail, a sticking slide rail for Y,W-direction guide rail. All items of slide rail are the sliding rail, X-direction chosen for the whole or part steel guide rail.

.2.5 The Feed Mechanism: the feed mechanism, which adopts X, Y,Z, W coordinate feeding modes, is driven by an AC servo motor. The mechanism consists of a reduction box and a preload ball screw cut pair. The screw nut is a double-nut structure with an adjustable gap.

2.6 The Balancing Mechanism: the headstock adopts a counterweight balancing device with two-point suspension, double-guide and rollers.

2.7 The Hydraulic System: famous brand hydraulic elements with their mounting size meeting international standards are adopted.

2.8  The Lubrication System: the X,Y,Z,B,W coordinate guide rails and the ball screw nut pair are lubricated by an automatic lubrication device with set time and fixed quantity; a main shaft transmitting gear and a bearing thereof are lubricated by circulating cooling oil; and the main shaft bearing and the screw bearing are lubricated by grease.

2.10  The detecting element: the X , Y axes adopt grating rules and B axis adopts grating circular to form fully closed loop position detection; and the W axis adopts a coder to form semi-closed loop position detection.

Ⅲ. Coordinate Definition

The coordinates are defined as follows:

3.1 The transverse movement of the column and the slide carriage on the lathe body: X axis

3.2 The up-and-down movement of the headstock on the column: Y axis

3.3 Axial travel of boring axis: W axis

3.4 The longitudinal shift of the front-mounting table: V axis

3.5 The swiveling of the table: B axis

3.6 The slider travel of fixed facing head: U axis
