HI STORY CMA Machine Tools is a family business founded in Alzira (Valencia) in 1989. We are specialized in the production of machinery for drilling, milling and threading metal. FEATURES All the machines produced are characterized by an excellent value for money, as well as great versatility and efficiency. They are ideal for those companies in the steel structure fabrication and metal processing industry. FACILITIES Our factory has a total area of 9000 m2 located in the Parque Empresarial El Pla. Our factory is made up of 3 different buildings that include a parts warehouse, a paint shop, a welding shop, an assembly room and a machining department, in addition to our offices. 1
MACHINING CENTERS CMA CNC machining centers are characterized by having a moving head in 3 axes (X, Y, Z). They are designed for drilling, tapping and milling in sheet metal, flat bars, profiles and steel tubes. The head is designed and manufactured in CMA with internal lubrication (up to 60 bar) that allows working with the latest technology in tools. Each and every one of the operations is perfectly programmable using a PC controller with CMA's own CNC software. The spindle portal is guided along the table on linear guides, hardened and precision mounted on the machines body. The X axis portal is driven by a helical rack pinion and the Y and Z axes by a ball screw. All models (3RD, GRD and BRD) can be programmed for drilling, thermal drilling, tapping, milling and chamfering operations. One of their advantages is the precision of the X/Y/Z path and the wide range of operations they can perform. The attractive price of the CMA machining centers in relation to our competitors, as well as a large variety of additional options and a successful design make the CMA machining centers very versatile. 2 BRD and GRD machining centers
3RD CMA MACHINING CENTER The 3RD model is the most flexible vertical machining center on the market. Their size varies from 3m to 10.5m long, but, in addition to our standard sizes, we design and manufacture custom machines to meet the needs of our customers. This model is capable of high-speed drilling and milling of large parts in one setup with less repositioning. Our motion control system is the most advanced CNC controller available, giving you the power and flexibility for both your small and large machining applications. AVAILABLE MACHINING RANGES: For X-axis = 3000 / 4500 / 6000 / 7500 / 9000 / 10500 mm For Y-axis = 600 mm 3
3RD CMA MACHINING CENTER The drilling, tapping and milling operations are carried out by means of a head with an asynchronous SERVO motor with a power of 13.1 kW. The motor drive is transmitted directly through the pulleys and toothed belt. Depending on the relationship applied in the pulley-belt relationship, we obtain a specific torque and the maximum speed of the head rotation. There are 5 different speed ranges (2000-6000rpm) to choose from. The clamping of the tools in the spindle is on the BT40 cone. It has a safety laser scanner that allows working in different areas, an endless screw for the extraction of coolant and chips and, in addition, a mobile control panel on a linear guide that allows it to move along the machine.

GRD CMA MACHINING CENTER The GRD model is the most flexible vertical machining center on the market designed to produce larger parts than the CMA 3RD model. Its size varies from 3x1.4m to 10.5x3m in length, but, apart from our standard sizes, we design and manufacture custom machines to meet our customers' requests. The GRD is capable of high-speed drilling and milling of large parts in one setup with less repositioning. Our motion control system is the most advanced CNC controller available, providing the capability and flexibility for both your large and small machining applications. AVAILABLE MACHINING RANGES: For X-axis = 3000 / 4500 / 6000 / 7500 / 9000 / 10500 / 12000 mm For Y-axis = 1400 / 1800 / 2000 / 2500 / 3000 / 3500 / 4000 mm 5
GRD CMA MACHINING CENTER The drilling, tapping and milling operations are carried out by means of a head with an asynchronous SERVO motor with a power of 13 kW or 30 kW with direct transmission. The motor drive is transmitted directly through the pulleys and toothed belt. Depending on the relationship applied in the pulley-belt relationship, we obtain a specific torque and the maximum speed of the head rotation. The standard model of the GRD model includes a chip conveyor, an automatic storage for 24 BT40 tools. It has a safety laser that allows working in different areas, an endless screw for the extraction of coolant and chips and, in addition, a mobile control panel on a linear guide that allows it to move along the machine.

BRD CMA MACHINING CENTER Our BRD model is designed for drilling, tapping and milling profiles and beams with a 3-axis moving head (X, Y, Z). The sizes of this model can vary between 12m or 16m in length and 610mm or 1050mm in height. All its operations are programmable through the PC controller with CMA software. In addition, the spindle gantry is guided along the table on linear guides, hardened and precisely mounted on the machine body. All this with a competitive price to help our customers improve their production. AVAILABLE MACHINING RANGES: For X-axis = 12000 / 16000 mm For Y-axis = 600 / 1050 mm 7
BRD CMA MACHINING CENTER It's possible to use HSS drills and high speed carbide drills. It can process both large and small parts. It can works in multiple zones. It has easy loading/unloading of parts. It's simple to use and program. This model has a laser for the rapid detection of the 0 point of the piece. In addition, our BRD has a hydraulic rammer that allows movement in X while the part is clamped, making milling, interpolation drilling and marking operations possible. The most optimal speed range is 50-3000 rpm for our BRD model, which allows to make a thread up to M24 and to drill with a full drill up to a maximum of 42mm. Some of the most important capabilities of this model are: BRD CNC machining center 8
