The invention relates to an axial-force-controllable surgical bone drill using a brazed PCBN (Polycrystalline Cubic Boron Nitride) superhard material drill bit. The axial-force-controllable surgical bone drill has the advantages that the control accuracy is high and damages to brain tissues can be effectively avoided. A direct-current motor is arranged in the case of a drill body. The direct-current motor is connected with an intelligent integrated control system and a direct-current power supply. The output shaft of the direct-current motor is connected with a gear transmission device. The gear transmission device is connected with a drill bit chuck through a transmission shaft. A drill bit is installed on the drill bit chuck. A thrust bearing is arranged at the junction of the drill bit chuck and the transmission shaft. The thrust bearing is in close contact with a deformable element. The deformable element is in close contact with the case. The deformable element is positioned by using an elastic element. A resistance strain gage is bonded on the internal surface of the deformable element. The resistance strain gage is additionally connected with the intelligent integrated control system. A sealing device is arranged between the drill bit chuck and the case. The drill bit comprises a cylindrical basal body. A twist drill tip is arranged on the cylindrical basal body. A spiral groove is additionally arranged on the cylindrical basal body. PCBN superhard materials are arranged in the spiral groove and on the surface of the main rear blade of the drill bit.

In the scroll compressor of the present invention, the amount of oil supplied to the outer line side compression chamber and the inner line side compression chamber of the orbiting scroll wrap can be rationalized without impairing the strength of the wrap. The scroll compressor forms a suction chamber and a compression chamber between the fixed scroll and the orbiting scroll, and has a back pressure chamber on the back of the orbiting scroll platen, and is formed in an asymmetric tooth shape. A fluid outflow path for the outer line side compression chamber of the orbiting scroll wrap and a fluid outflow path for the inner line side compression chamber are formed on the orbiting scroll platen, and the outlet side openings of each fluid outflow path open to the tooth bottom of the orbiting wrap. The inlet side openings of each fluid outflow path are opened to the orbiting scroll table surface that slides with the fixed scroll, and a groove is formed on the fixed scroll table surface so that the inlet side openings of each fluid outflow path and the back pressure chamber follow the orbiting motion. Intermittently communicated communication section control tank. The communication section control groove is formed so that the pressures in the respective compression chambers at the start and end of the communication between the two compression chambers on the outer line side and the inner line side and the back pressure chamber are the same.
