Precision CNC Tool Holders, Milling Chucks and Spindles Parfaite
Parfaite precision HER collet chucks, BT-HY hydraulic expansion holders, BTT-CR shrink fit holders, BT-PFC power milling chucks and built-in motorized spindles. Engineering tooling selection for CNC machining.
HER High-Torque Precision Collet Chucks
Parfaite HER precision collet chucks are built for high-feed and high-speed CNC milling. Featuring a patented trapezoidal thread design on the clamping nut, the tooling system delivers up to 2.3 times higher clamping torque than conventional ER chucks with runout within 0.005 mm.
- BT30, BT40, BT50 and HSK-A63 shanks with HER11, HER16, HER20, HER25, HER32 collet sizes
- Precision end milling, reaming, drilling and tapping across alloy steels and aluminum
- Runout within 0.005 mm at 4D projection, precision dynamic balancing on all shanks
- Precision HER-HP collets, balanced clamping nuts, coolant seals and torque wrenches
BT-HY Precision Hydraulic Expansion Chucks
Parfaite BT-HY hydraulic expansion chucks utilize pressurized hydraulic fluid to achieve uniform 360-degree tool gripping with runout within 0.003 mm. The internal fluid chamber dampens cutting vibrations, substantially improving surface finish and extending carbide cutting tool life.
- BT30, BT40, BT50 and BTT shanks with clamping bores from 6 mm to 32 mm
- Precision finishing and semi-finishing of complex injection mold cavities
- Runout within 0.003 mm, high-speed dynamic balancing, AD form internal coolant
- Piston pressure screws, internal hydraulic chambers and reducer sleeves
BTT-CR Monolithic Shrink Fit Tool Holders
Parfaite BTT-CR shrink fit chucks feature a monolithic body machined from high-tensile hot-working tool steel with simultaneous dual taper and face contact. The slim nose profile provides unimpeded clearance into deep cavities while maintaining runout repeatability within 0.003 mm.
- BTT30, BTT40, BTT50 and HSK-A63 tapers with clamping diameters from 3 to 25 mm
- High-speed 5-axis mold cavity milling and deep profiling in alloyed tool steel
- Runout within 0.003 mm, symmetric monolithic geometry for high-feed profiling
- Monolithic tool bodies, internal depth stop screws and coolant tubes
BT-PFC Heavy-Duty Power Milling Chucks
Parfaite BT-PFC power milling chucks are built for heavy roughing cuts where maximum metal removal rates and high torque transfer are mandatory. Precision needle roller bearings inside the clamping nut minimize frictional resistance, preventing cutting tool slippage or pull-out.
- BT30, BT40, BT50 tapers with bore clamping sizes PFC20, PFC25 and PFC32
- Heavy rough milling of titanium alloys, stainless steels and forging dies
- Runout within 0.010 mm, cryogenically stabilized alloy steel tool body
- Heavy needle bearing nuts, interchangeable PFC collets and hook spanners
EIA and MIA High-Speed Built-in Motor Spindles
Parfaite EIA and MIA built-in motor spindles integrate high-frequency synchronous motors within a compact 120 mm outer diameter housing, delivering 7.5 kW power and ISO30 or HSK automatic tool changing. Designed for precision engraving and milling across high-speed spindle operations.
- EIA1275-24, EIA1037-30, MIA1037-30 and G1205-60 from 3.7 kW to 7.5 kW output
- High-speed 3D engraving, precision routing of aluminum and composite plates
- Wide operational velocity envelope with precision ceramic hybrid ball bearings
- Pneumatic tool release pistons, drawbar position sensors and cooling ports
MZ01 High-Speed Electric Spindle Speeders
Parfaite MZ01 spindle speed increasers convert standard CNC machining centers into high-speed mold making platforms without rotating the machine spindle. Driven by an independent high-frequency motor, the speeder delivers rapid tool rotation with low vibration for 24/7 continuous duty.
- Adapters for MZ01-BT30, MZ01-BT40, MZ01-BT50, MZ01-HSK63A and MZ01-ST32 mounts
- Micro-milling, fine corner cleaning and hardened mold cavity detailing
- Broad operational speed regulation with minimal drive noise and low vibration
- Dedicated inverter drives, power connection cables, stop blocks and collets
Selecting Parfaite HER Collet Chucks and BT-HY Hydraulic Tool Holders
Parfaite HER precision collet chucks are engineered for high-feed and high-speed CNC milling.
Featuring an innovative trapezoidal thread profile on the clamping nut, the tooling system delivers up to 2.3 times higher clamping torque compared to standard ER holders while maintaining runout within 0.005 mm.
For vibration damping during mold finishing and high-speed reaming, Parfaite BT-HY hydraulic expansion holders utilize pressurized hydraulic chambers to provide uniform 360-degree grip.
The internal fluid volume absorbs cutting vibration, protecting micro-grain carbide cutting tool edges and improving surface roughness.
Integrating High-Speed EIA Motor Spindles and MZ01 Speed Increasers
Parfaite EIA and MIA built-in motorized spindle units deliver up to 7.5 kW power and ISO30 or HSK automatic tool changing within a compact 120 mm outer diameter housing.
Ceramic hybrid bearings and liquid cooling channels maintain thermal equilibrium across high-velocity rotation envelopes for precision engraving.
To upgrade standard vertical milling machines without spindle modifications, Parfaite MZ01 spindle speeders provide independent high-frequency motor drive for rapid tooling rotation.
The main machine spindle remains stationary, eliminating gear noise and allowing continuous 24/7 fine corner cleaning and detailed mold cavity machining.
